Integration Tests

In addition to the unit tests, you may run the integration test suite.

To run the integrations tests, creating and configuration of a project in the Google Developers Console is required.

After creating a project, you must create a service account. Ensure the project-level Owner IAM role (or Editor and Logs Configuration Writer roles) are added to the service account.

Once you create a project, set the following environment variables to be able to run the against the actual APIs.

  • GCLOUD_TESTS_GOLANG_PROJECT_ID: Developers Console project's ID (e.g. bamboo-shift-455)
  • GCLOUD_TESTS_GOLANG_KEY: The path to the JSON key file.

Install the gcloud command-line tool to your machine and use it to create the indexes used in the datastore integration tests with indexes found in datastore/testdata/index.yaml:

From the project's root directory:

# Set the default project in your env
$ gcloud config set project $GCLOUD_TESTS_GOLANG_PROJECT_ID

# Authenticate the gcloud tool with your account
$ gcloud auth login

# Create the indexes
$ gcloud preview datastore create-indexes datastore/testdata/index.yaml

The Sink integration tests in preview/logging require a Google Cloud storage bucket with the same name as your test project, and with the Stackdriver Logging service account as owner:

$ gsutil acl ch -g gs://$GCLOUD_TESTS_GOLANG_PROJECT_ID

Once you've set the environment variables, you can run the integration tests by running:

$ go test -v
