I am trying to run my Jest unit tests in Team City but I always end up getting the prompt as shown below.
No tests found related to files changed since last commit.
Press `a` to run all tests, or run Jest with `--watchAll`.
Watch Usage
› Press a to run all tests.
› Press f to run only failed tests.
› Press p to filter by a filename regex pattern.
› Press t to filter by a test name regex pattern.
› Press q to quit watch mode.
› Press Enter to trigger a test run.
I tried running yarn test a to run all the tests. But once the tests have completed execution, I'm still getting the same prompt. I tried yarn test a q but that doesn't work. I also tried yarn test a --forceExit and yarn test a --bail but nothing happens, I still get the prompt. How can I run all my Jest tests without getting this prompt as there will be no interaction when running through Team City? Any help would be much appreciated.
In TeamCity, edit the setting for your configuration, then select Parameters on the side.
Click Add a new Parameter, and in the dialog popup that appears, under Kind: select Environment variable (env.).
Set the name to env.CI and set the value to true. Click Save.
Next time you run your build, your build should auto-run the tests and move on.
For bonus points (and if you are the administrator) go to Administration then under Projects edit the <Root project>. Click Parameters on the side and set the env.CI parameter to true so you don't have to set this for future projects.
