If your tests ran in a sandbox, for instance the Bazel sandbox or a Docker container, and this has the same configuration on CI and on the local machine, then it does not matter if the tests ran in CI or on a developer's machine. This falls apart for things like integration tests, which may be too large/complex/interconnected to work on a local machine, but most of the time this would be more than sufficient.
