A passing test count says little about a web product if the tests do not observe the boundary most likely to fail. Pure rules, database transactions, API contracts, browser tasks, and loaded traffic each reveal different defects. The case-inspection service gives these checks a shared workload: a reviewer searches, opens, edits, and resolves a case while requests sometimes fail and traffic sometimes rises. The objective is a compact evidence set that explains behavior and recovery, not a collection of snapshots that merely repeat the current implementation.
Topics in this track
- Test Boundaries and Evidence Selection — Place checks where each failure can be observed rather than repeating one assertion at every layer.
- Deterministic Test Doubles and Fault Injection — Control failure timing without erasing the integration behavior the product depends on.
- Accessibility and Visual Regression Checks — Check task usability, keyboard behavior, and stable layout with evidence beyond a screenshot.
- Load Tests and Capacity Budgets — Model a realistic request mix and stop a release when latency or errors cross agreed limits.
Prerequisite paths
Tests across boundaries: assert behavior, not implementation text; Browser Journey and Fault-Injection Tests; Page performance: budget the critical path and reserve layout space.
