To run a specific unit test using make with CMake, you need to first build the test target using CMake. This can be done by specifying the test target in your CMakeLists.txt file using add_test and add_executable commands.
Once you have defined your test target in the CMakeLists.txt file, you can use the make command to build the project as usual. After building the project, you can run the specific unit test by using the ctest command followed by the name of the test target.
For example, if you have a test target named "my_test", you can run the specific unit test by entering the following command in your terminal:
1
|
ctest -R my_test
|
This will run only the specified unit test named "my_test" using the make command with CMake.

How to specify the test target in cmake for unit testing?
To specify the test target in CMake for unit testing, you can follow these steps:
- Use the enable_testing() command to enable testing in your CMake project.
- Use the add_executable() command to create an executable target for your unit tests.
- Use the target_link_libraries() command to link the necessary libraries for your unit tests.
- Use the add_test() command to add a new test to the project.
- Specify the test name, the executable target, and any additional arguments for the test.
- You can also use the gtest_add_tests() command if you are using the Google Test framework in your project.
Here is an example of how to specify the test target in CMake for unit testing:
1 2 3 4 5 6 7 8 9 10 11 |
# Enable testing enable_testing() # Add an executable target for unit tests add_executable(my_unit_tests test/test_main.cpp test/test_case.cpp) # Link necessary libraries (e.g. Google Test) target_link_libraries(my_unit_tests gtest gtest_main) # Add a test add_test(NAME MyTest COMMAND my_unit_tests) |
This example shows how to create a test target called my_unit_tests and add a test named MyTest to the project. Make sure to adjust the file names and dependencies according to your project structure and requirements.
What is the purpose of running a specific test case in cmake?
The purpose of running a specific test case in CMake is to verify that a particular aspect of the software or code being developed functions as expected. Running the test case allows developers to check for errors, bugs, or discrepancies in the code and ensure that the software behaves as intended in different scenarios. This helps to validate the functionality of the code and ensure its overall quality and reliability.
What is the command to run unit tests in parallel in cmake?
To run unit tests in parallel in CMake, you can use the command ctest -j <number_of_jobs> where <number_of_jobs> is the maximum number of tests to run simultaneously. This command will execute the tests in parallel, speeding up the testing process.
How to set up a timeout for unit tests in cmake?
To set up a timeout for unit tests in CMake, you can use the TIMEOUT argument when defining your test with the add_test command.
Here is an example of how to set a timeout for a unit test in CMake:
1 2 3 4 5 |
add_test( NAME my_test COMMAND my_test_executable TIMEOUT 10 # set timeout to 10 seconds ) |
In this example, my_test is the name of the test and my_test_executable is the command to run the test executable. The TIMEOUT argument specifies the maximum time the test is allowed to run before being considered failed (in this case, 10 seconds).
You can adjust the timeout value to suit your specific test requirements. This timeout setting will help prevent tests from hanging indefinitely and will provide feedback if a test takes longer than expected to complete.
