Problem when trying do gui tests in jenkins

gonr1001gonr1001 · January 19, 2019, 12:53am

I have a small h=java project which uses javaFX, junit5 et gradle, the tests run fine in eplipse, the test run fine using gradle in the local mac, when trying to run the tests in jenkins using the same gradle file tests break when the test using the gui are executed, there are exceptions.

Here is the project

Here are the eclipse project zip

Could you give an example of what kinds of exceptions you were seeing? Could it be because the Jenkins environment doesn’t have a window manager for the GUI to use?

It’s likely that your Jenkins server is headless. You could get the same failure locally by setting

System.setProperty("java.awt.headless", "true")

You will likely want to use TestFX & Monocle for headless testing of JavaFX

Hi Thanks for the Answer

The Jenkins server was updated to the last version, the gradle version indicated is 4.1, in my computer (a Mac) is 5.1.

So I send you the output on Jenkins.

And the files that compose the program, the program intention is to be sur that junit5 test works fine junit tests and testFX tests.

Thanks for your help.

The program works fine in a mac and in a PC, inside eclipse and outside with gradle.

The message from Jenkins is at the end of the mail.

Do you mean that is not possible to run gui tests (testFX) using jenkins?

Ruben

gonr1001gonr1001 · January 24, 2019, 6:29pm

Yes I need to use testFX Monocle can be changed, if you have an alterative.

Lance · January 24, 2019, 9:19pm

Monocle is the implementation of the windowing component of JavaFX (Glass) which will work on a headless server (eg jenkins). I think you’ll need to use Monocle to test JavaFX on your Jenkins server.

A quick read of the Monocle docs discuss
-Dglass.platform=Monocle -Dmonocle.platform=Headless -Dprism.order=sw

I suggest you do some further reading on using Monocle with JavaFX on a headless server
