warning

🛠

preset: recommended

Warns when a test case has multiple test assertions with the same expression and expected value.

Example

❌ Bad:

void withEmpty() {
  final array = [1, 2, 3];

  expect(array, isEmpty);
  expect(array, isEmpty); // LINT
}

✅ Good:

void withEmpty() {
  final array = [1, 2, 3];

  expect(array, isEmpty);
  expect(array, contains(1));
}
