Currently it's a bit difficult/cumbersome to pass parameters from a parent test to a subtest. The parent test has to be bound to a data source, or use a coded step to SetExtractedValue. When the customer only needs to pass simple static values/parameters (e.g. “Mary”, 4, “Error message”, etc.) things like a utility class are far too complicated (and require programming skills). It would be far easier to add a UI in which you can set/add a list of Key/Value pairs to be passed in as parameters. Under the cover it could use the SetExtractedValue API, but make a simple UI for setting those values.
