Using JaCoCo to measure system test coverage

In this video, I'll show how to use JaCoCo and its JVM agent to measure the coverage of our system tests, with a Quarkus application.

Hallo Sebatian! Just a hi from a developer! Thanks for your great videos! They are specialized videos

thanks, it was very important to understand the use of the agent. even dough I am not using maven but the java command directly, your video really helped me. Thanks

Hi Sebastian, Thank you for for this great video. I have integrated this with CICD and it generates the jacoco report as expected but it doesn't give line by line code coverage the way you have shown.
It says .jar file not found, do we need to pass anything extra when integrated with CICD?

Hi Sebastin, This is really good. But what if those UI Automation tests are written somewhere else and not coupled with your java-application? How you could calculate how much code coverage it is doing with UI-Automation for any microservice app?

Can you please share one example with gradle also

[ChaiSuttaClips]

How you have created jar of the web application, Could yuo please help or share git link of quarkus code and jar

Great video it was very helpful, I just wanted to see how can we exclude few classes and methods which we don’t want to be the part of the jacoco report.

I tried excludes=/com/abc/xyz/class but somehow it still shows the output in result

everything worked but i could not see the coverage in the report. any reason. started java -jar target/demo-1.0-SNAPSHOT.jar then executed some curl script then mvn \

then opened the index.html from site. it has red color only in the coverage report
