i have got a new functionality in my code. How to test?

Hi there;

i have got a new functionality in my code written in C# which is a huge project. How to test?
Is there any formal ways/techniques/templates for such testing.

U can do either manually or using nUnit testing depending on the functionality you have

Manually would be easy, if that's a huge project:

Just add breakpoint where the new functionality starts and Breakpoint at the very last line of this new functionality. step into code by pressing f11 to see step by step execution and  values your variables maybe fetching.
there after you can see if the results match the web-display results.

Hope that makes sense!

Cheers!

>>nUnit
Is it supported by C#, VS 2010? How? An exampel?


>>web-display results.
it's a standalone.

These are two different types of questions. NUnit is used for unit tests, i.e. testing of individual methods/properties.

By the way, nUnit tests can be written in C# VS does not support them, I believe, they use different framework. However you may write and run unit tests in a NUnit UI application. And you may attach test code to a debugger in VS (just attach a nUnit UI process to VS)

Hand testing will test functionality of your application. This is most used testing. How to test - different story. You need to follow some use cases. You just follow some sequence to enter, for example, user's data to a form etc. Also you need to test "faulty" scenarios, for example if a user enters 1111 year as his birthday, or non valid card number etc, or enters alphabet characters into a number field. In this case you test that the application does not crash but respond gracefully with appropriate messages etc.

There are tools for automated UI testing but even you caqn find (or buy ) some you need to write tests for these tools.

followed the links:

http://www.dotnetfunda.com/articles/article707-5-simple-steps-to-execute-unit-testing-using-nunit-.aspx

to clarify:

I downloaded nunit
http://nunit.org/index.php?p=download

I followed the explanation in the links, creating the template, then creating test case but failed to run the test as follows in Nunit downloaded above. Simply, it says unknown framework, even I change it to v4.

Kind regards.
