Looks like the jest-circus test failed, it doesn't appear related to the readme, but I could be wrong. Please advise, thanks!

test-jest-circus is work incorrect sometimes 💃

@SSTPIERRE2 Thank you for contributing to Jest. To help interact on your contribution:

1. Can you say which version?
2. Can you give a few examples of confusing tests that motivate the sentence? The wording might need to become more specific for which type of expected argument in the assertion.

For example, toThrow assertion without argument works for values that are not instance of Error:

test('toThrow without expected value', () => {
  const received = () => {
    throw 13;
  };

  expect(received).toThrow();
  expect(received).not.toThrow();
});

expect(received).not.toThrow()

Thrown value: 13

This improvement in the report from #7621 in Jest 24.0.0 or later

P.S. Yes, ignore test-jest-circus failure on CI

When you edit Jest .md files, you can run locally yarn lint:md before you commit the change

Rebasing on master should fix CI, fwiw

From #8772 (comment), I don't think the docs change is correct, so closing.
