Purpose

Smoke tests are a suite of basic core functionality tests for Cloud Foundry. They are suitable as an initial test against a new or updated deployment to reveal fundamental problems with the system.

There are three tests in this suite, all of which are pretty simple:

runtime: Pushes an app and validates that HTTP requests are properly routed to the app.
logging: Pushes an app and validates that logs can be fetched for the app.
isolation_segments: Entitles an org to an isolation segment and pushes two apps, one to the isolation segment, and one to the shared segment. The test validates that isolated apps are only accessed via the isolated router, and that apps on the shared segment are only accessed via the shared router.

They are not intended to test more sophisticated functionality of Cloud Foundry or to test administrator operations. The CF Acceptance Tests do perform this more extensive testing, although they are designed to be run as part of a development pipeline and not against production environments.

Test Setup

Dependencies

Make sure you have the following installed:

Check out a copy of cf-smoke-tests. The recommended way to do this is to clone the repo, if you don't have it: git clone [email protected]:cloudfoundry/cf-smoke-tests.git. Alternatively, you can simply cd into a pre-existing cf-smoke-tests directory and run git pull.

To run the CF Smoke tests, you will need:

a running CF instance
an environment variable $CONFIG which points to a .json file that contains the relevant configuration information.

Config

Below is an example integration_config.json:

{
  "suite_name"                      : "CF_SMOKE_TESTS",
  "api"                             : "api.bosh-lite.com",
  "apps_domain"                     : "bosh-lite.com",
  "user"                            : "non-admin",
  "password"                        : "super-secure",
  "cleanup"                         : true,
  "logging_app"                     : "",
  "runtime_app"                     : "",
  "enable_windows_tests"            : false,
  "windows_stack"                   : "windows",
  "isolation_segment_name"          : "is1",
  "isolation_segment_domain"        : "is1.bosh-lite.com",
  "enable_isolation_segment_tests"  : true,
  "linux_buildpack_name"            : "binary_buildpack",
  "windows_buildpack_name"          : "hwc_buildpack"
}

The following are special case configurations.

Credentials

Must supply one of the following login credentials.

User credentials

  "user":     "username",
  "password": "password"

Client credentials

  "client":        "client-name",
  "client_secret": "client-secret"

Skip SSL validation

If you are running the tests against bosh-lite or any other environment using self-signed certificates, add:

  "skip_ssl_validation": true

Org and space cleanup

If you would like to preserve the organization, space, and app created during the tests for debugging, add:

  "cleanup": false

Windows

If you have deployed Windows cells, add:

  "enable_windows_tests": true,
  "windows_stack":        "windows"

The valid options for windows_stack are windows2016 and windows.

Isolation segments

If you'd like to run isolation segment tests, add:

  "enable_isolation_segment_tests": true,
  "isolation_segment_name": "name",
  "isolation_segment_domain": "domain"

For more details on how to setup routing for isolation segments, read this document.

Artifacts directory

To store cf cli trace output, set

  "artifacts_directory": "/tmp/smoke-artifacts"

The following files may be created:

CF-TRACE-Smoke-1.txt
CF-TRACE-Smoke-2.txt
junit-Applications-1.xml
...

Admin vs. Regular User

Smoke tests can be configured with two types of users.

Regular user: Smoke tests can be configured to run with a non-admin user. If you'd like to use a non-admin user, it must be able to assign user roles (either OrgManager or SpaceManager roles). Please refer to the Roles and Permissions for Active Orgs documentation for more information. In this configuration, organization and space must be created ahead of time and provided as org and space configuration properties, respectively. Also, use_existing_org and use_existing_space must be set to true. This configuration is recommended for tests run against environments run by humans, in particular, production deployments.
Admin user: Smoke tests can be configured to run using admin credentials. Given this configuration, the tests may or may not use existing resources like orgs and spaces, because an admin user can easily create them. This configuration is recommended for tests run against environments created using automation tools, for example, CI (continuous integration) environments on development teams.

NOTE: If you are enabling isolation segments tests and would like to use a non-admin user, the existing organization provided as org configuration property must be entitled to the isolation segment provided by isolation_segment_name. In addition, you need to create a space inside org and provide it as isolation_segment_space. isolation_segment_space must be assigned the isolation segment isolation_segment_name.

NOTE: If the default identity provider for your deployment is not UAA, it is recommended that you set the origin configuration property to UAA, and ensure the user credentials that you provide are registered with UAA.

Running Tests

To execute the tests, run:

./bin/test

Internally the bin/test script runs tests using ginkgo.

Arguments, such as --keep-going, --flake-attempts [int], etc., that are passed to the test script are passed through to ginkgo. For example, to execute tests in parallel one would run:

./bin/test -p

Seeing command-line output

To see verbose output from cf, use ginkgo's -v flag:

./bin/test -v

Guidelines

The goal of smoke tests is to provide a small, simple set of tests to verify basic deployment configuration. As such, we have some guidelines for contributing new tests to this suite.

Creating API resources in the test

One basic rule for good test design is not to mock the object under test. We can translate that idea to a suite like smoke tests in the following way: If smoke tests exist to validate deployment configuration, then smoke tests should not itself mutate deployment configuration.

There are, however, several resources that can be defined as either deployment configuration or as API resources. For example, shared app domains and isolation segments are both resources that can be created via the API, so it might be tempting to have a test create them in a BeforeSuite. However, shared app domains and isolation segments really represent deployment configurations. Accordingly, smoke tests should not create those resources as part of the test; instead, it should validate (either implicitly or explicitly) that those resources have already been created, and configured correctly.

Other API resources, like orgs and spaces that exist simply to be able to push an app, can absolutely be created as part of a test.

Admin vs. Regular User workflows

Please refer to the Regular vs admin user section to understand the difference between these two workflows.

Dependency Management

cf-smoke-tests use modules to manage go dependencies. These dependencies, together with the version of go itself, are automatically bumped by the CI pipeline defined in the cf-smoke-tests-release repo.

All go packages required to run smoke tests are vendored into the vendor/ directory.

	var useExistingApp = testConfig.LoggingApp != ""
	var appName string

	Describe("cf logs", func() {
	AfterEach(func() {
	defer func() {
	if testConfig.Cleanup && !useExistingApp {
	Expect(cf.Cf("delete", appName, "-f", "-r").Wait(testConfig.GetDefaultTimeout())).To(Exit(0))
	}
	}()
	smoke.AppReport(appName, testConfig.GetDefaultTimeout())
	})

	Context("linux", func() {
	BeforeEach(func() {
	if !useExistingApp {
	appName = generator.PrefixedRandomName("SMOKES", "APP")
	Expect(cf.Cf("push", appName, "-b", "ruby_buildpack", "-p", smoke.SimpleRubyAppBitsPath, "-d", testConfig.AppsDomain).Wait(testConfig.GetPushTimeout())).To(Exit(0))
	}
	})

	func SendRequestWithSpoofedHeader(host, domain string) *http.Response {
	req, _ := http.NewRequest("GET", fmt.Sprintf("http://wildcard-path.%s", domain), nil)
	req.Host = host

	resp, err := http.DefaultClient.Do(req)
	Expect(err).NotTo(HaveOccurred())
	return resp
	}
