systematic-testing

Bottom-up validation tests each architectural layer in isolation before integration. By starting with domain plugins and ascending to the dashboard UI, it isolates failures at the source to reduce cross-layer debugging time.

You test API proxies and browser traffic by following a strict gate-driven sequence: validate the domain plugin first, then the API proxy, then browser traffic capture, ensuring each lower layer is healthy before ascending to the next.

Dashboard UI failures despite a healthy API proxy often indicate broken browser traffic capture or UI data flows. Gate-driven per-layer validation isolates this by providing explicit diagnostic and remediation steps for the specific failed layer.

Validating dashboard UI data flows without testing domain plugins first skips the required gate-driven sequence. You must enforce the strict L1 to L4 progression to ensure lower layers are healthy before ascending to UI validation.

The best way to structure end-to-end testing across multiple layers is applying a strict gate sequence: validate domain plugins, API proxies, browser traffic capture, and dashboard UI independently in order, with clear failure remediation guidance at each step.
