registerFallbackValue seems to be not working as intended about mocktail HOT 5 CLOSED

Ok I found the problem within a minute after creating the issue. setUp is calling before every test not group. So stubbing should be done inside a test.

from mocktail.

@felangel The example provided by @Amir-P above shows the issue. This sequence

...
group('description', () {
    MockOtherTestClass otherTestClass = MockOtherTestClass();
    when(() => otherTestClass.test(any())).thenReturn('expected');
    test('test', () {
...

will continue to tell you to add a setup that calls registerFallbackValue even after you add the recommended code.

The only way to make it work is to move the when into the test

...
group('description', () {
    MockOtherTestClass otherTestClass = MockOtherTestClass();
    test('test', () {
        when(() => otherTestClass.test(any())).thenReturn('expected');
...

@felangel, we encountered this too (and took longer than a minute to figure it out). It would be useful if there were a different message printed for when clauses using any in the group that explicitly mentions that any has to be in a test.

BTW, thanks for this package. The new Mockito generator didn't understand many things (covariant parameters, parameters on toString, even Iterable). Except for this issue (which we encountered on our first conversion of any) the migration to Mocktail was straightforward.

Hi @rich-j 👋
Thanks for the positive feedback! I really appreciate it 🙏

Are you able to provide a simple reproduction sample of the problem you were facing? I'm happy to improve the error messaging, thanks! 👍

Got it, thanks for clarifying 👍

I've created #41 to track this improvement 😄
