When I run tuneup_js from the command line and include the xunit output I receive this error about tuneup_js

I've been encountering the same issue and I did a bit of digging into it. What appears to be happening is that the add_status method appends a status to the suite.test_cases array by going to the last element and changing it (to pass, fail, or some other status with a message). It is expecting the last element in the array to be a new TestCase object created when the add_status method last encountered a "start" status. If however, the first status your script throws is not "start" (but say "debug" as is the case in mine), the suite.test_cases array will be empty, and add_status will attempt to access the .last element of the empty array, which will then lead to the NoMethodError, because there's no TestCase object being accessed.

How best to go about fixing this is probably above my paygrade, but hopefully this information can help someone else.

Thanks this helps! The solution I am currently using is to ensure I start the UIAutomation with a test case. This sort of solves the problem

FWIW, I've been using Bwoken instead of tuneup's test runner. It's much more robust so I would suggest taking a look at that.
