The command "ctest -N" is typically used in CMake, a popular cross-platform build tool, for running tests on a project.

Here is a breakdown of the components in the command:

• "ctest": This is the command-line tool provided by CMake for running tests. It is used to manage and execute the tests defined in a CMake project.

• "-N": This is an option passed to ctest. In this particular case, "-N" stands for "test output only". By providing this option, ctest will display a list of available tests without actually executing them. It will show the test names, the relevant properties, and some additional information related to each test.

Overall, running the command "ctest -N" helps to retrieve information about the available tests in a CMake project, without executing them. This can be helpful for inspecting the test suite, understanding the test structure, or verifying the presence of specific tests.
