工具: RESTler
功能: 分析API说明并生成请求sequence
方法:1. inferring dependencies among request types declared in the Swagger specification (e.g., inferring that a resource included in the response of a request A is necessary as input argument of another request B, and therefore that A should be executed before B),
2. analyzing dynamic feedback from responses observed during prior test executions in order to generate new tests (e.g., learning that “a request C after a request sequence A;B is refused by the service” and therefore avoiding this combination in the future).
