Introduction4:43
Learn to apply test driven development with Flutter by building a small app using a fake HTTP server and mock API, exploring clean architecture, user endpoints, and Firebase testing.

Create user entity6:17
Understanding object compare in dart12:51
Discover how Dart differentiates referential and value equality, and learn to override the equality operator and hashCode to implement value-based comparisons using Equatable.
Install dartz package and understand Either type11:03
Learn to implement value equality with Equatable, define an authentication repository contract, and use the dartz Either type to model server failures in clean architecture.
Create failure and typedef11:08
Dart callable call function12:10
Done with domain layer usescases create user4:15
Domain layer usecases get_user4:53
About domain layers

Understanding testing7:59
Create test part 115:59
Create test and done with STUB part 27:58
Learn how to stub and hijack dependencies in tests for a Dart and Flutter clean architecture setup, using then, then answer, and right/left in an asynchronous create user flow.
Create test part 3 done with Act and Assert3:48
Act, then await the future, and assert the result. Verify the auth repositories create user method is invoked and the outcome equals a right void.
Create test part 4 and verify4:22
Demonstrate test-driven development with clean architecture by validating part 4 tests that verify the use case calls the president exactly once, with creator, name, and avatar, and no further interactions.
Create test part 5 and run it3:31
Test summary in text format
Create test get_users6:24
Learn to test the get_users use case by mocking the authentication repository and returning a list of users. Verify the repository get_users is called once and no extra interactions occur.

Authentication repository implementation14:13
Authentication repository implementation test 29:12
Authentication repository implementation exception test 39:21
Done test API Exception12:05
Learn to convert API exceptions into API failures, implement repository logic for get users, and drive development with tests that verify remote data source interactions and error handling.
Authentication remote data source implementation test6:29
Test the authentication remote data source implementation, validating success with 200/201 status codes and failures with proper exceptions, and add a dedicated dart test file using the http package.

Cubit and usecase9:51
Cubit authentication test5:19
Learn to write a cubit authentication test by mocking get users and create user use cases, wiring them into the cubit's setup and verifying the authentication initial state.
Cubit and bloc test pass11:29
Learn to test a qubit using the block test package to mock the create user use case, set up dev dependencies, and verify emitted states creating user and user created.
Cubit create user pass4:09
Cubit get users test pass5:12

Requirements

Basic understanding of Flutter

Description

In this course, we will cover how to do test driven development. We will also build a dummy app to learn about it in depth. We will cover almost 100 tests which will involve api mock testing, firebase api mock testing, build correct http response, learn how to deal with incorrect or wrong response from the server.

What is Test Driven Development (TDD)?

In layman’s terms, Test Driven Development (TDD) is a software development practice that focuses on creating unit test cases before developing the actual code. It is an iterative approach combining programming, unit test creation, and refactoring.

The TDD approach originates from the Agile manifesto principles and Extreme programming.
As the name suggests, the test process drives software development.
Moreover, it’s a structuring practice that enables developers and testers to obtain optimized code that proves resilient in the long term.
In TDD, developers create small test cases for every feature based on their initial understanding. The primary intention of this technique is to modify or write new code only if the tests fail. This prevents duplication of test scripts.

Apart from that you will learn correct folder structure of your using BLoC and Provider with clean architecture aspect.

Throughout the testing we will use BLoC & Cubit and show how to manage states during testings.

We will cover how to use the flutter_test package and all the functions in like

1. test()

2. when()

3. expect()

4. verify()

5. verifyNoMoreInteractions()
