Enhancing the test library to support Hamcrest matchers

Once you get a basic implementation working and passing the tests, TDD guides us to enhance the design by creating more tests and then getting the new tests to pass. That’s exactly what this chapter is all about. We’re enhancing the classic style confirmations to support the Hamcrest style.

Let’s start by creating a new file, called Hamcrest.cpp, in the tests folder. Now, the overall project structure should look like this:

MereTDD project root folder
    Test.h
    tests folder
        main.cpp
        Confirm.cpp
        Creation.cpp
        Hamcrest.cpp
        Setup.cpp
