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.
Contact person by Nokia: Bill King. Sandbox repository: Qt-Creator instrumented using TestCocoon on Gitorious
Presentation of TestCocoon:
- General presentation of code coverage technique.
- Features and design of TestCocoon.
- How to instrument Qt applications.
- Live demonstration of Qt-Creator instrumented with TestCocoon.
Open discussion with Qt-stakeholders:
- Integration in build systems (qmake, cmake, . . . ).
- Integration in Qt-Creator.
- Integration in continuous build server (Hudson, Pulse, . . . ).
- New idea, or features.
