Test Driven Development with Spring Boot - Sannidhi Jalukar, Madhura Bhave

Ever wonder how to test a hard problem like caching or write an integration test without making an external API call? Or come across a situation where testing something was so hard that it never got tested? A lot of developers today find themselves in situations where they are unsure of how to write light-weight unit tests. In our presentation, we will talk about how to do Test-driven development for a Spring Boot application and how some of the latest Spring Boot annotations and utilities make that easy. We will deep dive into some tricky real world testing scenarios that have baffled us in the past such as database queries, caching, reactive components, and message brokers.

Something that often messes up importing dependencies in IntelliJ is this: in preferences, under Build, Execution, Deployment / Build Tools / Maven / Importing, un-check the checkbox that says "Keep source and test folders on reimport". I don't know who would ever want this checked. It basically makes the IDE ignore when you try to reimport dependencies.

Grate demo and good explanation about various layers of testing, special with mockito.

In the beginning, it was good because I have already seen Phil webb Spring Boot testing session. You guys are also good but network connection or something it get spoiled there. I loved it the beginnning abd now xou can see in teg i ma alos gettngi bda. :P

I enjoyed it a lot. But from what I recall, Sonarqube considers a critical issue having private methods in the controllers...

very good overview for the different levels of testing in a spring boot application

[@nawabsonu]

Thanks for doing presentation on this. It was good at start, kind of lost interest once network problem started happening and we started into caching. Personally, I also felt we were going too fast with the presentation giving little time to understand what is written.

[@jesse2006]

please update to talk about using Jupiter jUnit 5 as the annotations and process is different

I am surprised to see IntelliJ idea instead of STS :-)

[@AhmetMurati]

Spring Tools Suite has some bugs especially when it comes to compiling, running the project

[@BharCode09]

IntelliJ is IntelliJ! Also the more we are addicted to that, dumber we become, bcz it's so IntelliJent!

[@leszeknagooglach]

@DataJpaTest is itself is annotated with @AutoConfigureCache with @PropertyMapping("spring.cache.type") CacheType cacheProvider() default CacheType.NONE; So, is there really caching when using repository.save(entity) in a test?

[@CharlesRay87]

Don’t get a purpose of testing repositories instead of larger units like application services or even modules. It is close to the “test-per-class” antipattern. I think we should focus more on testing behavior than implementation :)

[@kevinjom1117]

The driven design part and refactoring part are missing in this video though

[@omkarmanjrekar6645]

This is really nice starting point for someone learning testing with Spring. Is there a github repository for the code shown in the video?

[@darkenergy7121]

It was given on the last slide. Busted. You didnt watch the entire presentation..😂🤣😅

[@VLADICA94KG]

One question for CachingTest: Why the configured @AutoConfigureTestDatabase when they used @MockBean on CarRepository? It won't reach out memory database anyway....am I wrong? Thanks

[@Skiamakhos]

Hey does anyone know if there's an equivalent presentation for doing TDD in Spring MVC *without* Boot? Boot seems to be the buzzword of the day but a lot of us work on SpringMVC projects that didn't get Boot for whatever reason. How do we do all this "old school"?

[@saurabhmishra8151]

If anyone's completed this tutorial, could you provide a link to the pom.xml file?

[@mohammedershadulhaq9865]

This is not working in latest spring boot pls update the video

[@tharindawicky]

They are working on "Maven Project > Offline Mode = true", that's why the dependency did not download from maven central.

[@nickdan007]

Thanks, I’m gonna check it, cause I had the same issue and I have to close the project and open the pom as a maven project so the dependencies load again in IntelliJ workspace .idea

[@hazerend1402]

Sometimes intellij is having that problem,missing dependency, you just have to invalidate cache and restart intellij

[@seweryn3001]

ANYONE: what is the starting Spring project? What dependencies? I doesn't work on my end. Probably incorrect versions/lack of dependencies on my side. Thanks

[@kanaillaurent526]

I'm lost with Spring. Why? Because Before we used to init mockMvc with "MockMvcBuilders.webAppContextSetup(this.wac).build()"; wac being "ApplicationContext wac= WebApplicationContextUtils.getRequiredWebApplicationContext(servletConfig.getServletContext());" In general there are too many ways to do the same thing and it always change. Am I wrong ?. And because I have the habit to keep all code that worked for me somewhere, I never know if my knowledge database is already obsolete. : -( Not even know if that demo works nowadays in 2019 and if it's the best practice. What should I do?

Read again from the official documentation for every release.. I think it's not only spring but software engineering...

Nice video, however, CrudRepository issue is about incorrect library but not the internet.

[@dmitrypotenko4950]

The library was perfectly correct. The offline mode just didn't work for some reason. They should have tried resolve dependencies in the console by the command mvn dependency:resolve and see in the console what went wrong. This is the best what they could do.

why not restarting the IDE, close/reopen project, maven clean, or searching google

[@dmitrypotenko4950]

Search in google, not knowing the reason of the issue and without the internet, is not the best idea, you know. All other pieces of advice as (mvn clean, close and open) would have hardly helped them as it has nothing to do with reason why maven could not find library in the local repo.

'RED' is a universal color for danger. 'Restarting an APP' when it misbehaves is the universal solution to fix it. Not trying to even consider doing so is unprofessional. When the presenters were out of their home preparation - they sucked miserably.

[@aliakbarpour6926]
