Cucumber Expressions - a simpler alternative to Regular Expressions

import assert from 'assert'

// A better assert.error that allows an exact error message
export default (fn: () => any, message: string) => {
  const regexp = new RegExp(message.replace(/[-[\]/{}()*+?.\\^$|]/g, '\\$&'))
  assert.throws(fn, regexp)
}
