A parameterized test is a test with a set of parameters and the test will be

run against each parameter. This allows to test logic with different
|
||
|
|
parameters without without writing multiple copies of the same test.

|
|
An example use case of parameterized test is service name aware HAL testing
|
||
|
|
which we expect to run the same test logic against all service instances
|
||
|
|
through their corresponding service names. e.g to test graphics.composer HAL

|
against two different instance: default and vr.
