Example methods and systems for software bug reproduction. One example method may comprise obtaining log information associated with multiple transactions processed by a control-plane node to configure a set of data-plane nodes and transform an initial network state to a first network state; and configuring a replay environment that is initialized to the initial network state, and includes a mock control-plane node and a set of mock data-plane nodes. The method may also comprise, based on the log information, replaying the multiple transactions using the mock control-plane node to configure the set of mock data-plane nodes and transform the replay environment from the initial network state to a second network state. Based on a comparison between the first network state and the second network state, a determination may be made as to whether a software bug is successfully reproduced in the replay environment.
