How can I exclude a source named test.js from being detected to be test file in a create react app?

In a create-react-app application, I have named a source file :

/src/config/env/test.js

Unfortunately, jest is now trying to execute it as a test,

I have tried to add the following in my package.json:

"jest": {
    "collectCoverageFrom": [
      "!<rootDir>/src/config/env/test.js",
      "!<rootDir>/node_modules/"
    ]
}

But I still have this error:

FAIL src/config/env/test.js
  ● Test suite failed to run

    Your test suite must contain at least one test.

      at node_modules/jest/node_modules/jest-cli/build/TestScheduler.js:256:22

I am using react-scripts 2.1.3

Solution

  • The simplest solution here would be using the testPathIgnorePatterns configuration value, like this:

    "testPathIgnorePatterns": ["\/test.js"]
