I was encountering “permspace” “Out.Of.Memory” errors, and I believe it’s because of a memory leak with the UI/Java. In any case, this worked for me:
1. Create a text file with the test suite names — will automate this soon by “capturing” the names from the XML project file.
2. Loop through it via the terminal:
while read i; do testrunner -s"$i" -R"TestSuite Report" -FPDF ~/project.xml; done < ../testsuites.txt
