In the Xray settings, you can enumerate the Jira projects that have requirements.
For these projects, the requirement's issue screen will display the Requirement Status custom field (which indicated the calculated status for the requirement) and a Test Coverage panel, from where the user is able to see all Tests that validate the requirement or create new, linked Tests to validate the requirement.
Some reports are only be available for Requirement Projects; thus, the Xray Reports project icon may or may not appear on the left side bar.
Search for existing projects
You can search for existing projects to see if they're being handled as requirement projects or not. In the following example, you can see that "Calculator" (CALC) is a requirement project.
Define a project as a "Requirement Project"
You can define a project as being a "requirement project" using the Add Project action. Auto-complete helps you find proper projects.
Xray will add the Requirement Status custom field to all the requirement issue types (as defined in the Issue Type Mapping settings).
Remove the "Requirement Project" definition
You can remove a project from the list of Requirement Projects by using the Delete action within the row of a given project.
In this case, Xray will remove the Requirement Status custom field from all the requirement issue types (as defined in the Issue Type Mapping settings).
