+py.tests tests
+```
+
+Run the tests in parallel:

 ## Web UI links
 
 To access the components web UI links on your host , you will have to setup the IP adresses with their respective FQDN in `etc/hosts`, introduce the SSL certificate into your browser and install and configure Kerberos client. Luckely a container image has been created where verything is alraedy setup. However, the SSl certificate which is created with the `ansible_collections/tosit/tdp_prerequisites/playbooks/certificates.yml` playbook must already present in `files/tdp_getting_started_certs` otherwise the build will fail.
