Phpunit errors

I had finally got phpunit working and running a few tests... But I moved an objects creation to the setup and bam got errors. Since then I have cascaded down to a bin of pain.

Originally when I moved my objects creation to the setup method I got class hash not found. I tinkered around and got undefined index. I ran cache:config I believe when everything seemed to get hopeless.

Basically all my tests went from working to all erroring.

The error is referencing a migration which does not exist. I moved my migrations earlier today and regenerated them which is originally what got my tests working because sqlite was throwing errors that mysql didnt.

I don't really know what code to show because the tests are exactly the same as they were when I was getting green earlier. There seems to be some sort of error coming from my migrations again but I don't really know what to lookup or where to look.... any advice?

the exact error reads

ErrorException: Undefined Index: (invalid date/nonexistent file)MIGRATiON NAME

Edit: if you end up here looking for a potential source for the class hash not found error, what happened was when i added a setUp method I forgot to pass in the parent setup method. I think this was the main source of all my problems because when trying to fix that my problems cascaded down and took a while to fix so hopefully that helps someone
