Start by locating the Cupcake Ipsum Generator entry point and checking the repository's existing Jest setup. Define tests for rendering, interactions, props, state, and any significant workflow, then run the Jest suite locally and in the CI/CD pipeline. Done means the tests pass and documentation explains how to run them.
