The original title is "Test Mobile AI Input by Capability, Not Device Category"

Short summary

Mobile AI testing should evaluate active capabilities and state transitions rather than device labels like phone or tablet. The article provides a concrete matrix mapping state changes—keyboard attachment, device unfolding, permission revocation, backgrounding, stylus-to-touch shifts—to expected preservation behaviors. It also specifies environment metadata and performance metrics to capture for reproducible, evidence-based testing.

• •Test capabilities (viewport, inputs, network, permissions) and transitions, not device categories
• •Concrete state-change matrix defines expected behaviors for streaming, composing, recording, and offline scenarios
• •Capture full environment envelope and specific timing metrics for reproducible test evidence
