The invention discloses a method and device for automatically testing full-process scene of an interface, and belongs to the technical field of artificial intelligence. The method comprises the steps of: configuring an interface document, a test case library and a business parameter document; obtaining a preorder interface access sequence list of a to-be-tested interface from the interface document, obtaining test cases corresponding to preorder interfaces from the test case library, obtaining parameters required by the preorder interfaces from the test cases, the interface document and the business parameter document, and writing the parameters into a reporting message, naming parameters which need to be acquired from messages returned from other interfaces, and writing parameter names into the reporting message; calling the preorder interfaces in sequence, completing parameter acquisition of the preorder interfaces, and storing the parameters in a parameter library according to parameter names; and acquiring the parameters from the test cases, the interface document, the business parameter document and the parameter library, writing the parameters into the reporting message of the to-be-tested interface, calling the to-be-tested interface, and completing the automatic interface test. According to the method and device of the invention, full-process interface scenarized automatic testing can be realized.
