Most modern computers have four or more CPU cores. One fantastic feature of CTest is its ability to run tests in parallel, if you have more than one core available. This can significantly reduce the total time to test, and reducing the total test time is what really counts, to motivate developers to test frequently. In this recipe, we will demonstrate this feature and discuss how you can optimize the definition of your tests for maximum performance.
