Various example embodiments are directed to computer-implemented systems and methods for generating tests. A computer system may execute an application host and a browser. Messages originating from the application host and messages directed to the application host may be routed through the browser. The browser may be programmed to capture a plurality of application-level messages, which may comprise a plurality of requests originating from an application host and a plurality of responses directed to the application host. The computer system may generate a test scenario based on the plurality of application-level messages.
