问在Promise解析之前，Mocha测试失败

EN

it('Test', async () => {
    this.party = new Party('example_id');
    await this.party.startWithPlaylist('3e8JNsQmYEXtfV7K1M0pAb');
    assert.isTrue(this.party.getStreamingProvider().getAuth().getToken() !== undefined);
})

startWithPlaylist(id) {
    return new Promise(async (resolve, reject) => {
        assert.ok(id !== undefined);
        await this.start();
        let playlist = await this.songInfoProvider.getPlaylist(id);
        resolve();
    });
}

Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.
