Retry failed jobs in github actions

Question

I'm trying to use GitHub Actions for CI testing, so far I have my test workflow as follows:

name: test

on: [push]

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v1
      - uses: actions/setup-node@v1
        with:
          node-version: 12
      - run: npm install
      - name: test
        run: |
          npm run lint
          npm test
        env:
          CI: true

.github/workflows/test.yml

It is working fine, except I want to retry the test step (or the whole job) once if the tests fails.

Basically, the same behavior you get with travis-retry:

script:
  - npm run lint
  - travis_retry npm test

or with Gitlab CI:

test:
  stage: test
  retry: 1
  script:
    - npm run lint
    - npm test

Not sure if there is a way for this or a reasonably simple workaround

Answer 1

For your particular use case, just do:

npm test || npm test

Answer 2

Action Retry seems to work well in my testing

I was able to use it with multi-part commands as long as they were single line (for example do-this && do-that)

Answer 3

I would say that you need to manage the retry logic on code level. Meaning, implement/integrate such mechanic to handle and execute again only the failed tests. I'm afraid simply

want to retry the test step (or the whole job) once if the tests fails.

will execute all your tests, may even overwrite outputs, like reports and logs from the first run.

In my experience, I have used a wrapper (shell) script. Here is how it could be achieved:

#!/usr/bin/env bash
{ # try
    # your npm test command here, that saves as output -  failed tests
} || { # catch
    # retry failed tests
      if [ -f ./rerun-failed-file ]; then
        echo "============= [WARN] Rerun file found! =============="
        echo "============= [WARN] Rerunning FAILED tests mode. =============="
        # run npm test command that picks up the failed tests & aggregate test artifacts
      fi
}
