Allow sharded execution for bazel test sharding support #2257

merged 4 commits into from Oct 27, 2021

Commits on Oct 27, 2021

  1. Allow test sharding for e.g. Bazel test sharding feature 

    This greatly simplifies running Catch2 tests in single binary
in parallel from external test runners. Instead of having to
shard the tests by tags/test names, an external test runner
can now just ask for test shard 2 (out of X), and execute that
in single process, without having to know what tests are actually
in the shard.

Note that sharding also applies to test listing, and happens after
tests were ordered according to the `--order` feature.
