You can define parameters by entering the ${parametername} placeholders to Description or Name fields.

To configure parameter values, add a new wiki field with the name Test Parameters to the configuration for test case or test set trackers. This field stores the configured values or the reference to the Excel sheet. Open the configuration screen and add a new custom field as shown in the following image:

The permissions for this field are typically set so that the Test Engineer and Stakeholder roles have read and write permissions, as they will configure the parameter values. The Tester role should have at least read permission, otherwise the configured parameters won't be available during test runs. To use an Excel sheet in the Document Manager, set the read permissions for all testers to access the parameter files.

The default permission configuration of the Test Parametersfield appears as shown in the image:

For the test run tracker and bug tracker, there is no need for configuration. The parameter values are stored in the description of these issues, these fields are writable by testers.
