Comparison of C++ unit test frameworks


Question

I know there are already a few questions regarding recommendations for C++ unit test frameworks, but all the answers did not help as they just recommend one of the frameworks but do not provide any information about a (feature) comparison.

I think the most interesting frameworks are CppUnit, Boost and the new Google testing framework. Has anybody done any comparison yet?

Accepted Answer

See this question for some discussion.

They recommend the articles: Exploring the C++ Unit Testing Framework Jungle, By Noel Llopis. And the more recent: C++ Test Unit Frameworks

I have not found an article that compares googletest to the other frameworks yet.

A new player is Google Test (also known as Google C++ Testing Framework) which is pretty nice though.

#include <gtest/gtest.h>

TEST(MyTestSuitName, MyTestCaseName) {
    int actual = 1;
    EXPECT_GT(actual, 0);
    EXPECT_EQ(1, actual) << "Should be equal to one";
}

Main features:

  • Portable
  • Fatal and non-fatal assertions
  • Easy assertions informative messages: ASSERT_EQ(5, Foo(i)) << " where i = " << i;
  • Google Test automatically detects your tests and doesn't require you to enumerate them in order to run them
  • Make it easy to extend your assertion vocabulary
  • Death tests (see advanced guide)
  • SCOPED_TRACE for subroutine loops
  • You can decide which tests to run
  • XML test report generation
  • Fixtures / Mock / Templates...
