Most of us are already familiar with the NUnit. I hope we all have written lots and lots of test cases to check our code. Among many attributes of NUnit, one of my favourite is a 'TestCaseAttribute'.
As quoted on Nunit.org "TestCaseAttribute serves the dual purpose of marking a method with parameters as a test method and providing inline data to be used when invoking that method."
This attribute helps us to run few common test on a single go and also helps us to group thest test cases together.
eg.
/// <summary>
///A test for Divide
///</summary>
[TestCase(12, 3, Result = 4)]
[TestCase(12, 2, Result = 6)]
[TestCase(12, 4, Result = 3)]
[TestCase(12, 0, ExpectedException = typeof(System.DivideByZeroException),
TestName = "DivisionByZeroThrowsExceptionType")]
[TestCase(12, 0, ExpectedExceptionName = "System.DivideByZeroException",
TestName = "DivisionByZeroThrowsException")]
public double DivideTest(int x , int y)
{
return Functions.Divide(x, y);
}
I hope we can all use this attribute and use this functionality to make our life lot easier.
