Subject: [PATCH v5 8/8] perf test: Add support for testing perf gecko script
This commit add support for testing perf-gecko script.
This test checks for the presence of required sections such as "meta,"
"threads," "samples," "frameTable," "stackTable," "stringTable,"
and "pausedRanges" which are few essential parameter to be present
in output file. It also tests for user-defined color changes using
the --user-color flag, and verifies the validity of the JSON format
using Python's JSON library if available.
