The invention discloses a software testing method and device and belongs to the software testing field. The method includes the steps that data connection with an assigned server is established; a testing request is sent to the server, the testing request carries test case identification so that the server can acquire a target test case and at least one test instruction can be returned, the target test case is a test case corresponding to the test case identification, and the test instruction is obtained in the mode that the assigned server compiles the target test case; at least one test instruction sent by the assigned server is received; test operation corresponding to the at least one test instruction is executed. According to the software testing method and device, the assigned server provides storage and compiling of the test case, and therefore terminals can be matched with the assigned server through data connection between the terminals and the assigned server, testing, performed on software, of the terminals is completed, the server can be connected with the terminals at the same time, the terminals can test the software at the same time, and time consumption for testing of the terminals is greatly reduced.
