  • Monitoring long-running tests by intermediary logging of results

    By on October 2, 2018

    Motivation The set of tests being run on an application tends to grow as more features are added, or more bugs are fixed. This comes at the cost of execution times: for example, a test suite that took 30 min could now take 2 hours. Since normal logging info/test results...

  • Find unused functions in C/C++ code with coverage analysis

    By on September 18, 2018

    Unused functions impact maintenance Unused functions in a software project can cause code bloat, but they also create more work for the developers of tests, especially in the situation where code coverage (the quality) of tests is being measured. If a function is not used, then removing it from...
