单元测试框架GTest的自动调用机制分析

Analysis of Auto-call Mechanism of Unit Testing Framework GTest

单元测试框架是测试驱动开发模式中的核心工具,当前的研究主要集中在单元测试框架的使用方法,对框架的实现原理研究较少。研究了谷歌公司的开源测试框架GTest的自动调用机制,首先概述了GTest框架的核心技术,然后以自带的Sample1为例,研究了测试用例注册、测试用例执行过程的信息调度,最后研究了GTest的测试执行情况监听机制。

The unit testing framework is the core tool in the test-driven development mode. The current researches focus on the usage of frameworks, but the principles of frameworks are less involved. This paper studies the GTest which is an auto-call mechanism of the open source test framework of the Google Corporation. Firstly, it summarizes core technologies of the GTest. Then, taking the Sample 1 as an example, it studies the information scheduling of the test case registration and the test case execution processes. Finally, it studies the monitoring mechanism of the test execution of the GTest.
