[Feature] new function emitErrorFrom
It would be great to have an analogy to chai's built in throw:
// normal chai
expect(() => throw new Error('foo')).to.throw(Error, /foo/);
// eventemitter
expect(() => ee.emit('error', new Error('foo')).to.emitErrorFrom(ee, Error, /foo/);Would you be open to a PR?
Thanks!
TypeScript declaration
Hi, is this a good TS for your library?
declare module 'chai-eventemitter' {
function chaiEventEmitter(chai: any, utils: any): void;
namespace chaiEventEmitter {}
export = chaiEventEmitter;
}
declare module Chai {
interface Assertion {
emitFrom(ee: NodeJS.EventEmitter, event: string, ...args: any[]): Assertion;
}
}
