AI Test Automation Architecture: The 3-Layer System
AI Test Automation Architecture: The 3-Layer System AI test automation architecture is the system that tells AI what to test. It also defines how to run tests and prove the result. I split it into three layers: orchestration, execution, and evidence. Without all three, AI testing becomes prompt output with no production gate.

The MCP Ecosystem Just Collapsed Into Playwright
AI agents made it worse. They still get stuck at login screens. This month, that changed. MCP (how AI talks to tools) is changing how we test. Two teams at Microsoft shipped a fix. They released two ways to share your browser with AI. Playwright core added browser.bind(). The CLI team added an MCP Bridge. Both land in the same month. This is not a test. It is the new way.
