Quote of the day

sonyram — Fri, 29 Jan 2010 20:01:00 GMT

There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult. -- C.A.R. Hoare

Branching and looping in a declarative web test

sonyram — Tue, 12 Jan 2010 15:09:00 GMT

Ever wondered how to do the branching and looping in a web test. Until VS 2008, this is possible only by creating coded web tests and work through your logic
But with VS 2010, it comes out of the box as Chirs explains.

Run tests without VS IDE

sonyram — Wed, 30 Dec 2009 14:17:00 GMT

I have been working on a new build process using TFS 2008 and VS 2008 and were setting up a new build server and were researching whether I could run web tests in the build PC as part of build verification test without installing the Visual Studio test edition. Looks like it is possible with VS 2010 and all you need is VS Team Agent which is a lightweight component running on your build server.

Here is the article, clearly explaining how to go about it.

@@IDENTITY vs SCOPE_IDENTITY()

sonyram — Mon, 28 Dec 2009 21:48:00 GMT

Have you ever wondered why the @@IDENTITY is not returning the "right" value occassionally when everything was working correctly earlier. Here is the reason.

@@IDENTITY and SCOPE_IDENTITY return the last identity value generated in any table in the current session. However, SCOPE_IDENTITY returns the value only within the current scope; @@IDENTITY is not limited to a specific scope.

I like this comment

"This is so true. One of my favorite cartoons (don't know where I first saw it) is of a guy crawling around under a streetlight looking for something. Someone stops to help, and after looking for a while asks "where did you lose it?"

"Over there" he points to a dark corner

"Why are we looking for it here?"

"Because the light is better!"

TFS 2010 key changes

sonyram — Wed, 23 Dec 2009 19:53:00 GMT

Brain has done a wonderful job on creating a blog on the key developments/architectural changes in TFS 2010. Worth reading. Even better the comment section (though it is real long!!). I was hoping for branched history for a given file in TFS 2010 but it looks like it is still missing. I guess we have to live with Power tools until it comes out:(
