The solution will be to flush active timeouts (as @MBielski mentioned it in comments), but original flush method itself is available only in anuglar-mocks. To use angular-mocks directly you will have to include it on the page as a <script> tag and also you'll have to deal with all overrides it creates, it produces a lot of side effects. I was able to re-create flush without using angular-mocks by listening to any timeouts that get created and then reseting them on demand.
For example, if you have a timeout in your Angular app:
$timeout(function () {
alert('Hello World');
}, 10000); // say hello in 10 sec
The test will look like:
it('should reset timeouts', function () {
browser.addMockModule('e2eFlushTimeouts', function () {
angular
.module('e2eFlushTimeouts', [])
.run(function ($browser) {
// store all created timeouts
var timeouts = [];
// listen to all timeouts created by overriding
// a method responsible for that
var originalDefer = $browser.defer;
$browser.defer = function (fn, delay) {
// originally it returns timeout id
var timeoutId = originalDefer.apply($browser, arguments);
// store it to be able to remove it later
timeouts.push({ id: timeoutId, delay: delay });
// preserve original behavior
return timeoutId;
};
// compatibility with original method
$browser.defer.cancel = originalDefer.cancel;
// create a global method to flush timeouts greater than @delay
// call it using browser.executeScript()
window.e2eFlushTimeouts = function (delay) {
timeouts.forEach(function (timeout) {
if (timeout.delay >= delay) {
$browser.defer.cancel(timeout.id);
}
});
};
});
});
browser.get('example.com');
// do test stuff
browser.executeScript(function () {
// flush everything that has a delay more that 6 sec
window.e2eFlushTimeouts(6000);
});
expect(something).toBe(true);
});
It's kinda experimental, I am not sure if it will work for your case. This code can also be simplified by moving browser.addMockModule to a separate node.js module. Also there may be problems if you'd want to remove short timeouts (like 100ms), it can cancel currently running Angular processes, therefore the test will break.
