Macro to aid BDD test naming style

During the DevTeach seminar that occured in Montreal in May I got an awesome opportunity to pair deliver a TDD workshop with Scott Bellware. One of the things he got me hooked on was using natural sentences as a test naming convention. So instead of this:


You write it out like this:

Should be able to transfer funds between accounts.

Of course, only one of these is legitimate from a compilation perspective. So Scott had written a macro that would replace all of the spaces in the test name with underscore. You invoked it by highlighting the name of the test and hitting a key combination that was bound to the macro. Which would convert the natural sentence to the following:


During the last course, Terry Hughes improved upon the macro so that now all I have to do is type out the name of the test and hit ALT + _ (that is what I have the macro bound to). I don't need to select the name of the test.

It is a subtle change, but one that allows me to just write out the name of my test without worrying about camel casing or underscores.

Here is the macro:
