jest-marbles | Helpers library for marbles testing with Jest | Reactive Programming library

I want to group all related dependencies in one merge request (MR), as the examples below:

In one MR (all starting @angular/ except @angular/cli):

I'm using ngrx/store for managing the state of my app.

I'm using jest & jest-marbles for testing the app. But while doing testing I'm not being able to run the test suite properly.

I'm getting the following error while running tests with ngrx/store/testing.

How can I rectify this error?

I've inspected the path

[Using angular and ngrx.]

I'm using jest and jest-marbles for testing a service. I'm using the store inside this service. The service depends on a boolean value from the store (isDisplayItems).

If it is true, only then the other functions inside the service works.

So I need to mock a value so that I can make it working. It will be possible only if I can provide a fake value like this.

I've got an issue testing a failed action on my effects.

To give a bit of context here loadProducts effect is executed when the Load action is called. Inside the effect an HTTP request is performed, in case this request is executed successfully the LoadSuccess action is called, otherwise LoadFail is called. Code here bellow
