Brick and Mortar stores have a lot of software in their operations. From supply chain to ordering, point of sale, inventory management, customer procurement and customer satisfaction, that's a lot of moving pieces to keep track of. It's a challenging endeavor to keep it all together, and QualiTest's Mike Hershkovitz joins Matt and Jess to talk about the ins and outs or testing for the retail space. Also, in a separately recorded segment, the Amazon purchase of Whole Foods and what it might mean is discussed by Matt, Perze, Justin and Michael. Is it really an additional 400-plus Amazon distribution centers, or is there something else going on here? Resourced by QualiTest Group

This report presents Space and Naval Warfare Systems Center Pacific's (SSC Pacific) preliminary efforts to implement and test the JANUS acoustic communication protocol onto a software-defined acoustic modem previously developed by engineers working at the Center. The SSC Pacific developed acoustic modem serves as an ideal open platform suitable for testing and evaluating physical layer protocols such as JANUS, which has recently become a North Atlantic Treaty Organization (NATO) adopted standard. The system configuration, implementation approach, laboratory, tank, and field tests at SSC Pacific's Transducer Evaluation Center (TRANSDEC) facility are discussed. The outcome of the preliminary testing and several lessons learned have paved the path for a promising future effort to create an integrated software-defined interoperable solution for the U.S. Navy's underwater acoustic communication operations with NATO and non-NATO military and civilian maritime assets.

This report surveys the field of software testing, and suggests applications to the testing practices of the United States Army Computer Systems Command. Its emphasis is on the practical aspects of testing, as they are seen by working programmers. Other studies which have addressed management issues are briefly examined. The study is addressed to the actual Computer Systems Command environment. Therefore, a good deal of the research literature on testing is irrelevant. A few comments that characterize impractical research are included to give direction to those examining the literature. Recommendations whose implementation would require substantial changes in resources have been avoided. It is assumed that the Computer Systems Command can move gradually to a better employment of its testing effort, but that no substantial increase in the resources devoted to testing can occur.

Program testing is studied for maximizing the reliability of computer programs. Several formulas are derived to estimate the number of tests required to say that a program being tested is correct with a given probability. Strategies to select those test cases which minimize the probability of program error while keeping the number of tests fixed, are investigated. (author)

A data acquisition software program developed to operate in conjunction with the automated control system of the 25 kW PM Electric Power System Breadboard Test facility is described. The proram provides limited interactive control of the breadboard test while acquiring data and monitoring parameters, allowing unattended continuous operation. The breadboard test facility has two positions for operating separate configurations. The main variable in each test setup is the high voltage Ni-Cd battery.

NASA's Space Launch System (SLS) is an advanced launch vehicle for a new era of exploration beyond earth's orbit (BEO). The world's most powerful rocket, SLS, will launch crews of up to four astronauts in the agency's Orion spacecraft on missions to explore multiple deep-space destinations. Boeing is developing the SLS core stage, including the avionics that will control vehicle during flight. The core stage will be built at NASA's Michoud Assembly Facility (MAF) in New Orleans, LA using state-of-the-art manufacturing equipment. At the same time, the rocket's avionics computer software is being developed here at Marshall Space Flight Center in Huntsville, AL. At Marshall, the Flight and Ground Software division provides comprehensive engineering expertise for development of flight and ground software. Within that division, the Software Systems Engineering Branch's test and verification (T&V) team uses an agile test approach in testing and verification of software. The agile software test method opens the door for regular short sprint release cycles. The idea or basic premise behind the concept of agile software development and testing is that it is iterative and developed incrementally. Agile testing has an iterative development methodology where requirements and solutions evolve through collaboration between cross-functional teams. With testing and development done incrementally, this allows for increased features and enhanced value for releases. This value can be seen throughout the T&V team processes that are documented in various work instructions within the branch. The T&V team produces procedural test results at a higher rate, resolves issues found in software with designers at an earlier stage versus at a later release, and team members gain increased knowledge of the system architecture by interfacing with designers. SLS Flight Software teams want to continue uncovering better ways of developing software in an efficient and project beneficial manner. Through agile testing, there has been increased value through individuals and interactions over processes and tools, improved customer collaboration, and improved responsiveness to changes through controlled planning. The presentation will describe agile testing methodology as taken with the SLS FSW Test and Verification team at Marshall Space Flight Center.

The Spaceport Command and Control System (SCCS) is the National Aeronautics and Space Administration's (NASA) launch control system for the Orion capsule and Space Launch System, the next generation manned rocket currently in development. This system requires high quality testing that will measure and test the capabilities of the system. For the past two years, the Exploration and Operations Division at Kennedy Space Center (KSC) has assigned a group including interns and full-time engineers to develop automated tests to save the project time and money. The team worked on automating the testing process for the SCCS GUI that would use streamed simulated data from the testing servers to produce data, plots, statuses, etc. to the GUI. The software used to develop automated tests included an automated testing framework and an automation library. The automated testing framework has a tabular-style syntax, which means the functionality of a line of code must have the appropriate number of tabs for the line to function as intended. The header section contains either paths to custom resources or the names of libraries being used. The automation library contains functionality to automate anything that appears on a desired screen with the use of image recognition software to detect and control GUI components. The data section contains any data values strictly created for the current testing file. The body section holds the tests that are being run. The function section can include any number of functions that may be used by the current testing file or any other file that resources it. The resources and body section are required for all test files; the data and function sections can be left empty if the data values and functions being used are from a resourced library or another file. To help equip the automation team with better tools, the Project Lead of the Automated Testing Team, Jason Kapusta, assigned the task to install and train an optical character recognition (OCR) tool to Brandon Echols, a fellow intern, and I. The purpose of the OCR tool is to analyze an image and find the coordinates of any group of text. Some issues that arose while installing the OCR tool included the absence of certain libraries needed to train the tool and an outdated software version. We eventually resolved the issues and successfully installed the OCR tool. Training the tool required many images and different fonts and sizes, but in the end the tool learned to accurately decipher the text in the images and their coordinates. The OCR tool produced a file that contained significant metadata for each section of text, but only the text and coordinates of the text was required for our purpose. The team made a script to parse the information we wanted from the OCR file to a different file that would be used by automation functions within the automated framework. Since a majority of development and testing for the automated test cases for the GUI in question has been done using live simulated data on the workstations at the Launch Control Center (LCC), a large amount of progress has been made. As of this writing, about 60% of all of automated testing has been implemented. Additionally, the OCR tool will help make our automated tests more robust due to the tool's text recognition being highly scalable to different text fonts and text sizes. Soon we will have the whole test system automated, allowing for more full-time engineers working on development projects.

A computer program generates a graphical user interface that, in combination with its other features, facilitates the acquisition and preprocessing of experimental data on the strain response, hysteresis, and power consumption of a multilayer composite-material structural component containing one or more built-in sensor(s) and/or actuator(s) based on piezoelectric materials. This program runs in conjunction with Lab-VIEW software in a computer-controlled instrumentation system. For a test, a specimen is instrumented with appliedvoltage and current sensors and with strain gauges. Once the computational connection to the test setup has been made via the LabVIEW software, this program causes the test instrumentation to step through specified configurations. If the user is satisfied with the test results as displayed by the software, the user activates an icon on a front-panel display, causing the raw current, voltage, and strain data to be digitized and saved. The data are also put into a spreadsheet and can be plotted on a graph. Graphical displays are saved in an image file for future reference. The program also computes and displays the power and the phase angle between voltage and current.

AUTOSIM is a software tool which automates the repetitive run testing of software. This tool executes programming tasks previously performed by a programmer with one year of programming experience. Use of the AUTOSIM tool requires a knowledge base containing information about known faults, code fixes, and the fault diagnosis-correction process. AUTOSIM can be considered as an expert system which replaces a low level of programming expertise. Reference information about the design and implementation of the AUTOSIM software test tool provides flowcharts to assist in maintaining the software code and a description of how to use the tool.

Software Engineering is a knowledge intensive activity that involves defining, designing, developing, and maintaining software systems. In order to build effective systems to support Software Engineering activities, Artificial Intelligence techniques are needed. The application of Artificial Intelligence technology to Software Engineering is called Knowledge-based Software Engineering (KBSE). The goal of KBSE is to change the software life cycle such that software maintenance and evolution occur by modifying the specifications and then rederiving the implementation rather than by directly modifying the implementation. The use of domain knowledge in developing KBSE systems is crucial. Our work is mainly related to one area of KBSE that is called automatic specification acquisition. One example is the WATSON prototype on which our current work is based. WATSON is an automatic programming system for formalizing specifications for telephone switching software mainly restricted to POTS, i.e., plain old telephone service. Our current approach differentiates itself from other approaches in two antagonistic ways. On the one hand, we address a large and complex real-world problem instead of a 'toy domain' as in many research prototypes. On the other hand, to allow such scaling, we had to relax the ambitious goal of complete automatic programming, to the easier task of automatic testing.

A method of automated testing of software has been developed that provides an alternative to the conventional mostly manual approach for software testing. The method combines (1) automated generation of test cases on the basis of systematic exploration of the input domain of the software to be tested with (2) run-time analysis in which execution traces are monitored, verified against temporal-logic specifications, and analyzed by concurrency-error-detection algorithms. In this new method, the user only needs to provide the temporal logic specifications against which the software will be tested and the abstract description of the input domain.

Two algorithms have been conceived to enable automated, thorough testing of Built-in test (BIT) software. The first algorithm applies to BIT routines that define pass/fail criteria based on values of data read from such hardware devices as memories, input ports, or registers. This algorithm simulates effects of errors in a device under test by (1) intercepting data from the device and (2) performing AND operations between the data and the data mask specific to the device. This operation yields values not expected by the BIT routine. This algorithm entails very small, permanent instrumentation of the software under test (SUT) for performing the AND operations. The second algorithm applies to BIT programs that provide services to users application programs via commands or callable interfaces and requires a capability for test-driver software to read and write the memory used in execution of the SUT. This algorithm identifies all SUT code execution addresses where errors are to be injected, then temporarily replaces the code at those addresses with small test code sequences to inject latent severe errors, then determines whether, as desired, the SUT detects the errors and recovers

Arena testing is a widely used tool to characterize the spatial distribution of fragments upon detonation of different types of cased munitions. A semi-circular layout of 19 specially constructed capture packs was used to capture fragments created by each of two identical cased munitions. As a result, various images and data were constructed and collected that showed the spatial distribution of fragments from a cased munition including a panoramic image showing penetrations and their polar coordinates. With the panoramic image created, it was possible to calculate the percentage of fragments at any given location in the 180 degree span of the arena which helped to confirm predictions. Based upon the results of these tests, the information gathered has proven to be useful in several technology demonstrations for base hardening and protection. Having the capability to predict areas of concentrated fragment impact has enabled engineers to design structures to mitigate the effect of frag loading and its effect on the structure.

In the simulation world, software upgrade is more common than new development. Thus it is extremely important to ensure proper operation of the simulation model as it is enhanced. The big question is how does one keep the current model operating correctly while adding new capabilities? The Model Development Team at the Air Combat Environment Test and Evaluation Facility, Patuxent River Naval Air Station, Maryland, has developed an approach that is useful in making sure that the current simulation model keeps its current capabilities operating correctly as well as testing any new capability that is added. The purpose of this paper is to present the approach used by the Model Development Team to answer the question put forth. This paper discusses the software development and maintenance criteria used as the overarching guide for testing. The testing process used and how this process ensures that the model meets the criteria is then given. Specific test examples and expected output are provided as a model testing approach. Finally, the future of development testing for the Model Development Team is presented.

An experiment was performed in which executable assertions were used in conjunction with search techniques in order to test a computer program automatically. The program chosen for the experiment computes a position on an orbit from the description of the orbit and the desired point. Errors were inserted in the program randomly using an error generation method based on published data defining common error types. Assertions were written for the program and it was tested using two different techniques. The first divided up the range of the input variables and selected test cases from within the subranges. In this way a grid of test values was constructed over the program's input space. The second used a search algorithm from optimization theory. This entailed using the assertions to define an error function and then maximizing its value. The program was then tested by varying only a limited number of the input variables and a second time by varying all of them. The results indicate that this search testing technique was as effective as the grid testing technique in locating errors and was more efficient. In addition, the search testing technique located critical input values which helped in writing correct assertions. (Author)

This document, the second of two volumes, completes the report of a Lilly Endowment, Inc. funded project whose major objective was to establish a process for both teachers and students to be involved in the field testing or evaluation of microcomputer software. Workshops were held in nine Indiana school corporations where more than 2,300 students and 290 teachers completed evaluations of over 135 selected microcomputer programs. The programs were instructional in nature and included various formats: drill and practice, tutorial, simulations, and educational games. Included in this volume are the results of the field testing during the second year of the project, revised evaluation forms, and the methodology that can be adopted by teachers. The contents include: (1) a list of programs by subject areas; (2) a list of programs by grade level; (3) the evaluations for 77 software programs; (4) a step-by-step process for the effective selection of microcomputer software; (5) a methodology for teacher and student evaluation of software; (6) questions and answers from an analysis of the data; (7) recommendations of sources for computer software; and (8) revised evaluation forms. Each software program evaluation lists the title, intended audience and curriculum level, instructional method, producer and/or distributor, stated objectives, teacher evaluation, positive and negative comments, teacher overall rating, comments on program utilization, and student evaluation.

Testing on the Standard Automated Remote to AUTODIN Host (SARAH) project was a continuous process. Development testing provided a stabilizing environment for the project. The early design interfaces were done in the implementation code (Ada), developing confidence in both the language and software engineering techniques it supports. The Ada environment had the right tools to allow incremental building. The packaging concept provided a continuous testing platform ensuring functional isolation, verification of data integrity, and an immediate decrease in the opportunity for the introduction of errors. This supported the principles of modularity, high cohesion, and low coupling. Shared packages of tools made the subsystem developers more productive. Generics were used to reduce redundancy in the development of code. Our greatest testing problems occurred because of the tasking environment. The library management system and the vendor developed debug tools proved to be essential in development testing and integration. Testing of software is not affected as significantly by the language used as it is by the engineering applied during the design and development of the system.

This paper reports on the examination of 27 tools that provide for test management, problem reporting, and static and dynamic analysis of Ada code. It provides software development managers with information that will help them gain an understanding of the current capabilities of tools that are commercially available, the functionality of these tools, and how they can aid the development and support of Ada software. During the course of the examination, the static and dynamic analysis tools were applied to a sample Ada program in order to assess their functionality. The test management and problem reporting tools were also subject to a practical examination using vendor-supplied data. Each tool was then described in terms of its functionality, ease of use, and documentation and support. Problems encountered during the examination and other pertinent observations were also recorded. Available testing tools offer important opportunities for increasing software quality and reducing development and support costs. The wide variety of functionality provided by tools in the same category, however, and, in some cases, lack of tool maturity, require careful tool selection on behalf of a potential user.

Results of research and development efforts are presented for Task 1, Phase 2 of a general project entitled, The Development of a Program Analysis Environment for Ada. A prototype of the QUEST/Ada system was developed to collect data to determine the effectiveness of the rule-based testing paradigm. The prototype consists of five parts: the test data generator, the parser/scanner, the test coverage analyzer, a symbolic evaluator, and a data management facility, known as the Librarian. These components are discussed at length. Also presented is an experimental design for the evaluations, an overview of the project, and a schedule for its completion.

And a brief overview of lessons learned.

We consider an approach to testing that combines white-box and black-box techniques. Black-box testing is used for testing a program's effects against its specification. White-box testing is essential if subtle implementation errors are to be identified, e.g., errors due to race conditions. Full white-box testing is a large task. However, for many properties, only a small portion of the program is relevant hence property-based testing has the potential to substantially simplify much of the testing work. The portion of a program that relates to a given property can be identified through slicing. We describe the ongoing development of a Tester's Assistant, which in the long term, will include a specification-driven slicer for C programs, a test data generator, a coverage analyzer, an execution monitor. The slicer and execution monitor are described in this paper, and applications to Unix security are indicated. Security is an important application of property-based testing because of the subtle undetected security errors in delivered operating systems. It is also a promising application because of the (unexpectedly) concise specifications that capture most security requirements, and because of the operating system support for execution monitoring.

A crucial step for either initial issue development or post deployment support updates of military software products is integrated systems testing. After the development team has conducted progressive coding/module level tests and appropriate systems integration tests (using a systems integration laboratory), a proposed new version for the software product emerges. The critical issue becomes 'Is this version ready for final operational testing and for release for use by our military users?'. During Developmental Test and Evaluation (DT&E), each proposed new version is subjected to integrated systems testing. The configuration item is installed into representatively configured military hardware system (aircraft, ships, etc.). During testing, it is operated in the near-operational environment (at sea or in flight, using highly skilled military operators performing a carefully planned representative task). The authors are team members of Naval Helicopter software development Integrated Program Teams (IPTs). Their pragmatic experiences in performing this value added testing in the near-operational environment is useful for consideration by all software developers and testers.

This Validation Summary Report describes the extent to which a specific Ada compiler conforms to the Ada Standard, ANSI/MIL-STD-1815A. This report explains all technical terms used within it and thoroughly reports the results of testing this compiler using the Ada Compiler Validation Capability. An Ada compiler must be implemented according to the Ada Standard, and any implementation-dependent features must conform to the requirements of the Ada Standard. The Ada Standard must be implemented in its entirety, and nothing can be implemented that is not in the standard. Even though all validated Ada compilers conform to the Ada Standard, it must be understood that some differences do exist between implementations. The Ada Standard permits some implementation dependencies--for example, the maximum length of identifiers or the maximum values of integer types. Other differences between compilers result from the characteristics of particular operating systems, hardware, or implementation strategies. All the dependencies observed during the process of testing this compiler are given in this report. The information in this report is derived from the test results produced during validation testing. The validation process includes submitting a suite of standardized tests, the ACVC, as inputs to an Ada compiler and evaluating the results.

Testing is an expensive but essential part of any software project. Having the right methods to detect faults is a primary factor for success in the software industry. Component based systems are problematic because they are prone to unexpected interaction faults, yet these may be left undetected by traditional testing techniques. In all but the smallest of systems, it is not possible to test every component interaction. One can use a reduced test suite that guarantees to include a defined subset of interactions instead. A well studied combinatorial object, the covering array, can be used to achieve this goal. Constructing covering arrays for a specific software system is not always simple and the resulting object may not closely mirror the real test environment. Not only are new methods for building covering arrays needed, but new tools to support these are required as well. Our aim is to develop methods for building smaller test suites that provide stronger interaction coverage, while retaining the flexibility required in a practical test suite. We combine ideas from combinatorial design theory, computational search, statistical design of experiments and software engineering. We begin with a description of a framework for greedy algorithms that has formed the basis for several published methods and a widely used commercial tool. We compare this with a meta-heuristic search algorithm, simulated annealing. The results suggest that simulated annealing is more effective at finding smaller test suites, and in some cases improves on combinatorial methods as well. We then develop a mathematical model for variable strength interaction testing. This allows us to balance the cost and the time of testing by targeting individual subsets of components. We present construction techniques using meta-heuristic search and provide the first known bounds for objects of this type. We end by presenting some new cut-and-paste techniques that merge recursive combinatorial constructions

The conversion from homogeneous global system for mobile communications (GSM) networks to heterogeneous GSM/universal mobile telecommunications system (UMTS) networks is rapidly expanding. Previous research identified vulnerabilities in the GSM network that were fixed in the UMTS standard; however, the mobile device must successfully access the UMTS network to take advantage of security improvements. Therefore, a possible vulnerability not addressed in either the GSM or UMTS standards is the potential for a malicious entity to prevent a mobile device from handing over from a GSM to UMTS network, because the GSM network maintains the standalone dedicated control channel (SDCCH) uplink time slots. The process of testing this vulnerability requires the development of a device that monitors a GSM base transceiver station, identifies when a handover to UMTS message is sent, tracks the time slots of the SDCCH uplink, and transmits a GSM handover-failure message. In this thesis, we present an open-source coding scheme that utilizes parts of the OpenBTS source code to transmit a GSM handoverfailure message using the universal software radio peripheral. The method is validated through the collection of the GSM transmitter messages by Airprobe s GSM-receiver software.

Formal Concept Analysis (FCA) provides us with algorithms of deriving formal ontology from a set of objects and their attributes. With the use of FCA we can considerably improve the efficiency of test case derivation. Moreover, an FCA-based machine learning system supports the analysis of regression testing results.

INTRODUCTION TO TESTING

This article is from PeerJ , volume 2 . Abstract Purpose. To design and validate a prenatal chromosomal microarray testing strategy that moves away from size-based detection thresholds, towards a more clinically relevant analysis, providing higher resolution than G-banded chromosomes but avoiding the detection of copy number variants (CNVs) of unclear prognosis that cause parental anxiety.Methods. All prenatal samples fulfilling our criteria for karyotype analysis (n = 342) were tested by chromosomal microarray and only CNVs of established deletion/duplication syndrome regions and any other CNV >3 Mb were detected and reported. A retrospective full-resolution analysis of 249 of these samples was carried out to ascertain the performance of this testing strategy.Results. Using our prenatal analysis, 23/342 (6.7%) samples were found to be abnormal. Of the remaining samples, 249 were anonymized and reanalyzed at full-resolution; a further 46 CNVs were detected in 44 of these cases (17.7%). None of these additional CNVs were of clear clinical significance.Conclusion. This prenatal chromosomal microarray strategy detected all CNVs of clear prognostic value and did not miss any CNVs of clear clinical significance. This strategy avoided both the problems associated with interpreting CNVs of uncertain prognosis and the parental anxiety that are a result of such findings.

Developing multithreaded software is an extremely challenging task, even for experienced programmers. The challenge does not end after the code is written. There are other tasks associated with a development process that become exceptionally hard in a multithreaded environment. A good example of this is creating unit tests for concurrent data structures. In addition to the desired test logic, such a test contains plenty of synchronization code that makes it hard to understand and maintain. In our work we propose a novel approach for specifying and executing schedules for multithreaded tests. It allows explicit specification of desired thread scheduling for some unit test and enforces it during the test execution, giving the developer an ability to construct deterministic and repeatable unit tests. This goal is achieved by combining a few basic tools available in every modern runtime/IDE and does not require dedicated runtime environment, new specification language or code under test modifications.

It allows explicit specification of desired thread scheduling for some unit test and enforces it during the test execution, giving the developer an ability to construct deterministic and repeatable unit tests. This goal is achieved by combining a few basic tools available in every modern runtime/IDE and does not require dedicated runtime environment, new specification language or code under test modifications.

Developing multithreaded software is an extremely challenging task, even for experienced programmers. The challenge does not end after the code is written. There are other tasks associated with a development process that become exceptionally hard in a multithreaded environment. A good example of this is creating unit tests for concurrent data structures.

The large adoption of wireless devices goes further than WiFi (smartmeters, wearable devices, Internet of Things, etc.). The developers of these new types of devices may not have a deep security background and it can lead to security and privacy issues when the solution is stressed. However, to assess those types of devices, the only solution would be a dedicated hardware component with an appropriate radio interface for each one of them. That is why we developed an easy-to-use wireless monitor/injector tool based on Software Defined Radio using GNU Radio and the well-known scapy framework. In this talk, we will introduce this tool we developed for a wide range of wireless security assessments: the main goal of our tool is to provide effective penetration testing capabilities for security auditors with little to no knowledge of radio communications.
