Run Tast tests with servo
How to run tast test with servo
Problem
I want to run a tast test with servo. Here is an example tast test with Servo.
Solution
Step 1: Lease a servo device.
When leasing a DUT with crosfleet, a servo device will also be leased.
crosfleet dut lease -board octopus
Step 2: SSH to leased DUT and Servo
The above command will get back the location of the leased DUT and servo. With
that, we can ssh into the DUT and the servo. For example, if the DUT is on
chromeos6-row6-rack12-host14 and the servo is on
chromeos6-row15-rack8-labstation3, we can do below command to ssh into them.
ssh -L 7778:localhost:22 chromeos6-row6-rack12-host14
ssh -L 7779:localhost:22 chromeos6-row15-rack8-labstation3
Step 3: Start the servo
start servod PORT=9990
Step 4: Run the test
tast -verbose run -var=servo=localhost:9999:ssh:7779 localhost:7778 feedback.LaunchFeedbackFromPowerButton
