A pending change to the flutter_drone LUCI recipe is using a logging library that sets the FLUTTER_TEST_OUTPUTS_DIR environment variable (see https://flutter.googlesource.com/recipes/+/b111cd3ef2297e66905cc48c2cfedce0cf1ba46f) flutter_driver uses FLUTTER_TEST_OUTPUTS_DIR as its output directory if it is set. run_web_tests invokes flutter_driver and needs to look for outputs in that directory.
