Often when we make a change to some code, if it is not properly designed, the result is that cascading changes need to be done throughout the application because bugs will ripple through the system. That's one of the ideas behind why we want to have low coupling between classes. We also have unit testing to combat the effects of this, but let's just suppose we haven't written any, and haven't used
JUnit Factory to create regression tests.
Given that there is a lot of code out there that isn't quite perfect, wouldn't it be nice to have a tool that could analyze changes and where they would affect other code? I can imagine how such a tool might work, but I haven't heard of one before now (that I recall, anyway).
So the point of it all: I heard something about BMC and IBM teaming up on such a tool (my understanding is that BMC started it, and IBM later joined the project). I'm assuming it'd be in Java, but does anyone have information on this? Can anyone confirm or deny the story I heard?
