Introduction

The JaCoCoverage Plugin is a Netbeans plugin that enhances the existing NetBeans functionality with new code coverage features.

The plugin works as a transparent additional service that colors all java files according to the unit tests coverage information. With code coverage enabled user continues to work with his/her project in the usual way but can easily view the test coverage of the project classes.
The code coverage plugin will update the code coverage data and refresh editors markup every time a unit test (or any selected Ant target) is executed for the project. Currently the Java Application, Java Library, Java Project with Existing Sources, Java Web/EE/EAR, NetBeans Module projects are supported. Maven projects are already supported by NetBeans, please check http://wiki.netbeans.org/MavenCodeCoverage.

Coverage collections are based on JaCoCo in order to support Java 5,6,7,8 bytecode. Take it as a modern alternative to the EMMA and Cobertura based plugins.

JaCoCo is a free code coverage library for Java, which has been created by the EclEmma team (http://www.eclemma.org/jacoco/).

Test cases in subpackages

How does Jacoco determine wich test cases to run ? From my limited testing, it appears it runs only tests in the default (root) package. How to run tests in subpackages ?

Re: Does this work with multiple projects?

Hi,
unfortunately no, this feature is not implemented.

Does this work with multiple projects?

If I have one NB project that uses another NB project as a library, can I get it to run code coverage for the two as a pair? I ask because the project we intend to use this with has ~20 NB projects, and there is no unit testing within each project. We would like to have a metric for how effective our end-to-end testing is, and are hoping to use JaCoCoverage for this.

Customizing Jacoco

Thanks for the plugin, I have a couple of enhancements when you get the time out of your busy day. First I need to be able to tell Jacoco what build.xml to run. It seems to automatically pick up the generic build.xml not the nb-build.xml that netbeans is using. Second I need to tell jacocao where my .jacoco and html directories are located. I am using Netbeans 8.1. Thanks in advance.

Re: Run JaCoCo from Ant?

Thank you. I think that got me as far as I can now. I need to figure out how the get the Jenkins plugin to report anything other than 0%. I've tried JaCoCo 0.7.5, 0.7.4, and 0.7.2 (the newest prior to the date of the plugin).

The cleanest option is to specify the "-Drun.jvmargs..." as a java option. For some reason the "test.run.args" does nothing.

Re: Re: Run JaCoCo from Ant?

Do you launch Ant from command-line or NetBeans?
You can add the javaagent into the "test.run.args" (test program) or "run.jvmargs" (run program) keys.

You can take a look at https://github.com/jonathanlermitage/tikione-jacocoverage/blob/master/tikione-jacocoverage-plugin/src/fr/tikione/jacocoverage/plugin/action/ActionJacocoOnAntTaskJ2SE.java#L182 to see how I add the javaagent to the Ant tasks.

Also, you can simply start Jacoco with the JaCoCoverage plugin and look at the NetBeans output.
You'll see something like "ant -f .....JavaApplication1 "-Drun.jvmargs= -javaagent:\"....jacocoagent.jar\"=includes=javaapplication1.*,destfile=\".....jacoco.exec\"" run".

Re: Re: Run JaCoCo from Ant?

Hi,
I don't know Ant, so I don't know how to add a javaagent. I tried an example I found to add a javaagent line to the project.properties, but that doesn't appear to have any effect (it defines a test.run.args and didn't specify if that needs to be used somewhere).

Jenkins has a tool to parse it, it only needs the .exec file. For interactive use I can use the NetBeans tools (and thanks for that!).

Re: Run JaCoCo from Ant?

Hi,
you can add the JaCoCo javaagent to the command-line args in order to generate a JaCoCo report file (jacoco.exec), but you'll still need a tool to parse it :(
I could add an option to generate a report by loading an existing jacoco.exec file...

Run JaCoCo from Ant?

I have NetBeans set up to run JaCoCo from the context menu, but I need to run it from Ant (using Jenkins to auto-run Ant tasks). Is there a way to have JaCoCo run as a part of the Ant 'test' task, or similar?

Netbeans Platform Support

Hi There,

As i see you have been further improved this plug-in with JAVA EE support, that is good news.

But as i asked before, as three times, is there any plan on integrating NB Platform support(module system) ?

Thanks...
Posted by aligokalppeker on Dec 20, 2014
  

Further development ideas

I use NB almost daily and found your Jacocoverage plugin some time ago. It's a great plugin! I have used Jacocoverage lately a lot and I like it very much, it is very useful plugin, but adding these proposed features would increase its value even more.

1) Add support for running single test file with Jacocoverage
Now it is possible to do "Run With Jacocoverage" and "Test with Jacocoverage" and "Reset coverage data" when you hit 2. mouse button on top of your project.
Currently it is not possible to run single test file with Jacocoverage.
Can you add "Test file with Jacocoverage" command to popupmenu opening when hitting 2. mouse button on top of a single java test file?
In large project it is a great benefit if you can run a single test file instead of all files for updating your coverage data. Running all files might take too long time.

2) Reset coverage data only when user hits "Reset coverage data".
Now it seems that every time I hit "Run With Jacocoverage" the existing coverage data is deleted/reset.
It would be more usefull if user could do several "manual" test runs (i.e. "Run with Jacocoverage) and also run JUnit tests and all these tests (manual and JUnit tests)
were included into coverage data until user hits again "Reset coverage data".

3) Add support for depending projects / libraries.
Suppose that I have developed three libraries (lib A, lib B and lib C) and an application D. Lib A is called from lib B and application uses libs B and C.
Suppose also that I have JUnit tests for libs A, B, C and application D. Now I want to measure test coverage for application D and all the code it uses.
Currently it seems that only thing I can do is to run jacocoverages for lib A, lib B, lib C and application D.
These reports miss following coverages:
- lib A test coverage that is exectued when lib B calls lib A during lib B JUnit tests
- lib B test coverage that is exectued when application D calls lib B during application D JUnit tests
- lib C test coverage that is exectued when application D calls lib C during application D JUnit tests
- lib A test coverage that is exectued when application D calls lib B which calls lib A during application D JUnit tests
In my opinion, application D test coverage report should also include test coverages of all libraries it uses.

I hope that you can further develop these ideas into Jacocoverage very soon. I guess that atleast features 1) and 2) should be easy to implement, 3) might take more time.
Do you find these proposal useful / implementable and if yes when could we have them?


I have one problem with Jacocoverage. One of my java test files cause Java heap space java.lang.OutOfMemoryError every time I run it with "Test with Jacocoverage". Without Jacocoverage tests run OK. I have tried to modify project.properties by adding test.run.args=-Xms128m -Xmx2500m there but it does not help. Do you know what to do in this case?

I use NB8 and project builds are based on Ant.

Thank you for your help.

Re: NB Module support

NB platform support is under development, but I can't provide any schedule. I progress (very) slowly, due to a lack of free time. I may release a version this year, or later, I don't know.
Thx for your understanding.
PS: any contribution is welcome ;)


You can try to develop your NB platform project with Maven instead of Ant. NetBeans 8.0 already provides code coverage for Maven projects. Check http://wiki.netbeans.org/MavenCodeCoverage for details (you can choose Cobertura or JaCoCo, look at the end of this webpage). It works fine with Java SE and Java Web/EE Maven projects. I guess it will work with any kind of Maven project, including NB Platform projects.

NB Module support

Is there any plan for supporting NB platform ?

In previous messages i have asked about NB platform support, and you said that it is in progress.

Is there any plan to support it,

I constantly asking about it, because actually we are desperate about finding a plug-in that can measure coverage of NB platform projects.

Thanks...

Re:

I am able to right click on the project and see "Run with JaCoCoverage" and "Test with JaCoCoverage". Neither seem to have any affect for me either. The .jacocoverage directory exists in the root of my project, but is empty.

Re: Plugin does nothing

> Please use the JaCoCoverage action menu

OK, I've been through all the pull-down menus at the top of NetBeans (File, Edit, View ... etc).

I have also tried pulling down context menus by right-clicking in the projects window, on
1. The project
2. "Source Packages"
3. My source package
4. My source class
5. "Test packages"
6. My test package
7. My test class

None of these menus contains a JaCoCoverage action menu.

I have repeated all of the above steps in three projects: one Ant, one Maven and one Gradle.
In all three cases the result is the same - there is no visible way to invoke JaCoCoverage.

Where _exactly_ is the JaCoCoverage action menu?

Re: Re: Plugin does nothing

Hi,
The Alt+F6 shortcut doesn't launch Jacoco.
Please use the JaCoCoverage action menu to launch tests with coverage ;)
Posted by ent38 on May 05, 2014
  

Re: Plugin does nothing

I launch my tests by pressing Alt-F6, and it works in that my tests are run and I get a green bar.
I looked at the link you (ent38) provided, and the Options->Java->JaCoCoverage tab appears, just as shown there.
There is no coverage highlighting on my source code, no textual coverage report, and I can't see any new actions in the menus.

Hi,

Thanks for your answer, actually my primary interest is support of Netbeans Module System( aka Netbeans Platform )

Maven is the another part of it.

Thanks again,

Re: Plugin does nothing

Hi,
How to you launch tests? The plugin adds new actions to run test (or simply run the program) with code coverage.

Plugin does nothing

I have an ant-based JavaSE application created in NetBeans 8.0. I also have JUnit tests covering most of my code.

I installed the TikiOne JaCoCoverage plugin, version 1.3.4.20140322.1836 from the NetBeans plugin portal. I got no error messages, and according to the NetBeans Plugins->Installed tab, the plugin was installed.

Unfortunately the plugin had no discernible effect on NetBeans. The editor colouring was unchanged, and the JaCoCoverage menu items illustrated above were nowhere to be seen.

-------------------------------------------
Part II

I then uninstalled the plugin portal version of the plugin, and installed instead the four nbms from the 8.0 zip on this page.

Same as above - the plugin simply does nothing at all.

Clearly I've missed some vital step, but from reading the documentation, I've no idea what.

Any tips?

Thanks for your efforts

I appreciate your help on netbeans users, and contributions on netbeans code coverage issues.

This plug-in is very helpful on coverage and with better NB module&Maven support it will be great.

Thanks...

Please be patient ;)

Hi,
I'll try to commit big changes asap.
Unfortunately, I can't provide any ETA: I work on this project on my free time only, and I am currently very busy.
Thx for your understanding.

Any new release for NB7 Platform+Maven+JDK7 support

We are waiting a long time for this support. It is promised in 1.4 release. Is there any progress or ETA on this release?

Re: Maven support?

Hi,
Yes, Maven support will be added asap (I am also using it everyday).
I am currently working on Java EE support and NetBeans Modules support. I'll probably start the development of Maven support when the Java EE part is okay.

Maven support?

Hi Jonnathan:
Excellent job; the "good ol' Code Coverage" was devouring one of my cores whenever I tried to check the coverage. The thing is, here at work we all use Maven projects. Is there a plan to add support for it? There are lots of Maven users that will benefit of it. I can help you to test it if you need, or even provide a patch or two on the weekends.
Posted by alied on Oct 09, 2013
  

just what the doctor ordered

This plugin was the missing peace if the puzzle.
Now we can move to java7 completely, because we want our
students to test and measure testcoverage in their prime language.
Good job.

Re: Small problem

Hi,
this is a temporary problem.
Version 1.2.0 may be validated soon. It contains 4 NBM modules. Previous version is 1.1.1 and contains 3 NBM modules.
There is a bug in the PluginPortal infrastructure: it tries to publish the 3 updated modules from 1.1.1, but the 4th module from 1.2.0 is missing.
This issue will be automatically fixed with 1.2.0 validation.

Also, you have two solutions to install JaCoCoverage:
- download the plugin manually
- register the TikiOne JaCoCoverage update center into NetBeans (https://github.com/jonathanlermitage/tikione-jacocoverage/blob/master/README.md#download-stable-and-dev-builds): http://jacocoverage.tikione.fr/nbuc/updates.xml

Small problem

I have a problem to install plugin inside Netbeans ("Available plugins" tab) - some libs are missed so it don't work "out of the box", but from this page it is installed successful.
