Gradle Jacoco is a plugin for the Gradle build system that provides code coverage analysis using the JaCoCo Java Code Coverage library. It generates reports that show how much of the code is covered by tests and helps identify areas that need more testing. The plugin can be configured to generate coverage reports for different parts of the code, such as unit tests, integration tests, or acceptance tests. It also allows users to set coverage thresholds and fail the build if the coverage falls below the specified threshold. Overall, the Gradle Jacoco plugin is a powerful tool for developers to ensure their code is thoroughly tested and maintainable.

Jacoco是一个用于确认Java应用单元测试覆盖率的工具,它可以帮助开发人员评估他们的测试用例是否足够覆盖代码。在使用Gradle构建工具时,可以通过添加Jacoco插件来集成Jacoco。
以下是使用Gradle和Jacoco的步骤:
1. 在build.gradle文件中添加Jacoco插件:
```groovy
apply plugin: 'jacoco'
```
2. 配置Jacoco的相关设置,例如报告生成格式和输出路径:
```groovy
jacoco {
toolVersion = "0.8.7"
reportsDir = file("$buildDir/reports/jacoco")
reports {
xml.enabled = true
html.enabled = true
}
}
```
3. 配置Jacoco的任务,例如测试任务和报告任务:
```groovy
test {
jacoco {
append = false
destinationFile = file("$buildDir/jacoco/test.exec")
}
}
jacocoTestReport {
dependsOn test
reports {
xml.enabled = true
html.enabled = true
}
}
```
4. 运行Gradle任务以生成Jacoco报告:
```shell
gradle jacocoTestReport
```
生成的Jacoco报告将包括代码覆盖率的详细信息,以HTML和XML格式呈现。
gradle 多模块 jacoco
Jacoco是一个覆盖率测试工具,Gradle是一个构建工具,两者结合可以实现多模块的Jacoco测试覆盖率。
首先,在根目录的build.gradle文件中添加Jacoco插件:
```groovy
plugins {
id 'jacoco'
}
```
然后,在每个子模块的build.gradle文件中,配置Jacoco插件和测试任务:
```groovy
plugins {
id 'java'
id 'jacoco'
}
jacoco {
toolVersion = "0.8.6"
}
test {
jacoco {
append = true
destinationFile = file("$buildDir/jacoco/jacoco.exec")
}
}
jacocoTestReport {
dependsOn test
reports {
xml.enabled = true
html.enabled = true
csv.enabled = false
jacocoModel {
xml.enabled false
csv.enabled = true
}
}
}
```
其中,jacocoTestReport任务会生成测试覆盖率报告,依赖于test任务,因此需要先运行test任务。
最后,在根目录的build.gradle文件中添加如下代码,配置所有子模块的Jacoco测试覆盖率报告:
```groovy
subprojects {
apply plugin: 'jacoco'
jacoco {
toolVersion = "0.8.6"
}
jacocoTestReport {
reports {
html.enabled = true
xml.enabled = true
}
}
}
```
这样就可以在根目录下运行如下命令,生成所有子模块的Jacoco测试覆盖率报告:
```
./gradlew clean build jacocoTestReport
```
