How do test code using inject()

[@PatriciaMolnar-b2n]

Thank you for sharing your knowledge!

You're very welcome.

Interesting. I’ve been using the parameter-declarator approach for years already. I was aware of the inject function and use that approach for Testing. Now finally I understand the background of these implementations after watching your video. Thank you for providing your the video.

You are very welcome. It seems like that the explanation at the very beginning is even more valuable than the acutal testing :D

[@vutruong4164]

indeed I find the technical background of the inject function very rewarding to know, since it is what I would need to convince my teammates to choose 1 approach over the other. You are killing it with this testing series. A lot of new stuff come out for Angular, but I believe the testing documentation has not caught up fast enough.

Thanks a lot, I was hoping that my explanation at the very beginning is of help. Have these discussions about inject all the time ;)

great video! I wish I knew about it earlier, I needed like days to find out how to test inject() in functional resolvers...

[@RainerHahnekamp]

Thanks, yeah, sometimes these things are easier than it seems :)

Another excellent video on testing

Thanks very much Paul. Next one will come out tomorrow!

Thanks for the video Rainer, One question on this is if I use the DI function imported in some service/component and try to mock the function in the unit test spec it still gives me the ng0203 error. Try to run in the runIninjectioncontext() still showing the inject() error for ng0203.

Hey, what exactly do you try to mock? Do you maybe have a code example?
