Visualizations for Learned Software Interfaces

Embodiments learn and visualize a software component and interface. Software code including a series of events can be received, where the series of events include calls to a software component and interface under test. Supplemental code can be injected into the received code. The software code with the injected supplemental code can be executed, where the executed supplemental code generates state data for the software component and interface. Based on the generated state data, a state diagram visualization can be generated that visualizes states and state transitions for the software component and interface under test given the series of events.
