The data source cannot be changed based on input during a test because all the data is loaded and cached before the first test runs. To change data sources at run-time, you can implement your own data binding. Use ADO.NET or a StreamReader when you read from a file.

This attribute can be applied to classes. This attribute can be applied multiple times. For more information about how to use attributes, see Extending Metadata Using Attributes.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
