Flaky CI

Flaky CI #41

Workflow file for this run

# Run all tests, including flaky test.
#
# The default CI workflow ignores flaky tests. This workflow will run
# all tests, including ignored ones.
#
# To use this workflow you can either:
#
# - Label a PR with "flaky-test", the normal CI workflow will not run
# any jobs but the jobs here will be run. Note that to merge the PR
# you'll need to remove the label eventually because the normal CI
# jobs are required by branch protection.
#
# - Manually trigger the workflow, you may choose a branch for this to
# run on.
#
# Additionally this jobs runs once a day on a schedule.
#
# Currently doctests are not run by this workflow.
