/proof-strategy

ProofQuality & Testing

Designs a test strategy for a project: analyzes what tests already exist and at what layer, identifies critical user paths with no coverage, recommends the right mix of unit, integration, and E2E tests given the project's specific risk profile and release cadence, and produces a testing plan with priority order and rationale.

When to use

When starting a new project and want to establish the right testing approach before code is written. When test coverage exists but feels wrong: too slow, too brittle, testing implementation instead of behavior, or missing the scenarios that actually fail in production. When the team disagrees on testing philosophy and needs a shared reference point.

AI Test Strategy and Coverage Plan

Most teams pick test types by habit. /proof-strategy analyzes the project, identifies critical paths with no coverage, and produces a calibrated unit/integration/E2E mix.

/proof-e2e

Builds E2E test suites with Playwright, Cypress, or Selenium focused on user journeys rather than implementation. Covers the critical paths that must work for the product to deliver its core value, with stable selectors that survive UI changes, proper async waits, and CI integration that runs on every merge.

When critical user flows like sign-up, checkout, o…

ProofQuality

/proof-api

Builds API test suites covering endpoint behavior (correct status codes, response schema validation, error cases), contract testing to catch breaking changes before they reach consumers, and load testing to establish baseline performance at expected traffic levels. Works for REST, GraphQL, and gRPC.

When an API needs systematic test coverage before …

ProofQuality

/proof-audit

Audits test suite health: identifies flaky tests and their root causes, finds tests that take disproportionately long and explains why, measures coverage gaps on critical code paths, and reviews testing patterns for anti-patterns like testing implementation details or using inadequate assertions that pass on wrong behavior.

When CI is unreliable enough that team members hav…
