我有一个很大的问题,因为当我尝试测试包含多个承诺的选择主题功能时,我总是看到像
这样的错误当没有当前规范时使用'expect',这可能是因为异步测试超时
我尝试使用fakeAsync,但它会抛出
无法在假异步测试中制作XHR。
it('should set regular topic', async(inject([FirebaseRateService], (service: FirebaseRateService) => {
service.setTopicId("randomTopic 2");
service.getTopicStream()
.subscribe( (topicId:string) =>{
console.log(topicId);
expect(topicId).toBe("randomTopic 2");
})
})));
setTopicId( topic_id:string ){
if( !this.auth.check() )
this.auth.signAnonyous().then( () => this.selectTopic(topic_id));
else
this.selectTopic(topic_id);
}
private selectTopic( topic_id:string ){
selectTopic( this.db, topic_id )
.then(
() => {
this.topicId = topic_id;
this.topicStream.next(topic_id);
}
)
}
getTopicStream(){
if(this.topicId)
return this.topicStream.startWith(this.topicId);
return this.topicStream.asObservable();
}
