No tests found on 'ng test' with dot in the path to the root directory

Describe the bug When I do ng test - it doesn’t find any single test.

Firstly, I tried that on existing project (which is using jest but via jest cli and I know tests exist) -> 0 tests discovered. Then, I tried new project (via ng new) -> 0 tests discovered. At last, I downloaded simple-app example -> 0 tests discovered.

And I have no idea what I am doing wrong or haven’t configured properly.

Any ideas what’s the reason?

Ask for more information -> will provide information that might help.

To Reproduce (for instance, new project)

1. ng new jest-app
2. npm i -D jest @types/jest @angular-builders/jest
3. adjust angular.json to use new builder
4. npm run test -> ng test

Expected behavior All tests are discovered

Builder:

• @angular-builders/jest
• 8.2.0

Libraries

• angular-devkit/build-angular: from 0.802.2 to 0.803.19

Additional context

• node.js: 12.13.0

No, not enough. I ran through them and don’t see such errors.

I had the same issue, but it turns out that when a test fails, the test runner claims there were no tests found. In other words, the wrong error is given.
