Rx-TestScheduler-Injector injects your Rx.TestScheduler into time related Rx.Observable operations using Jasmine spies.

You can use npm or Bower:

npm install rx-jasmine-testscheduler-injector --save-dev

bower install rxjs-testscheduler-injector --save-dev

To inject your test scheduler to all operators use:

// Do this when you use npm
const RxJsTestSchedulerInjector = require('rx-jasmine-testscheduler-injector');

// This then works for npm and Bower
RxJsTestSchedulerInjector.inject(yourTestScheduler);

With this you inject your scheduler to the following chainable operations:

• debounce
• throttle
• delay
• timeout
• sample

And also inject the test scheduler into these Rx.Observable operations:

• Rx.Observable.interval
• Rx.Observable.timer

This function returns an Object containing the created spies. If you want to access the spy for the debounce operator, use:

var rxjsSpies = RxJsTestSchedulerInjector.inject(yourTestScheduler);
var debounceSpy = rxjsSpies.debounce;
expect(debounceSpy).toHaveBeenCalledWith(200);

The inject() method also has the ability to exclude some methods when injecting the TestScheduler:

RxJsTestSchedulerInjector.inject(yourTestScheduler, ['debouce', 'inverval', 'delay']);

The exceptions always have to be passed as an array of method names (look for possible methods in the lists above).

Besides the inject method to inject to all operators there is the possibility to just inject to a single one using

RxJsTestSchedulerInjector.injectInto(operatorName, testScheduler);

with the name of the operator (as a String) and the test scheduler index.

This function returns the spy that injects the operator.
