 5. If you do not feel comfortable using Erlang configuration file, you can use command line arguments and flags in format of `/epp_proxy/rel/bin/epp_proxy -epp_proxy tls_port 444`, where `-epp_proxy` is name of application,
    followed by configuration parameter name and value.
 
+Testing
+----
+The application comes with test suite written with common_test. For integration
+tests, there is a small Roda application located in apps/epp_proxy/priv/test_backend_app.
+It has been written with Ruby 2.6.3
+
+You need to start it before running the test suite. To start it as a deamon,
+from the root folder of the project, execute:
+
+```bash
+$ /bin/bash -l -c "cd apps/epp_proxy/priv/test_backend_app && bundle install"
+$ /bin/bash -l -c "cd apps/epp_proxy/priv/test_backend_app && bundle exec rackup --pid pidfile -D"
+```
+
+After you finish testing, you can stop the process by reading the stored pid:
+
+    $ kill `cat apps/epp_proxy/priv/test_backend_app/pidfile`
+
