+Segment provides these 2 testing tools to enable you to test your connections between Segment and your destination:
+* [Event Tester](#event-tester): Test all of your enabled mappings within a destination. 
+* [Mappings Tester](#mappings-tester): Test a single mapping configuration for your destination. 
+
+Both testing tools share the same underlying testing infrastructure, which ensures consistent results across your testing workflows. The results from both testers display API requests, responses, and success/failure status to help you diagnose any issues.
+
+You can use the Event and Mappings Tester for these products: 
+* [Connections](/docs/connections/)
+* [Linked Audiences](/docs/engage/audiences/linked-audiences/)
+* [Linked Events](/docs/unify/data-graph/linked-events/#testing-with-linked-events-enrichments)
+* [Reverse ETL](/docs/connections/reverse-etl/)
+* [Journeys](/docs/engage/journeys/)

+When you add a destination and create a mapping in Connections, Reverse ETL, Linked Audience, and Journeys, you can test the specific mapping using the Mappings Tester. The Mappings Tester only tests a single mapping at a time and you can edit field values before initiating a test. This helps you verify that your configured mapping works as expected.
+
+Use the Mappings Tester when you need to:
+* Verify a single mapping configuration
+* Edit field values before testing a mapping
+* Troubleshoot a specific mapping that isn't working as expected
+
+### Using the Mappings Tester
+To use the Mapppings Tester:
+1. Navigate to the product (Connections, Reverse ETL, Linked Audience, or Journeys) you want to test the mapping for. 
+2. Select the destination that has the mapping you want to test.
+3. Select **Edit mapping**. 
+4. Edit any values in the **Send test record** section.
+5. Click **Send test event**.

+The [Event Tester and Mappings Tester](/docs/connections/test-connections/#) support testing enrichments from Linked Events, allowing you to verify that entity data is correctly attached to your events before they reach destinations. When you have Linked Events configured, these enrichments appear in your test payload, showing you exactly how profile traits will add to your events.
