So I had this analogy pop into my head a while back and I’ve been sitting on it because, quite frankly, I was almost embarrassed to have thought of it.  I finally decided that I might as well post it since no one is going to read this anyway, so here goes:

Writing software without TDD is like having unprotected sex.  Its extremely irresponsible in this day and age when everyone is supposed to know better, but it still happens a lot.  Sure, it feels better, and let’s face it in the heat of the moment you really don’t want

 to take the time to make sure you’ve taken all of the right precautions…you might loose your edge.  The problem is if we don’t do it we have that lingering fear in the back of our minds, that “What if?” that keeps popping up at the worst moments.  Most of the time its okay, and everything is fine, but it only takes one time for things to go wrong to make you regret your decisions.

So come on folks, we all know what we should be doing, so no more making excuses.  After a while you get used to it, and you find that the peace of mind it gives you far outweighs the momentary delights of living on the wild side.

I recently decided to take the plunge and get CodeRush and Refactor! Pro (along with DxCore) loaded instead of Resharper.  Now, don’t get me wrong, there is a lot I like about Resharper, but overall the performance was becoming an issue.  There were often problems with VS freezing for no particular reason, and then coming back as if nothing was wrong…I swear it was like my IDE had narcolepsy or something.

One of the things I noticed immediately about CodeRush was the fact that there was a single installer, and when I went to run it I was able to install it on all versions of Visual Studio, including the Orcas Beta.  This was nice when compared to Resharper’s separate install for vs 2005 and vs 2003.  It also makes me feel good about improvements in the product being available for all versions of the IDE.  One thing that I noticed about R# was that there was some work being done in the VS 2005 version around performance, but that did not seem to trickle down to the VS 2003 version.  I think the big reason for this is the fact that CodeRush and Refactor! are implemented on top of DxCore, which provides a very clean abstraction from the scariness that is the Visual Studio integration layer.

Here are the things I really like about CodeRush/Refactor:

  • The visualizations are stunning!  No, seriously this is some amazing stuff.  Circles, arrows, animations, eye candy yes, but useful eye candy.
  • The Refactoring Live Preview is crazy brilliant.  Mark Miller mentioned this on a DNR episode, and I agree with his comment that the live preview allows you to discover new useful refactorings that may not be completely obvious from the name.
  • Performance is great.  ‘Nuf said.
  • It works with VB.Net.  Granted I don’t use VB.Net, but some of my co-workers do, and occasionally I have to work on VB.Net projects.
  • Dynamic Templates rock.  The fact that I can create a new mnemonic for my type, and then use predefined prefixes and do vee<space> to create a new Employee Entity for example is pure bliss.
  • Template contexts are way cool.  By default they have NUnit templates defined, and with contexts, t<space> creates both a TestFixture class and a Test method
  • Markers and navigation are dreamy.
  • There are some crazy-cool template functions, like the ability to do a foreach within a template, so things like creating a switch/case statement for all items in an enum can be done easily.  This also powers a conditional to case refactoring that is pretty sweet.

Here are the things that I miss from Resharper:

  • Automatically adding a using statement in VS 2003 was sweet.  VS 2005 can do it with the buit-in intellisense features, but I got very used to it.
  • The VS 2003 test runner was very nice.  I use the Testdriven.Net plugin, which I cannot live without, but I like the graphical runner in the IDE.  The free test runner from JetBrains is for VS 2005 only, so it doesn’t help those of us in VS 2003.  I do like the fact that they released it as a free tool, though.
  • The “Extract Field” refactoring doesn’t exist in Refactor!…This shocked me a lot.
  • The Find Usages task.  This I think is part of the reason why R# was slow, but it did a brilliant job.  I think the rename in R# was more powerful as well.  I think there is a rename in Beta for Refactor! that is supposed to be able to work accross an entire project/solution, but I haven’t had a chance to really test it yet.
  • The pre-build error checking is nice.

The good news is that the DxCore extensibility model means that most if not all of these items could be recreated.  The bad news is that there isn’t a lot of documentation around the extensibility model, particularly when it comes to creating new refactorings.  The test runner is one of the most painful points for me right now, so I’ve started exploring the process of creating one using the DxCore APIs.  It opens up the possibility of refining things too, which would be nice.  What I would really like would be the ability to detect and integrate with TestDriven.Net.

The folks over at Eleutian are evidently running both, which they claim is possible with some tweaking, but the performance issues for VS 2003 are the biggest downer on the R# side, so I will probably not go down that path.  I may load up the test runner for VS 2005, unless I get some time to try and build one using DxCore, in which case I’ll share it with the rest of the world.
