Is there a way to force Bazel to run tests serially

Question

By default, Bazel runs tests in a parallel fashion to speed things up. However, I have a resource (GPU) that can't handle parallel jobs due to the GPU memory limit. Is there a way to force Bazel to run tests in a serial, i.e., non-parallel way?

Thanks.

Answer 1

--jobs 1 will limit the number of parallel jobs Bazel runs to 1.

You can also modify the test targets and add tags = ["exclusive"] to prevent specific test to run in parallel (see https://bazel.build/reference/test-encyclopedia).
