Run Spanner integration tests using Cloud Spanner Emulator

Install Cloud Spanner Emulator

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.

Run tests

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.

Running a binary locally

It can be useful to run the ResultDB service locally if you are testing new query functionality:

cd cmd/resultdb
luci-auth login -scopes "https://www.googleapis.com/auth/cloud-platform https://www.googleapis.com/auth/userinfo.email"
go run main.go \
 -cloud-project luci-resultdb-dev \
 -spanner-database projects/chops-spanner-testing/instances/testing/databases/luci-resultdb-staging \
 -auth-service-host chrome-infra-auth-dev.appspot.com \
