    Does anyone know of a good book or website that goes it strategies for (unit) testing legacy code that wasn't designed with testing in mind, such a no DI seams.

    Language is C# if that makes a difference.

    Being 10 years old doesn't matter ? The principles still hold up ?

    Nope! That book more than anything else, helped me getting a particularly... troublesome module under some sort of control.

    In fact I started a thread kinda like this a year ago you should check out - http://www.boards.ie/vbulletin/showthread.php?p=87011342

    Have I dreamed these up ?

    Are there such things as AutoMocks, where their functionality would be to mark code for mimic, record interaction on the first play through and mimic it back when under test ?

    It's more than possible that I have made this up :) But If I haven't it needs to be developed. Google hasn't shown me anything, but I don't really know what I'm searching for :)

    C# = legacy code :-)

    I'm almost afraid to ask this question for fear of feeding a troll; but what exactly isn't legacy code then if C# is considered legacy code?

    From Wikipedia page on Legacy code
    ...source code inherited from someone else and source code inherited from an older version of the software.

    Alternatively, legacy code is code you've inherited from someone else which doesn't fit with the latest techniques, or with the fad-du-jour in that particular programming language or genre.

    I can assure you this code is legacy code, you too would agree if you saw it.

    Lol. I'd say that legacy code, is any code that is not under any kind of test... Now why can't we just all get along? :)

    But the Open Source Selenium project does this for webapps
