传统的截图方法在 AI 测试工具中普遍使用，但存在高成本和延迟问题。每个截图的大小超过 100KB，处理时需要消耗大量的 tokens，并且需要视觉识别来定位元素，分析延迟在 500ms 到 2s 之间。相比之下，语义快照通过发送结构化描述的方式，能够在 1ms 内提取完整的用户界面结构，为 AI 提供机器可读的图像，显著降低了成本。此外，最新功能还支持自动检测表单验证规则，进一步提升了测试效率。

How AI Semantic Snapshots Replace Screenshots for E2E Testing
Traditional screenshot methods are commonly used in AI testing tools but come with high costs and latency issues. Each screenshot exceeds 100KB in size, requires significant token consumption for processing, and involves visual recognition to locate elements, resulting in analysis delays ranging from 500ms to 2s. In contrast, semantic snapshots send structured descriptions of interactive elements, allowing for the extraction of the complete UI structure in just 1ms, providing a machine-readable image for a fraction of the cost. Additionally, the latest feature includes automatic detection of form validation rules, further enhancing testing efficiency.
