Spring Boot Testing | Writing JUnit Tests using JUnit and Mockito | Java Techie 

you save my life, because of this i passed interview

Very very helpful. You are a life saver. I was stuck on this issue for so long. And trying your method solved the issue within seconds. Thank you so much!!!

Simple and Concise. 100% to the point content. Thank you so much for this educational content.

very helpful. like how you showed what the mock object does using a print statement in service layer.

❤️ you brother. U have solution to each and every problem. May god bless you for the service you are doing towards the people

The only video where i learned this concept properly, amazing

Awesome content, pretty straight forward. Some people are complaining about communication. Don't worry about accent/communication as long as your content is good.👍🏻

Before this video i watched many others related to Unit test, and the make it more difficult. After watching your video, i started to implement tests directly on my codes!!! thanks for making it simple to understand.

Brilliant, precise and to the point video... Thank you Sir...

Very clear explanation of mockito and junit. Thank you very much.

You just saved my all time n efforts to learn mockito. Thanks

Awesome your effort please keep continue brother.

Thanks for covering Mockito. I believe this is Junit 4. Can you please cover more test cases with Junit 5 and with different situations including how to handle exceptions and all?

Thanks for proper and complete video for API basic testing.

I have learnt a lot from you. Awesome tutorials

Very Good Example !! Thanks for all efforts

point to point content, this really helpful for us.

Thank you so much. you made my UT very easy now. very simple and easy way to understand.

Thank you very much, sir. Great explanation. :)

Sir, thanks for explanation in easy to understand language

very helpful sir thank u for this video...

Great Job. easy to understand. I would appreciate if you elaborate more.

So helpful. I suggest your video to many of my colleagues

I'm fairly new to Java (and Spring). I see from the source code that 'UserRepository' is of type Interface. My understanding of @MockBean is that it instantiates an object of type 'UserRepository' within Spring's application container. But this is confusing to me, since I believe that Interfaces cannot be instantiated, only classes. So how does @MockBean instantiate an object of type 'UserRepository', which is an interface? Thanks for the great tutorial btw!

clean and well explained. Thanks man.

Thanks Basant Bhai . You Rock.........................

Hi, if you having this warning: "no test found with test runner junit 5", you need to import: import org.junit.jupiter.api.Test; insted of import org.junit.Test; Btw: Thanks Java Techie

Wow awsome explanation.... Bro

You always make things easier for me to understand. If I may ask do you have full completed course and other full courses that are related to spring framework

Thanks Sir! I also want to clarify test case for exception handling, So please upload a video for that as well...... Thank you so much sir.

Hi on line No 51 how you were able to do assertEquals on two objects. I had to override equals method and implement it to do equals as I was getting false because it was just comparing the reference value of those 2 objects. Please guide me on this. Thanks,

thank you so much SIR very nice and clear explanation!

You have good concepts. Just work on communication. keep it up !

your videos are very helpfull u r awesome

Nice explanation sir , thank you

superb sir , good explanation.

Thank you for useful content...

It's very clear.. thank you bro

its simple, straight and Good

Persistent applications are especially important for which to write tests. You can have a functioning product which gives no errors, deploy said product, and then find out some time later that only half of your data persisted. Or even worse, that the DB overwrites itself each time the program is restarted.

Very good tutorial..very simple..small request.. some words are difficult to undertstand while u explaining so that some points are missing...try to make it clear...rest is very best..U have done a simple and great job..

Thanks for sharing the knowledge. Please share how to test put method also.

i like that way u teaching

Hi, thank you for the great video. One question - You did not add when(repo.delete).thenReturn(user). Is it not needed in delete case to make sure actual delete method is not called?

Thanks for nice explanation.

Thank you so much for the useful content

@javatechie Hi Techie, if I want to exclude any java package from junit coverage , how can I do that?

communication is good as easy to understand and content is also good thanks

clean explaination

Thanks for sharing this info.

This saved my time. Thanks a lot! Please work on your communication, You'll surely reach heights.

Its vry clear thank you

Thank you for your nice video

Very well explained I have one doubt like if user id is checking whether he is existing or not then how this dummy data will works?

Very clear explanation

Your videos r very useful sir....

Great job brother👍👍👍

No non-sense guy with awesome content!!

Hi Team , don't be confuse in repository.findUserByAddress() , if you observe when(dao.findUserByAddress(any)).thenReturn(Any user object) so irrespective of any address value i will get that user object which i mention in thenReturn , that's what mockito does for use

can u please upload a video on payment integeration api like razorpay or instamojo with spring

nice video basant bhii

Hello,can you please tell me how to write test cases for the Dao layer?

Thanks! Really helpful!

Thumbs up! before even seeing the video

Very nicley explained Thanks

Nice and simple video

Awesome man. Thanks

How to test the Data Layer ? There we won't use mockito ,right? Since we want to test the Data layer with actual values retrieved, inserted, updated and deleted from Database?

Hello Sir, Thanks for the session. It really helped just had some doubts. For creating test cases for DAO layer do we mock the methods without hitting db or should perform the db operation and then test?

Good explanation 👍

Nice. Really helpful

Thank you bro. It's really helpful and can you provide the depth knowledge for same like exception mocking part and if we have more parameters in method how we can handle.

good vidoe..very helpful

Awesome..

great sir

Should you only add tests for service layer? Or should you also add tests for "controller" and "data" layer also? Thanks

Thank you sir. I have 1 question, when running 1st testcase, I understand what findAll() does, but when was those 2 entries inserted in mock repository?

Very helpful bro

Hi, very nice your video. In the example you used a list in FindALL. How would you test if you were a PAGE type? I can't find an easy test example.

wonderful

nice video!

Kindly please let me know if you have any video with the same content but for TDD development

Sir search is not working like you provide anything in adress it will give you same values you passes as parameters in return statement .thenReturn(Stream.of(new Post(values))); It must be like this if the address you provided matches then it will give values otherwise give empty as result but in both case it is giving exact same values

What does it do when we are trying to mock db calls for saveusercart does it save the entity in some cache?

bhai bhala video heichi .......

tnx a lot bro...

excellent, thanks

good video

Good explanation

Helpful 👍

Hi JavaTechie , can you please upload an example for @MockBean and @Spy for Spring Data Rest
