Question

I have test methods decorated with a DataSource attribute like:

[DataSource(PROVIDER_INVARIANT_NAME, CONNECTION_STRING, 
"Test Case#", DataAccessMethod.Sequential), 
TestMethod]

with the test case number in MTM replacing “Test Case#”. I’m trying to get that number within the unit test but TestContext.DataRow.Table.TableName is always “Table1”. Can anyone tell me how to get the real value?

Answer 1

Unless I’m wrong, the “TestCase#” cannot be replaced by MTM, so propably you have manually added it in all your DataSource attributes.

This value is constant. Why don’t you add a constant variable to your TestClass and then use it on both the DataSourceAttribute and your TestMethod?

EDIT
You can also access the DataSourceAttribute directly:

[TestClass]
public class TestClass
{
    public DataSourceAttribute DataSource
    {
        get
        {
            return (DataSourceAttribute)Attribute.GetCustomAttribute(typeof(TestClass).
                GetMethod("TestMethod"), typeof(DataSourceAttribute));
        }
    }

    [DataSource(PROVIDER_INVARIANT_NAME, CONNECTION_STRING, 
        "Test Case#", DataAccessMethod.Sequential), TestMethod]
    public void TestMethod()
    {
        string TestCaseId = DataSource.TableName;
    }
}
