Endigest AI Core Summary
Agent-driven E2E testing validates goal achievement rather than predefined UI journeys, offering adaptability but with distinct cost and reliability tradeoffs.
•Agent-based tests allow flexible UI navigation paths to reach goals, unlike deterministic tests enforcing specific click sequences
•Playwright MCP achieved near-zero failures on simple flows and 0-12% on complex scenarios, while CLI-based agents showed 12-20% failure rates
•Generated Playwright tests ran fastest at ~3 minutes but failed on 48% of complex workflows due to UI state variability
•Agent-driven execution costs $15-30 per run with 10+ minute execution times; MCP approaches use 3.5-3.8M tokens versus 5.7-7M for CLI and code generation
•MCP maintains persistent DOM context enabling better step reuse, while CLI rebuilds state at each step causing accumulated failures
