如何使用某些排除的类和 jacoco 插件验证最低覆盖率



我需要检查新 jacoco 任务的最小覆盖范围

雅科测试覆盖率验证

此任务在 3.4.1 gradle 版本中可用,jacoco 插件>= 0.6.3

我可以运行另一个任务来生成具有分支覆盖率的 html 报告,但现在我想使用该数字使构建失败。

这是我的代码

buildscript {
    ext {
        ....
    }
    repositories {
        mavenCentral()
        maven {
            ....
        }
    }
    dependencies {
        .....
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'jacoco'
jar {
    baseName = "coverage-test"
}

dependencies {
    // my dependencies
}

eclipse {
    classpath {
         containers.remove('org.eclipse.jdt.launching.JRE_CONTAINER')
         containers 'org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8'
    }
}
wrapper {
    gradleVersion = '3.4.1'
}
jacoco {
    toolVersion = '0.7.9'
}
jacocoTestReport {
    reports {
        xml.enabled false
        csv.enabled false
    }    
    group = "Reporting"
    description = "Generate Jacoco coverage reports after running tests."
    additionalSourceDirs = files(sourceSets.main.allJava.srcDirs)
    afterEvaluate {
        classDirectories = files(classDirectories.files.collect {
            fileTree(
                dir: it,
                excludes: 
                [
                        'com/jacoco/dto/**',
                        'com/jacoco/configs/**', 
                        //and others
                ])
        })
    }
}
jacocoTestCoverageVerification {
    //I tried this and it didn't work
  //   classDirectories = files(classDirectories.files.collect {
  //   fileTree(
  //    dir: it,
        // excludes: 
        // [
        //      'com/jacoco/dto/**',
        //      'com/jacoco/configs/**', 
        //      //and others
        // ])
  //   })
    violationRules {
        rule {
            //Also tried this and it didn't work
           // excludes = ['com/jacoco/dto/**', ...]
            limit {
                counter = 'BRANCH'
                minimum = 0.8
            }
        }
    }
}
check.dependsOn jacocoTestCoverageVerification

使用类目录,我收到以下错误无法在空对象上获取属性"文件"。使用第二个选项(仅排除(,构建运行顺利,但不排除任何类。

就我而言,我确实想使用 BUNDLE 范围为整体设置阈值,同时排除某些文件

最终对我有用的是添加classDirectories排除,如原始问题中所建议的那样,但在afterEvaluate内部是这样的:

afterEvaluate {
        classDirectories = files(classDirectories.files.collect {
            fileTree(dir: it, exclude:  [
                    'com/example/my/package/*',
                    'com/example/service/MyApplication.class',
                    'com/google/protobuf/*'
            ])
        })
    }

作为参考,完整的build.gradle如下所示:

apply plugin: "jacoco”
jacocoTestCoverageVerification {
    afterEvaluate {
        getClassDirectories().setFrom(classDirectories.files.collect {
            fileTree(dir: it, exclude:  [
                    'com/example/my/package/*',
                    'com/example/service/MyApplication.class',
                    'com/google/protobuf/*'
            ])
        })
    }
    violationRules {
        rule {
            limit {
                minimum = 0.79
            }
        }
    }
}

// to run coverage verification during the build (and fail when appropriate)
check.dependsOn jacocoTestCoverageVerification

您正在测量您正在排除的不同事物。默认的JaCoCo范围是"BUNDLE",我相信这意味着整个代码。我从来没有用过那个。我总是只测量"类"范围。看起来你也在尝试做同样的事情。

排除项相对于作用域中的元素。不确定它对"捆绑"意味着什么,但我几乎倾向于认为它要么全有,要么全无。排除也使用不同类型的通配符。尝试更改配置以使用元素"CLASS"(或"PACKAGE"(。

violationRules {
    rule {
        element = 'CLASS'
        excludes = ['com.jacoco.dto.*']
        limit {
            counter = 'BRANCH'
            minimum = 0.8
        }
    }
}
check.dependsOn jacocoTestCoverageVerification
