I’m very pleased that it was helpful!

You’re welcome!

Thank you!

It fails because it doesn't flush. Without specifically flushing it's up to the framework to do the flushing and we have no control of when that happens. The constraint check only happens on the database level after the flush.

@@codewitharho I understand. Thank you.

Always nice to hear it's helpful content!

Probably because @WebMvcTest is a slice that only loads part of the application context. You could test your endpoints without the context path with @WebMvcTest. Then just have a single @SpringBootTest that validates the context path.

Unfortunately not (yet). I have been struggling to find time to make more in-depth videos.

If you ever made one that would be awesome!@@codewitharho

Unfortunate but we can try to share information!

Happy to hear that!

Examples can sometimes be too simple, right? The takeaway here is to not mix framework details in your business logic tests.

Glad you liked it!

Thanks a lot for the kind words! It is always warming my heart when someone finds the content useful.

You’re welcome!

I’m glad it has been useful!

The point here is the ability to write unit tests without the Spring framework. When choosing examples you have to always choose between simplism and realism.

The goal is to test that validation takes place and endpoints respond, not the actual Spring implementation of such concerns. For that to happen, it’s still our job to add correct annotations and configurations. Testing the business logic is important, yes. But your business logic doesn’t care what technology is driving it. Unless you have a CRUD app you probably shouldn’t test your business logic through the controllers. Here’s an article that goes much deeper in the architectural side of things: www.arhohuttunen.com/hexagonal-architecture-spring-boot/

Looks like I have forgotten to reply, but that sounds like a good idea for better understanding.

Sounds like maybe it’s not making the request at all. I’d first make sure that it actually does make the request before looking further.

@@codewitharho i found the solution, baseurl was incorrect 😊

Have you configured JaCoCo correctly? Just running the tests alone is not enough, the coverage must be measured with JaCoCo or a similar coverage tool.

Can you be a little more specific?

Thank you!

Thank you! I should eventually get back to it - currently in the middle of moving places and renovations.

Cool!

I haven’t been using Spring Batch much but I won’t rule out the possibility!

Thank you!

You’re welcome and thanks for the kind words!

​@@codewitharho Are you planning a WireMock series? I'm very impressed with your approach to the subject of tests. I will definitely recommend this channel further, it's a real gem. Thank you for your amazing work.

So glad to hear it was useful!

You could, but using constructor injection makes sure that the class cannot be modified after instantiation. Using constructor injection also prevents circular dependencies in Spring.

Well, I guess any framework can and will be abused without some care. Annotations can make it too easy to pick the ”easy” solution if you don’t pay attention. You can always try to point people to informational material, like these videos. 😉

It largely depends on your architecture. Try to keep technical concerns separated from business logic and then test those in different types of tests. If you are following a layered architecture, then typically the service layer should be mostly about just business logic. The web layer and the database layer are more technically oriented. I have an upcoming article about architecture and testing, so stay tuned!

@@codewitharho I could’ve said the same) I ask about some small thing. It’s hard to explain. It’s more about real case and difficult cases) what should we do if we faced a difficulty? FirebaseAuth is a final class and a bean, and it’s a class one of the dependencies I have) it’s a real hard case I have and I don’t even know how to test)

I can only suggest creating a wrapper class for difficult dependencies and then mocking that wrapper class instead. Have you watched the 5th video in this series that creates a wrapper for WebClient?

TestEntityManager helps you to test the full cycle of storing and retrieving the entity, e.g. flush the persistence context cache and then read the entity from the database. Otherwise the test could just end up reading from in-memory cache.

You’re welcome!

Thank you!

Thank you very much!

Moi ja kiitos paljon! 🙏

That’s quite a specific topic and unfortunately don’t have experience on.

Thanks, I appreciate that a lot! I have been struggling to find a good work life balance and am currently trying to arrange things so that I can focus more on this channel.

Much appreciated!

Thanks for the suggestion! Spring security is quite an important topic.

​@@codewitharho Thanks for the quick response sir. Currently I am disabling the filter (AutoConfigureMockMvc(addFilters = false) ) . Is it right way to do unit testing for the secure endpoints?

This is quite an extensive topic to discuss in the comments but I would suggest taking a look at the WithMockUser annotation as well as SecurityMockMvcRequestPostProcessors which you can use with the with() method available in MockMvcRequestBuilders. I will consider writing a post about it. Good luck!

​@@codewitharho Thank you sir, It really helps. Sir, only one request please don't stop making tutorials. I have watch tons of videos related to spring and also enrolled in Udemy course. But the content you delivered is 100% to the point, easy to grasp and in depth. Please continue the series related to spring in your channel. And once again Thanks for creating such an awesome series.

@@p.p526 That is much appreciated. I have been struggling to find a balance between work, life and this channel and am currently trying to arrange things so that I can focus more on this channel. Thanks for the support!

That’s correct, tests should be independent. If you run them parallel and they affect each other, we are not talking about unit tests.

Thank you!

Nice! Yes, it’s handy.

Thank you!

Thanks! I’d be happy to get more views but I guess it’s kinda small niche.

@@codewitharho Yea it's too bad the crowd looking for this stuff is so small. These are by far the best structured and explained of the hundreds I've been though so far. Thanks for sticking to it!

It takes time - like in real life: a well known store gets a lot of traffic from old customers, while new shops gets less traffic. patience - with time some viewers will like this videos and other videos by @codewitharho and it will promote the channel. It's superb. Love your videos Thank so much. Kiitos (Love Finland as well).

I don’t have an article about MySQL specifically but you should be able to follow the article that uses Postgres and just replace the Postgres image with a MySQL image.

Thanks a lot! Comments like this really encourage me to keep doing what I like to do.
