# Runs unit tests using karma.
# You can run it simply using `gulp test:unit`.
# You can also pass some karma arguments like this: `gulp test:unit --browsers Chrome`.
#
# NOTE if you want to run simultaneously `gulp` and `gulp test:unit` in 2 terminals,
#   you can have some bugs with karma turning off its' watchers when `gulp` cleans the build directory.
#   To solve this, instead run `gulp test:unit --TMP_BUILD_DIR=1`,
#   so karma will be building its' files into a different, temporary directory.
