assertRejects<E extends Error = Error>(

fn: () => Promise<unknown>,

ErrorClass?: new (...args: any[]) => E,

msgIncludes?: string,

msg?: string,

): Promise<void>

Executes a function which returns a promise, expecting it to throw or reject. If it does not, then it throws. An error class and a string that should be included in the error message can also be asserted. Or you can pass a callback which will be passed the error, usually to apply some custom assertions on it.
