prefer-unique-test-names

added in: 1.11.0
warning
⚙️
preset: recommended

Warns when the test name is not unique within the same test suite.

A test with a non-unique name will be skipped when running from the IDE. Same goes for tests with non-unique names inside a for loop.

⚙️ Config​

Set include-methods (default is none) to treat additional method invocations as test cases.

Example​

❌ Bad:

void main() {
  test('some test', () {});
  test('some test', () {}); // LINT

  for (final item in [1, 2, 3])
    test('broken test', () {}); // LINT
}

✅ Good:

void main() {
  test('some test', () {});

  group('some group', () {
    test('some test', () {});
  });

  for (final item in [1, 2, 3])
    test('good test $item', () {});
}
