A system and method for inspecting a testing state includes determining one or more entities to be manipulated during execution of a test of the system, generating an instance of each of the entities using a plurality of entity templates and a plurality of value generators, and executing the test using the generated instances. At least one of the generated instances includes a first value generated randomly. The test is being executed by one or more processors of the system. In some examples, generating an instance of a first one of the entities includes identifying a first one of the entity templates corresponding to a type of the first entity, determining one or more attributes for the first entity based on the first entity template, and generating an instance of each of the attributes using the entity templates and the value generators.
