Test failure with the Eclipse Junit 5 bulk launcher

[vgjosse]

Hello,

I recently migrate some projects from Junit 4 to Junit 5 and I now have test failures linked to Jmockit.
My settings:

• Jmockit 1.49.4
• Open Jdk 11.0.17+8
• MyEclipse 2022-1-0a

When I launch the tests via Maven, it works.
When I launch the tests in Eclipse one by one, it works.
When I launch the tests in Eclipse in bulk, it fails.

The issue is linked to the ArgumentCapturing.varIndexToTypeDesc static map.
varIndex is not unique in the Eclipse bulk launch and the value stored in the map, before the test launch, is overrided.
Which is an issue, because during the test execution, in CaptureMatcher.matches(), expectedType.isInstance(argValue) is false and the value is not captured.

Below is a simple example I made to reproduce the issue.
https://github.com/vgjosse/jmockit-dummy-test

I tried to understand what the varIndex variable is .. but I was not able :(
What I understand is that it is not unique when I launch my tests in Eclipse, in bulk, with Junit5.

Let me know if you need more information.

Thanks a lot for supporting that project.

Vincent

@vgjosse Thanks for putting a sample project together. I'll try to look this over this coming weekend.

@vgjosse Haven't looked yet but did want to confirm, you do have the jmockit agent installed in your MyEclipse correct? If not, install that as it should solve the issue. Update site is https://bisonschweizag.github.io/jmockit-plugin/updatesite

Hi,

I've just made the test with the eclipse plugin you've mentionned and it is still not working.
I made a try with all the 'Check scope' available.

Thanks for you answer.
