This project demonstrates how to test a C library with GoogleTest and Bazel.

• Install Bazel

• Run the following command:

bazel test --test_output=all //tests:CalcTests

If you'd like to debug your library, build the tests with the -c dbg flag:

bazel build //tests:CalcTests -c dbg

Then you can debug with GDB:

gdb bazel-bin/tests/CalcTests

The existing launch.json and tasks.json configs in .vscode/ should enable traditional debugging of the entire test suite. Just set your breakpoints and press F5.

The C++ TestMate extension enables a nice interface for running, viewing, and debugging individual test cases, but requires some additional configuration for Bazel compatibility.

If using that extension, you'll need to edit the advancedExecutables setting to contain the following:

    "testMate.cpp.test.advancedExecutables": [
      {
        "pattern": "{bazel-bin,build,Build,BUILD,out,Out,OUT}/**/*{test,Test,TEST}*",
        "sourceFileMap": { "/proc/self/cwd": "${workspaceFolder}" },
      }
    ]

Ideally, editing advancedExecutables should not be necessary. You should only need to add the bazel-bin pattern to the testMate.cpp.test.executables setting, and the sourceFileMap setting should have been picked-up from launch.json.

Once configured, you should be able to debug individual test cases by clicking on the debug icon in the Testing sidebar.
