In Salesforce, every Apex Trigger must have at least one line of code covered by a test class before it can be deployed to production.

For DSP triggers, each Apex Trigger contains a single line:

pushtopics.TriggerServices.execute();

To meet the coverage requirement, write a test class that performs a DML operation (such as an insert, update, or delete) on the object tied to the trigger. This will invoke the trigger and automatically cover the line.

For deployment coverage, a simple DML test is enough. If you also want to validate the business logic defined in Executables, extend your test classes to check the expected outcomes.
