它描述了当一个特定的测试套件(test suite)运行时,程序源代码被执行的程度。例如,一些更具体的覆盖率指标有: Statement Coverage:描述源代码中有哪些代码行被执行,各自被执行了多少次 Branch coverage:一般用于描述if语句/或其它条件语句的各分支的执行情况 Function coverage:顾名思义,描述源代码中有哪些函数被执行了...

1. 语句覆盖(StatementCoverage) 又称行覆盖(LineCoverage),段覆盖(SegmentCoverage),基本块覆盖(BasicBlockCoverage),这是最常用也是最常见的一种覆盖方式,就是度量被测代码中每个可执行语句是否被执行到了。这里说的是“可执行语句”,因此就不会包括像C++的头文件声明,代码注释,空行,等等。非常好理解,只统计能够...
1、编译选项:-fprofile-arcs -ftest-coverage 使用上述编译选项编译、链接应用程序。其中 gcov使用小节 Linux下可用gcov工具生成覆盖率统计信息,然后借助gcov的图形化工具lcov,可生成html格式的代码覆盖率报告,进一步提高覆盖率测试结果的可读性。 当构建一个程序时,gcov会监视一个程序... main.gcda 六、覆盖率分析...
这是因为无论循环的输入是什么，无条件循环总是会执行X次(想想总是从0开始，总是以常量值结束的for...

(at the lowest resolution), it works best with a programming style that places only one statement on each line. If you use complicated macros that expand to loops or to other control structures, the statistics are less helpful---they only report on the line where the macro call appears. ...
In software development code coverage is a mechanism used to know the degree to which a program is executed when a particular test suite executes on it. The facts regarding code coverage as a forecaster of software quality is contradictory and inconclusive. However, an estimation of the software...
