""" Smoke test script for Fuzzing
This script can be used to perform simple calls using `jsshell`
or whatever other tools you may add.
The call
is done via `taskcluster/kinds/fuzzing/kind.yml`
and
files contained
in the `target.jsshell.zip`
and `target.fuzztest.tests.tar.gz`
build artifacts are downloaded to run things.
Everything included
in this directory will be added
in
`target.fuzztest.tests.tar.gz` at build time, so you can add more scripts
and
tools
if you need. They will be located
in `$MOZ_FETCHES_DIR`
and follow the
same directory structure than the source tree.
