How can you make sure that an app does exactly what it should do without any weird unexpected surprises? Well, you test it, of course. You could test everything manually by launching the app, using it, and trying your best to make the app blow up with errors. Or you can write a bunch of automated tests, which is arguably a more time-efficient and thorough way to test your apps. Let’s take a look at unit, widget, and integration tests.

After so so long, there's finally smile on my face.
That's what I like to hear!
Bruh
Did you eat a beef steak?
@@reiniergarcia good one 🤣🤣
This is really great, advanced tutorials like this are not usually covered, thank you a lot
You're welcome!
Commenting before seeing the video, bcz you just going to save my life, Need the testing video on flutter desperately. I follow your channel and watch you videos and before seeing the video i just say it will be amazing. Thanks alot 👍👍👍
🙏
Thanks a lot for this video. I made it a good refresher in preparation to study the next part you made. I learned unit testing and TDD through your other series. I'd have too say this is more succinct and your explanations have gone better over time! Keep up the good work!
Reso, you are the best! Its a privilege to learn so much from you! Thanks a lot :)
I recently realized the importance of testing. however, there weren't well-organized advanced Flutter tutorials. I finally found it!
Thanks for the video!
Lots of appreciation for this 💕😍
I've been waiting for it. Really thank you.
Wonderful tutorial as always. Thanks for your efforts.
Love how you handle the await for future at the end. Never knew there is a way to both wait and not wait at the same time. Thanks for the tips!
Finally, you are back🎉🎉🎉🎊
After so long. Nice to see you again.
really appreciated how detailed you explained the app and its functionality as well as how to test. Others just assume you know half of the stuff (which is mostly not the case)
Thanks to you that using Flutter more efficiently, please upload the tutorial more often.
Really amazing to watch best youtube channel for flutter tutorials.. No words can reward your work 💙
The only one 1 hour educational video that I don't make me bored at the middle.
Thanks for the explanations, waiting for part2
I wish you could explain testing with getIt and especially injectable and mock classes
Thank you so much for this awesome content. Keep doing this good work 🎉
welcome back, best wishes. BEST DEVELOPER EVER
fantastic video! Nice dive into flutter and TDD. thks a lot for sharing! Highly appreciated!
Great stuff as usual 👍🏾
Thanks, man, you are an awesome teacher and developer!
Thanks for these tutorials 🎉 keep up the good work 👍
Welcome back 🔥🧡♥️
Once again for an amazing tutorial, keep it up you are doing an awesome job I can’t wait for part two!
Can you tell us how you structure you study when learning something new and where you find the resources e.g. books, documentation, tutorials.
Also do you have a must read list of books?
Thank you!
Welcome back 😍😍😍😍😍😍
You made it less boring than I expected🤩 Thank you very much 🙏
GREAT TUTORIAL! ONE OF THE BEST ON UNIT TESTING!
I can't wait for part 2 👍
thank you for this class!! 💙
Welcome back Reso
Awesome, thank you so much very clear explanation! 🙂
Your Video helped me to learn the testing.
welcome back 🔥🔥🔥
Liked it before watching because I trust it's actually an asset, please continue with testing tutorial because there a only few tutorials on testing in flutter
your explanation is easy to understand. thank you
Can't wait till the nexr part ^_^ thanks for your great help
Great vid! Waiting part 2..
Thank you so much for this.
Thanks for sharing bro, this really help me out.
Reso's back!
thank you so much reso coder🤝👏👏👏👏💛💛💛
Great work & effort Thanks for sharing Knowledge !!
Welcome back 🔥👍
Thank you very much for this good tutorial
I've been wanting for an updated video on test❤😅
Great video, thanks
amazing video, i was having hard time with your bloc TDD courses. I am very familiar with provider , this is very helpful for learning testing.
long time no see
Thanks so much!
Thanks a lot ❤
After two years of working as a part-time junior Flutter developer in my university student life, I've used lots of Flutter widgets, state managements, etc. But I don't feel like I'm improving much. Now, this tutorial would be the first step to approach senior level. Thanks a lot man!
I'm going into the university this year and that's my plan....to get some flutter side jobs / work on my personal apps. Did you get hired by companies or you worked as a freelancer?. Thanks
@@daumienebi Both bro! I'm now a university dropout. I'm working as a full-time senior flutter developer and also working as a freelancer in my free time.
Hello. I'm enjoying so far this video about testing. I have a question : which Visual Code plugins are you using to generate automatically code snippets for Tests (t-scaffolding, aaaT) ?
Reso is back
Welcome back 😉
welcome back =)
Thanks for the video :D
Can we use equatable in article class?
great tutorial
Thanks alot
Resooo we missed you 😍🎉🎉🎉
very good tutorial keep going
great job keep going
thank you so much
just beautiful
I actually use widget tests to test a small group of widgets for instance I have a calendar and a switch that changes the calendar from week view to month view with a shared state, this is normally where you'll find bugs rather than testing a single widget, to be clear I still test single widgets but small groups of widgets give us much better coverage and still get the speed of widget testing
Like before I watch
😊
Thank you Reso for your very nice video! I am a fan of TDD and trying to find the effective/resonable way to use it on my daily project
I got one question:
At the end of the video, you put the function notifyListeners() in getArticles() but it is not following the TDD flow since it is "redundance" for this specific test case. Do you agree?
Which test case we should write which will need this notifyListeners() called?
thanks,
Great it is being long time
Thanks for the tutorial man, I love your Vs Code config, can you share it plz!
Thanks a lot , boom .
please show how to correctly create folder by layer feature structure in flutter
hopefully you do this for your firebase DDD course
I respect your creativity. Everything is clear and understandable. I would really like a new playlist about blocks (ddd course)
Please don't ignore your followers.
Matt is Bacc !!!!!
I think code duplication is fine inside tests, as each unit test is expected to be optimised for readabiliy over DRYness
love u
Let's Go.
You mentioned that dependencies should be injected through constructor rather than hardcoding in the field declaration because that makes app more testable, but what if I have many chained dependencies? I will need to declarate all in the constructor every time. For example PersonProvider(PersonService(PersonDao(Dio("url"))))) is this correct or i there is a way to auto inject dependencies with container like on SpringBoot?
Can we mock the Article call using mocktail and use MockArticle instead of creating three different objects of Article class?
Very good toturial , #flutter_test , why you didn't use #mockito instead of #cocktail like your ttd clean architecture toturial
What happened to your website ?
Really good tutorial, keep going, but What's the theme of vscode.
what happened to your website? it's been offline for couple of days
Why you have used mocktail istead of mockito? is there a specific reason?
can anyone tell me the name of the vs code extention that displays those "----" dashes to indicate blocks of code?
Your website is offline, this was fix!!
what about stream rather than the future??
Great video, thanks. I think it's easier to put the `when` in `arrangeNewsServiceReturns3Articles` into a `setUp` in the group. So you don't have to call it, because `setUp` get called automatically, right?
No because in a third test you may don't want the same articles to be arranged
Make videos on bloc 8.0
I wondering why your website cannot be accessed?
I can't stand provider but I have used it
What happens to your website Mat?
its been over 1 year no any new video from sir Reso Coder. Are you Okay sir?
Make real-world examples video with mockito.
I'd still use mocktail though.
when is part 2 going to be out?
Saturday
Dude 😬 Make Tutorial with Auth0 implementation I Saw Some Article it's been outdated
Will Do something with that beard - I can't concentrate on the training 😂

I haven´t been creating apps for two decades,more or less,I´m PL/SQL programmer.But unit tests seems to be a really stupid Idea(change my mind),probably not useless,I mean for devices that work withouth human interaction like a mixer or a microwave woven.But E2E testing tests both the whole application and the code,they can be written by a QA and run totally isoalted from the system.At least in Brazil QA´s are less expensive than programmers.Unit tests does not seem so "agile",the concept of TDD is even worse itself.Do unit tests increase the size of the applicattion that I will distribute in the Android store,or they´re tree shaked out at least.I think they really slow down programming for what they do,as I said I´m not against testing ,i just think the testing budget should bne directioned for things like E2E,smoke,Happy path and gorila testing,wich are probably more effective and easy to automate.In 2022 Several big companies in Brazil had problems in production even havin teh so called 100% code coverage,from Banks to big E-Commerce stores.
