We are using Bazel as our build system, so make sure to install bazel globally on your machine.
We are using Bazel build system. Everything is defined in BUILD files (+ one WORKSPACE file). Learn more about Bazel to know how to build specific targets, locate produced binaries and so on.
We are using Catch2 test framework.
While you can use Bazel to run specific tests, there is run-tests script to easily build and run all tests.
This runs tests through Bazel, which is recommended way to do it (by Bazel), but we do lose Catch2 output coloring.
If you want to run it purely through Catch2, without Bazel interfering, you can run binaries that are produced as a result of building Bazel cc_test targets. Let's say you have Bazel cc_test target my-test. You can then do: bazel build //test:my-test to build the binary and then bazel-bin/test/my-test to run it.
