Running JUnit test cases from Jenkins or Maven for WebSphere MQ causes 2495 error

I was trying to run JUnit test cases using Maven and from jenkins and I was continuously getting the following error - 
A WebSphere MQ Error occured : Completion Code 2 Reason Code 2495
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.477 sec

export LD_LIBRARY_PATH=/opt/mqm/java/lib/:$LD_LIBRARY_PATH

Creating users for apache-tomcat
conf/tomcat-users.xml contains the users. To create a manager user to manage tomcat add the following details -

<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<user username="tomcat" password="s3cret" roles="manager-gui,manager-script"/>

This will create the user tomcat with password s3cret.
