There is one drawback, as compared to InlineData and MemberData types, when we run tests inside of Visual Studio. For example, when we test a controllers action to see if its returning the correct view. We can define multiple data decorators for each test, and are not limited to only using a single type. For example, the following is a perfectly valid declaration: [Theory] [InlineData(1,2,3,6)] [InlineData(1,1,1,3)] [MemberData(nameof(MyDataPropName))] public void TestSum(int a, int b, int c, int sumTotalResult). Facts and theories While facts are used to test invariant conditions, theories are tests that are true for a particular set of data passed as argument to the method.
