Provide testing module for store-log-monitor

[wesleycho]

One thing we have come upon at work is that if we use the store log monitor, when one wants to test that component, one must provide a component with the selector ngrx-store-log-monitor, which interferes with tslint if you add codelyzer and use component-selector-prefix.

This library should provide a mechanism for this situation to provide a mock component so that Angular doesn't throw when trying to compile a component in the template that it doesn't recognize.

Have you tried using the NO_ERRORS_SCHEMA in your test module?

[wesleycho]

How does one use it?

[brandonroberts]

You add it to the schemas array in your testing module.

import {NO_ERRORS_SCHEMA} from '@angular/core';

describe('Component', () => {
  beforeEach(() => {
    TestBed.configureTestingModule({
      declarations: [ Component ], // declare the test component
      schemas: [ NO_ERRORS_SCHEMA ] // ignores unknown elements
    });

    //...

  });
});

Oh interesting, thanks!

I wish this was better documented on the Angular side :( .

There is a section in the newly published testing chapter https://angular.io/docs/ts/latest/guide/testing.html#!#shallow-component-test

When I did a Google search, I first landed on this page & found the original PR implementing it, but neither really gives a clear indication of its usage.

Maybe I need to change my approach with how I search for ng2 stuff, but that's a personal problem.
