The other tests are like UI Test, Browsing tests throughput tests are done to ensure the practical throughput rate supported my UE/MS. • The test cycle/ regression cycle covers different scenarios like MO/MT CS/PS call, DL/UL throughput measurement, IRAT / Cell reselection, call stability, idle mode stability etc. • Sometimes AT-Commands are used to operate the UE manually in command mode. Responsibilities: • Requirement analysis, test case study. • Write test plan and work assignment to engineers and trouble shooting. • Regression test case execution and issue reproduction if requested. • Trouble shooting during test case execution. • Comparison performance result with standard and reference UE. • Providing the debug inputs to Developer team about the failure scenarios. • Closely working with development team to narrow down the issues. • Bug documentation and bug tracking and retest for failures.
