Mockito 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 Mockito-All Archive
To download the latest version of Mockito from Maven Repository click here.
Save the jar file on your C drive, let's say, C:\>Mockito.
OS Archive name
Windows mockito-all-2.0.2-beta.jar
Linux mockito-all-2.0.2-beta.jar
Mac mockito-all-2.0.2-beta.jar
Step 4 − Set Mockito Environment
Set the Mockito_HOME environment variable to point to the base directory location where Mockito 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 mockito-all-2.0.2-beta.jar onto C:\>Mockito folder.
OS Output
Windows Set the environment variable Mockito_HOME to C:\Mockito
Linux export Mockito_HOME=/usr/local/Mockito
Mac export Mockito_HOME=/Library/Mockito
Step 5 − Set CLASSPATH Variable
Set the CLASSPATH environment variable to point to the location where Mockito jar is 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%;%Mockito_HOME%\mockito-all-2.0.2-beta.jar;.;
Linux export CLASSPATH=$CLASSPATH:$Mockito_HOME/mockito-all-2.0.2-beta.jar:.
Mac export CLASSPATH=$CLASSPATH:$Mockito_HOME/mockito-all-2.0.2-beta.jar:.
Step 6 − 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 7 − 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 8 − 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:.
