I was looking at those code contracts with great interest. I do quite a number of asserts in my base code, but those aren't all that "official". Code contracts were the one reason I looked at Eiffel with a great deal of envy back in the day :)
Code contracts - however implemented - are great for negative testing. I had been thinking of things in terms of separate tools, but perhaps classes is a better approach for some parts. I don't suppose Microsoft might have any particular libraries that could represent a whole file system, does it? For some peoples' odd DMZ requirements, I put together a VirtualFileSystem a little while back - you could attach a memory-based file directory root to '/$(user)/inbox' and anything using that directory or 'below' would be dealing in memory-based files, but it wouldn't be robust or transparent enough for the needs I am imagining. It just might be nifty to have tools be able to deal with real directories when appropriate, or use something virtual when combining tool classes together, or use a repository directly for some uses, or use something totally fake when unit testing, and be able to dump out files from a virtual tree to a real drive when dealing with third-party tools. In some ways, it's not all that hard to put something like that together, but it might be too majorly highfalutin' for our purposes here :) -- Ritchie ----- Original Message ----- From: Jonathan Ben-Joseph <[email protected]> Date: Wednesday, April 21, 2010 11:47 am Subject: Re: [Coapp-developers] Thinking abotu testing CoApp's tools.
