Flutter Unit Testing Tutorial For Beginners - Practical Guide
Рет қаралды 34,163
Күн бұрынLearn how to unit test your Flutter Apps. In this video, you'll understand what Unit Test is, why it's good to Unit Test and what non testable code is. Then, we will Unit Test a Counter app to understand Unit Test Basics. Moving on, we will Unit Test a class that has external dependency like HTTP Plugin to understand Mocking, Stubbing and need to do them. We will also learn about Dependency Injection.
Thinking of implementing Unit Tests & other tests in upcoming project videos, what do you think?

Nice video Rivaan, thanks. I can't get why the test passed after you removed the await keyword at 1:01:23. You said that if we await for the userRepository.getUser() function, it will actually throw an exception (and thus we need a try catch block), but isn't it what we want? Also, why does removing await work? Is it not throwing exception anymore? If it does, why don't we need a try catch block here? This part was not clear to me. Once again, thanks for this video.

I have doubt 1:05:15 Doubt is when we are fetching data from server then why we are using .thenAnswer . IF we don't have any usage of no dependency what server is returning to us then why we are fetching we can also simple write the Response part and use that why we are doing this headache job ? when we are returning the same response every time. Also when backend developer change something the the response then our test _ code not know that we think it is okay and deploy the app to play store . Also let suppose if server is giving the error 404 or some other exception then think every time our code is okay ? how so in this case we also need to depend on the manual testing do you agree with it ?

However, it's almost the same thing as Mocktail except it's got code generation so you dont have to write big lines like `class MockClient extends Mock implement Client{}`.

Hey Rivaan, when you decide to teach something. No matter how hard the concept is i know we will learn it so easy. I have some questions for you. 1- Could you please continue the design pattern series ? 2- Can you make video about folder Structures and architecture patterns like mvvm ? 3- Can you give us advices about how to learn concepts better without needing helps from others too much ? (maybe some books, reading documents tips or some trick that you use while you learning) Thanks for you hard works. I hope we can help you too later on. 🫡
@RivaanRanawat Жыл бұрын
Thanks for the kind words Semih! 1. Design Patterns series is definitely going to be continued. 2. I am planning to use either MVVM or Clean Architecture in the next project tutorial. I also have an Architecture Series in mind which covers things like MVC, MVVM, MVP, Clean architecture and so on. But it will only be out once I complete Design Patterns series. 3. Just think what you wanna learn and search about it online. There's obviously Flutter docs which helps. If you don't understand, keep going through several blogs until you understand. There's ChatGPT too now. It's not always accurate but it can help you in simplification of things. Suppose you read a blog and dont understand a certain part. You can ask ChatGPT about the same. Most of the books in Flutter are written for beginners and dont help after a certain point. Main point is to not give up to learn the topic you want to learn.
