Dissection of void Methods with parameters
Methods with void return types incur complexities in writing unit tests. So, we need to characterize the void methods to make sure we have guards against the odds for testability.
For example, the following is a void method with parameters
public void DoSomething(SomeType obj, SomeOtherType objOther)
{
//1.modifies some member variables
this.someMemberVariable = 10;
//2.Calls methods of the same class or other classes
someOtherClass.SomeOtherMethod(someArg);
//3.Sometimes throws exception
//4.Modifies call by reference type argument objects
obj.SomeProperty = objOther.GetResultOfSomeAction();
objOther.DeleteSomething();
}
Unit test examples for all the scenarios other than 4 are discussed in Part -1 of this article.
