How to do it...

To create and use a test fixture, do the following:

1. Create a class derived from the ::testing::Test class:

        class TestFixture : public ::testing::Test        {        };

2. Use the constructor to initialize the fixture and the destructor to clean it up:

        protected:          TestFixture()          {            std::cout << "constructing fixture" << std::endl;            data.resize(10);            std::iota(std::begin(data), std::end(data), 1);          }          ~TestFixture()          {            std::cout << "destroying fixture" << std::endl;          }

3. Alternatively, you can override the virtual methods SetUp() and TearDown() for the same purpose.
4. Add member data and functions to the class to make them available to the tests:

        protected:          std::vector<int> data;

5. Use the TEST_F macro to define tests using fixtures, and specify ...
