block-testing

To set up Jest unit tests for EDS blocks, you bootstrap test infrastructure with Jest and Babel config, then co-locate tests under blocks/{name} to maintain robust suites for complex logic.

Keeper tests are maintained long-term to verify robust block logic, while throwaway tests validate temporary data transformation or state changes before being discarded, ensuring a maintainable test suite.

You mock aem.js and analytics utilities by applying standardized mock patterns provided for common scripts, isolating block logic during Jest test automation without triggering actual external dependencies.

Yes, the Jest testing pattern specifically applies to EDS blocks with event handling, data transformation, and complex state management, providing bootstrapped infrastructure to verify logic accurately.

The best way to organize Jest test files is co-locating them within the blocks/{name} directory structure, which keeps tests maintainable and closely aligned with the specific block's logic.
