Bug description

The react-test-renderer library provides several utils which match the find* query pattern: findByType, findByProps, findAll, findAllByType, findAllByProps.

These methods are provided from a react-test-renderer instance, or any React Native Testing Library query. They should be ignored, so they are not treated as Testing Library queries (since they actually aren’t).

This should apply to all rules, so it must be implemented in the isQuery internal helper. This function should ignore the queries listed before if they were imported from react-test-renderer or @testing-library/react-native. Checking the imports from the latter it’s important since react-native-testing-library queries return nodes with the mentioned utils, so it’s possible to do something like getByRole('modal').findByProps('bar'), hence ignoring react-test-renderer utils if coming from @testing-library/react-native

Steps to reproduce

This example extracted from React docs to cover the react-test-renderer import:

import TestRenderer from 'react-test-renderer';

function MyComponent() {
  return (
    <div>
      <SubComponent foo="bar" />
      <p className="my">Hello</p>
    </div>
  )
}

function SubComponent() {
  return (
    <p className="sub">Sub</p>
  );
}

const testRenderer = TestRenderer.create(<MyComponent />);
const testInstance = testRenderer.root;

expect(testInstance.findByType(SubComponent).props.foo).toBe('bar');
expect(testInstance.findByProps({className: "sub"}).children).toEqual(['Sub']);

Example to cover the @testing-library/react-native import:

import { render } from '@testing-library/react-native';

test('some test case', () => {
  render(<SomeComponent />);
  const falsePositive = screen.getByText('foo').findByProps({ testID: 'bar' })
})

It would be interesting to check the test cases added in this PR.

Error output/screenshots

findByType, findByProps, and other react-test-renderer utils are reported by the plugin (e.g., await-async-queries complains about they must be awaited).

Rule(s) affected

All rules reporting on queries are affected, but await-async-queries is the most obvious one.

Anything else?

This was originated by #671 and #703

Just making a note to whomever will fix this bug, there’s another issue related to react-test-renderer: #494 and it will be handy to re-use the new helper function that detects imports from react-test-renderer in fixes to both issues 📝

[Belco90]

I’ve closed my original PR #709 since such workaround could lead to other problems. I don’t have enough time to implement the ideal fix, but I’ve updated the issue again with more details about how it should be done.

As a temporary workaround, @testing-library/react-native users can avoid the false positives by switching off the custom-queries reporting entirely.

I’ll create a PR to mention this in the Troubleshooting section.
