Code Digger analyzes possible execution paths through your .NET code. The result is a table where each row shows a unique behavior of your code. The table helps you understand the behavior of the code, and it may also uncover hidden bugs.

Worked as shown in the dumb sample code, but when I tried it on some real code, it didn't show any results at all. The status bar at the bottom of the Inputs/Outputs window says "Pex: finished" but nothing is shown.
Shame, it looked useful, but if it can't handle real code, it's a waste of time.
Great for simple algorithms. But it seems to give up too early on complex ones. I've been trying to get it to "discover" the perfect bowling game by asserting that score < 300, and so far it hasn't found it.
I have found this tool very useful - generating cases I would not have thought of and obscure conditions that would potentially stop the application - I can now account for these conditions in error handling
I am very pleased as this will increase the robustness of my application - although it goes out of bounds regularly but I'm not sure if thats a problem with the code i'm testing
Just installed this extension, and ran it on a few methods in my code. In every case, it didn't show any results at all. The status bar at the bottom of the Inputs/Outputs window says "Pex: finished" but nothing is shown.
Don't know if it's relevant, but the title bar of the panel says "Inputs/Outputs - stopped" even though I never stopped it. I set it running and waited.
I tried this on a couple of methods in a business logic layer, and also on ones in an MVC controller. Same (lack of) results in all cases.
Shame, this looked like a useful tool, but it doesn't seem to do anything on real code.
I want to take this opportunity to mention that this functionality now ships as "Smart Unit Tests" starting with the Visual Studio 2015 Preview.

Thank you for your continued support.
CodeDigger is a great tool and we like to use it in production! But I think I encountered some problems. Especially with constructors. It seems, that CodeDigger does not instantiate a class by all available constructors. Sometimes it seems, that CodeDigger does not used the standard ctor as well. Is that correct?
Further, sometimes CodeDigger does not generate any outputs! What does that mean?
If you like I can send some code examples to show the problem with ctors or something else and I hope you can answer my question!
Thanks a lot in advance and best regards from Berlin!
I have to mention, that we use Fody for aspect-oriented programming. When I weave the NullGuard into the project, every output from CodeDigger disappears.
But the question about the ctors is still valid! :)
Thanks a lot!
