Marrying Java EE and BDD with Cucumber, Arquillian and Cukespace

Having written about the basics of using Cucumber in a Java project in my last blog article, I now would like to demonstrate how to use a similar setup in a Java EE web project with Arquillian and the Cukespace library. In the following tutorial, we’re going to write a full Java EE web application and add BDD-style tests to the project so that we’re able to test our business layer on the one hand and the user interface on the other hand using Arquillian Drone and Selenium. ...

Java EE: Setting up and Testing Form-Based JDBC Authentication with Arquillian and Maven

Especially when it comes to testing, setting up a decent environment for a secured Java EE web application isn’t always an easy thing to do. In the following tutorial I’d like to demonstrate how to create a secured web application using form-based authentication and a JDBC realm to fetch users and roles and how to run the application in an embedded container for testing and development. Additionally I’d like to show how to write and run integration tests to verify the security setup using a setup of Maven, Embedded GlassFish, Arquillian, jUnit and rest-assured. ...

Micro Benchmarking your Tests using JUnit and JUnitBenchmarks

I recently stumbled upon a nice framework that allows to convert simple JUnit tests into micro benchmarks named JUnitBenchmarks. It allows to set basic benchmark options and and to generate charts by adding some simple annotations and a test rule to your tests. One might argue if it is wise to mix the aspects, testing and benchmarking and I’d agree for sure – nevertheless I think this framework can be handy sometimes so let’s create some benchmarks using JUnit and JUnitBenchmarks.. ...

Running categorized Tests using JUnit, Maven and Annotated-Test Suites

Sometimes we need to classify the tests in a project and a possible solution to achieve this goal is to assign different categories to the tests. Often we’re doing this to separate the execution of fast-running and long-running tests or to run a specific set of tests that is only applicable in special situations. To run a specific set of categorized tests there are different options and in the following tutorial we’ll be covering two of them: by configuring the Maven Surefire Plug-in or by using a JUnit Test Suite and the JUnit annotations. ...

New features in JUnit 4.11

JUnit is one of the most popular testing frameworks out there. Version 4.11 has just been released and offers some nice improvements that you shouldn’t miss. Dependencies In older versions of JUnit there were two dependencies .. junit:junit contained an old version of hamcrest and could cause some nasty trouble .. junit:junit-dep just referenced hamcrest the maven way. Now with version 4.11 there is just junit:junit with clean references to hamcrest and junit:junit-dep is relocated to junit:junit. ...

Make your Tests more readable with custom Hamcrest Matchers

Everyday we’re writing tests for our software and sometimes we’re in a situation where we’re testing a specific type or object very often. Luckily Hamcrest allows us to create custom matchers by subclassing from a given variety of available matchers. Adding jUnit and Hamcrest First add the dependencies for JUniti and Hamcrest to your project’s pom.xml or alternative build system. <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.10</version> <scope>test</scope> </dependency> <dependency> <groupId>org.hamcrest</groupId> <artifactId>hamcrest-all</artifactId> <version>1.3</version> <scope>test</scope> </dependency> </dependencies> ...

Selenium WebDriver, Selenium Server and PageObjects by Example

A lot has changed since Selenium RC and WebDriver has given us a new syntax to write tests for our web pages. PageObjects add an abstraction to the pages under test and finally we’re able to programmatically start Selenium server instances and use them to run the tests. In the following tutorial, we’re writing some tests using PageObjects, WebDriver, Selenium Server and finally we’re even taking some screenshots of our tested web pages.. ...

Ordering your JUnit Rules using a RuleChain

JUnit Rules are a handy solution if one needs to alter test methods or wants to share common functionality between several test cases. JUnit 4.10 introduced a new class to order several rules according to our needs using a so called rule-chain. In the following example, we’re going to create a simple custom rule and afterwards bind several instances of it in a specified order to a test method. Adding JUnit Just one Maven dependency needed here – JUnit 4.10 ...

REST-assured vs Jersey-Test-Framework: Testing your RESTful Web-Services

Today we’re going to take a look at two specific frameworks that enables you to efficiently test your REST-ful services: On the one side there is the framework REST-assured that offers a nice DSL-like syntax to create well readable tests – on the other side there is the Jersey-Test-Framework that offers a nice execution environment and is built upon the JAX-RS reference implementation, Jersey. In the following tutorial we’re going to create a simple REST service first and then implement integration tests for this service using both frameworks. ...

Mocking, Stubbing and Test Spying using the Mockito Framework and PowerMock

Today we’re going to take a look at the Mockito framework that not only does sound like my favourite summer cocktail but also offers nice testing, mocking/stubbing, test-spying features and mock injections. After that we’re going to take a look on how to mock static or final classes by extending Mockito’s capabilities with PowerMock. Prerequisites We don’t need much for the following samples .. Java of course, Maven dependency management and that’s all .. ...
