Testing Rendering Behavior Without Guesswork

Rendering-heavy systems need tests that assert structure, route behavior, and expected integration outcomes.

Structural Assertions First

Prefer selectors and clear attribute checks for generated HTML structure.

Integration Smoke Coverage

Verify shell wiring, route resolution, and pagination behavior in controller integration tests.

Regression Signal

Small focused tests catch API drift early and keep demo surfaces trustworthy.

Keep Tests in the Same Workstream

Feature and behavior changes should ship with matching tests, not deferred coverage.
