Lastest — Visual Regression Testing Agent

What problem does it solve?

Lastest helps you detect and manage UI regressions by recording browser flows, generating resilient visual tests, running them, and classifying screenshot diffs so you can approve or auto-fix breakages faster.

Core Features & Use Cases

• Trigger test builds & track status: Use MCP tools to start runs and poll build progress until results (including pass/fail and diff outcomes) are ready.
• Diagnose visual changes with AI classification: Inspect visual diffs with AI summaries (e.g., insignificant/noise vs meaningful changes) and decide whether to approve baselines or reject them.
• Create and heal tests automatically: Generate new tests from a URL/prompt and auto-fix failing tests via an AI healer when the UI changes.
• Coverage visibility: Retrieve coverage by functional area and route to identify what’s already tested versus missing.

Quick Start

Start by installing and connecting the MCP server using the command provided in the skill instructions, then call lastest_run_tests to create a build and follow with lastest_get_build_status until diffs are available.
