Tests Coverage with Jacoco, Unit and Integration Tests | Spring Boot Backend #9.4

In this video I show how to obtain the tests coverage with Jacoco, for both the unit and the integration tests. I show the configuration of the Surefire and Failsafe plugins to run the unit and integration tests separatly. And finally I show how to use the Surefire and Failsafe plugins to feed Jacoco.
This is the fourth part of the ninth video of a playlist where I show how to create a Spring Boot Backend, how to create a website: • Spring Boot
Content of the video:
* how to configure the Surefire and Failsafe plugins;
* how to configure Jacoco;
* how to feed Jacoco with Surefire and Failsafe;
* how to see the Jacoco results from a browser;
* how to obtain the coverage percentage from the terminal.
Command used in the video (you must replace > and < by their symbols, because TH-cam doesn't allow to print these symbols in the description): cat target/site/jacoco-ut/index.html |sed 's@\(.*\)Total</td><td class="bar">\(.*\)</td><td class="ctr2">\(.*\)</td><td class="bar">\(.*\)@\3@g'

Thank you very much for your clear explanation!

[@TheDevWorldbySergioLema]

Glad it helped you!

[@dinobulja]

Thank you. Great video/explanation. But, it would be nice you added to this video also how to display code coverage in GitLab per unit and integration test and how to add visualization in gitlab. And also, how to call the pipeline jobs separately now that you have added the surefire and failsafe plugin.

[@TheDevWorldbySergioLema]

That's a lot of topics for a single video 😅
You can watch another video I have about Gitlab if you want more details about how to configure jobs: th-cam.com/video/bW7VMeSHFNg/w-d-xo.html

This video was helpful for me to setup Jacoco. Thanks.

[@TheDevWorldbySergioLema]

Glad it helped you

The final part of maven command execution should have been included in the video. Adding them for completeness:
mvn clean test --> Runs unit tests and creates code coverage report for UT alone
mvn clean verify -P integration-test --> Runs IT and creates code coverage report for both UT & IT
mvn clean verify -P all-tests --> Runs all the tests & creates all the report

[@TheDevWorldbySergioLema]

Maybe you're right, but my goal was to show how easy is to obtain the unit and integration tests coverage. If the viewers want more information it's easy to find it in the Jacoco documentation.

Thank you very much!!

[@TheDevWorldbySergioLema]

You're welcome!

[@replikvltyoutube3727]

Thanks for the video that better explain configuration in pom

[@TheDevWorldbySergioLema]

You're welcome!

[@DinMamma002]

Does this also work if you make http requests to your web server instead of using MockMvc?

[@TheDevWorldbySergioLema]

I'm not sure about your question? You mean make requests manually?

[@rangalakshmir.t8541]

could you make a video for code coverage for maven multi module project?

[@TheDevWorldbySergioLema]

I will put it in my TODO list 👍

[@kushmishra9197]

I have two different repo - one containing integration tests and another the repo which needs to be tested. Can I know the test coverage of these integration tests ?

[@TheDevWorldbySergioLema]

I know no system that can merge the two coverages.

[@808sprng]

I wish it worked for me 🥶

[@TheDevWorldbySergioLema]

I'm sorry, what's the problem? Maybe the version of the libraries I use in the video are not yet up to date
