Parameters for a parametrized test can be supplied by a class method or property. This tutorial shows how to use the MemberData attribute to designate the class member that contains the test data. See how to use the C# yield keyword in the method to return the data successfully.
- [Voiceover] In this theory I have…a single piece of inline data.…As you recall that means that when…this test is run it'll be run one…time with the single piece of data.…If I want to run multiple tests with…multiple parameters then I create…multiple inline datas.…If I have three inline datas my test…gets run three times.…There could be times when the number…that I'm generating or the piece of data…that I'm generating for the inline data is complex,…in that case it would be beneficial if I could…write some code to generate the information.…
Another case where that would be beneficial…is if I have lots of inline test cases.…Imagine for a second that I have 300…pieces of test data I have to use for this theory.…Writing 300 attributes on this method…would be tedious, instead it would be nice…if I could put that in code.…Action the support sys with something called a…member data, that means I can create…a property or a method in my class…until the theory the to call that.…Typically you put the member data in the…same class but that's not a strict requirement.…
