ReactiveTest Class Methods

Rx.ReactiveTest.onCompleted(ticks)

# Ⓢ

Factory method for an OnCompleted notification record at a given time.

参数

1. ticks (Number): Recorded virtual time the OnCompleted notification occurs.

返回值

(Recorded): OnCompleted notification.

例

var onCompleted = Rx.ReactiveTest.onCompleted;

var scheduler = new Rx.TestScheduler();

var xs = scheduler.createHotObservable(
    onCompleted(260)
);

var res = scheduler.startWithCreate(function () {
    return xs.map(function (x) { return x; });
});

// Write custom assertion
collectionAssert(res, [
    onCompleted(260)
]);

Rx.ReactiveTest.onError(ticks, exception)

# Ⓢ

Factory method for an OnError notification record at a given time with a given error.

参数

1. ticks (Number): Recorded virtual time the OnError notification occurs.
2. exception (Error | Function): Recorded exception stored in the OnError notification or a predicate

返回值

(Recorded): Recorded OnError notification.

例

var ex = new Error('woops');

var onError = Rx.ReactiveTest.onError;

var scheduler = new Rx.TestScheduler();

var xs = scheduler.createHotObservable(
    onError(201, ex)
);

var res = scheduler.startWithCreate(function () {
    return xs.map(function (x) { return x; });
});

// Write custom assertion
collectionAssert(res, [

    // Using a predicate
    onError(201, function (e) { return e.message === 'woops'; })
]);

Rx.ReactiveTest.onNext(ticks, value)

# Ⓢ

Factory method for an OnNext notification record at a given time with a given error.

参数

1. ticks (Number): Recorded virtual time the OnNext notification occurs.
2. value (Any | Function): Recorded exception stored in the OnNext notification or a predicate

返回值

(Recorded): Recorded OnNext notification.

例

var ex = new Error('woops');

var onNext = Rx.ReactiveTest.onNext;

var scheduler = new Rx.TestScheduler();

var xs = scheduler.createHotObservable(
    onNext(201, 42)
);

var res = scheduler.startWithCreate(function () {
    return xs.map(function (x) { return x; });
});

// Write custom assertion
collectionAssert(res, [

    // Using a predicate
    onNext(201, function (x) { return x === 42; })
]);

ReactiveTest Class Fields

Rx.ReactiveTest.created

# Ⓢ

Default virtual time used for creation of observable sequences in unit tests. This has a value of 100.

例

var scheduler = new Rx.TestScheduler();

var xs = scheduler.createHotObservable(
    Rx.ReactiveTest.onNext(201, 42),
    Rx.ReactiveTest.onNext(202, 56),
    Rx.ReactiveTest.onCompleted(203)
);

var res = scheduler.startWithTiming(
    function () { return xs.map(funxtion (x) { return x; })},
    Rx.ReactiveTest.created,
    Rx.ReactiveTest.subscribed,
    Rx.ReactiveTest.disposed
);

Rx.ReactiveTest.disposed

# Ⓢ

Default virtual time used to dispose subscriptions in unit tests. This has a value of 1000.

例

var scheduler = new Rx.TestScheduler();

var xs = scheduler.createHotObservable(
    Rx.ReactiveTest.onNext(201, 42),
    Rx.ReactiveTest.onNext(202, 56),
    Rx.ReactiveTest.onCompleted(203)
);

var res = scheduler.startWithTiming(
    function () { return xs.map(funxtion (x) { return x; })},
    Rx.ReactiveTest.created,
    Rx.ReactiveTest.subscribed,
    Rx.ReactiveTest.disposed
);

Rx.ReactiveTest.subscribed

# Ⓢ

Default virtual time used to subscribe to observable sequences in unit tests. This has a value of 200.

例

var scheduler = new Rx.TestScheduler();

var xs = scheduler.createHotObservable(
    Rx.ReactiveTest.onNext(201, 42),
    Rx.ReactiveTest.onNext(202, 56),
    Rx.ReactiveTest.onCompleted(203)
);

var res = scheduler.startWithTiming(
    function () { return xs.map(funxtion (x) { return x; })},
    Rx.ReactiveTest.created,
    Rx.ReactiveTest.subscribed,
    Rx.ReactiveTest.disposed
);
