#dumb test harness py

If something is stupid but it works, it's not stupid

Simple utility to run key presses, AT commands & wait for response form phone scriptable in python. Great for repetitive tasks as i.e. phone unlock, or UI tests with multiple key presses.

#running in console

run:

python3
from harness.common import conn

# for key press: 0 - 9, second parameter = wait time after key press, here set to '1'
conn.key(0, 1)
# ...
conn.key(9, 1)

# send AT command - '\r' is important - othervise modem will ignore command
conn.gsm("AT?\r") 

# wait for some data
data = conn.read(4)

#how:

Frame:

<STX>
{
    Type : harness::Enum::Events
    Data : [ <element for selected data type>, ]
}
<ETX>

• Frames start with Frame enum
• Fata is per enum
• All data between <STX> abd <ETX> is Json
• Binary data should be encoded (base64)
• Partial frames can be added easily

I considered protobuf, tlv and msgpack, protobuf ain't very easy when you want to have Any types inside, msgpack don't have schema. Json is super easy - json it is

#In app:

• bsp - UART3 added (can be USB, IP whatever really)
  • STX signals application that old data have to be ignored
  • ETX signals app to parse data
• EventManager
  • Informs on start of Eventmanager
  • Informs about application focus change
  • Reads emits fake key releases
• test/*.py - test code for handling phone
  • phone_start.py - wait till phone sends its on
  • phone_unlock.py - unlock phone and show desktop
  • switch_app.py - switch to sms app and back waiting for info on application focus change
  • walk presses on arrow keys for ~30 min
