# Connect Tosca to SeaLights

When you run a test in Tosca, Tosca reports the test execution to SeaLights, and SeaLights uses it to report on the test coverage for the ABAP components in your SeaLights app’s latest Build Modification. This integration requires you to connect Tosca to SeaLights, as described in the Tosca Command manual [here](https://documentation.tricentis.com/tosca/2510/en/content/sealights_integration/sealights_integration_overview.htm), and the Tosca Cloud manual [here](https://documentation.tricentis.com/tricentis_cloud/en/content/admin_guide/sealights_integration.htm). SeaLights supports Tosca Commander versions 2025.1.4, and Tosca Cloud 1.0.

You’ll also need to optimize your Tosca test run with SeaLights as described [here](https://documentation.tricentis.com/tosca/2510/en/content/sealights_integration/sealights_optimization.htm) for Tosca Commander, and [here](https://documentation.tricentis.com/tricentis_cloud/en/content/admin_guide/sealights_integration.htm?Highlight=sealights#optimize_sealights) for Tosca Cloud.
