Keycloak Arquillian Integration Testsuite

Overview

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

How to run tests

See the file HOW-TO-RUN.md .

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.

More details...

Cluster Setup

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

The cluster setup is not supported for server on Undertow.

The setup includes:

a mod_cluster load balancer on Quarkus
two clustered nodes of Keycloak server on Quarkus

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

Quarkus

To run the tests against a Quarkus Server:

 mvn -Pauth-server-quarkus -Dauth.server.ssl.required=false clean verify

NOTE: At the moment the Quarkus server does not support SSL, thus it must be disabled.

To debug the server:

 mvn -Pauth-server-quarkus -Dauth.server.ssl.required=false -Dauth.server.debug=true clean verify

By default, debug port is 5005. To change it, set the auth.server.debug.port system property to another port.

NOTE: Not all tests are passing, this is a working in progress.

App Servers / Adapter Tests

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

Each adapter test class is annotated by one or more @AppServerContainer("app-server-*") annotations that links it to a particular Arquillian container. The AppServerTestEnricher then ensures the corresponding server is started during BeforeClass event and stopped during AfterClass event for that particular test class.

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

NOTE: Some corresponding adapter test modules are in tests/other/adapters submodules, and are activated by the same profiles. It will be transferred into base testsuite.

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 htmlunit which is used for fast "headless" testing. Other browsers can be selected with the -Dbrowser property, for example firefox. See HOW-TO-RUN.md and Arquillian Drone documentation for more details.

Utils classes

UI testing is sometimes very tricky due to different demands and behaviours of different browsers and their drivers. So there are some very useful Utils classes which are already dealing with some common stability issues while testing. See UIUtils, URLUtils and WaitUtils classes in the Base Testsuite.

Test Modules

Base Testsuite

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

Types of adapter tests

Using custom test servlets
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

~~Provided - In standalone.xml using secure-deployment. Wildfly only.~~ WIP
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.
