The test env could change when we running test from different computers.
|
|
Test env config provide ``get_variable`` method to allow user get test environment related variables.
|
|
It will first try to get variable from config file.
|
|
If failed, then it will try to auto detect (Not supported yet).
|
|
|
|
Config file format is yaml. it's a set of key-value pair. The following is an example of config file::
|
|
|
|
Example_WIFI:
|
|
ap_ssid: "myssid"
|
|
ap_password: "mypassword"
|
|
Example_ShieldBox:
|
|
attenuator_port: "/dev/ttyUSB2"
|
|
ap_ssid: "myssid"
|
|
ap_password: "mypassword"
|
|
|
|
It will first define the env tag for each environment, then add its key-value pairs.
|
|
This will prevent test cases from getting configs from other env when there're configs for multiple env in one file.
