  • Checked that there is not already provided the described functionality

Description

We should use Goss instead Testinfra to check:

• Default tomcat port is opened (8080)
• Default shutdown port is opened (8009) (and not opened if it's configured with '-1' value in other scenario). Check that configured shutdown command also works.
• Tomcat version
• Tomcat user exists
• Tomcat service is running
• Tomcat is up and running (HTTP check) with sample.war
• Pre-installed folders are deleted if are configured as 'not deployed' (other scenario IMHO)
• Extra configuration is copied when is provided as file or template under playbook_dir
