Write value-parameterzied tests Step 1: Define a fixture class. ◦ Be derived from ::testing::TestWithParam
T can be any copyable type. If it's a raw pointer, you are responsible for managing the lifespan of the pointed values.
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.
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.
Functions for generating test parameters all in the testing namespace:
