The code for this recipe is available at https://github.com/dev-cafe/cmake-cookbook/tree/v1.0/chapter-04/recipe-09. The recipe is valid with CMake version 3.5 (and higher), and has been tested on GNU/Linux, macOS, and Windows.
In the previous recipe, we learned how to run tests in parallel with the help of CMake, and we discussed that it is advantageous to start with the longest tests. While this strategy minimizes the total test time, during the code development of a particular feature, or during debugging, we may not wish to run the entire test set. We may prefer to start with the longest tests, especially while debugging functionality that is exercised by a short test. For debugging and code development, we need the ability to only run a selected subset of tests. In this recipe, we will present strategies to accomplish that.
