Expected: Test name for published test results to always match content of <rootPath>.
Actual: When job contains more than one FitNesse test results published then test name appears as "Summary".
Steps to reproduce:
Given you have two test suites: TestSuite1 and TestSuite2
In a single job run TestSuite1 and produce TestSuite1.xml
Run TestSuite2 and produce TestSuite2.xml
Publish FitNesse tests using *.xml as a mask
Upon execution FitNesse test results (and test history) will contain Summary as test name.
P.S. Same would occur if you use copy artifacts plugin to collect all FitNesse XML files into a single job and publish them simultaneously.
