We test code against two versions of Go, the minimum and maximum versions supported by our clients. To see which versions these are checkout our README.
In addition to the unit tests, you may run the integration test suite. These directions describe setting up your environment to run integration tests for all packages: note that many of these instructions may be redundant if you intend only to run integration tests on a single package.
To run the integrations tests, creation and configuration of two projects in the Google Developers Console is required: one specifically for Firestore integration tests, and another for all other integration tests. We'll refer to these projects as “general project” and “Firestore project”.
After creating each project, you must create a service account for each project. Ensure the project-level Owner IAM role role is added to each service account. During the creation of the service account, you should download the JSON credential file for use later.
Next, ensure the following APIs are enabled in the general project:
Next, create a Datastore database in the general project, and a Firestore database in the Firestore project.
Finally, in the general project, create an API key for the translate API:
GCLOUD_TESTS_API_KEYas described below.
Once the two projects are created and configured, set the following environment variables:
GCLOUD_TESTS_GOLANG_PROJECT_ID: Developers Console project's ID (e.g. bamboo-shift-455) for the general project.
GCLOUD_TESTS_GOLANG_KEY: The path to the JSON key file of the general project's service account.
GCLOUD_TESTS_GOLANG_FIRESTORE_PROJECT_ID: Developers Console project's ID (e.g. doorway-cliff-677) for the Firestore project.
GCLOUD_TESTS_GOLANG_FIRESTORE_KEY: The path to the JSON key file of the Firestore project's service account.
GCLOUD_TESTS_API_KEY: API key for using the Translate API created above.
As part of the setup that follows, the following variables will be configured:
GCLOUD_TESTS_GOLANG_KEYRING: The full name of the keyring for the tests, in the form “projects/P/locations/L/keyRings/R”. The creation of this is described below.
GCLOUD_TESTS_BIGTABLE_KEYRING: The full name of the keyring for the bigtable tests, in the form “projects/P/locations/L/keyRings/R”. The creation of this is described below. Expected to be single region.
GCLOUD_TESTS_GOLANG_ZONE: Compute Engine zone.
Install the gcloud command-line tool to your machine and use it to create some resources used in integration tests.
From the project's root directory:
# Sets the default project in your env. $ gcloud config set project $GCLOUD_TESTS_GOLANG_PROJECT_ID # Authenticates the gcloud tool with your account. $ gcloud auth login # Create the indexes used in the datastore integration tests. $ gcloud datastore indexes create datastore/testdata/index.yaml # Creates a Google Cloud storage bucket with the same name as your test project, # and with the Cloud Logging service account as owner, for the sink # integration tests in logging. $ gsutil mb gs://$GCLOUD_TESTS_GOLANG_PROJECT_ID $ gsutil acl ch -g firstname.lastname@example.org:O gs://$GCLOUD_TESTS_GOLANG_PROJECT_ID # Creates a PubSub topic for integration tests of storage notifications. $ gcloud beta pubsub topics create go-storage-notification-test # Next, go to the Pub/Sub dashboard in GCP console.

It may be useful to add exports to your shell initialization for future use. For instance, in
#### START GO SDK Test Variables # Developers Console project's ID (e.g. bamboo-shift-455) for the general project. export GCLOUD_TESTS_GOLANG_PROJECT_ID=your-project # The path to the JSON key file of the general project's service account. export GCLOUD_TESTS_GOLANG_KEY=~/directory/your-project-abcd1234.json # Developers Console project's ID (e.g. doorway-cliff-677) for the Firestore project. export GCLOUD_TESTS_GOLANG_FIRESTORE_PROJECT_ID=your-firestore-project # The path to the JSON key file of the Firestore project's service account. export GCLOUD_TESTS_GOLANG_FIRESTORE_KEY=~/directory/your-firestore-project-abcd1234.json # The full name of the keyring for the tests, in the form "projects/P/locations/L/keyRings/R". # The creation of this is described below. export MY_KEYRING=my-golang-sdk-test export MY_LOCATION=global export GCLOUD_TESTS_GOLANG_KEYRING=projects/$GCLOUD_TESTS_GOLANG_PROJECT_ID/locations/$MY_LOCATION/keyRings/$MY_KEYRING # API key for using the Translate API. export GCLOUD_TESTS_API_KEY=abcdefghijk123456789 # Compute Engine zone. (https://cloud.google.com/compute/docs/regions-zones) export GCLOUD_TESTS_GOLANG_ZONE=your-chosen-region #### END GO SDK Test Variables
Once you've done the necessary setup, you can run the integration tests by running:
$ go test -v ./...
Note that the above command will not run the tests in other modules. To run tests on other modules, first navigate to the appropriate subdirectory. For instance, to run only the tests for datastore:
$ cd datastore $ go test -v ./...
Some packages can record the RPCs during integration tests to a file for subsequent replay. To record, pass the
-record flag to
go test. The recording will be saved to the package
.replay file. To replay integration tests from a saved recording, the replay file must be present, the
-short flag must be passed to
go test, and the
GCLOUD_TESTS_GOLANG_ENABLE_REPLAY environment variable must have a non-empty value.
