Abstract: Methods and systems for implementing proxy layers an a proxy layer management framework for performing integration testing of test components in a target test environment. Proxy layers are established between components that interact in a system and provide an interface based on a communication protocol, such as HTTP or RPC. Proxy layers axe configured, via a proxy layer manager to reroute communication, based on the communication protocol, to and from test components to simulate integration testing of the components in the target environment. Proxy layers may also apply rules that reroute traffic based on certain conditions for more effective, safer, and specific testing. Also, the routed communications may be traced and logged for testing and debugging.
