As we maintain a JIRA project and a Testlink project by Gazelle application, we need to configure a new Issue Tracker in Testlink for each new Testlink project. In this way, when executing the tests, we will be able to report the bugs directly from Testlink with a reference to the test case.
In the Desktop part of Testlink, click on "Issue Tracker Management" in the System panel (top-left corner). Then it the "create" button and configure the tool as shown in the screenshot below. For security reason, we have hidden the username and password parameters. Refer to another Issuer Tracker definition or ask the Gazelle administrator to get them. The JIRAKEY refers to key which uniquely identified a project in JIRA. Then, to link the Issue Tracker to your Testlink project, edit your project configuration
The screenshot below shows the basic definition of a test project in TestLink.
