preset: recommended

Warns when a test group does not have any test cases.

Empty test groups are either the result of unfinished refactoring or added by mistake.

⚙️ Config​

Set include-methods (default is empty) to treat additional method invocations as test cases.

Example​

❌ Bad:

group('some group', () {
  // LINT: This test group does not contain any test cases.
  group('inner group', () {});
});

group('some group', () {
  // LINT: This test group does not contain any test cases.
  group('inner group', () {
    setUp({
      ...
    });
  });
});

✅ Good:

group('some group', () {
  group('inner group', () { // Correct, has a test case
    test('...', {
      ...
    });
  });
});

group('some group', () {
  group('inner group', () { // Correct, has a test case
    setUp({
      ...
    });

    test('...', {
      ...
    });
  });
});
