# 一、覆盖率简介 #

对某一段代码或者代码的某一种属性做测试，其测试达到的程度被称为是覆盖率  
代码覆盖率是检查单元测试对代码的测试程度。

# 二、代码覆盖率工具 #

市场上主要代码覆盖率工具：Emma、cobertura、jacoco、IntelliJ IDEA、Clover(商用)。

# 三、覆盖率测试步骤 #

## 1.基于单元测试，选择Edit Configurations ##

Element：目录的名称。  
Class：类的覆盖情况。  
Method：方法的覆盖情况。  
Line：行覆盖情况。  
Branch：分支覆盖情况。（此分支不是git的分支，是指if else的分支覆盖情况）  
左侧红色部分代码未覆盖  
左侧绿色表示代码已覆盖
