• Analyzing Test Fixture Smells with TestHound

    Designing automated tests is a challenging task. One important concern is how to design test fixtures, i.e. code that initializes and configures the system under test so that it is in an appropriate state for running particular automated tests. Test designers may have to choose between writing in-line fixture code for each test or refactor fixture code so that it can be reused for other tests. Deciding on which approach to use is a balancing act, often trading off maintenance overhead with slow test execution. Additionally, over time, test code quality can erode and test smells can develop, such as the occurrence of overly general fixtures, obscure in-line code and dead fields. Test smells are poor solutions to recurring implementation and design problems in test code. Until now, no support has been made available to developers during the analysis and adjustment of test fixtures.
    To address this shortcoming, we developed a TestHound. TestHound automatically analyzes test fixtures to detect fixture-related smells and guides improvement activities.
