Testing a Mapper

Testing allows you to verify the mapper’s transformation logic using real or saved messages.
You can perform tests directly within the Mappings and Test Panel.

How to Test a Mapper​

  1. Open your desired mapper.
  2. Select or upload a test message (JSON format).
  3. Click the refresh button or Full Test to apply the mapper transformation.
  4. Review the Test Result section to see the output message.

You can test with messages either:

  • Retrieved from connected endpoints, or
  • Uploaded manually via Saved Messages.

Test Message Navigation​

The test interface provides several controls to help you explore and refine your mappings.

Test message navigation

  • Next / Previous Message: Browse available messages that match the mapper’s message type.
  • Refresh Message: Reprocesses the current message without resending it. (No API calls are made.)
  • Filter Message: Filter by content to locate specific test data.
  • Full Test: Executes a full test, including API calls within the mapper.

Fields displayed in bold are those affected by one or more mappings.
For example, in the screenshot below, the ticket_id field appears bolded because it has been modified by an active mapping.
