Object-driving software testability measurement

To reduce the difficulty and cost of software testability measurement, an object-driving method was proposed to measure the testability of various programs by a unified manner. It is based on a software testability metrics framework that consists of the testability metric, testable characteristics metrics, testability factors metrics and their relations. First, the measurement object was analyzed to determine the object type, the software type and test conditions. Then suited elements were chose from the metrics framework according to the software type and test conditions to construct a special software testability metrics framework. Finally advantage of the elements in the special metrics framework was taken to calculate the testability factors, testable characteristics or testability according to the object type. The application indicates this method can get the quantitative value of software testability and help the software testing by predicting the test resources.
