You changed my life of spring developper and i'm ready to buy on your plateforme a complete course of how to deploy spring boot project on aws (AWS Amplify, AWS S3, AWS RDS, AWS EC2). It will be a pleasure to follow such course. Thanks for everything

[poorpanda]

Perfect Upload. I was just learning about unit & integration testing & you've uploaded at the right time. Thanks a lot !

Can you make a video about using Redis in Spring Boot and PostgreSQL?

[kanehamath]

Interessting and well understanding, big thanks

[jnayehsirine]

Always providing high quality Content, THANK YOU !!

[davidb.]

Literally amazing tutorial, the only thing missing was testing the controller.

Hi Alibou, Your content is very good, much appreciated. It would've been even great if you've covered code coverage as well.
Thanks

Thank you for this video. Please continue topic of testing.

(By the way, a "mock" is an empty version of an object, and a "stub" is a mock with some functionality added back in.)


00:00 Testing is important, here's why

06:05 What is Spring Test? 
(tl;dw it's a testing library for Java).

8:49 How the example program is organized 
(tl;dw StudentMapper has a Student object with student info, and has a StudentResponseDto object (Dto stands for Data transfer object). StudentService has a StudentRepository object and a StudentMapper object.)


10:59 Making a test class for StudentMapper

14:58 Test Class exists, first (Hello World) test function 

```
@Test
public void testMethod1(){
     System.out.println(“My first test method”);
}
```

16:50 The SetUp method, @BeforeEach

19:01 The TearDown method, @AfterEach

20:42 @BeforeAll (BeforeClass) method

22:30 @AfterAll (AfterClass) method

23:55 First actual test, and what the StudentMapper functions do

29:57 First test is done and runs

30:06 Causing the first test to fail

32:07 Practice Exercise - implement test for toStudentResponseDto method

32:50 Practice Exercise answer

34:44 Given, When, Then, test structure

35:39 Third test: studentDto to student if null. 

38:15 Fixing the source code to handle null. Adjusting test to expect exception, and getting the exception message (assertThrows(exceptionType, () -> { code });)

42:31 Explanation of StudentService and database, test isolation with mocking (Mockito)

45:01 Creating new test class for StudentService

46:30 First and second @Mock

47:33 @InjectMocks

48:22 Opening/starting the mocks

49:21 First test method for StudentService, saving a student

52:48 Why the result is null/failing. Mocking functions for test isolation’s sake. when().thenReturn()

57:31 Test with mocks (and stubs) is ready and runs

59:06 Making sure the methods were only called once, using Mockito.verify() 

1:02:20 Practice Exercise - test findAllStudent() method, using mocks (and stubs) as needed

1:02:53 Practice Exercise answer (including using mockito any() method)

1:06:33 Practice Exercise - test findStudentById() method

1:06:52 Practice Exercise answer (including Optional.of())

1:10:07 Bouali Ali is proud of you

1:10:13 Practice Exercise - test findStudentsByName()

1:10:45 Practice Exercise answer

[melissapereira]

can you do more videos about testing ? perhaps testing the controller layer ? i loved the lecture, you helped me a lot. 😊

[diagspring]

Very nice boulai Ali thank you☺️☺️☺️🎁🙏🏾🙏🏾 for the video happy the new year

[maleeshasandakalum]

Thank you very much. Really appreciate your for your effert ❤❤❤❤

[buntykumar]

please make more videos on unit testing and mockito which used more complex code like service class depends on multiple different service class and use spring security for authorization and authentication and encryption decryption for request and response object. Your video is really helpful and thanks sir for sharing your great knowledge with us.

[yosefhagos]

Great Video!!! Could you provide us with the link to the repository? How to test controller classes ? How do you test the database connection and whether data is read and saved correctly?

[ivansanchez]

Do you have a complete course on testing, where we can get the initial code to learn along with you? I enrolled into your platform, the content is awesome, thanks for the effort.

[pranavmahajan]

You are a fantastic teacher. Thanks a lot. Can you please cover integration testing of REST services ?

[firas_hkimi]

After One month Sir ALi Bouali come Back 🥰

[raghusama]

Do we have the video of development / Implementation of that Student project ?
