Encountering this error: Your test suite must contain at least one test?

I recently updated some dependencies in my project, and everything went smoothly. However, when I ran my tests before pushing, I encountered the following error:

“Your test suite must contain at least one test.”

What could be causing this issue, and how can I resolve it?

Hi,

Verify that your test directory contains actual test files and that these files include at least one valid test case. If you’re using a testing framework like Jest, Mocha, or Jasmine, make sure the test files follow the correct naming convention (e.g., *.test.js or *.spec.js) and contain at least one test(), it(), or equivalent function.

// example.test.js
test('should pass this test', () => {
  expect(true).toBe(true);
});

You can review the configuration of your test runner to ensure it’s correctly set up to recognize and run your tests.

For example, if you’re using Jest, ensure that the testMatch or testRegex properties in the Jest configuration match the file patterns of your test files.

// jest.config.js
module.exports = {
  testMatch: ["**/?(*.)+(spec|test).[jt]s?(x)"]
};

If the error started appearing after updating dependencies, a specific package may be causing the issue. Check the release notes for any breaking changes in the testing libraries or related dependencies. You can try updating the testing framework to the latest version, or if the problem persists, consider rolling back to a previous working version of the dependencies.

npm install jest@previous_version

After rolling back, re-run your tests to see if the issue is resolved.
