The simplest testiny to get started with Arquillian is aqruillian incorporate it into the test suite of a project build that offers dependency management. Today, the most widely used build tool in this category is Apache Maven. This guide will navigate you to your first green bar using a new Maven project.
Arquillian does not depend on Maven, or any specific build tool for that matter. It works just as well—if not better—when used in a project with an Ant or Gradle build.
Ideally, the build tool should offer dependency management as it simplifies the task of including the Arquillian libraries since they are distributed in the Maven Central repository. This guide assumes you have Maven available, either in your command shell or your IDE.
Select from one of the two options above to jump to the instructions. If you already have a Maven project, you can use this section as review to ensure you have the proper dependencies before moving on. Respond to the prompts by entering the value shown afquillian each double colon in the afquillian below.
This command generated a Maven-based Java project inside the current directory in a new folder named arquillian-tutorial.
Switch to that directory. Testin file structure of the project is shown below. The project generator also created a Java package named org. You should put your Java source files in this package rather than at the root of the java folder.
Go ahead and open up the pom. You should see an XML file containing basic project information, a build section and a dependencies section. Arquillian also supports TestNG 5.
After making this change, the file should match the contents below slightly formatted:. Open up the pom. The foundation of your project is now ready! Skip to the next section, Open the Project in Eclipseso we can start writing some code! JBoss Forge is a command shell for rapid-application development in a standards-based environment. Installing Forge is a relatively short process, and this guide will take you through the fundamentals. Follow these simple steps to get Forge installed:.
We recommended setting User variables for Forge, unless you have placed the unzipped distribution in a folder where all users can access it. Now that Forge tesitng installed i.
Inside the Forge shell, execute the following command to create a blank project, much like we created a project using the Maven Archetype above:.
Arquillian – So you can rule your code. Not the bugs.
This command generates a Maven-based Java project inside a new folder named arquillian-tutorial under the current directory. Forge adds the JBoss Community repository to the pom.
This repository is not required to use Arquillian. However, you can keep it if you are using other libraries only available in the JBoss Community repository. If you do tesing to remove the repository, you can easily do so using the following Forge command:. You can run Arquillian tests from the IDE without any testimg configuration. Begin by launching Eclipse.
Since this is a Maven project, you need the Maven Integration for Eclipse m2e plugin installed in order to open the project. Follow these steps to install it from the Eclipse Marketplace sort gudie like the app store for Eclipse. However, if you just want the Maven integration without the extras that JBoss Tools brings, you can follow these steps instead:.
Eclipse will recognize the Maven project and open it in the Project Navigator view. If you expand the project, it should look similar to this image:.
In order to write an Arquillian test, we need arquilliab have a component for it to test. Replace the contents of the file arquillizn this greeter logic:. We want to verify that this class behaves properly when invoked as a CDI bean.
Of course, we could simply write a unit test.
That calls for an Arquillian test! Once again open up the pom. We need to instruct Maven which versions of the artifacts to use. You need all of these libraries to write and compile a JUnit Arquillian test. An Arquillian test looks just like a unit test, just with some extra flair.
Arquillian then looks for a public static method annotated with the Deployment arqujllian to retrieve the test archive i. Then some magic happens and each Test method is run inside the container environment. The Deployment method is only mandatory for tests that run inside the container and no extension is loaded that otherwise generates the test archive.
Client-side tests do not require a test archive, and therefore, do not require a Deployment method. The purpose of the test archive is to isolate the classes and resources which are needed by the test from the remainder of the classpath. Unlike a normal unit test, Arquillian does not simply tap the entire gkide.
The micro-deployment strategy lets you focus on precisely the classes you want to test.
As a result, the test remains very lean and manageable. Once the ShrinkWrap archive is deployed to the server, it becomes a real archive. The container deployer has no knowledge that the archive was package by ShrinkWrap.
You can think of ShrinkWrap as a Java-based build tool, with one exception. In the optimal case, it streams the archive to the server instead of writing the archive to disk. But what it creates is an authentic archive. ShrinkWrap also supports resolving artifacts libraries and create configuration files programmatically, which can then be added to the test archive.
For a more thorough introduction to ShrinkWrap, see the ShrinkWrap introduction guide. It includes the Greeter class that the test will invoke and an empty beans.

If you want to see the contents of the archive that ShrinkWrap creates when the test is run, you can print the archive to stdout i. Now all we need to do is inject the Greeter instance into a field directly above the test method and replace arqukllian unimplemented test method with one that asserts the behavior of the bean.
Replace the test method with the code below and add an import for javax. However, we first need to add a container adapter to the classpath.
Arquillian selects the target container based on which container adapter is available on the test classpath. A container adapter controls and communicates with a container e.
Once you add all the necessary Arquillian libraries to the classpath, you can run an Arquillian test just like a unit test, whether you are running it from the IDE, the build script or any other test plugin.
You should then see the JUnit view appear, revealing a green bar! How do you know that CDI really worked? For all you know, Arquillian created a new instance of the Greeter class and injected it into the test without any involvement from CDI. Next, open up the Greeter class and arquilliqn a new constructor that will inject PhraseBuilder using constructor injection.
Then, delegate the task of creating the greeting to the injected bean. Now, in order for the test to work, an instance of PhraseBuilder must be created, its PostConstruct method must be invoked and it must be injected into the constructor of Greeter when an instance of Greeter is created. We can be certain CDI is working if guiee that comes together. Because we created a new class, we must be sure that it gets included in the test archive that the Deployment method returns.
Simply change this line:. Run the test again. You should get another green bar! This is going to be a short chapter. Because an Arquillian test is so straightforward that you debug it exactly how you debug a unit test.

Just add a breakpoint anywhere—either in the test or in the application code. Have fun poking around! Instead, you need to start the container in debug mode and attach the debugger. It takes care of loading the CDI environment and injecting beans directly into the test.
Best of all, when using an embedded CDI container, the test runs just as quickly as a unit test. Is the embedded container telling the whole story? Will the component work if running inside a full container? If you intend to use a real container, read on. As you learned earlier, Arquillian selects the container based on which container adapter is on the classpath.
To switch to another container, you just change which container adapter is on the classpath before you run the test. You can only have one container adapter on the classpath at a time. Arquillian will abort execution of the test if it detects multiple adapters. One way to swap the libraries on the classpath is to manually edit the dependencies defined in pom. The recommended approach is to use Maven profiles.
