Code inspection: NUnit. Redundant expected result for void test method.

A unit test with the void return type and some ExpectedResult in the TestCase attribute may be a sign of one of the following problems:

• ExpectedResult is there by mistake, in which case you should remove it.

• The test was originally designed to return a result, in which case you need to rewrite the test method.

• Expected result and its value is written instead of a data value for the test method parameter (for example [TestCase(ExpectedResult = 100)]). In this case, you need to remove the ExpectedResult argument name and only leave the value [TestCase(100)]
