Current behavior

Keepalive interval is run inside Angular zone, which causes Testability to be unstable.

Expected behavior

Keepalive interval should not affect Testability state, i.e. run outside of Angular zone.

Minimal reproduction of the problem with instructions

1. Set interval: keepalive.inteval(1000)
2. Start keepalive: keepalive.start()
3. Check the Testability state: getAllAngularTestabilities()[0].isStable()
4. See that it is unstable, i.e. false

What is the motivation / use case for changing the behavior?

To let the e2e tests pass in applications that use keepalive.

Please tell us about your environment:

Windows 7, IntelliJ, npm, Angular dev server

• @ng-idle version: 2.x

2.0.0-beta.15 & 6.0.0-beta.3

• Angular version: 2.x

5.2.11 & 6.1.2

• Browser: [all | Chrome XX | Firefox XX | IE XX | Safari XX | Mobile Chrome XX | Android X.X Web Browser | iOS XX Safari | iOS XX UIWebView | iOS XX WKWebView ]

all

• Language: [all | TypeScript X.X | ES6/7 | ES5]
  all
• Node: node --version =
  8.11.3

Suggested solution:
Keepalive interval function should be run outside of Angular zone, while onPing emission should run inside the Angular zone.

I can issue a PR if needed.

Do I understand correctly that no one can use protractor for testing his application once this package is used? Is there any workaround?

[just-jeb]

There is actually. If you run keepalive.interval() outside of Angular zone this will work. Worked for me.
But I still think this behavior should come out of the box with this package.

Thanks!! It would be great if you made a pull request, then we can source that one directly.

Will do in the nearest future.

Whoops, this PR was merged and I think has been in the codebase for a while now. It's definitely in the 8.0.0 beta builds.
