QUESTION
I have a method to get product data from an API. I use Axios to call the API. Since the product data is independent of each other, I call all the APIs at once and use Promise.all
to wait for the calls to complete before proceeding. For example, consider a function (not enclosed in a function statement) with below lines.
ANSWER
Answered 2022-Jan-06 at 03:05Since you are modifying the same object reference(mockedSuccessResponse.data
), subsequent changes will overwrite the previous ones. This means the mocked object(sku2
) for the url
ends with /SKU-2
will override the mockedSuccessResponse.data
. When you call axios.get()
in promise.all
, both of them resolved the sku2
mock data.
Solution: Create different mock objects for different conditional branches.
E.g.
index.ts

QUESTION
I have an Angular project using Firebase for authentication. In order to authenticate to our server, we need the JWT from Firebase. The project is using Angular Fire to accomplish this.
We have an HTTP interceptor that intercepts any requests to the server, and adds the required Authorization header. The interceptor seems to work perfectly, but we would like to unit test it as well.
Our AuthService is responsible for delegating actions to Firebase. The getCurrentUserToken
method retrieves the JWT as a promise, as Angular Fire will refresh the JWT if needed.
This complicates the interceptor slightly, since we need to asynchronously get the token and wrap it into the Observable from the request.
token-interceptor.ts ...ANSWER
Answered 2021-Dec-17 at 16:32I think the issue is in the interceptor because we may be not waiting for the async
task of const token = await this.authService.getCurrentUserToken();
to complete before going on to the assertion.
Add a console.log like this in the interceptor:

I have a function that when calling it opens a modal from ngbModal, I have imported everything necessary and also created a mock of NgbModalRef, but when I do the unit test I get this error "TypeError: Cannot set properties of undefined (setting 'object')".
I tried a solution on stackoverflow but it doesn't work completely, this is the source: Writing a unit test for ng-bootstrap modal (NgbModal) [Angular 6]
How can I fix that error in my test?
My function
...ANSWER
Answered 2021-Sep-29 at 07:53Since 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
QUESTION
I have the below http interceptor in my angular application and I would like to unit test the same using Jasmine. I googled some of them and tried but its not working as expected. Please find the below HttpInterceptorService.ts file code
...ANSWER
Answered 2021-Sep-09 at 13:00Remove HttpInterceptorService
from the providers because you are already providing it on the next line with { provide:HTTP_INTERCEPTOR, ...
. Try to follow this guide: https://alligator.io/angular/testing-http-interceptors/. It seems like you need to have a service that actually makes API calls. Try to follow this guide as well: https://www.mobiquity.com/insights/testing-angular-http-communication
I think to make an HTTP call, you can just do httpClient.get('www.google.com').subscribe()
and you shouldn't need an actual service (DataService
) like the first guide shows.
Edit:

QUESTION
I am trying to test statements after 1st await but it doesn't work. Debugger doesn't hit the next breakpoint
service.ts
...ANSWER
Answered 2021-Aug-11 at 10:35In order to proceed execution after await
your need to fulfill two things:
- resolve and complete Observable by simulating http request
- simulate the asynchronous passage of Promise
You already use tick()
that solves the second case but it does nothing without simulating http request.
Use TestRequest#flush method for that:

Answered 2021-Aug-09 at 17:49Resolution so to solve that, just check if the string your are trying to parse is empty/null or not. if is not empty/null you can parse that string.
