cc++单元测试问答（Cc++ unit test questions and answers） C/C++ unit test quiz (Abstract) Why should the unit test? The quality of local code to ensure the unit test The overall structure of the unit test code improvement project Unit testing test, reduce maintenance costs of upgrading The unit test of the development process to adapt to the frequent changes in demand The ability of unit testing helps programmers Who is the test? Department of development or testing department? Should the Development Department of the unit test! Unit test problems by testing department: high cost, shortage of manpower, delay the preparation test department on other test. The problem of unit test development department: programmers dont worry about the impact of the development progress, the habit of doing unit testing, test their code to ensure the test results. No matter which department do unit testing, have to face some problems, but the development of the problems faced by the Department can use the tools to solve, and by the test department for unit testing, or can not be truly implemented, or costly. By the test department unit test why expensive? Repeated understanding program Repeated communication requires a lot of time cost Not to play the constraint mechanism to unit test code structure Ready to work on other test delay test department Even if the test department staffed, only from the benefits to consider, it should not be the testing department for unit testing. If the test is not sufficient (HR department for unit testing personnel must possess ability, by encoding) to test department unit testing, the result is often no results. Unit testing can ensure the test results by the engineering department? Programmers to test their code, they only consider normal, it will certainly impact test results. But if the unit test tools are used to white box coverage statistics, can check the test results. Of course, only this is not enough, because the white box coverage has the characteris
