gradle 如何添加测试覆盖率的配置要求

团队成员经常忘记写单元测试，那如何强制让写测试呢？

通过在 gradle 中添加相关的配置：

1. 在build.gradle中添加相关的配置

plugins中需要引入jacoco的依赖:

plugins {
	id 'java'
	id 'org.springframework.boot' version '3.3.2'
	id 'io.spring.dependency-management' version '1.1.6'
	id 'jacoco'
}

添加一个生成jacoco测试报告的任务:

jacocoTestReport {
	dependsOn test
	reports {
		xml.required = false
		csv.required = false
		html.outputLocation.set(layout.buildDirectory.dir("reports/jacoco"))
	}
	afterEvaluate {
		classDirectories.setFrom(files(classDirectories.files.collect {
			fileTree(dir: it, exclude: ['**/dto', '**/entity', '**/domain'])
		}))
	}
}

• 生成的测试报告路径: build/reports/jacoco/index.html
• 可以忽略某些文件，比如 entity 等

添加一个测试覆盖率检查的任务:

jacocoTestCoverageVerification {
	dependsOn test
	afterEvaluate {
		classDirectories.setFrom(files(classDirectories.files.collect {
			fileTree(dir: it, exclude: ['**/dto', '**/entity', '**/domain'])
		}))
	}
	violationRules {
		rule {
			limit {
				counter = 'LINE'
				value = 'COVEREDRATIO'
				minimum = 0.7
			}
		}
		rule {
			limit {
				counter = 'BRANCH'
				value = 'COVEREDRATIO'
				minimum = 0.8
			}
		}
	}
}

我这里lineCoverage 需要达到 70%, 分支覆盖率需要达到 80%

2. git hooks配置

3. CI/CD 中的配置
