What is the default output filename pattern?

[Spenhouet]

We only set the output path to test-reports but we also generate other files into this folder (like the coverage report).
We now want to parse only the test reports.
I searched for how the file name is constructed in the code, but could not find it. It's also not mentioned in the README.

I generate a report an get something like TEST-MyTestCase-20230104183332.xml.
So am I right to assume that TEST- is always used as prefix? So the right pattern would be ./test-reports/TEST-*.xml?
