[PATCH V2] perf test: Add support for testing gecko script

[Anup Sharma]

This commit add support for testing gecko script. The 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. Also it verifies the validity of the JSON format
using Python's JSON library if available.

To run this script:
./test_gecko.sh
or
bash test_gecko.sh

Expected output:

Hi Anup,

this works for me but when I run as root (using sudo) I need to set
PERF_EXEC_PATH. Running as a user it launches firefox profiler which I
don't think it should.

Thanks,
Ian

Hi Ian, thanks for testing this patch. I checked it seems like
gecko.py Line 359: webbrowser.open(f'{url}') is not launching
firefox or any browser when run as root. Few discussion have
already taken place which I am looking right now:
https://forums.opensuse.org/t/python-webbrowser-with-root/92189
https://github.com/pyinstaller/pyinstaller/issues/6334
I will check if there is any way to launch browser as both root
and user.

Thanks,
Anup
