Project name and goals
Presentation of TestCocoon at the "Qt Contributor’s Summit" in June 2011.
Description of TestCocoon
TestCocoon is a complete code coverage tool chain for C/C++ and C# programs available under AppleMac OS X, Linux™ or Microsoft® Windows. It analyzes the performance of a software validation and permits to measure the performance and optimizes the testing process of a C/C++ or C# applications:
- Finding untested code sections.
- Reducing the amount of tests by finding redundant tests.
With TestCocoon it is possible to find which portion of the source code is covered only by one execution of a test, and to detect if a new test does not cover more source code line than existing tests.
- Finding dead code trough displaying the code parts which are never executed.
- Specially useful for manual testing: TestCocoon is able to calculate the optimal execution order of tests which maximize the overall coverage after each run.
- Also, TestCocoon is able to perform its analysis on a difference of two applications.
This permits to find which tests are impacted by a source code modification and permits to measure the test quality of a patch or a hot fix.
TestCocoon can be uses for every testing steps and methodologies (unit tests, automatic tests, manual white box tests, black box tests, etc. . . ), and permits to collect and merge the execution reports together.
It is composed of 3 tools:
- CoverageScanner, which analyzes, instruments and generates the C/C++ or C# application.
- CoverageBrowser, which displays and manages the results of the coverage analysis. black box interactive tests.
- An optional Microsoft® Visual Studio® 2005 & 2008 Add-In which permits to generate code coverage configurations from every C/C++ projects created by Microsoft® Visual Studio®.
Relationship with Qt
- All tools except CoverageScanner are generated using the Qt framework.
- TestCocoon provides a specific code coverage analysis for Qt applications which permits:
- not instrument the contain of Q_OBJECT, Q_EXPORT_PLUGIN, Q_DECLARE_METATYPE, . . . macros.
- instrument the emission of a signal, but not the engine code generated my the moc compiler.
