coverage requires two points of data, one for which functions are executed, and one for the total number of functions in the file.
The total number of functions in the file, since we cannot execute all the functions again, this part can only be implemented by code static scanning. If you are in C + + or Java, you may need lexical analysis tools, but in the most

C/C ++ has very few statistical tools for code coverage. Compared with Java, there are very few open-source and free tools. It is very rare to use and open-source tools. Finally, we chose gcov-based lcov as the coverage rate statistics Tool for nginx testing. The reason for select
Testing for software, is to ensure the quality of an important process, and testing is divided into many kinds, unit testing, integration testing, system testing, stress testing, and so on, different test granularity and test objectives are different, such as unit testing focus on each line of code, integration testing is concerned about whether multiple modules can work together properly.When we measure the quality of the

Introduction: The Code coverage tool is an important tool used during software testing because it provides an idea of how the program is covered by the test case. This article shows you how to generate test
Code coverage is an important indicator that reflects the coverage of test cases to tested software. It is also an important indicator to measure the testing progress. It is also an important indicator for Testing. Testing is often not as exciting as development. One of the important reasons is that testing is difficult to quantify,

Introduction
CodeOverwriting is a method used to measure the level of executed software tests. The process of collecting covered metric data is simple: monitor your code and run the test on the version you are monitoring. In this way, you can generate relevant data to show which code has been executed, or, more importantly, which code has not been executed.
