I come from a Java/Eclipse background and I fear that I am spoiled by how easy it is to get JUnit and JMock running in Eclipse, and have that GUI with the bar and pass/fail information pop up. It just works with no hassle.
I see a lot of great options for testing in C# with Visual Studio. NUnit looks really nice because it contains unit and mock testing all in one. The trouble is, I can't figure out how to get the IDE display my results. The NUnit documentation seems to show that it doesn't automatically show results through the VS IDE. I found http://testdriven.net/, which seems to trumpet that is makes VS display these stats and work with multiple frameworks, but it isn't open source.
Is there anyway to get unit and mock testing working with the VS IDE like it does in Java with Eclipse?
On installing NUnit you get an NUnit.exe - use this to open and run your tests. It has an UI and shows pass/fails and shows output.
You can add a build action in Visual Studio that on a specific testing configuration will build, then immediately invoke NUnit on that dll.
EDIT: (more details)
In test project:
Project Properties -> Debug (set a build configuration - I use "NUnitDebug")
Start Action -> "Start external program": C:\Program Files\NUnit 2.5.3\bin\net-2.0\nunit.exe (use your own path)
Start Options -> Command line arguments: MyTestProject.dll (replace with the name of your DLL)
EDIT2: As brendan said, Moq is a good mock framework that can be used.
Resharper will let you do this and has a nice UI. I believe the core of it is NUnit. For the mock stuff you'll want to use Moq.
Resharper is not free/open source but is so worth the price.
If you are looking for something like Eclipse/JUnit, you shouldn't have tried Microsoft product line.
But the good news is that SharpDevelop has such nice integration with NUnit and it is open source. However, it aims as an alternative to VS, not an addon for VS.
You could read ASP.NET MVC Test Framework Integration Walkthrough and run your tests from the VS test runner.
Have you tried using the Testing projects in Visual studio? They're practically identical to nUnit, and can be run simply by hitting F5.
For mocking, chose whichever suits you, We're looking at Moq for Silverlight support.

I'm new to NUnit and I just download it today and I can't get it working with visual studio. (I'm new to Visual Studio as well)
I'm following TekPub's Mastering C# 4.0 tutorial.
Screenshot: Something is missing within the red circle area. There should be some "green thing" on the side that let you double click on it and run the NUnit test.

As you can see on the above screenshot, the NUnit seems not working....
Did I miss something? Please advice. Thanks
EDIT
This is how it SHOULD look like. I took a screenshot from the video tutorial:
http://dl.dropbox.com/u/20422001/nunit.jpg
and here is the project files:
http://dl.dropbox.com/u/20422001/MasteringCSharp.rar
As you can see, I don't have "Unit Test" Tab and "Unit Test Session"...
You aren't doing anything wrong. Out of the box, NUnit doesn't integrate directly with Visual Studio. The screenshot from the video appears to be using Resharper's test runner.
Typically testing with NUnit requires you to compile your test project and then load it into the NUnit GUI (nunit.exe) where the tests can be run from there. When using the NUnit GUI, the project will reload anytime the assembly is recompiled. (I sometimes prefer having this in a separate process as it doesn't tie up Visual Studio's UI, but that's a matter of preference.)
The added advantage of using a third party test runner like Resharper, TestDriven.net, Galileo, etc is that it allows you to run or debug the tests directly from within the IDE. You can accomplish the same thing using NUnit by configuring Visual Studio to attach to NUnit and debug your tests from the external process. This post shows you how.
I haven't seen that particular video, but it sounds like you need an NUnit test runner for Visual Studio.
Check out the following:
Visual NUnit 2010 - free!
TestDriven.net
ReSharper
That my friend is JetBrains' Resharper - it's a paid add-in to Visual Studio that allows you to run tests from within the IDE. Highly recommended if you're working for a prolonged period in VS.
Of course since you're just starting out, you could use the NUnit GUI to run your tests. You can also set it to run tests after each build.
Tools > Settings > Test Loader > Assembly Reload. Check "Re-Run last tests run". Apply changes
I have looked around SO and the web for quite some time now and I am struggling to find any information for how to setup my C# project for unit tests.
I started on the NUnit main site http://www.nunit.org, the download includes a GUI to run your unit tests, sounds mint. Only when I try and point the GUI to my .exe, I get an error immediately saying that NUnit is not designed to be run with this framework. That got me thinking that maybe NUnit doesn't work with .net 4. Apparently it does, plenty of people online seem to state that they are running NUnit unit tests with .net 4 .... of course they don't seem to go on to say how.
Clicking around google I found what appears to be one of the core members of the NUnit development is a dude called Charlie Poole. I found he had a launchpad here: https://launchpad.net/nunit-xtp. The version numbers are newer than on the main NUnit site. When I downloaded the project however, it is just the codebase and solution for the NUnit framework with no GUI. There is a command line runner included but I really need something visual.
We do have jetbrains teamcity as a BMS so I am now going down the path of maybe trying to integrate NUnit into the build pipeline somehow. If anyone can shed any light on how they got NUnit working with an express edition of c# that would be wonderfully helpful.
Edit : I have the teamcity BMS running the tests now, so that part is no longer a problem. However, waiting for the build each time just to find a NullException error or something doesn't really cut it. I have to get the GUI runner working. I found this question NUnit isn't running Visual Studio 2010 code but even that isn't fixing it for me. The error has now updated to read version v4.0.30319, so the config changes have taken effect. Same old error though :(
Right I sussed it out. there is a very similar question here:
NUnit isn't running Visual Studio 2010 code
Only what it doesn't mention is that there are multiple config files for NUnit. I just assumed it would suffice to edit nunit.exe.config. This did indeed update the settings as I saw it in the error message. However, the nunit gui runner must make use of one of the other multiple .config files. I simply went through them all and added the two required settings.
Make sure that you run the correct .exe. One is called "nunit.exe" and it seems like the correct one to use. The other one is called "nunit-x86.exe" and if your app is 32bit then you have to run this one. If "nunit.exe" was names "nunit64.exe" I think I would have noticed that much sooner.
You must also make sure that you check the version number of the CLR matches the setting you are pasting into those config files. Use this link to work out your current CLR version number. How do I find out what CLR i am using? I am Microsoft Visual C# 2010 Express and my CLR version number is v4.0.30319
The unit tests should be in a seperate assembly (of type class library). If you point NUnit to that assembly, it will run. Same applies to the command line runner (which is normaly used in automated build processes).
The default NUnit distro includes a GUI runner called 'nunit.exe'. If using it, I set my debug target on my test assembly to load the GUI runner with the appropriate config.
If I'm not mistaken, NUnit is the de-facto standard for unit testing, but I've just downloaded it, wrote a simple test, and then apparently I have to fire up the GUI and load my .exe assembly, which simply failed.
I tried editing
C:\Program Files (x86)\NUnit 2.5.7\bin\net-2.0\nunit.exe.config
As suggested in this question, but that didn't work either, so I tried downloading the nunit source code and compiling it in vs2010, but it doesn't even compile. Says punit.framework.dll could not be found. That solution says "does not contain a definition for AllTestsExecuted", so I'm getting a little frustrated here. You'd think there would be an easy-to-use-and-get-running framework for .net 4, no?
So my question is, how do I either get NUnit working, or is there another framework that will cause me less agony?
You don't have to use the NUnit GUI to run your tests. You can use TestDriven.NET from within Visual Studio. Also, if you happen to be using Resharper, that has a unit test runner which works with NUnit also.
If you're not doing anything out of the ordinary, I recommend Microsoft's Unit Testing Framework. I find it's VS integration too easy to even worry about NUnit. I agree NUnit seems to be the defacto standard, but if you're looking for something quick and easy. Microsoft's way is the easiest for a typical Visual Studio programmer IMHO.
I am not a C# programmer (fortunately ;-) ) but I've heard good things about xUnit. Tests can be run pretty much however you want (command line, GUI, Visual Studio integration, and more) and it looks reasonable simple to use.
For NUnit's GUI test runner, make sure you've selected the right framework version. Its in the "File" menu. If your test or any dependencies are 32-bit be sure you're running the 32bit version of the test runner.
Testdriven.net is a better test runner, but I like using NUnit's GUI runner too at times.
NUnit is infact very simple to use, so I would say that it's more likely that you are making a mistake somewhere, not the software.
Make sure you follow this guide.
Ensure that you have the [TestFixture] and [Test] attributes in the correct places and all the relevant assemblies referenced.
Make sure that you are loading the correct dll in the NUnit GUI.
If its the GUI that is the issue, you can use Resharper's unit testing feature in stead.
If you use Visual Studio 2010, you can use MSTest. Just click CTRL + ALT + R and it will run your tests and show the results in Visual Studio itself.
That same test-runner will also work for NUnit, if I am not mistaken.
I am working on a class library (DLL) project in Visual Studio 2008; programming in C#. In order to test my DLL I just created a second project that is a console application and in that project I can reference the first and run tests. Is there a simpler way of doing this? Can I just create another file within my class library project that has the tests in it and then somehow tell Visual Studio to run that file?
I know one way would be to add a text file to my project and then write my test code in JScript. Then in the Project settings on the debug menu I can tell it to Start External Program (JScript). Then, the name of my test file, test.js, goes in the Command Line Arguments box. But, I am wondering if there is a way to do it using C# code instead of JScript?
You could add a testing project to your current solution, then set that project as the startup project. Then, hitting F5 on your class library project will start your testing project.
Take a look at NUnit or other similar unit testing framework.
The "Team Developer" and "Team Suite" flavors of Visual Studio already have Microsoft's unit testing framework built in.
Create a unit test project for the class library by using the right-click "Create Unit Tests" in a class/method in the library. I would recommend downloading TestDriven.NET and using the right-click test runner in it.
Are you talking about unit tests? You can use something like nUnit or the built in testing framework that comes with Visual Studio. The simplest tests just require you to add some attributes to your test fixture and make an assertion like obj1 == obj2.
Checking out something like Test-Driven Development (TDD), Domain-Driven Development (DDD) or Behavioral-Driven Development (BDD) may be beneficial. I like to use nUnit with nBehave, myself.
I'm developing an ASP.NET 2.0 app using Visual Studio 2008.
If I want to run a really quick test on a method that's way in my back-end, is there a way for me to just call a main function in that class via command line?
Thanks
Short answer: NUnit. You may not know how to use it, but you should. It's not hard to use and learn. It's fast and has a GUI.
That's what a test project is made for.
You should get TestDriven.NET add-in (free for personal use). Basically, it's a bundle of Test Driven Development tools such as NUnit, which integrates with your Visual Studio. One thing I discovered about it, is that it allows you to run any method in your code, just by right-clicking on it and choosing the menu item "Run Test(s)", or "Test With -> Debugger" if you want to debug the method.
Hope that helps.
The answer is no, You cannot do that. You can only have one main function per assembly.
The fact is, you shouldn't do testing like that. C# is not Java, regardless of its origin in Java.
Use NUnit or MSUnit and build unit tests instead. They'll test your methods for you without needing deployment to a website or anything like that. That's the best way to test a method. Here are some links:
NUnit
MSUnit
Simply create a test project and test it from there. If not you can create a console application and test it from there by referencing the proper project(considering your code to test is in an assembly), which in a way will be your test project.
