一、引言

1、java單元測(cè)試框架

junit
testNG
Spock

2、可以用來(lái)生成覆蓋率報(bào)告的插件

Jacoco
Cobertura

3、sonarqube上的單元測(cè)試覆蓋率

SonarQube 不會(huì)運(yùn)行測(cè)試或生成報(bào)告。要在分析中包含覆蓋結(jié)果，需要設(shè)置第三方覆蓋工具來(lái)生成報(bào)告并配置 SonarQube 以導(dǎo)入這些報(bào)告。

生成單元測(cè)試覆蓋率需要按照以下步驟操作：

SonarQube 使用導(dǎo)入的覆蓋率報(bào)告中的覆蓋行和可執(zhí)行行（或要覆蓋的行）來(lái)計(jì)算其覆蓋率指標(biāo)。 SonarQube 計(jì)算覆蓋率如下：

二、Jacoco
