zhangshoukui 369729eea4 testing/drivers/drivertest: Uniform test case name 
1.Some test functions are named too simply
2.Many driver tests depend on specific configurations and hardware, and the unified specification name facilitates cmocka to skip tests by using the skip parameter for wildcard matching
