C# Coding Tests

Posted By:      Posted Date: October 25, 2010    Points: 0   Category :ASP.Net


I'm currently preparing for interviews (NOT looking for interview questions) and would like to go over some of those little coding tests they can throw at you in some interviews (Like "Create a program that calculate the Fibonacci for a given number")

Does anyone know a website where there are tests like these listed?

It's not that I have problems with my C#, it's just I get thrown off track easily with test like these thrown out of the blue at me, without being able to look up some code, refer to my old code, have resharper hold my hand, etc.  (Sounds stupid I know :-) )

The void is invariant

while back I described a kind of variance that we've supported since C# 2.0. When assigning a method group to a delegate type, such that both the selected method and the delegate target agree that their return type is a reference type, then the conversion is allowed to be covariant. That is, you can say:

Performance Tests: Precise Run Time Measurements with System.Diagnostics.Stopwatch

Everybody who does performance optimization stumbles sooner or later over the Stopwatch class in the System.Diagnostics namespace. And everybody has noticed that the measurements of the same function on the same computer can differ 25% -30% in run time. This article shows how single threaded test programs must be designed to get an accuracy of 0.1% - 0.2% out of the Stopwatch class. With this accuracy, algorithms can be tested and compared.

reading values from config files in NUnit tests


One of my NUnit tests has to read in some values from config files.  In my main application this process works perfectly well, however when I run the unit test, the code that reads in the values from the config files doesnt read anything in.  Ive tried putting app.config in my unit test project (I even tried web.config) but nothing seems to work.  Are there any special steps involved when reading from config files in an nunit test ?
