Angular component testing - Overcoming the hurdles

Your team’s sizable Angular apps are coming along well, but the voice in the back of your head is shouting: we need unit tests. But there are hurdles: you want to test components, but how do you set up the necessary dependency injection and get the HTML template to work in the test?

In this event, you will learn to overcome the hurdles:

Get tests wired up correctly at the start.

See a productivity payoff from well-planned dependency injection in tests.

Simplify and speed up your tests by avoiding the hurdles entirely.

Finished my basic api/angualr site and now have to test. Literally can't get one test to pass anything....so hoping the video helps

[edvinbeqari]

How do you configure Karma or Jasmine to see the html within the Jasmine interface?

[vackoo]

Thanks for the insightful talk, but making the tests lightweight comes at the cost of not testing the template section of the component right? Is that the right approach when it comes to unit testing of components in angular?, Just asking because am fairly new to angular and would like to understand the tradeoffs one is making while writing unit tests

hii im getting error
Can't bind to 'ngForOf' since it isn't a known property of 'div'
1. If 'div' is an Angular component and it has the 'ngForOf' input, then verify that it is a part of an @NgModule where this component is declared.
