Software testing is any activity aimed at evaluating an attribute or capability of a program or system and determining that it meets its required results. [Hetzel88] Although crucial to software quality and widely deployed by programmers and testers, software testing still remains an art, due to limited understanding of the principles of software. The difficulty in software testing stems from t...

Federal authority over clinical laboratories began in 1966 when Medicare independent-laboratory regulations established personnel standards for laboratories that participated in the Medicare and Medicaid programs. The following year, Congress enacted the Clinical Laboratory Improvement Act of 1967, known as ‘tCLIA ‘67,” which required licensure for laboratories testing patients’ specimens in in...

Software testing can be stated as the process of validating and verifying that a computer program, application and product [1]. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Software testing, depending on the testing method employed, can be implemented at any time in the d...

Few studies have evaluated the impact of workplace substance abuse prevention programs on occupational injury, despite this being a justification for these programs. This paper estimates the effectiveness and benefit-cost ratio of a peer-based substance abuse prevention program at a U.S. transportation company, implemented in phases from 1988 to 1990. The program focuses on changing workplace a...

In this article, we consider model oriented formal specification languages. We generate test cases by performing symbolic execution over a model, and from the test cases obtain a Java program. This Java program acts as a test driver and when it is run in conjunction with the implementation then testing is performed in an automatic manner. Our approach makes the testing cycle fully automatic. Th...

We describe the outline of a method to retrieve a model from various program runs of object-oriented software which can then be used to find bugs in the program, re-design or refactor it, test the program against the model, perform regression testing and check if new code violates the model. When completed, the model extraction and testing will be implemented as an Eclipse plug-in and the progr...

This paper discusses computer-assisted generation of input data for program testing. The test data generation system must produce input data that is per specification, unbiased by prior analysis of the program to be tested. The test data generators evaluated use random generation techniques to produce the test data. To reduce the number of sets of test data needed to test a program, summary inf...

Software testing is about testing a feature with varying test data to get a result and then comparing the actual result with expected result. It is not merely finding defects or bugs in the software; it is the completely dedicated discipline of evaluating the quality of the software. Software testing efforts its goals or objectives but it does have certain limitations, still testing can be done...

Testing is a critical component of the software development process and is required to ensure the reliability, robustness and usability of software. Tools that systematically aid in the testing process are crucial to the development of reliable software. This paper describes a codebased testing and analysis tool for object-oriented software. TATOO provides a systematic approach to testing tailo...
