Please use this workflow to address this flaky test issue, including checking applicable checkboxes and filling in the applicable "TODO" entries:

• Is this actually a flaky test?

  • No, this is a regular test failure, fix the test/product (TODO: Link to commit/PR)
  • Yes, proceed below...

• Is this test failure caused by product code flakiness? (Either this product, or another product this test depends on.)

  • File a bug against the product (TODO: Link to other bug)
  • Is it possible to change the test to avoid the flakiness?
    • Yes? Go to the "Change the test!" section.
    • No?
      • Disable the test (TODO: Link to PR/commit)
      • Wait for other bug to be resolved
      • Wait for us to get build that has the fix
      • Re-enable our test (TODO: Link to PR/commit)
      • Close this bug

• Is it that the test itself is flaky? This includes external transient problems (e.g. remote server problems, file system race condition, etc.)

  • Is there is a way to change our test to avoid this flakiness?
    • Yes? Change the test!
      • Change the test to avoid the flakiness, for example by using a different test strategy, or by adding retries w/ timeouts (TODO: Link to PR/commit)
      • Run the test 100 times locally as a sanity check.
      • Close this bug
    • No?
      • Delete the test because flaky tests are not useful (TODO: Link to PR/commit)
