EasyMock - Environment Setup


Advertisements


EasyMock is a framework for Java, so the very first requirement is to have JDK installed in your machine.

System Requirement

JDK 1.5 or above.
Memory no minimum requirement.
Disk Space no minimum requirement.
Operating System no minimum requirement.

Step 1: Verify Java Installation on Your Machine

Open the console and execute the following java command.

OS Task Command
Windows Open Command Console c:\> java -version
Linux Open Command Terminal $ java -version
Mac Open Terminal machine:~ joseph$ java -version

Let's verify the output for all the operating systems:

OS Output
Windows

java version "1.6.0_21"

Java(TM) SE Runtime Environment (build 1.6.0_21-b07)

Java HotSpot(TM) Client VM (build 17.0-b17, mixed mode, sharing)

Linux

java version "1.6.0_21"

Java(TM) SE Runtime Environment (build 1.6.0_21-b07)

Java HotSpot(TM) Client VM (build 17.0-b17, mixed mode, sharing)

Mac

java version "1.6.0_21"

Java(TM) SE Runtime Environment (build 1.6.0_21-b07)

Java HotSpot(TM)64-Bit Server VM (build 17.0-b17, mixed mode, sharing)

If you do not have Java installed, To install the Java Software Development Kit (SDK) click here.

We assume you have Java 1.6.0_21 installed on your system for this tutorial.

Step 2: Set JAVA Environment

Set the JAVA_HOME environment variable to point to the base directory location where Java is installed on your machine. For example,

OS Output
Windows Set the environment variable JAVA_HOME to C:\Program Files\Java\jdk1.6.0_21
Linux export JAVA_HOME=/usr/local/java-current
Mac export JAVA_HOME=/Library/Java/Home

Append the location of the Java compiler to your System Path.

OS Output
Windows Append the string ;C:\Program Files\Java\jdk1.6.0_21\bin to the end of the system variable, Path.
Linux export PATH=$PATH:$JAVA_HOME/bin/
Mac not required

Verify Java Installation using the command java -version as explained above.

Step 3: Download EasyMock Archive

To download the latest version of EasyMock click here.

Save the zip folder on your C drive, let's say, C:\>EasyMock.

OS Archive name
Windows easymock-3.2.zip
Linux easymock-3.2.zip
Mac easymock-3.2.zip

Step 4: Download EasyMock Dependencies

Download the latest version of cglib jar file from https://github.com/cglib/cglib/releases and copy it onto C:\>EasyMock folder. At the time of writing this tutorial, the latest version was 3.1.

Download the latest version of objenesis zip file from http://objenesis.org/download.html and copy it onto C:\>EasyMock folder. At the time of writing this tutorial, the latest version was 2.1. Extract objenesis-2.1.jar to C:\>EasyMock folder

Step 5: Set EasyMock Environment

Set the EasyMock_HOME environment variable to point to the base directory location where EasyMock and dependency jars are stored on your machine. The following table shows how to set the environment variable on different operating systems, assuming we've extracted easymock-3.2.jar, cglib-3.1.jar, and objenesis-2.1.jar onto C:\>EasyMock folder.

OS Output
Windows Set the environment variable EasyMock_HOME to C:\EasyMock
Linux export EasyMock_HOME=/usr/local/EasyMock
Mac export EasyMock_HOME=/Library/EasyMock

Step 6: Set CLASSPATH Variable

Set the CLASSPATH environment variable to point to the location where EasyMock and dependency jars are stored. The following table shows how to set the CLASSPATH variable on different operating systems.

OS Output
Windows Set the environment variable CLASSPATH to %CLASSPATH%;%EasyMock_HOME%\easymock-3.2.jar;%EasyMock_HOME%\cglib-3.1.jar;%EasyMock_HOME%\objenesis-2.1.jar;.;
Linux export CLASSPATH=$CLASSPATH:$EasyMock_HOME/easymock-3.2.jar:$EasyMock_HOME/cglib-3.1.jar:$EasyMock_HOME/objenesis-2.1.jar:.
Mac export CLASSPATH=$CLASSPATH:$EasyMock_HOME/easymock-3.2.jar:$EasyMock_HOME/cglib-3.1.jar:$EasyMock_HOME/objenesis-2.1.jar:.

Step 7: Download JUnit Archive

Download the latest version of JUnit jar file from Github. Save the folder at the location C:\>Junit.

OS Archive name
Windows junit4.11.jar, hamcrest-core-1.2.1.jar
Linux junit4.11.jar, hamcrest-core-1.2.1.jar
Mac junit4.11.jar, hamcrest-core-1.2.1.jar

Step 8: Set JUnit Environment

Set the JUNIT_HOME environment variable to point to the base directory location where JUnit jars are stored on your machine. The following table shows how to set this environment variable on different operating systems, assuming we've stored junit4.11.jar and hamcrest-core-1.2.1.jar at C:\>Junit.

OS Output
Windows Set the environment variable JUNIT_HOME to C:\JUNIT
Linux export JUNIT_HOME=/usr/local/JUNIT
Mac export JUNIT_HOME=/Library/JUNIT

Step 9: Set CLASSPATH Variable

Set the CLASSPATH environment variable to point to the JUNIT jar location. The following table shows how it is done on different operating systems.

OS Output
Windows Set the environment variable CLASSPATH to %CLASSPATH%;%JUNIT_HOME%\junit4.11.jar;%JUNIT_HOME%\hamcrest-core-1.2.1.jar;.;
Linux export CLASSPATH=$CLASSPATH:$JUNIT_HOME/junit4.11.jar:$JUNIT_HOME/hamcrest-core-1.2.1.jar:.
Mac export CLASSPATH=$CLASSPATH:$JUNIT_HOME/junit4.11.jar:$JUNIT_HOME/hamcrest-core-1.2.1.jar:.
