Doesn't work with jest

I keep hitting these errors when rendering a component

I’ve seen multiple issues where people wanted Jest support and it was added… But from what it looks like it doesn’t work? jest-preset-angular inlines all the HTML, so there’s really no reason for it to be doing a http request to get the template.

In the 2 diff apps that I’m using jest with angular I use this builder for the tests:

You didn’t mention whether you are using this already or not but I hope this helps.

Shallow render is mostly a wrapper around TestBed. The Http request is made to fetch the HTML template during the TestBed.compileComponents call. I believe it only makes an http request when the template is in a separate file than the component class. Could you try writing an equivalent test with TestBed for the same component? My guess is that the TestBed test would fail in the same manner when you called compile components.

Sorry for the lack of formatting, I’m on a phone at the moment.

@getsaf actually it was a problem with me not including html as a transform matcher for ts-jest
