Warns when a test is invoked within another test invocation.

Such invocations will not be properly called by the testing framework and should be moved out.

Example

❌ Bad:

void main() {
  test('some test', () {
    // LINT: Avoid declaring tests or test groups inside other tests.
    //  Try moving this test out.
    test('some other test', () {
      final array = [1, 2, 3];
      expect(array, hasLength(1));
    });
  });
}

✅ Good:

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

  test('some other test', () {
    final array = [1, 2, 3];
    expect(array, hasLength(1));
  });
}
