Question

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?

To answer the final part, you can of course have Asserts inside another function. Asserts work by raising exceptions which the test runner catches, and interprets as a failure, so have a Test like so will work fine:

public void CheckAsserts(string value)
{
    Assert.IsNotNull(value);
}

[TestCase("yes!")]
public void MyTest(string value)
{
    CheckAsserts(value);
}
