Regression testing is any type of software testing, which seeks to uncover regression bugs. Regression bugs occur as a consequence of program changes. Regression testing must be conducted to confirm that recent program changes have not harmfully affected existing features and new tests must be created to test new features. Testers might rerun all test cases generated at earlier stages to ensure...

In order for a proficiency testing program to receive HHS approval, the program must be offered by a private nonprofit organization or a Federal or State agency, or entity acting as a designated agent for the State. An organization, Federal, or State program seeking approval or reapproval for its program for the next calendar year must submit an application providing the required information by...

Automated software test generation has been applied across the spectrum of test case design methods; this includes white-box (structural), black-box (functional), greybox (combination of structural and functional) and nonfunctional testing. In this paper, we undertake a systematic mapping study to present a broad review of primary studies on the application of search-based optimization techniqu...

White-box testing techniques based on control flow and data flow analysis have been widely studied in the software testing research literature, but there is no definitive answer to the question of how effective these techniques are at finding software faults. In the absence of data indicating how effective (and how expensive) these techniques are, it is hardly surprising that they have not been...

when testing a program, correctly executed test cases are seldom explored further, even though they may carry useful information. Metamorphic testing proposes to generate follow-up test cases to check important properties of the target function. It does not need a human oracle for output prediction and comparison. An “oracle” in software testing is a procedure by which testers can decide whethe...

With the rapid development of software scale and programming languages, it is impossible to test software manually. The case for automating the software testing process has been made repeatedly and convincingly by numerous testing professionals. Automated tests can promote the efficiency of software testing and then to increase software productivity, improve software quality, and reduce cost in...

Software testing is an expensive component of software development and maintenance. For data flow testing, test cases must be found t o test the def-use pairs in a program. Since some o f the def-use pairs identified through static analysis may be infeasible, no amount of testing effort may result in exhaustive testing of a program. Therefore in practice a fixed amount of effort is spent in tes...

A test data adequacy criterion is a predicate which is used to determine whether a program has been tested “enough.” An adequacy criterion is applicable if for every program there exists a set of test data for the program which satisfies the criterion. Most test data adequacy criteria based on path selection fail to satisfy the applicability property because, for some programs with unexecutable...
