"""Incremental dEQP
This script will run a subset of dEQP test on device to get dEQP dependency.
Usage 1: Compare with a base build to check if any dEQP dependency has
changed. Output a decision if dEQP could be skipped, and a cts-tradefed
command to be used based on the decision.
python3 incremental_deqp.py -s [device serial] -t [test directory] -b
[base build target file] -c [current build target file]
Usage 2: Generate a file containing a list of dEQP dependencies for the
build on device.
python3 incremental_deqp.py -s [device serial] -t [test directory]
