# Use the version from `mach vendor`, instead of a script that consults Git. This is wrong,
# because (1) it would use a Git checkout of _Gecko_ rather than CTS, and (2) we might not even
# have a Git checkout if we're using Mercurial.

# Apply patches from patch files.
#
# These must be applied prior to the `cargo run` step below, as it patches the original
# TypeScript sources. If we used `moz.yaml`'s `patches` mechanism, it would apply the patch to
# the TypeScript sources _after_ we have already processed them and written our tests to their
# final location.
# Patch the `baseResourcePath` used by the CTS so that the tests we
# generate are able to load resources correctly.
