A method and system of migratory hardware diagnostic testing is disclosed. In one embodiment, a method includes performing a diagnostic test of a hardware component of a first partition of a server using a first test module embedded in the first partition in response to a receipt of a test command, and storing context data associated with the diagnostic test of the hardware component in a memory associated with the hardware component, where the context data indicates a current state of the diagnostic test of the hardware component. Further, the method includes analyzing the context data upon a receipt of an instruction for a migration of the hardware component to a second partition of the server, and continuing the diagnostic test of the hardware component using a second test module embedded in the second partition based on the context data if the migration is performed.
