CTest Lab
This extension is still a preview lacking some major functionality.
Why CTest Lab
There are other VS Code extensions tailored to specific test frameworks, such as Catch2 or gtest. CTest is not restricted to compiled executables using those frameworks, though. For example, you could have a test that runs a script to verify installation of your package. You could have a CTest fixture that downloads binary test data from the Internet. These types of tests and test relationships are not captured by other extensions.
