Case study: the situation
 Large provider of triple play services over optic fiber
 Central order management system
 Test environment with many dependencies
 Around 10 systems for every order

6. Parasoft Proprietary and Confidential 6Parasoft Proprietary and Confidential 6
Case study: the past – challenges
 Order-specific data needs to be present in backend system
 Order configuration in backend requires manual intervention
 As a result:
 Limited test data
 Long test cycles
 Low test coverage
 No automated end-to-end testing
