Ignore a specific folder pattern in testMatch with Jest

I'm trying to ignore a specific folder in the testMatch pattern of Jest.

I have my tests in a __tests__ folder and I want to be able to have a folder __config__ into it with all files inside which should be ignored.

/__tests__
  /__config__
    someConfig.jsx
  /MyComponent.jsx
/MyComponent.jsx

My tests in the __tests__ folder will import the files from the __config__ folder so I don't want to ignore them with the transformIgnorePatterns.

But if I don't ignore the folder, Jest tries to run in the folder and returns an error:

FAIL src/components/__tests__/__config__/someConfig.jsx

Your test suite must contain at least one test.

I've tried a few different patterns but I can't find a way to ignore the __config__ folder

testMatch: [
  "**/__tests__/!(__config__)/**/*.(js)?(x)", // Doesn't work
  "**/__tests__/(**|!__config__)/*.(js)?(x)", // Doesn't work
  "**/__tests__/(**|?!__config__)/*.(js)?(x)", // Doesn't work
  "**/__tests__/{**,!__config__}/*.(js)?(x)", // Doesn't work
],

Any idea how I can ignore the sub-folder like this?

You can also exclude files in the testMatch array using negation !. For example:

'testMatch': [
    '**/__tests__/**/*.+(ts|tsx|js)',
    '!**/excludeMe.ts'
  ],

Note that the order matters.

Each glob pattern is applied in the order they are specified in the config. For example ["!/fixtures/", "/tests//.js"] will not exclude fixtures because the negation is overwritten with the second pattern. In order to make the negated glob work in this example it has to come after /tests//.js.

Try This pattern:

testMatch: ['**/--tests--/?(*.)(test).js?(x)'],

It is working for me. My folder structure is: --tests-- auth.test.js user.test.js Routes - - Anotherfolders.

Try to use testPathIgnorePatterns, instead.

If the test path matches any of the patterns, it will be skipped.

Use the string token to include the path to your project's root.
