`lowercase-name` rule `ignoreTopLevelTest` option

[overlookmotel]

To complement the ignoreTopLevelDescribe option added in #611, would it be possible to also have an ignoreTopLevelTest option?

I'd envisage it affecting both it and test - I doubt many people use both it and test in the same file, so it seems excessive to have separate ignoreTopLevelTest and ignoreTopLevelIt options.

An additional option ignoreTopLevel could also set both ignoreTopLevelDescribe and ignoreTopLevelTest.

Does this sound like a feature you'd accept? If so, I'd be happy to do a PR based on #611.

I don't feel like this makes sense, as the whole idea behind lowercase-name is about encouraging sentences that make grammatical sense; the reason we have ignoreTopLevelDescribe is because describe blocks "describe" things, and things like classes & react components start with a capital letter.

However, test & it are the start of a sentence, and so there's no common grammatical correct sentence that has the second word starting with a capital, except maybe test('MyClass to ensure it does the thing'), which I feel would be better wrapped in a describe anyway.

I guess it depends on how you write you test "sentences". I typically test that a library's exports are exported as intended, with something like this:

import { MyClass } from 'my-library';

test( 'MyClass is a function', () => {
  expect( typeof MyClass ).toBe('function');
} );

Does that seem like a reasonable case to you?

That makes sense, but I'm still lukewarm on adding a new option for this as I feel it leads to adding more options that are starting to miss the point of the rule.

In your case, you can make lowercase-name happy by just starting with that:

import { MyClass } from 'my-library';

test( 'that MyClass is a function', () => {
  expect( typeof MyClass ).toBe('function');
} );

describe is considered an exception for this because it's a lot harder to come up with a good, grammatical correct title that is not long winded for wrapping things whose names are in PascelCase; i.e:

describe('MyClass', () => {
  describe('#myMethod', () => {
    it('returns the right value', () =>{
      // ...
    });
  });
});

In the above, there isn't really a nice way to structure the title to have a lowercase name that reads correctly and doesn't require using a different structure to other tests for things like functions:

• "[describe] that MyClass",
• "[describe] the class",
• "[describe] the methods in MyClass"

I'm going to close this off due to the reasons outlined in my previous comment.
