Generating Invalid Input Strings For Software Testing, Benjamin D. Revington
Generating Invalid Input Strings For Software Testing, Benjamin D. Revington
Electronic Thesis and Dissertation Repository
Grammar-based testing has interested the academic community for decades, but little work has been done with regards to testing with invalid input strings. For our research, we generated LR parse tables from grammars. We then generated valid and invalid strings based on coverage of these tables. We evaluated the effectiveness of these strings in terms of code coverage and fault detection by inputting them to subject programs which accept input based on the grammars. For a baseline, we then compared the effectiveness of these strings to a more general approach where the tokens making up each string are chosen randomly. …

Software testing is a crucial part of the software development process, because it helps developers ensure that the software works correctly and according to stakehold- ers’ requirements and specifications. Faulty or problematic software can cause huge financial losses. Automation of testing tasks can have a positive impact on software development, by reducing costs and minimizing human error. Software testing can be divided into three tasks: choosing test cases, running test cases on the software under test (SUT) and evaluating the test results. To evaluate test results, testers need to examine the output of the SUT to determine if it performed …
