_ Prerequisite

(Mandatory)

• Java SDK installation

(Optional)

The explanation in this page assumes the following.

• Eclipse installation (You can refer Overall/Eclipse)
• Maven installation (You can refer Overall/Maven)
• Cygwin instattion (You can refer Overall/Cygwin)

_ Install&Setup

Step.1

(We can use maven)

_ HowToUse

_ Create project.

Step.1

Launch Cygwin.

Step.2

Create the most simple maven project.

$ mvn archetype:create \
 -DgroupId=org.test \
 -DartifactId=project

Step.3

Sample production code App.java and AppTest.java will be created. You can execute testing by the following command.

$ mvn test

_ Import mvn project to eclipse

Step.1

Luanch eclipse.

Step.2

Select File -> Import.

Step.3

Select "Existing Maven Projects" and click "next" button.

Step.4

Click "Browse" button and select created maven project folder.

Step.5

Click "Finish" button. And you have imported eclipse project.

_ Prepare source code.

Step.1

Create sample production code, "Calc" as follows. sample code - Calc

Step.2

Select "File"->"New"->"JUnit Test Case" (lower one).

Step.3

Select "New JUnit 4 test" and click "Finish" button.

Step.4

When the JUnit 4 is not on the build path, eclipse ask if we setup it or not. Here, we choose "Not now" and click "OK" button. We will use maven later for this.

Step.5

Open POM.xml and edit it as following.

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.8.1</version>
  <scope>test</scope>
</dependency>

sample code - POM.xml

Step.6

Execute the following command. Maven download JUnit4 and setup it to the build-path based on the description in POM.xml.

$ cd <Maven project directory>
$ mvn test

Now we have JUnit in project, too.
