As the quantity of the software testability measurement method is finite there is maybe no appropriate method existed for some measurement requests. To solve this problem a request-oriented method of software testability measurement is proposed. Firstly, all testability measurement requests from software, testing and users are identified. Secondly, every element matching the software and testing requests is derived from a testability measurement framework consisting of factors related with testability measurement of all kinds of software. Finally, a new measurement framework is constructed with the selected elements and results can be calculated based on the framework to fit the requests of users. Comparing with other methods the new method can measure the testability of all kinds of software. With the ability of measuring the testability of different software with the same process the new method can not only simplify the process of software testability measurement but also accelerate the application and development of software testability measurement.
