I'm building some junit tests for one of my projects in MyEclipse 8.6.

Is it possible to have the project/junit code create an XML output file that holds the test results?

davout,

JUnit does not have any native XML output format. The format you're
discussing is supplied by Ant. You can use the Ant xml formatter. Take a look at sections 4.6 and 4.7 of this tutorial on how to write JUnit test results to XML files:

I also suggest you crosspost it to JUnit forums for better support.

Hope this helps.
