A test information extraction device improves efficiency in testing applications by including: an obtainment unit that obtains, from a first source code group of an application that implements methods corresponding to requests of a plurality of types received via a network, first information used for generating the requests; and an extraction unit that specifies, from among the methods implemented in response to the requests, a method being a caller of a method included in a second source code group being a part of the first source code group and that further extracts, from the first information, second information used for generating one of the requests corresponding to the specified method.
