Linux

The Cloud Spanner Emulator is part of the bundled gcloud, to make sure it's installed:

cd infra
gclient runhooks
eval `./go/env.py`
which gcloud # should show bundled gcloud
gcloud components list # should see cloud-spanner-emulator is installed

Mac

• Install Docker Desktop on Mac

If you are a Google employee, follow go/docker-for-mac first.

From command line, first set environment variables:

export INTEGRATION_TESTS=1
export SPANNER_EMULATOR=1

Then run go test as usual.

Note: If you run tests on Mac, please start Docker Desktop before running tests.
