Add tests to the collection:

Using the Postman MCP server, add tests to [workshop collection name].
For each request:
  1. Add a status code check (200 OK)
  2. Validate the response has a 'success' property set to true

Run the tests:

Claude Prompt: Run the "[workshop collection name]" collection and show me the test results.
