Software Testing with Spring boot and Mockito Framework

[@youbabagayogo3052]

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

[@BoualiAli]

now, all my content is and will be for free. No one should pay to learn You are welcome to contribute if you want to

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

[@BoualiAli]

Glad it was helpful!

*Table of Contents* (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 (MockitoAnnotations.openMocks(this);) 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

Thank you for the simple and straight forward explanations.

[@melissapereira6957]

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

[@BoualiAli]

Yes, soon

[@jnayehsirine6222]

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.

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

[@marcincylkowski3004]

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

[@BoualiAli]

sure

[@yosefhagos4788]

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?

[@diagspring144]

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

Yes, soon

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.

Awesome dude ❤🙏🙏🙏

[@BoualiAli]

Glad you think so!

[@christianjaena1803]

Should you write test first before implementation or the other way round?

[@zee8105]

Hi Bouali , do you have any videos on integration testing? it could be a payed version too, really interested if you do. thanks!

[@krishnamadhav7639]

Can you please upload the link for the code used in this tutorial. I couldn't find it in the description.

Could you do a video about how to be in testing with jwt-security ? how to add jwts or fake jwts when testing and how to test login or auth methods, endpoints?

[@BoualiAli]

good idea

Waiting for it

[@BoualiAli]

there is no app for that. just showcase services

can you tell me which repo, you used for the testing, can you provide the link?

[@BoualiAli]

I dont have a repo for it

How to see the class diagram that you showed?

[@whiz-code]

If you are using Intellij, go to the module / directory, right click and choose diagrams, Its one of the last options. Thank me later.

[@georgepro8481]

I think that the repository level must be tested first of all. It doesn't need to test basic CRUD operations of a repository. But we have a lot of fun besides. For insance, test the fact that repository realy gives an id for a new entity. Does the audit feature (createdAt, modifiedAt) realy work? Does it throw correct exceptions? Does your SQL query correspond to your expectations? How to mock DB (embedded, docker) ...

[@BoualiAli]

This is the integration tests level. I will cover it soon
