Thanks for the quick feedback, Nathen!
As for the orangish color, I'm just bridging IDEA's unit test framework to Force.com's Tooling API. That's the standard presentation for tests reported as failed. Given how configurable IDEA is, I thought perhaps there might be a way to change this from Settings, but I'm not seeing anything obvious.
As for seeing generated logs, I'm assuming you're already selecting that in the run configuration and setting log levels as appropriate. Once that's done, it should display the logs for each executed test method in its results console (with rollup at the class/suite and run level). However, I'm finding that even though I set a trace flag for the test classes, sometimes I don't get back an apex log ID in the results. If I go into the Developer Console (which is precisely what I'm trying to keep anyone from having to do!) and actually observe things, the logs start generating properly and showing in Illuminated Cloud. Needless to say, not what I'm wanting. There must be something I'm missing. I was going to follow up with my contacts at Salesforce today and see if they can share any thoughts on why this would be happening.
Agreed on instructions. I plan to create another short video showing how to get this going and what all it can do. Just didn't have time to do so over the weekend or last night. Expect that in the next day or two.
As for the convenience shortcuts, totally agreed. I plan to model this after IDEA's Java unit test functionality where you can right-click on a test method and run just that method, a test class and run all of its methods, or a node in the Project view and run all tests under that node. It would create a run configuration for you based on the selection and present that first, then run the config.
And yes, once I knock out some of these small-ish things (vs. getting this going at all!), I plan to move on to code coverage. That one might be a little tricky because of how I support IDEA 12, 13, and 14. Evidently code coverage will only work in IDEA 12 and 13 Ultimate Edition but in IDEA 14+ Community Edition, so I'm sure there's some wonky conditional stuff I'll have to do to support my full test matrix.
Again, thanks for the quick feedback!
