What if you decide to debug the test run via CTest? To avoid debugging the ctest child process, CLion runs the test itself under debug. The console output is shown on the right, and the Jump to Source action will navigate you to the CMakeLists.txt file where the test is declared. You can also show and hide successful and ignored tests, and rerun all failed tests in one click. You can launch tests via the configuration run, or use the run icon in the CMakeLists.txt file:ĬLion’s built-in test runner shows the test results, which you can sort alphabetically or by duration. For this, specify a -parallel value in the Program Arguments field. If your tests support that, you can run them in parallel. In the configuration, you can tune the set of tests to run: Let’s take the PEGTL project from GitHub for example and give it a try:Īlternatively, you can create a configuration manually if you select CTest Application type. When you first open a project that uses CTest, CLion detects the tests that are configured and automatically creates an All Tests configuration for running and debugging them. However, tests are launched via the ctest executable, which affects the results.ĭOWNLOAD CLION 2020.3 EAP Start working with CTest in CLion

Running tests with Valgrind Memcheck, Sanitizers, Code Coverage, and Profiler is supported for CTest. The debug in CLion omits the ctest executable launch – it launches and debugs the final test.Īll types of toolchains are supported, including remote toolchains and WSL. When several tests are joined under one CTest entry, the dialog to select a final test to debug is shown. With one click, you can navigate from the built-in test runner to the CMakeLists.txt. You can review the test results In the test runner. The left-hand gutter displays icons to run the tests in your CMakeLists.txt files.ĬLion can run the tests and present the results in its built-in test runner: The IDE automatically creates a Run/Debug configuration for them. The list of tests in CTest is read and processed by CLion: In this blog post, let’s look at how you can benefit from this support as you use CTest tests in CLion. We added support for CTest in CLion 2020.3 EAP. Our users often ask us if there’s a chance CLion could support CTest. Looking at CTest as a CMake-specific test runner, you may think of it as something similar to CLion’s built-in test runner (even though it isn’t quite a straightforward comparison). CTest, a testing tool distributed as part of CMake, is used to automate unit testing, which entails running tests and uploading the results to a dashboard. We also know that CMake is the most trending project model in the C++ world. CLion supports all of these, as well as doctest. Our latest global developer survey shows that Google Test, Catch2, and Boost.Test are the three most popular frameworks for unit testing.
