consumes more and more memory • One test case panics, crashes all the other AT jobs • High maintenance due to programming language 大公司 API 测试的需求 软件测试工具 • 模拟数据规则 • 自动化测试 • Use rust to compile wasm implicate the others • Can be compiled from many programming language • Store wasm files prevent maintenance issues API 测试 - Wasm Mock Server 用 rust, 好处多 软件测试工具 • Url param ?loop=2 • index 取 _i • Command
