Catch2 is a cross-platform testing framework. CLion supports Catch versions 1.7.2 and later. With dedicated Catch run/debug configurations, you can specify test names with wildcards or tags and then explore the results in the test runner window.
Adding Catch2 to your project
Download the latest version of catch.hpp header using the link from the documentation and copy it into your project tree.
Include the header in your test files:#include "catch.hpp"
In only one source file, precede the
CATCH_CONFIG_RUNNER(use the latter if you want to supply your own main()).
Catch run/debug configuration
To create a Catch configuration, go to Run | Edit Configurations, click and select Catch from the list of templates.
Specify the configuration settings:
Set the configuration name in the Name field. This name will be shown in the list of the available run/debug configurations.
Select the Tags/Test option to run a test for the particular tags or all the tags. Select the Pattern option to run all the tests for a particular pattern.
Specify tags in the tags fields. This option is available only when the Tags/Test option is selected.
Select the desired test from the Test drop down list. Note, that this option is available only when one or more tags have been provided.
Specify the pattern name in the Pattern field. Note, that this option is available only when the Pattern option is selected.
In the Target field, select the desired target from the list of available targets.
Save the configuration, and it's ready for Run or Debug.
