Abstract: Techniques are provided for recording service invocation traffic in a format that is suitable for subsequent replay, perhaps in a different environment. In one technique, a computing device records invocation traffic. The computing device receives a first request that is directed to a first service. In response to receiving the first request, one or more computers store an identifier of the first request into a second request. After storing the identifier into the second request, the computing device causes the second request to be sent to a second service. After causing the second request to be sent to the second service, the computing device receives, from the second service, a response that contains the identifier of the first request. The one or more computers store, in a single record, the first request, the second request, and the response.

Abstract: Techniques are provided for mocking downstream services while regression testing a service. In one technique a version of a service processes a request, during which one or more computers intercept downstream service calls made by the version of the service. For each downstream service call of the downstream calls, a computer provides, to the version of the service, a response of the downstream service call, which was previously recorded while processing the request in a production environment. Processing, by the version of the service, the request involves processing the request based on the response of at least one of the downstream service calls.
