Topic: Testing Notifications with Jasmine

waffaru free asked 5 years ago


After importing and using ToastModule for Notifications, my tests no longer pass. This was expected behaviour. However, the error I'm getting is as follows:

Error: StaticInjectorError(DynamicTestModule)[ToastrService -> InjectionToken ToastConfig]: 
  StaticInjectorError(Platform: core)[ToastrService -> InjectionToken ToastConfig]: 
    NullInjectorError: No provider for InjectionToken ToastConfig!

I have no idea what I should try importing to solve the issue. Importing ToastModule.forRoot() doesn't seem to fix the issue and neither does importing separate services.

Can you please point me to the right direction on how to make it so my component test actually creates? Thanks.

This was a mistake on my part. I was using NGX's ToastrModule before moving to this one and had a service still importing it that was being used by this component. Removing the dependency fixed my issue.

use ToastrModule.forRoot() instead of ToastModule.forRoot()

Hey! The TS and HTML file in which I use toasts are completely fine and working. It's the tests I'm having issues with and setting up the Testbed for it.

Here's what the testbed looks like in my test file:

  beforeEach(async(() => {
      imports: [
        ReactiveFormsModule, FormsModule, InputsModule, WavesModule, TranslateModule,
        ToastModule.forRoot(), MDBBootstrapModulesPro, HttpClientModule, RouterTestingModule
      declarations: [
        (Bunch of unrelated declarations)
      providers: [{provide: FormBuilder, useValue: formBuilder}, PrincipalService, ToastService]

As for the .TS file that uses it, I just have a dependency-injected ToastService, and I use the service's error-method on a failed API call.

For the actual file I import ToastModule.forRoot() on a shared module and it works fine. But importing ToastModule.forRoot() on a testomodule doesn't seem to work.

Could you show the content of your module file and provide the html and ts code of the component in which you use toasts?
