13. Automation Life Cycle – Using Real Devices
• Today – Manual tests occurs at a point of change. New Device, New OS,
New Application, Network upgrades and changes → MCb Manual Test
• Automate Manual Test –
• Allowing tests to occur multiple times a day, finding problems quick and early
• In wireless the test path is always changing: Device, OS, Application, Network
Capacity, Platform, …
• Understand User Group TOL requirement
• MCb & User → Steps through Application with target device/OS
• Expected Results
• Validation Points
• Points of Interest
• Exceptions – Items not easily addressable by automation
• Logs / Video / Checkpoints for all or failed tests
• Implement TOL – Orchestrated through Automated Network Test, ANT
