CF Smoke Tests

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. They are also safe to run periodically against a production environment as they place minimal load on a system and can be configured to require access only by a regular user. In particular, Cloud Foundry operators can use these tests as a monitoring tool against their running deployment.

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.

Running the tests

Set up your go environment

Set up your golang development environment, per golang.org.

You will probably also need the following SCM programs in order to go get source code:

• git
• mercurial
• bazaar

See Go CLI for instructions on installing the go version of cf.

Make sure that curl is installed on your system.

Make sure that the go version of cf is accessible in your $PATH.

Check out a copy of cf-smoke-tests and make sure that it is added to your $GOPATH. The recommended way to do this is to run go get -d github.com/cloudfoundry-incubator/cf-smoke-tests. You will receive a warning "no buildable Go source files"; this can be ignored as there is no compilable go code in the package.

All go dependencies required by the smoke tests are vendored in cf-smoke-tests/Godeps. The test script itself, bin/test, ensures that the vendored dependencies are available when executing the tests by prepending this directory to $GOPATH.

Test Setup

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 application domain

Below is an example integration_config.json:

{
  "suite_name"         : "CF_SMOKE_TESTS",
  "api"                : "api.10.244.0.34.xip.io",
  "apps_domain"        : "10.244.0.34.xip.io",
  "user"               : "admin",
  "password"           : "admin",
  "org"                : "CF-SMOKE-ORG",
  "space"              : "CF-SMOKE-SPACE",
  "use_existing_org"   : false,
  "use_existing_space" : false,
  "logging_app"        : "",
  "runtime_app"        : ""
}

If you are running the tests with version newer than 6.0.2-0bba99f of the Go CLI against bosh-lite or any other environment using self-signed certificates, add

  "skip_ssl_validation": true

to your integration_config.json as well.

Test Execution

To execute the tests, run:

./bin/test

Internally the bin/test script runs tests using ginkgo.

Arguments, such as -focus=, -nodes=, etc., that are passed to the script are sent to ginkgo

For example, to execute tests in parallel across two processes one would run:

./bin/test -nodes=2

Seeing command-line output

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

./bin/test -v

Capturing CF CLI output

Set 'artifacts_directory' in your integration_config.json (as shown below) to store cf cli trace output. The output files will be saved inside the given directory.

  "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
...

Changing Smoke Tests

Dependency Management

Smoke Tests use godep to manage go dependencies.

All go packages required to run smoke tests are vendored into the cf-smoke-tests/Godeps directory.

When making changes to the test suite that bring in additional go packages, you should use the workflow described in the Add or Update a Dependency section of the godep documentation.
