testbed | With this testbed, it is possible to run a full OSISM installation, the baseline of the Sovereign Cl | Continuous Deployment library

First off, the TestBed configuration is totally useless in your sample. Just delete it.

Your bug is because you are providing a mock return value for get but your method under test calls post. Because the default return value for spied methods is undefined it blows up on the .pipe() with that error.

You need to use TestBed.inject here:

In case someone else run into this issue, the problem was related to the eslint or tslint configuration for the test and it got fixed adding the swiper_angular to the compilerOptions > paths in the tsconfig.json (or the tsconfig.spec.json) file:

In your test setup you provide the following activated route:

Do you call subscriptionPackages in the ngOnInit or the constructor of the component?

If you're calling it in the ngOnInit, you need to mock the returnValue before the first fixture.detectChanges(). The first fixture.detectChanges() is when ngOnInit is called.

The issue here is, Angular lifecycle method will only be called when you call fixture.detectChanges() and you are initializing emp object inside ngOnInit(). So you can't access emp object properties before calling fixture.detectChanges()

Try below code (view-employee.component.spec.ts):

I had similar problem running all test at once. If run one by one then I don't see this error. So I added the following line of code at each test method end

Since angular uses typescript you need to mention the type of the variable that you're using, so wherever you are using arrow function specify the type of the object.

For example:In your ts file specify the type for result also for filter

This is not possible because azure subscription needs to be known at compilation time. You set your variable on run time.

Here an issue with similar case when it is explained:

run time variables aren't supported for service connection OR azure subscription. In your code sample, you are referring to AzureSubscription variable which will get initialized at the run time (but not at save time). Your syntax is correct but you need to set AzureSubscription variable as part of variables.

If you define your variables like:
