Npm test never stops executing

I used create-react-app to bootstrap a new project and left it as it is by default.

Added GitHub actions config for node.js:

name: Build and Deploy
      - master
    runs-on: ubuntu-latest
      - name: Checkout
        uses: actions/checkout@master
      - name: Setup Node
        uses: actions/setup-node@v1
          node-version: '10.x'
      - run: npm ci
      - run: npm test

The code never passes the npm test step.

What am I doing wrong?

It seems that when you execute the command npm test , you should explicitly set the environment variable CI , no matter its value is true or false.

You can try the below 2 methods to set this environment variable:

  • Set CI directly in the command line, for example on Linux, macOS (Bash).

    CI=true npm test

  • Define CI as an environment variable in the workflow.

     CI: true

We can define it on workflow level, job level or step level, so that it can be available for different scopes.


Do you need both? CI=true npm test works but just setting the env var hangs when you add another command after the npm test

      - run: npm test
      - run: echo hangs in the line above even though the env var is set
          CI: true

      - run: CI=true npm test
      - run: echo works and pipeline continues
          CI: true

When just using env and I run -run: env I don’t see the CI var

when my workflow runs i have everything setup as you said but though it takes forever to run test

on local it works fine but on github it takes forever

For anybody still reading this.
I faced the same issue, found that I had --watch flag added to jest in the test script.
The test won’t end in that case. Removed and everything is fine.


[If you are still reading this article]
I have faced the same issue with angular “ng test” and followed below steps:

  1. set “singleRun: true” in karma.conf.js
  2. update the ng test in package.json to “ng test --browsers=ChromeHeadless”
  3. Changed the action workflow to [apt statement is for ubuntu, you can use the equivalent install statement for other platforms as well ]
          - run: sudo apt install chromium-browser

          - name: Install dependencies
            run: npm ci

          - name: NPM Test
            run: |
              export CHROME_BIN=/usr/bin/chromium-browser
              CI=true npm run test-headless
              CI: true

Problem was related to the missing chromium package on ubuntu runner. After installing the chromium and exporting the environment variable, test has started running.

Run sudo apt install chromium-browser

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
