#!/bin/bash
git stash apply || exit 125
# build the test
#   for a chromium/blink unittest, this is:
#   ( echo n | gclient sync ) || exit 125
#   autoninja -C out/Debug blink_unittests || exit 125

# run the test
#  for a chromium/blink, this is:
#  out/Debug/blink_unittests --gtest_filter=...

exit $rv

To use, add your new test and then stash it with "git stash".

Then, use git bisect:
git bisect start
git bisect good <revision>
git bisect bad <revision>
git bisect run bisect-stash-build-run.sh
