Junit 4
A set of tools to optimize the creation and maintainability of JUnit tests.
Write less, test more! The main feature of JUnit-Tools is to generate JUnit test-elements (packages, classes, methods, test-cases, mocks) depending on an existing java-class and logic. It supports the Test-After Development: Create JUnit-tests after writing or modifying application code. Other input-channels (e.g. UML-models) for the generation of test-elements to support Test-Driven Development are possible but not available yet. JUnit-tests usually have a similar structure: Create the preconditions, run the class under test, validate the postconditions. The created test-elements for the classes and methods should have the same name-conventions to find easily the corresponding tests. These are good reasons for a generator. The main difference to other tools is, that JUnit-Tools is complete open source and that it is easy to adapt the structure and generated output to the own needs and requirements. There are many extension points and interfaces to change and contribute the base-implementations. An integration for the IDE eclipse is available and it's easy to install, set up and run the tools. If you have any questions or issues, please feel free and send us an email: support@junit-tools.org We are also happy about feedback and any ideas to improve the JUnit-Tools.

- [Voiceover] Let's review how to downloadand install JUnit.To obtain the most recent version of JUnit,you can download and install it from this website atjunit.org/junit4/As you can see, at the time of this seriesthey are working on JUnit 5.So check for the latest version before downloading.Here it says 'Work on JUnit 5 - Milestone 1 has started.'From this page we can download the most recent versionof the JUnit JAR file.
Let's click on 'Download and Install'under the 'Welcome.'As you can see, under the 'Plain-old JAR,'where JAR stands for Java Archive,we can download the following JARsand put them into our test classpath.There are two files here:junit.jar and hamcrest-core.jarThe Hamcrest file is used in the example providedby this JUnit website, but if you're not goingto use any of its classes and methods,you don't need to download it.
The Hamcrest framework extends the capabilitiesof JUnit testing to include what they call Matchers.In other words, you now have a type of assert statementthat says 'assert that something equals something else,'which is a little different from the assert in JUnit.For this tutorial I'm concentrating on JUnit,but the Hamcrest extension is worth taking some timeto review and becoming familiarwith its adding capabilities.You can get more information here athamcrest.org/JavaHamcrest/For now, I'm gonna download these two files.
How To Install Junit
I'll click on junit.jar and I'll downloadthe most recent version 4.12.On the right hand side under downloadI'm going to download the JAR file.I have a message. It says 'This type of filecan harm your computer.'I'm going to say 'Keep'.And now I'll go back and downloadthe Hamcrest-coreJAR file as well.I'm gonna do the same thing and getthe most recent version of the JAR file.I have the same message. I'll click 'Keep'.
Now both files are downloaded.Next, I'm gonna move them from my download folderto a new folder I'll create called 'Junit-example'.Let's do that now.I'm gonna use 'File Explore' to create my new folderand move these files.So on 'File Explorer' I'm gonna go to my 'C' drive.Users/ProducerI'm gonna right click and create a new folder.The new folder's called 'JUnit-example'.
Now, I'll go to my downloadsand I'm gonna highlight both filesright click and copy.I'm gonna go back over to my 'JUnit-example' folderand I'm gonna right click and paste.That way I can go ahead and create a programin this folder to show you how to use the 'JUnit' framework.Once these files are downloadedyou do need to make sure you take timeto update your class path to pointto the 'JUnit-4.12.JAR' location.
Now I'd like to go back to the download page.If I scroll down you'll see there's alsoinformation about how to use 'JUnit' with 'Mavin'.If you're using 'Mavin' for your projectsyou can add the dependency for 'JUnit' bysimply including the group ID 'JUnit'the artifact ID 'JUnit' andin this case, my version is 4.12.That needs to match the versionthat you downloaded.And the scope of this dependencyshould say 'test'.
Junit Download For Eclipse
At this point, that's all I need to doto be able to use 'JUnit'.'JUnit' can be used as part of an 'IDE',an integrated development environment,or from the command line.If you run from the command linethat's one of the reasons we needed to downloadthe two 'JAR' files.
