Tests

This folder contains automated tests for this Module. All of the tests are written in Go. Most of these are "integration tests" that deploy real infrastructure using Terraform and verify that infrastructure works as expected using a helper library called Terratest.

WARNING WARNING WARNING

Note #1: Many of these tests create real resources in a GCP project and then try to clean those resources up at the end of a test run. That means these tests may cost you money to run! When adding tests, please be considerate of the resources you create and take extra care to clean everything up when you're done!

Note #2: Never forcefully shut the tests down (e.g. by hitting CTRL + C) or the cleanup tasks won't run!

Note #3: We set -timeout 60m on all tests not because they necessarily take that long, but because Go has a default test timeout of 10 minutes, after which it forcefully kills the tests with a SIGQUIT, preventing the cleanup tasks from running. Therefore, we set an overlying long timeout to make sure all tests have enough time to finish and clean up.

Running the tests

Prerequisites

• Install the latest version of Go.
• Install dep for Go dependency management.

dep ensure

Run all the tests

cd test
go test -v -timeout 60m

Run a specific test

To run a specific test called TestFoo:
