示例1: it
it('should remove a listener from the obs when unsubscribe is called', () => {
var o:any = new Observable<void>();
var generator:IGenerator<void> = {};
o.subscribe({});
var s:ISubscription = o.subscribe(generator);
expect(o._listeners.length).toBe(2);
expect(s.unsubscribe).toBeDefined();
s.unsubscribe();
expect(o._listeners.length).toBe(1);
});示例2: expectNotCalledAfterUnsubscribe
function expectNotCalledAfterUnsubscribe(operation:string) {
var count:number = 0;
var o:any = new Observable<void>();
var generator:any = {};
generator[operation] = (value?:void):any => count++;
var subscription:ISubscription = o.subscribe(generator);
o[operation]();
expect(count).toBe(1);
subscription.unsubscribe();
o[operation]();
expect(count).toBe(1);
}示例3: expectUnsubscribeOnDoneTrue
function expectUnsubscribeOnDoneTrue(operation:string) {
var o:any = new Observable<void>();
var generator:any = {};
generator[operation] = (value?:void):any => {
return {
done: true
};
};
o.subscribe(generator);
expect(o._listeners.length).toBe(1);
o[operation]();
expect(o._listeners.length).toBe(0);
}示例4: expectThrowOnCallbackThrow
function expectThrowOnCallbackThrow(operation:string) {
var called:boolean = false;
var o:any = new Observable<void>();
var e = new Error('Test Error');
var generator:any = {
throw: (error:string) => {
expect(error).toBe(e);
called = true;
}
};
generator[operation] = (value?:any):any => {
throw e;
};
o.subscribe(generator);
o[operation]();
expect(called).toBe(operation !== 'throw');
}示例5: expectNoThrowOnMissing
function expectNoThrowOnMissing(operation:string) {
var o:any = new Observable();
var count = 0;
if (operation !== 'throw') {
o.subscribe({
throw: (e:any) => count++
});
o[operation]();
expect(count).toBe(0);
}
else {
o.subscribe({});
