Originally extracted from mocha
import {format} from 'assertion-error-formatter'

When an assertion message starts with "expected" it is lost because of the following lines in src/index.js
const match = message.match(/^([^:]+): expected/);
message = options.colorFns.errorMessage(match ? match[1] : message);Given the assertion error message is "expected something to happen"
expect failing tests to print AssertionError [ERR_ASSERTION]: expected something to happen
The failing test prints AssertionError [ERR_ASSERTION]
