A couple weeks back, Ron Jeffries was playing with VisualWorks and I got him playing with SUnitToo/ExtraRBForSUnitToo. One of the things he talked about was the "two browser" approach, having one browser open for your test case and another for your testee.
At the same time, we were having a discussion about how unique Key Tech is in putting Tests right along side the classes, in the same package. For us, what this means, is that we can switch back and forth between a testee and its test case pretty quick. They're almost always right there together. For various reasons, not everyone else is in a position to do as we have done, and one loss there is the extra navigation to go back and forth between the two.
Some of our guys use RBTabs and will have one buffer open for the test case and the other for the testee. This type of approach would be handy for those who don't put their test cases by the testees.
Then I had a little light bulb experience. What if you could manage that with a shortcut key? Here's the mindset. I'm working on a testee. For reasons sundry, I decide I need to look at the testcase, but I don't want to keep navigating. I'd like to have a new buffer for it. Or if I have a buffer for it already, then just switch to that one. And the converse of course. So, there's no an ALT-T shortcut with the latest version (1) of ExtraRBForSUnitToo (the tool counterpart for SUnitToo). I played with it for just a few minutes and found I really liked it. I don't have to memorize that the test is in buffer 1 and the testee is in buffer 2 so that I can use the alt-number shortcuts. And it creates them as I need them. Let me know what you think. It should work fine even if you are using RBTabs.
BTW, if you read through this thinking "what's a buffer?", I'd like to know. Technically, they're called "Views" in the VW IDE, and I guess I could've used that term.
