IsNull String. Gets a value that indicates whether the named column contains a null value. In this article. About getting a value from a datarow column, you use the Item property. See DataRow. Now if the stored procedure would return rows with NULL in ProductID , wouldn't that mean that you return amounts but you don't know the product :confused: What I'm after is that should you instead modify the SQL inside the stored procedure to possibly eliminate this kinds of rows or something else.

Of course I may be on a wrong track since you haven't described the logic and I'm just guessing based on the names :. Posted Oct pm Wendelius. Posted May pm Ankit Kandoliya. Maciej Los May am.

I suspect you are getting downvoted not only because the question was adequately answered over 4 years ago, but your solution is just a code dump without any explanation, nor do any of the variables match up to the original code in the question. Add your solution here. OK Paste as. I can't be the only one bumping into this.

In this case, I can't type int? So now I probably need to change the type of value in the test method signature to "object" and cast it to int? And then I still must use object null in the DataRow to avoid the "Error in executing test" message.

Sorry, something went wrong. So if you have something like:. Hope that gets rid of most of the inconvenience. This should be fixed in an up-coming update. This has been fixed in MSTest.

Strange that when I use the TestContext I get from the method marked with the Initialize attribute that it doesnt work.

Hopefully this will be of use to others who experience the same problem. AssemblyInitialize attribute identifies a method to be used before all tests in the assembly have run and to allocate resources obtained by the assembly.

ClassInitialize attribute identifies a method to be used before any of the tests in the test class have run and to allocate resources to be used by the test class. AssemblyInitializeAttribute Class. If so, as my understanding, when you use AssemblyInitialize attribute, the Initialize method will always run once when you run any of the tests.

So the TestContext can be initialized. But when you use ClassInitialize attribute, the Initialize method will run only in the specified test class. Yes, every test class in the project has a Initialize method, this is required to get access to the TestContext object.
