ctest run specific test

To run a specific test in C using CTest, you can follow these steps:

1. Open your terminal or command prompt and navigate to the directory where your C project is located.

2. Build your project using the appropriate build command. This could be make, gcc, or any other build tool depending on your project setup. Make sure your project is successfully built before proceeding to the next step.

3. Once your project is built, you can use the ctest command to run the tests. By default, running ctest without any arguments will run all the tests in your project.

4. To run a specific test, you can use the -R or --tests-regex option followed by a regular expression that matches the name of the test you want to run. For example, if you have a test named "test_function", you can run it using the following command: ctest -R test_function

This command will run only the test that matches the regular expression "test_function".

1. After running the test, you will see the test output in the terminal. The output will indicate whether the test passed or failed, along with any additional information or error messages.

Please note that the specific steps may vary depending on your project setup and the testing framework you are using. The steps provided here are general guidelines for running a specific test using CTest.
