I am having a problem using Visual Studio data driven testing. I have tried to deconstruct this to the simplest example.
I am using Visual Studio 2012. I create a new unit test project.
I am referencing system data.
My code looks like this:
namespace UnitTestProject1
{
[TestClass]
public class UnitTest1
{
[DeploymentItem(@"OrderService.csv")]
[DataSource("Microsoft.VisualStudio.TestTools.DataSource.CSV", "OrderService.csv", "OrderService#csv", DataAccessMethod.Sequential)]
[TestMethod]
public void TestMethod1()
{
try
{
Debug.WriteLine(TestContext.DataRow["ID"]);
}
catch (Exception ex)
{
Assert.Fail();
}
}
public TestContext TestContext { get; set; }
}
}
I have a very small csv file that I have set the Build Options to to 'Content' and 'Copy Always'. I have added a .testsettings file to the solution, and set enable deployment, and added the csv file.
I have tried this with and without |DataDirectory|, and with/without a full path specified (the same path that I get with Environment.CurrentDirectory). I've tried variations of "../" and "../../" just in case. Right now the csv is at the project root level, same as the .cs test code file.
I have tried variations with xml as well as csv.
TestContext is not null, but DataRow always is.
I have not gotten this to work despite a lot of fiddling with it. I'm not sure what I'm doing wrong.
Does mstest create a log anywhere that would tell me if it is failing to find the csv file, or what specific error might be causing DataRow to fail to populate?
I have tried the following csv files:
ID
1
2
3
4
and
ID, Whatever
1,0
2,1
3,2
4,3
So far, no dice.
