Design And Implement GDI Print Driver Auto-test System

In this paper, according to the GDI printer driver testing the status quo of the field, made a GDI print driver auto-test system. Through in-depth analysis of the GDI printer driver, the introduction of automated testing of theories and methods, presented in part based on windows GDI API-based test methods. And on this basis, analysis of all the GDI functions, abstract argument; while scripting language designed to facilitate automated testing. Creating conditions for Implement automated test systems. The major research work in this paper including:(1) For all windows GDI functions to do the analysis, classification, while abstract argument. For a number of GDI functions to do a thorough analysis and automated testing with GDI functions make the need for a specific classification and parameters of the abstract.(2) Designed to adapt to automated test scripts, and includes the implementation of the script interpreter. Script has the following functions: declare variable; achieve cycle jump function; implementation and (1) Summary of the GDI function seamlessly. Script interpreter to achieve with the following functions: interpretation of the script, while interpretation of edge execution.(3) Designed for the primary user of the graphical interface. Primary users are not familiar with the script in the case of the first through the graphical interface to do most of the test.Auto-test systems based on windows GDI has a certain theoretical significance and practical value. On the actual printing process, GDI-based applications are to call the GDI functions to achieve printing. So, through all the GDI function of the scope of testing of all parameters, it can ensure the quality of the printer driver, you can provide users with a good printing experience. You can test this type of printer driver to make the theory of reference. Meanwhile, the GDI function abstraction, classification of the input parameters, making the design and implementation of automated scripts is possible. The introduction of automated testing theory, reducing the test inputs, has practical application value...
