CSVDataLoader#writeOutputData throws NPE when running a single test #2

Closed skuenzli closed 10 years ago

skuenzli commented 10 years ago

CSVDataLoader#writeOutputData (sometimes) throws NPE when running a single test. I think this may only occur when there are multiple parameters being passed-into the test method, but I haven't looked too deeply.

The caused-by stack is:

The issue is reproducible in IntelliJ.
