BMS Testing challenges
➢ Multiple subprojects fast iterative test and delivery
➢ Multiple subprojects lifecycle management, especially requirements and test case
2019/5/3CATL Confidential Page 6
Virtual testing environment
Testing architecture based on CANoe+vTESTstuidio
➢ Easy switch between both setups for SW test and System test
➢ Reuse the test case suit across the phases

HW Emulator
Abstract test interface variable and HW emulation
➢Share the same test interface variable between SW test and system test
➢Emulate the HW function and peripheral electrical architecture

Multiple project variants management
CANoe and vTESTstuidio support management of multiple project
➢ CANoe and vTESTstudio share the same configuration parameters from variation
➢ vTESTstudio supports variation choice by variant dependencies

Multiple project variants management
vTESTstudio and ALM support the project management
➢ Test Script directly generates test cases and then be submitted to ALM to trace related
requirements
➢ Automatically submitted to ALM and generated test section by test result

vTESTstudio and ALM support the
project management
➢ Subproject test case can be
branched from platform test library
by variant parameter
➢ Support same configuration of test
environment, requirement and test
case
