6. Write value-parameterzied tests
Step 1: Define a fixture class.
Be derived from ::testing::TestWithParam<T>, where T is the type of your parameter values. 
TestWithParam<T> is itself derived from ::testing::Test. 
T can be any copyable type.
If it's a raw pointer, you are responsible for managing the lifespan of the pointed values.

7. Step 2: use the TEST_P macro
To define as many test patterns using this fixture as you want.
The _P suffix is for "parameterized" or "pattern", whichever you prefer to think.

8. Step 3: use INSTANTIATE_TEST_CASE_P
to instantiate the test case with any set of parameters you want.
Google Test defines a number of functions for generating test parameters.
They return what we call (surprise!) parameter generators.
