Unit Testing with TestDriven.Net

I downloaded TestDriven.Net a free tool that integrates with Visual Studio to make Unit Testing easier. You have to register and there is a survey to take before you can download.

After installing the add-in I added my test class to the project. Previously I had been keeping it separate. I also added a reference to nunit.framework.dll in the project. After this I right clicked on the TestCalculator.cs file in the Solution Explorer and chose Run Test(s). It ran immediately and 0.11 seconds later the results were ready...

------ Test started: Assembly: calc.exe ------
18 succeeded, 0 failed, 0 skipped, took 0.11 seconds.
---------------------- Done ----------------------

But alas, no green bar! The output is just not as pretty. Well I suppose that would be difficult to do.

Then I made one of the tests fail by asserting that it would get the wrong value. Again the output was not as pretty as in NUnit.

------ Test started: Assembly: calc.exe ------
TestCase 'NUnitTest.TestClass.DisplayInitialisesToZero' failed:
String lengths differ. Expected length=2, but was length=1.
Strings differ at index 1.
expected:<"01">
but was:<"0">
------------^
d:\source\c#\calc\calc\testcalculator.cs(25,0):
at NUnitTest.TestClass.DisplayInitialisesToZero()

17 succeeded, 1 failed, 0 skipped, took 0.12 seconds.
---------------------- Done ----------------------

This gives you exactly the same information you'd get in the NUnit GUI, except there is no red/green bar. It would be nice if the output was more graphical, but even so, it is much better to have the tests running inside Visual Studio.

Other things

Lots of people are talking about things that are mostly not .NET...

Ruby on Rails which is an open source web framework

And Google maps which is now available in the UK.

And there is even a .NET wrapper .dll for AJAX
