I would like to write a callable function that accepts two objects, and compares 30+ properties of those objects with asserts. The issue is this needs to be done for about 20 existing unit tests and most future tests, and writing out the 30+ asserts each time is both time and space consuming.
I currently have a non unit test function that compares the objects, and returns a string with "pass" or a failure message, and use an assert to validate that in each unit test. However, its quite messy and I feel like I'm going against proper unit testing methods.
Is there a way to make a function that is callable from inside unit tests that uses asserts to check conditions?

There are five steps that you need to follow to create a parameterized test. Annotate test class with @RunWith(Parameterized. class). Create a public static method annotated with @Parameters that returns a Collection of Objects (as Array) as test data set.
All of the built-in attributes allow for data to be provided programmatically, but NUnit does not have any attributes that fetch the data from a file or other external source.
The first way to create data driven tests is by using the [TestCase] attribute that NUnit provides. You can add multiple [TestCase] attributes for a single test method, and specify the combinations of input and expected output parameters that the test method should take.
If you are using NUnit 2.5.5 or above, this is possible using the TestCase attribute.
Normal unit tests would be decorated with [Test], but we can replace that as follows:
[TestCase("0", 1)] [TestCase("1", 1)] [TestCase("2", 1)] public void UnitTestName(string input, int expected) { //Arrange //Act //Assert } That type of thing will be the way to do it - obviously take different params.
Look at this for help: http://nunit.org/?p=testCase&r=2.5
