If you're like us, you'd like to look at some Google Test sample code. The samples folder has a number of well-commented samples showing how to use a variety of Google Test features.

Sample #1 shows the basic steps of using Google Test to test C++ functions.
Sample #2 shows a more complex unit test for a class with multiple member functions.
Sample #3 uses a test fixture.
Sample #4 is another basic example of using Google Test.
Sample #5 teaches how to reuse a test fixture in multiple test cases by deriving sub-fixtures from it.
Sample #6 demonstrates type-parameterized tests.
Sample #7 teaches the basics of value-parameterized tests.
Sample #8 shows using Combine() in value-parameterized tests.
Sample #9 shows use of the listener API to modify Google Test's console output and the use of its reflection API to inspect test results.
Sample #10 shows use of the listener API to implement a primitive memory leak checker.
