expect(...).rejects.toEqual() crashes test runner when assertion fails

[harukogaki]

🐛 Bug Report

I am attempting to write a test that asserts that an error thrown conforms to a particular format. Ive noticed that the .rejects.toEquals approach works assuming the assertions pulls through. However, if it fails the test runner crashes. Ive tried putting try catch blocks over the assertion but to no avail. I also did some light reading into the issue and found that this has been a known issue so I'm looking for potential mitigation strategies or guidance.

To Reproduce

const promiseThatRejects = new Promise((resolve,reject) => reject("Error"))
expect(promiseThatRejects).rejects.toEqual("Error2")

Expected behavior

the test runner doesn't crash

Actual behavior

/app/node_modules/react-scripts/scripts/test.js:20
  throw err;
  ^

Error: expect(received).toEqual(expected)

Expected value to equal:
  "Error2"
Received:
  "Error"

using reject (or resolves) makes the matcher async, so you need to wait for the promise. Either by await or returning it.
