Background

The objective was not just to automate tests faster, but to build an engineering capability where prompt engineering, MCP-enabled tooling and framework guardrails combine to stay maintainable as the product, flows and test estate evolve. Traditional automation approaches often become slow to scale, fragile to maintain and inconsistent across teams. The client needed a framework that could speed up script creation without introducing brittle test assets or uncontrolled AI output, while making AI prompts specific enough to produce technically sound, business-aligned scripts. The framework had to support the full lifecycle of automation delivery: planning, script generation, healing of failing tests, reusable design patterns, consistent verification and structured results recording.

Solution

Fimatix designed a framework that combines proven automation engineering patterns with disciplined AI prompt engineering. Dedicated planner, generator and healer prompts define Copilot’s role, constraints and output standards in detail. UI elements are abstracted into maintainable page classes, while higher-level user actions are grouped into reusable flows. Standardised step logging and wrapped verification rules create consistent execution evidence.

Framework Architecture

The implementation emphasised clear separation of responsibilities. Test scripts are automatically generated and kept in one place. Each application page is defined once. Reusable utilities handle common actions. AI prompts are managed centrally, so tests can be created and improved in a controlled way. Test results are recorded automatically, and test plans are produced in a readable format. Engineering guardrails include reusable locator rules, driver methods, and structured verification.

Delivery Model

Delivery Model The framework was designed to support the end-to-end automation lifecycle. Copilot acts as a planner within a Playwright MCP-enabled workflow, navigating the application and producing Markdown test plans. Structured prompts generate Playwright tests and page objects directly into the project. Failing tests can be healed while preserving business intent. Parameterised helpers, page abstraction, flow models and reusable prompt patterns allow new journeys to be added with less duplication.

Illustrative Business Outcomes

This approach gives teams faster delivery without sacrificing predictability. Outcomes include 50-70% faster test asset creation, 30-45% lower maintenance effort, 2-3x increase in reusable coverage growth, and 100% structured verification discipline.

Outcome

The finished framework gives delivery teams a practical route to modern automation: faster creation, clearer structure, stronger reuse and a better foundation for sustainable AI adoption in testing. The client gains a modern automation framework built on Playwright MCP-enabled tooling, prescriptive prompt engineering assets, cleaner separation between test logic, UI abstraction and utility methods, and improved confidence in regression execution and results reporting.
