MockMotor is a stand-alone, on-premises SOAP and REST stateful mock server that supports enterprise-level testing, including load and performance testing. The product allows teams to effectively decouple from downstream web services and their schedules, shifting the timelines left and enabling the testing of corner cases that are hard to test against live back ends.
