# This means that even though our build jobs write to
# `/artifact-mount`, the directory on the host machine is
# actually `/tmp/artifacts`.
# Here, we cat all text files in artifact-mount/test-summaries
# and upload them as a Buildkite annotation.
# These files contain a condensed summary of all failing pytest
# tests to make it easy for users to see which tests are failing.
# Because we upload them to Buildkite, we don't need to
# upload them as artifacts and delete them afterwards.
