A graphical user interface allows a user with little or no knowledge of XML to compose and manage automated tests for a target testing platform and testing framework. An example system opens an XML file storing test parameters and converts the test parameters to fields in a graphical user interface for presentation to a user. The system receives, from the user, input via the graphical user interface to modify the test parameters to yield modified test parameters, and outputs the modified test parameters, in XML format, for use with a testing framework which is configured to perform automated tests on a target test platform based on the modified test parameters.
