Hi Java Techi,
If you have already covered how to integrate jococo code coverage report to Jenkins can you please share video link?

[@MohdSalman-xq1cw]

Cool..............

[@jogeshwarghosh5722]

Thank you sir for posting these videos.

great thanks

[@payalsinha1248]

Sir, in my project I have to find the code coverage of integration test cases written in cucumber, but we have 2 different projects one is for source code and the another is for cucumber, can u plz suggest me how to generate the report in this scenario

[@malius97]

Thanks

[@kasthurirengansrinivasan7183]

thanks boss

[@harshavardhanreddybommared4660]

Hello
The explanation is crystal clear. I am facing an issue while running maven test.
I am working on a maven multi module project and try to run the maven test.
I shows the below warning message and the report is not generated.
Classes in bundle 'core-module' do no match with execution data. For report generation the same class files must be used as at runtime.
Please help me with this.
Thanks in advance!

[@Javatechie]

Are you trying to generate report for each module individually?

[@harshavardhanreddybommared4660]

@@Javatechie No for one particular module alone where I have my backend code (Java Code)

[@BLACKLASHXXX]

Anything on gradle project integration

[@motolola]

Very nice, and simple explanation ... How do we fail Maven build when a certain level of coverage is not met? Thanks in advance.

[@Javatechie]

Hi Akinjide,
Thanks dude , didn't get you could you please elaborate more

[@motolola]

@@Javatechie Normally, when you run "mvn clean install" the project builds successfully if conditions like test cases etc passes ... I was wondering how to add more conditions like "if test coverage is lower than xx%, fail the build", maybe another condition like "Checkstyles, "PMD" etc ... How to include with maven build. Thanks for your quick and awesome response. you are touching lives.

[@sivasiva-wn6os]

Bro mine is showing zero clasess covered how to get it done

[@azimsurani4246]

Can you do it for JUnit 5 because I am struggling to implement the same with Junit 5?

[@Javatechie]

Okay I'll try

[@ChaseGouldMMA]

@6:25 which repository do we find the plugin text which was copied? Thanks

[@Javatechie]

Source code link mentioned in video description go to pom.xml and do copy and paste

[@sureshmanne7245]

Any reason why you didn't use stringbuilder reverse method which comes from api directly ?

[@Javatechie]

No reason while explaining it . But never use SB to reverse a string as it will impact performance

[@muralijava552]

could you please make a video, how to set the threshold for junit(if JUnit coverage falls below certain threshold)

[@ruchiSAHAY11]

Hi..were you able to find a solution to this?

[@ManojKumar-jq2hx]

clear explanation thank you, if any test case is fail then jacoco is not generating the report, so may i know how we can skip failed test cases, is there possibility for this

[@Javatechie]

It should generate , did you compare with my source code and follow the same

[@ManojKumar-jq2hx]

@@Javatechie , thanks for quick replay, while running the first cmd only I got the build fail so that's why I didn't tried for sonar:sonar cmd. Now I have tried even after build fail also report got generated. Is there any way to skip failed cases because its causing build fail.

[@Javatechie]

You can add vm argument Dskip.test

[@msapurvapahade]

what should be the code coverage percentage ideally?

[@Javatechie]

It depends on Rule set on coverage

[@krypton2295]

Run Maven install then refresh your project once please

Hi sir, Will jacoco reports will generate when a test case fail.

[@Javatechie]

Yes it will

[@thanujames1668]

@@Javatechie may I know how

[@thanujames1668]

right now I could only generate reports when all the test cases are passed. I need to generate the jacoco reports even when some of the test cases fail. Do I need to add any dependency for it ?

[@muralijava3603]

If I have a multiple packages, how can i exclude one package from report...I could able to execute by excluding...but report getting the excluded package...any help..?

[@Javatechie]

In pom there should be some options please checkout maven repository and modify

But you none of your examples start from adding any dependies or other things from scratch .you use to just start from middle
