A solution for managing software dependencies during software testing and debugging includes a capture module configured to capture a software call stack of a software execution environment, each software call of the software call stack including a call signature and a call result. The solution defines a set of proxied software calls within the software call stack suitable for simulating conversation responses to runtime software calls by a target application. Once a set of proxied software calls is defined, a playback module recognizes runtime software calls by the target application that are within the set of proxied software calls and responds to the recognized runtime software call with a captured call result corresponding to the recognized software call.
