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.
