The Process class allows you to redirect the three streams basic I/O streams of a process: standard input, standard output and standard error. This is particularly useful for programmatically running console applications and capturing their output. And...

A while ago I wrote about using reflection for testing non-public members . Since then I've been increasingly annoyed by the repetitive nature of that approach. At some point it occurred to me that it should be possible to automate the mundane and boring...

I find myself getting more and more frustrated whenever I see test code that is best described as quick and dirty. Now, sometimes I do acknowledge that the world is not perfect (has never been and will never be) so I realize that the following is really...

I'd like to share my colors with you: R G B Coverage Not Touched Area 230 128 165 Coverage Partially Touched Area 191 210 249 Coverage Touched Area ...

It's been a couple of months since I first blogged about EMTF . Since then I've been busy refining and extending the framework and I'm happy to announce that the beta release of version 2.0 is finally done! Special thanks to Josh Poley since a lot of...

When you're searching binging for how to add or remove websites to/from IE's security zones you'll find tons of samples all showing how to achieve this by creating and deleting registry keys. While doing so will probably work just fine in most scenarios...

Many posts have been written about how to debug problems with issuing HTTP requests from Silverlight applications, particularly in the context of web services and WCF (see for example Debugging Web Service Usage in Silverlight 2 or Faults and Exceptions...

The Portland Code Camp yesterday was a blast. In fact, it was one of the best (un)conferences I've been to so far with a wide variety of topics and I'd like to share my personal Top 3 Best of Portland Code Camp 2009 (but keep in mind that that's 3 out...

Writing a fully featured API testing solution is a lot of work. You have to deal with things like test case management, integration with code coverage tools or test execution on server farms. However, the core of a (reflection-based) API testing framework...

A while ago a needed to do what I like to call quick and dirty testing , i.e. getting as much test coverage as possible in a given period of time. To make things worse, I was working on a client-server feature requiring a bit of setup in order to work...

A while ago I published a post titled Pimp your VSTT exception tests in which I pointed out some disadvantages of VSTT's declarative approach to testing for exceptions and provided an alternative. I recently gave this some more thought while writing some...

Earlier this year I bought a brand new computer and wanted to play what turned out to be one of my favorite games of all times. However, it also turned out that this new computer of mine came with a pretty bad graphics card. It did work but the performance...

Don't make any plans for March 18-20 next year (or cancel the plans you've already made) since that's when MIX will happen once again in Las Vegas. The MIX09 website is already online and if you liked what we showed you this year you will love the cool...

I have to admit something embarrassing: I've never been to a code camp! So, I thought, before people start making fun of me because of this, I'd better sign up for the Seattle Code Camp v4.0 which will be held on the third weekend next month in... Redmond...

I have to admit the title is a bit misleading this time since - if you ask me - there is only one answer: Hyper-V ! It is the first Microsoft virtualization product to support 64-bit guest operating systems, SMP for some guests (see Supported Guest Operating...

Say you are working on software that accesses a database server and you need to test it. To some extent you'll probably try to not actually hit the database with your tests by using a mock. However, this is not always possible, especially when we're dealing...

Writing unit tests in VSTT is great since it comes with a nice unit testing framework and the test tools are neatly integrated into Visual Studio. There is one exception though: Exception testing (yes, that pun was intended). Consider the following example...

Let's say you want to unit test the following class: using System; internal class Foo { internal Foo( object parameter) { if (parameter == null ) throw new ArgumentException (); } internal int ReturnZero() { return...

Introduction I spent some time this week thinking about how to test a code generator that generates C# code and is itself written in C# (so it's once again all about managed code). At first I thought about how to verify the generator output directly...

Compiling code at runtime is incredibly easy thanks to the CSharpCodeProvider class. But as always, there is a catch. Let's say you have the following code snippet somewhere in your shiny new VC# 2008 project: CSharpCodeProvider codeProvider = new...

While Microsoft is certainly not an open source company there are some instances of code drops from, and open source projects started by teams at Microsoft that are released under licenses which comply with the definition of open source as defined by...

One of the outstanding sessions I attended was What's the secret Formula? (PNL14) . The panelists were (in alphabetical order): Dan Harrelson - Senior Technologist, Adaptive Path LLC Daniel Makoski - Microsoft Corporation Jensen Harris - Principal Group...

If you read my Silverlight-based P2P live streaming client wins MediaGuardian Innovation Award post you might say that this is getting old but at the same time I really think it's worth mentioning that there is a product and a partnership involving Silverlight...

This is the first on an n part post series about my personal thoughts on this year's MIX based on notes I took during the conference (and, no, I don't know the value of n yet). Let's start with the keynote on the first day which was a great kickoff with...
