+#### Testing the code
+
+All software required to run tests is installed in the virtual machine. 
+In order to run all tests you have to execute the following commands:
+ 
+    vagrant ssh -c /vagrant/test/php/runtests
+    vagrant ssh -c /vagrant/test/php/checkswag
+    vagrant ssh -c /vagrant/test/js/runtests
+    vagrant ssh -c /vagrant/test/js/checkswag
+    vagrant ssh -c /vagrant/test/frontend/runtests
+
+`runtests` will execute unit and regression tests and `checkswag` will report
+code style issues.
