SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Validates that an explicit action-spec engine correctly performs deterministic HTTP requests and evaluates success or failure rules against JSON responses.

Core Features & Use Cases

Deterministic health check action: Verifies an API returns a successful JSON field match for a known endpoint.
Strict failure case: Intentionally expects an incorrect JSON value to confirm the parser surfaces SUCCESS_RULE_FAILED behavior.
Playwright validation fixture: Provides a stable, repeatable action payload for testing request/response matching, evidence, TTL, and security constraints.

Quick Start

Use the skill-actions-explicit-fixture payload to run deterministic Playwright checks that confirm both passing and intentionally failing JSON rule evaluations for GET /api/health.

FAQPage Schema

How do I validate JSON health check responses deterministically in Playwright?▼

Deterministic JSON health check validation in Playwright executes explicit HTTP requests and applies strict JSON path/value comparisons to verify API responses. It checks both passing and strict-fail scenarios for the same health endpoint to confirm correct behavior.

What is an explicit action specification for API testing?▼

An explicit action specification for API testing is a deterministic payload that defines HTTP requests, method allowlisting, same-origin constraints, and evidence production fields. It evaluates success or failure rules against JSON responses to validate health endpoints.

Can I test strict failure scenarios for the same API health endpoint?▼

Yes, you can test strict failure scenarios for the same API health endpoint by intentionally expecting an incorrect JSON value. This confirms the parser surfaces the SUCCESS_RULE_FAILED behavior during automated Playwright validation workflows.

Does this API testing fixture require transport metadata and security constraints?▼

Yes, the API testing fixture requires transport metadata, method allowlisting, and same-origin constraints. It also mandates evidence production fields and strict JSON path/value comparisons to determine health check outcomes securely and deterministically.

Why does my explicit API health check return SUCCESS_RULE_FAILED?▼

An explicit API health check returns SUCCESS_RULE_FAILED when the JSON response value does not match the expected strict comparison rule. This intentional mismatch verifies the parser correctly surfaces failure behavior for incorrect health endpoint values.
