Function external decoupling and testing method

TL;DR: In this article, a function external decoupling and testing method is described, which comprises the following steps that: function classification: analyzing a tested source file, and classifying a function to be tested; function coupling: according to the function classification, carrying out coupling, and carrying out a next step if the test is a non-coupling function, if the function iscoupled, setting an external coupling function, and then carrying out the next step; and function testing: utilizing a testing unit tool to generate a test use cage, and carry out a test

Abstract: The invention discloses a function external decoupling and testing method, which comprises the following steps that: function classification: analyzing a tested source file, and classifying a functionto be tested; function coupling: according to the function classification, carrying out coupling, carrying out a next step if the function to be tested is a non-coupling function, if the function iscoupled, setting an external coupling function, and carrying out a next step; and function testing: utilizing a testing unit tool to generate a test use cage, and carrying out a test according to a function classification and function coupling situation. By use of the method, after the function is decoupled, an external variable or public data is indirectly initialized, initialization does not need to be manually added, and unit testing efficiency is greatly improved.
