I'm gonna need to see this video more than a couple of times... Testing is mindblowing, thank you so much for explaining them! One question Simon, is it necessary to keep track of the subscription when testing observables and unsubscribe afterEach test block?

[@galaxies_dev]

Not 100% sure if it's necessary but can't hurt to clean up :D

[@cinematicvideosbyrumel7216]

How do you test it when you use functions like adding a doc to/ reading a doc from a firestore collection in the service.ts? One good video tutorial would be a good resource for us since we don't find enough resources regarding testing firestore related functions.

SImon, how would you inject the Google Place Module into a unit test?

[@Eyezbergslim]

Great tutorial as usual, but I"m having issues with a unit test that requires me mocking the GooglePlace Module. Do you have an example of how to do that?

[@alanbique2548]

one more top quality video!! Thankss!!

[@galaxies_dev]

Thank you!

[@w3tweaks408]

can I get jest unit test case for ionic capacitor plugin?

[@TheLukedb]

Can you make a new video with Jest since Angular is moving away from Karma?

[@mostafaosman1437]

Thank you for this

[@galaxies_dev]

No problem 😊

[@vladimirkolesnikov8672]

Thanks a lot! What about unit testing functionality connected with Capacitor's native features?

[@galaxies_dev]

In those cases you would most likely create a Mock object of the Capacitor class since you can't really trigger a native plugin within a test!

Hi Simon I am trying to integrate paid api for voice and video calling in ionic Cordova app but unable to implement it. So will you please guide me for that how can I implement this. Please provide me a solution for that as soon as possible.

[@mohammadaamir7741]

Tried walking through this tutorial and got to about 4:16 when my npm Test threw the following error: "Error: src/app/services/data.service.ts:12:31 - error TS2345: Argument of type 'string | null' is not assignable to parameter of type 'string'. Type 'null' is not assignable to type 'string'. 12 const result = JSON.parse(localStorage.getItem('todos'));" Not sure if there's a newer version of this video tutorial with updated code or if I'm doing something wrong on my end.

[@Gabriel-pe6oi]

do this: getTodos(): any[] { const data = localStorage.getItem('todos'); const result = data ? JSON.parse(data) : []; return result; }

Hey Simon can please make a video on auto verification of phone number using ionic capacitor

[@carlosmontiel7078]

Can you make a vide on how to do ionic build android/ios and then install it ? I was wondering the way you can sign apps with ionic.

[@galaxies_dev]

Sounds good Carlos, sure!
