Keycloak Arquillian Integration Testsuite

Overview

For overview see the Modules Overview section at the bottom of this README.

Container Lifecycles

Auth Server

Keycloak server is automatically started by the testsuite on the BeforeSuite event and stopped on AfterSuite event.

By default the server runs in embedded Undertow.

Wildfly/EAP

Testsuite supports running server on Wildfly/EAP. For this it's necessary to:

• build the project including the distribution module (artifact keycloak-server-dist/-overlay needs to be available before running the testsuite),
• activate profile auth-server-wildfly or auth-server-eap7.

More details...

Cluster Setup

The cluster setup for server can be enabled by activating profile auth-server-cluster.

The cluster setup is not supported for server on Undetow. Profile auth-server-wildfly or auth-server-eap needs to be activated.

The setup includes:

• a mod_cluster load balancer on Wildfly
• two clustered nodes of Keycloak server on Wildfly/EAP

Clustering tests require MULTICAST to be enabled on machine's loopback network interface. This can be done by running the following commands under root privileges:

route add -net 224.0.0.0 netmask 240.0.0.0 dev lo
ifconfig lo multicast

App Servers / Adapter Tests

Lifecycle of application server is always tied to a particular TestClass.

Each adapter test class is annotated by @AppServerContainer("app-server-*") annotation that links it to a particular Arquillian container in arquillian.xml. The AppServerTestEnricher then ensures the server is started during BeforeClass event and stopped during AfterClass event for that particular test class. In case the @AppServerContainer annotation has no value it's assumed that the application container is the same as the auth server container - a "relative" adapter test scenario.

The app-servers with installed Keycloak adapter are prepared in servers/app-server submodules, activated by -Papp-server-MODULE. More details.

The corresponding adapter test modules are in tests/other/adapters submodules, and are activated by the same profiles.

SuiteContext and TestContext

These objects are injected into AbstractKeycloakTest class so they can be used everywhere. They can be used to get information about the tested containers, and to store information that won't survive across test classes or test methods. (Arquillian creates a new instance of test class for each test method run, so all data in the fields is always lost.)

REST Testing

The AbstractKeycloakTest has an initialized instance of AdminClient. Subclasses can use it to access any REST subresources.

UI Testing

Page Objects

Page Objects are used by tests to access and operate on UI. They can be injected using annotation @Page provided by the Arquillian Graphene extension.

The base class for all page objects used throughout this Arquillian testsuite is AbstractPage, and it's subclass AbstractPageWithInjectedUrl.

For the page objects for the adapter test apps the URLs are injected automatically by Arquillian depending on actual URL of the deployed app/example.

For the pages under the /auth context the URL is only injected to the AuthServerContextRoot page object, and the URL hierarchy is modeled by the class inheritance hierarchy (subclasses/extending of AuthServerContextRoot).

Browsers

The default browser for UI testing is phantomjs which is used for fast "headless" testing. Other browsers can be selected with the -Dbrowser property, for example firefox. See Arquillian Graphene documentation for more details.

Test Modules

Base Testsuite

The base testsuite contains custom Arquillian extensions and most functional tests. The other test modules depend on this module.

Admin Console UI Tests

Tests for Keycloak Admin Console are located in a separate module tests/other/console and are disabled by default. Can be enabled by -Pconsole-ui-tests.

Adapter Tests

Adapter tests are located in submodules of the tests/other/adapters module.

They are disabled by default; they can be enabled by corresponding profiles. Multiple profiles can be enabled for a single test execution.

Types of adapter tests

1. Using custom test servlets
2. Using example demo apps from keycloak/examples modules.

Relative vs Non-relative scenario

The test suite can handle both types. It automatically modifies imported test realms and deployments' adapter configs based on scenario type.

Scenario	Description	Realm config (server side)	Adapter config (client side)
Relative	auth server == app server	client baseUrl, adminUrl and redirect-uris can be relative	auth-server-url can be relative
Non-relative	auth server != app server	client baseUrl, adminUrl and redirect-uris need to include FQDN of the app server	auth-server-url needs to include FQDN of the auth server

Adapter Config Mode

1. Provided - In standalone.xml using secure-deployment. Wildfly only. WIP
2. Bundled - In the deployed war in /WEB-INF/keycloak.json. Default.

Custom Arquillian Extensions

Custom extensions are registered in META-INF/services/org.jboss.arquillian.core.spi.LoadableExtension.

MultipleContainersExtension

• Replaces Arquillian's default container handling.
• Allows to manage multiple container instances of different types within a single test run.
• Allows to skip loading disabled containers based on enabled config property in arquillian.xml.

KeycloakArquillianExtension

• AuthServerTestEnricher - Handles lifecycle of auth server and migrated auth server.
• AppServerTestEnricher - Handles lifecycles of app servers.
• CustomUndertowContainer - Custom container controller for JAX-RS-enabled Undertow with Keycloak Server.
• DeploymentArchiveProcessor - Modifies adapter configs before test apps are deployed.
• DeploymentTargetModifier - Ensures all test app deployments are targeted at app server containers.
• URLProvider - Fixes URLs injected by Arquillian Graphene which contain value 127.0.0.1 instead of required localhost.
