A comprehensive system for enabling automated configuration and testing of software applications and services is disclosed. The system includes test interfaces, a test database and test functionality. Configuration functionality allows for rapid, accurate and efficient set up of one or more test accounts. Data manipulation interfaces and methods allow for the inspection of state variables and manipulating state-based data to simulate, initiate and reverse transactional data. Application programming interfaces enable the testing of external systems with a target system that is simulated in the testing environment.
