# This script is used as a single command to run the x-pack tests.
#
# It will attempt to check out 'elasticsearch' into a sibling directory
# unless the environment variable `USE_EXISTING_ES` has a value. The
# branch of elasticsearch which will be checked out depends on
# environment variables. If running locally, set GIT_BRANCH. When
# running in Jenkins, that env var is set. When running a PR
# jenkins job, the variables PR_SOURCE_BRANCH and PR_TARGET_BRANCH
# will be set and the source branch will be looked for in elasticsearch
# before falling back to the target branch name.
#
# It will also attempt to install the appropriate version of node.js
# for the Kibana plugin tests using nvm, unless
# `xpack.kibana.build=false` is defined in
# ~/.gradle/gradle.properties. Set a custom nvm directory using the
# `NVM_DIR` environment variable.
#

# Turn on semi-strict mode
set -e
set -o pipefail

# Allow the user choose different test through a single cli arg
# default to `check` if no argument has been supplied
