Spring Boot Unit Testing With Mockito - 1. First Unit Test

[@tejeswar]

Most underrated channel, the vast of many tutorial channels in youtube.

[@Lykkos-321]

I'm taking this course in a chill mood without anxiety because is from Teddy Smith, and I know I will ending up understanding all of it without any kind of stress, your previous tutorial of Spring Security helped me a lot!!

[@carrotblog1746]

Thank you so much I don't know where to start till I found you.

[@house_d2024]

Teddy you helped me a lot ! May God bless you

I was struggling to write test cases in junit. After watching your videos, it's a cake walk. Thanks a lot, you're really a great teacher.

[@TeddySmithDev]

Just wanted to add this in case you a newer developer that does not feel comfortable using git to time travel back before I wrote unit tests. Feel free to clone project and just delete Controller, Service, and Repository folders inside Test to follow along.

[@shouvikxiv]

Loved it. We need more pee examples.

i real life loled

Real men test in production

If you are following TDD, should you write the tests out first before writing the code? Then change the code to pass the test as opposed to changing the test itself?

[@ijazhaider6072]

Provided that your test case has validated all business requirements and handled all edge cases. Then yes.

[@RohitKumar-dz8dh]

Do we need to configure our H2 database by removing other database configuration for repository test case?

[@TrungRichie]

Can you help me to solve this problems: - When I used 2 annotations the same as you: @DataJpaTest and @AutoConfigureTestDatabase, I got an error: Error creating bean with name 'dataSourceScriptDatabaseInitializer' defined in class path resource. And I can't find any ways to fix it. - When I changed it to @SpringBootTest, everything works fine. Thank you for your help and answers.

Why is the entity class is not identified in the reposoitory test class

[@JonathanBrooks-k6l]

I run DDD, disaster driven development

[@Camupof]

Thank you very much for your video. My tests are passing, but I'm getting the following warning: "Java HotSpot(TM) 64-Bit Server VM warning: Sharing is only supported for boot loader classes because bootstrap classpath has been appended." While some sources say this is a non-critical error if the tests pass, others suggest otherwise. Should I be concerned?

[@TeddySmithDev]

If I remember correctly, this same warning occurred in my terminal. If this isn’t for production app, I’d just let it go.

[@Lavless12]

Isn't Arrange Act Assert affiliated with TDD and Given When Then with BDD?

[@jasongoossens]

Honest question: why are you testing JPARepository methods? Unless you have custom code in your repo's, wouldn't you skip that, and focus on the service and controller layers? (I assume you're mostly using the automagic methods, and not JPQL, or native SQL)

[@TeddySmithDev]

Yeah testing repository is overkill. But I notice that people are googling those keywords so need to include them from SEO standpoint. In real life I would concentrate all the tests in service + controller layer.

[@ShubhamSingh-xu3bo]

Could you please suggest any documentation why you have used @mockBean in ControllerTest and @Mock in service

[@TeddySmithDev]

javarevisited.blogspot.com/2022/08/difference-between-mock-and-mockbean-in.html#axzz7msbBSJ6G The differences are very unclear and documentation is poor. My interpretation is that @MockBean provides Application Context, but I'm curious to those that think different.

[@jackbaker995]

the bladder example, lmao

[@theodulesaintil5725]

Hi Teddy, good job and thank you for the tutorial, but i can not use the builder method in the PokemonRepositoryTests class even i added the @Builder in the pokemon model. do you have any explanation?

[@TeddySmithDev]

Lombok installed? and you may need to install Lombok IntelliJ add on (sometimes it comes pre installed)

[@theodulesaintil5725]

@@TeddySmithDev first of all i am using Spring Tool Suite as IDE. and yes i have added the lombok dependency in my pom.xml and import the lombok.Builder in the Pokemon model. is there another step to complete?

[@KrscanskaApologetika]

@@theodulesaintil5725 Lombok never worked for me too, I lost days trying to make it work, after exhausting all the possible options I don't use it anymore

[@woistdasniveau8290]

Does this also work if i use MySql as the Database in the main package?

[@RohitKumar-dz8dh]

While using H2 for test case i am getting error of tables not found. Anyone has solved this then please help 😊.

[@МаксимЯрема-е8щ]

Thanks for the tutorial. I noticed that the junit dependency is already present in the spring-boot-starter-test, so I guess there's no point in adding it again, right?

[@alpersener4269]

yes

[@erengunduzvar]

Which tool do you use for drawing schemes ? It's doesnt look like draw io or Excali.

[@TeddySmithDev]

Microsoft whiteboard

[@erengunduzvar]

@@TeddySmithDev Thx a lot great content 🙏

[@chanprakash252]

Dude, say what you type, helps us follow along better.

[@yesno5286]

This topic should be a strand alone topic, and should be baby steps, i have a total of 45 min experience with testing and i cant follow along.

[@NourWanis-b5x]

hello teddy , i have this problem : java.lang.NullPointerException: Cannot invoke "com.example1.pro.repository.GarageRepo.save(Object)" because "this.garageRepo" is null Can you please help me..

[@TeddySmithDev]

You probably have a dependency injection issue. Make sure everything auto wired correct.
