Could you recommend any open source projects where the source is extensively tested with unit tests? [closed]

Answer 1

The Bazaar version control system is obsessive about automated testing. Unit testing, feature testing, integration testing, blackbox testing, test doubles testing, testing framework testing, parameterized test suites, platform-specific tests, etc.

This has all sorts of nice consequences for the project, but I must refrain here from undue VCS fanboying.

EDIT: oops, I did not notice you said you were interested in C++. Bazaar is a Python project.

Answer 2

I wouldn't call it extensively, but wxWidgets does some UnitTest with CppUnit.

Answer 3

The Chromium project.

Answer 4

AFAIK C++ Boost libraries - http://boost.org/ - have broadly covered code base, and a policy that every new piece of code must have unit tests with it. Might be worth checking.

Answer 5

The trucov project is an open source tool used to verify unit test coverage. The tool itself is extensively unit tested using google's test framework.

Disclaimer: though I did not write the project myself I did mentor the students who did.
