在执行代码覆盖率指标方面需要帮助。我的解决方案基于this博客文章。 为了解决这个问题，我已经介绍了以下帖子。
（真的很尴尬-看起来我仍然缺少一些东西:(）
我能够获得代码覆盖率，但无法强制执行最低阈值。
这是我的Jacoco.gradle的样子-
apply plugin: 'jacoco'
jacoco {
toolVersion = "0.8.2"
}
project.afterEvaluate {
// Grab all build types and product flavors
def buildTypes = android.buildTypes.collect { type ->
type.name
}
def productFlavors = android.productFlavors.collect { flavor ->
flavor.name
}
// When no product flavors defined, use empty
if (!productFlavors) productFlavors.add('')
productFlavors.each { productFlavorName ->
buildTypes.each { buildTypeName ->
def sourceName, sourcePath
if (!productFlavorName) {
sourceName = sourcePath = "${buildTypeName}"
} else {
sourceName = "${productFlavorName}${buildTypeName.capitalize()}"
sourcePath = "${productFlavorName}/${buildTypeName}"
}
def testTaskName = "test${sourceName.capitalize()}UnitTest"
// Create coverage task of form 'testFlavorTypeCoverage' depending on 'testFlavorTypeUnitTest'
task "${testTaskName}Coverage" (type:JacocoReport, dependsOn: "$testTaskName") {
reports {
xml.enabled = true
html.enabled = true
}
group = "Reporting"
description = "Generate Jacoco coverage reports on the ${sourceName.capitalize()} build."
classDirectories = fileTree(
dir: "${project.buildDir}/intermediates/javac/${buildTypeName}",
excludes: [
'**/R.class',
'**/R$*.class',
'**/*$ViewInjector*.*',
'**/*$ViewBinder*.*',
'**/BuildConfig.*',
'**/Manifest*.*'
]
)
def coverageSourceDirs = [
"src/main/java",
"src/$productFlavorName/java",
"src/$buildTypeName/java"
]
additionalSourceDirs = files(coverageSourceDirs)
sourceDirectories = files(coverageSourceDirs)
executionData = files("${project.buildDir}/jacoco/${testTaskName}.exec")
}
}
}
}
我已经在应用模块的build.gradle中包含了以上脚本。
apply plugin: 'com.android.application'
apply from: '../jacoco.gradle'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.example.jacocodemo"
minSdkVersion 27
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
debug {
testCoverageEnabled = true
}
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
到目前为止，我已经尝试了许多不同的方法。看起来Jacoco文档偏向于简单的Java项目，因为在Android中使用时，代码片段几乎总是需要更改，但即使这样也没有运气。
这是我尝试解决的问题- （只需在其中输入Jacoco.gradle，因为其中包含主要代码）
apply plugin: 'jacoco'
jacoco {
toolVersion = "0.8.2"
}
// ****** THIS IS MY ATTEMPT AT IT [START] ******
task jacocoTestCoverageVerification(type: JacocoCoverageVerification) {
violationRules {
rule {
enabled = true
limit {
minimum = 0.9
}
}
}
}
check.dependsOn jacocoTestCoverageVerification
// ****** THIS IS MY ATTEMPT AT IT [END] ******
project.afterEvaluate {
// Grab all build types and product flavors
def buildTypes = android.buildTypes.collect { type ->
type.name
}
def productFlavors = android.productFlavors.collect { flavor ->
flavor.name
}
// When no product flavors defined, use empty
if (!productFlavors) productFlavors.add('')
productFlavors.each { productFlavorName ->
buildTypes.each { buildTypeName ->
def sourceName, sourcePath
if (!productFlavorName) {
sourceName = sourcePath = "${buildTypeName}"
} else {
sourceName = "${productFlavorName}${buildTypeName.capitalize()}"
sourcePath = "${productFlavorName}/${buildTypeName}"
}
def testTaskName = "test${sourceName.capitalize()}UnitTest"
// Create coverage task of form 'testFlavorTypeCoverage' depending on 'testFlavorTypeUnitTest'
task "${testTaskName}Coverage" (type:JacocoReport, dependsOn: "$testTaskName") {
reports {
xml.enabled = true
html.enabled = true
}
group = "Reporting"
description = "Generate Jacoco coverage reports on the ${sourceName.capitalize()} build."
classDirectories = fileTree(
dir: "${project.buildDir}/intermediates/javac/${buildTypeName}",
excludes: [
'**/R.class',
'**/R$*.class',
'**/*$ViewInjector*.*',
'**/*$ViewBinder*.*',
'**/BuildConfig.*',
'**/Manifest*.*'
]
)
def coverageSourceDirs = [
"src/main/java",
"src/$productFlavorName/java",
"src/$buildTypeName/java"
]
additionalSourceDirs = files(coverageSourceDirs)
sourceDirectories = files(coverageSourceDirs)
executionData = files("${project.buildDir}/jacoco/${testTaskName}.exec")
}
}
}
}
，然后我尝试如下调用它： gradle清理构建testDebugUnitTestCoverage jacocoTestCoverageVerification。 非常感谢您对此提供任何帮助。
