A testing system and application performs validation testing on a media services delivery system by generating test transactions and validating test results at a plurality of support systems updated by the test transactions in a test environment. Support systems are independent systems that may be geographically and network distant, thus are cumbersome to access for validating corresponding updates based on a test transaction. The test system is accessible via an Internet or network portal for accessing an application that generates a test transaction, invokes a system under test for implementing the test transaction, and validates the results of the support system updates with known values for successful test completion. The test system automates the identification, retrieval and comparison of test generated values with known values corresponding to a successful transaction, and is operable to perform a suite of tests in succession from a set of predetermined test transactions and corresponding known values.
