+Testing
+-------
+
+For performing all ci-tasks you have to add all dev-dependencies. Do so like this
+
+    php composer.phar update
+
+this adds all necessary tools like phing, phpunit, etc.
+
+After that you can perform the task with the following command:
+
+    phing
+
+Be aware that you will need several programs like java and mysql to setup a solr-index and a database-store in order to
+test the components of vufind that communicate with them.
+
+You might need to set up the mysql-user credentials, if case they do not agree with your mysql root-users credentials.
+You can do that by providing optional parameters like that
+
+    phing -Dmysqlrootpass=''
+
+Do so if you have no rootpassword set. The default password is 'password'.
