#19 - Dart Testing Explained - Unit, Integration, E2E and why you should aim for 100% code coverage

Hi there!
In this video I'll show you why you should definitely spend the extra time writing tests for your entire app. Using print statements inside the main file to check if the app is working or not is a really bad practice and you should change it. The soon, the better. I have prepared you a really nice package example that I'm going to entirely test as well as showing you all of the particularities of every type of tests you'll encounter. Enjoy!

You have never failed us...

Thank you so much, bruno! ✨

Very important Topic. Doesn't have many tutorials about

[@ankitsagar7431]

I think more in-depth video is needed on tests. But really your all videos are really in-depth really awesome work. Thank you WCKD.

[@Flutterly]

Yes, I agree, but I will cover them up in the flutter section

[@ankitsagar7431]

​@@Flutterly Ohh! there's an upcoming flutter session too. That's great news!

Hitting the like button since #1. Thanks for the great Video! QUESTION. Do we test the functionality of streams(listeners, subscriptions etc.) the same way or with Widget testing? Or is there another approach.

[@AyushPanditofficial]

Nice sir really wating for next part

[@Flutterly]

It will come soon 🔜!

[@radurot7673]

Great content. The only thing that it lacks for me in this series is the absence of a github repo with the code as a starting point to play around. That would help more to follow your explanations

[@Flutterly]

Hello, Radu! First and foremost thank you so much for your valuable feedback! Yeah, I am aware of this issue, when I was first designing the course, I wanted the entire series to be follower along, so that viewers can implement the entire code by their own. So this is why I went with this structure without a github repository. Therefore, unfortunately the majority of the projects I built in these early tutorials got deleted from my computer, I wish I could upload them now, but I'd have to write them again and again for every tutorial, and that's not a viable option. I'll try and improve myself over the next series and videos and I admit it was a mistake not posting the code on github. Thank you again,

@@Flutterly I really appreciate you took time to respond. It's not at all a major issue. The content is great Looking forward for blocFromHeroToWizard series

[@Flutterly]

Haha, after I wrote you the reply, I went into my ssd drive and frankly I have found some of the packages I created for this Dart series, will let you know if I manage to upload at least what I still have on the block! Yeah, I'll continue that series soon, I have a couple of more advanced concepts to be taken care of inside this Dart course.

[@radurot7673]

@@Flutterly great news, happy to hear that :D

[@Flutterly]

Just double checked and it seems like I lost the project in which I discussed Dart Classes, frankly one of the most important tutorials from this series 😔

[@marcrenken1169]

Hey :) Is there any way to run these tests for dartjs as well? I would like to use these tests to test if my code works crossplatform. Thanks again for the great course - it helped me a lot.

[@islomkhujaakhrorov6668]

Cool video

[@Flutterly]

Thanks man! ✨

[@davidowens9597]

Do we really need to copy code into the "test" folder? That doesn't sound right. Can't we just import whatever library we want to test?

[@Flutterly]

I didn't say that you need to copy code into the test folder. I said that every library/file should have its own test into the test folder, therefore the test folder should have the same structure as the lib folder. Of course, inside the test files you'd need to import the libraries you're going to test right from the lib folder by using the import package directive.

[@davidowens9597]

@@Flutterly I got confused by that part and re-watched it after I saw your reply. Thanks.
