Background and Motivation

Traditional web application testing has long faced a core dilemma: test scripts are fragile and maintenance costs are high. Whenever the UI undergoes minor changes, test scripts based on CSS selectors may fail, leading to a lot of manual repair work. At the same time, large language models (LLMs) have shown strong understanding and reasoning capabilities, but how to effectively integrate them into the testing workflow remains an open question.

Agentic Testing MCP emerged as a solution; through the Model Context Protocol (MCP), an open standard protocol, it deeply integrates LLM capabilities with browser automation, creating a new AI-driven testing paradigm.

Project Overview

Agentic Testing MCP is an open-source testing framework based on TypeScript, with its core architecture centered around three layers:

Section 05

1. LLM Agent Layer

The AI client interacts with the underlying system through the Test Orchestrator. This layer is responsible for understanding test intentions, formulating verification strategies, and converting high-level instructions into executable actions.

2. MCP Protocol Layer

As a bridge connecting LLMs and tool capabilities, the MCP server exposes three core tools:

  • verify_page: Verifies whether the page state meets the expected conditions
  • analyze_context: Analyzes the page context and extracts interactive elements
  • generate_test_plan: Generates a context-aware test plan based on page analysis

3. Browser Automation Layer

The underlying layer implements cross-browser automation based on Playwright, supporting mainstream browsers such as Chrome, Firefox, and Safari.

Context-Aware Verification

Unlike traditional testing frameworks that rely on fixed selectors, Agentic Testing MCP allows LLMs to understand the page structure. When verifying the page state, the system not only checks whether elements exist but also analyzes the relationships, visibility, and interaction states between elements. This semantic-level understanding makes tests more resilient and able to adapt to reasonable UI changes.
