# We recommend enforcing a policy that keeps your CI from being slowed down
# by individual test targets that should be optimized
# or split up into multiple test targets with sharding or manually.
# Set this flag to exclude targets that have their timeout set to eternal (>15m) from running on CI.
# Docs: https://bazel.build/docs/user-manual#test-timeout-filters
build --test_timeout_filters=-eternal

# Set this flag to enable re-tries of failed tests on CI.
# When any test target fails, try one or more times. This applies regardless of whether the "flaky"
# tag appears on the target definition.
# This is a tradeoff: legitimately failing tests will take longer to report,
# but we can paper over flaky tests that pass most of the time.
# The alternative is to mark every flaky test with the `flaky = True` attribute, but this requires
# the buildcop to make frequent code edits.
# Not recommended for local builds so that the flakiness is observed during development and thus
# is more likely to get fixed.
# Note that when passing after the first attempt, Bazel will give a special "FLAKY" status.

# Announce all announces command options read from the bazelrc file(s) when starting up at the
