# NOTE: We must use `pkgs.runCommand` instead of `testers.runCommand` for negative tests -- those wrapped with
# `testers.testBuildFailure`. This is due to the fact that `testers.testBuildFailure` modifies the derivation such that
# it produces an output containing the exit code, logs, and other things. Since `testers.runCommand` expects the empty
# derivation, it produces a hash mismatch.
