# This script runs the sqlIntegrationTestSuite in a given server release

# against a specific Cloud SQL schema release. When invoked during presubmit

# tests, it detects code or schema changes that are incompatible with current

# deployments in production.

USAGE="

$(basename "$0") [--help]

or

$(basename "$0") OPTIONS

Run compatibility test between Nomulus server and Cloud SQL schema.

The --sut option specifies a system under test, which may be either nomulus

or sql. If sut is nomulus, the Nomulus server code in the local Git branch

must be able to work with deployed SQL schemas. This is verified by running

the sqlIntegrationTestSuite in the local branch with schemas already

deployed to sandbox and/or production.

If sut is sql, the schema in local branch must not break the currently

deployed servers. This is verified by running the sqlIntegrationTestSuite

in appropriate releases against the SQL schema in the local branch.

This script needs to fetch Github tags of deployed systems. On platforms

that performs shallow clone, such as Travis-ci, caller may need to invoke

'git fetch --tags'.

Options:

-h, --help show this help text

-p, --project

the GCP project with deployment infrastructure. It should

take the devProject property defined in the Gradle root

project.

-s, --sut the system under test, either sql or nomulus.

-e, --env the environment that should be tested, either sandbox or

production. If unspecified, both environments will be tested."
