Bugzilla is a famous free bug tracker, sometimes abused as a general issue management system. Still, Zabbix can monitor the status of software tests and open new tickets if, for example, compilation fails. The following would be configured as the message body:

@{TRIGGER.NAME} 
@product = <some existing product> 
@component = <some existing component> 
@version = 1.8 
{DATE} - {TIME} 
{TRIGGER.NAME}. 

The From address is used to determine the user account that is creating the bug report.
