When a test class is missing a category, you might see an error such as:

[ERROR] Test mechanism  Time elapsed: 0.305 s  <<< ERROR!
java.lang.ArrayIndexOutOfBoundsException: 0[ERROR] Test mechanism  Time elapsed: 0.102 s  <<< ERROR!

You have to dig into the dump file to find out the actual error was:
