Android 多模块应用的测试覆盖率报告
Android test coverage report for multi module app
我们有一个多模块应用程序。我们有 3 个图书馆项目和 1 个启动项目。
module1（图书馆）
module2 (Libraray) 依赖于 module1
module3 (Libraray) 依赖于 module1
启动（没有任何源代码，它只是所有库的启动器）取决于模块 1 和模块 2。
在模块 1 中，我们使用外观模式访问模块 2 和模块 3 类。由于我们需要在 Launch 项目中编写所有测试用例，因为我们可以访问启动项目中的所有 类，这样我们就可以访问所有 类 并且测试用例不会因失败而失败到 NoClassDefException。
当我们在 Launch 项目中编写测试用例时，我们能够 运行 测试用例，我们得到 100% 的执行报告，并创建一个 index.html 文件，其中包含所有测试用例的详细信息，但是当我尝试生成覆盖率报告时，它没有显示覆盖率报告的任何数据。下面是我的 gradle 文件。

这是我们在顶部 build.gradle 中用于生成 HTML 覆盖率报告的内容：
def coverageSourceDirs = ['app/src/main/java', 'core/src/main/java', 'database/src/main/java']
def coverageExcludes = ['**/R.class',
'**/R$*.class',

def coverageClassDirectories = [fileTree(dir: 'app/build/intermediates/classes/debug', excludes: coverageExcludes),
fileTree(dir: 'core/build/intermediates/classes/debug', excludes: coverageExcludes),
fileTree(dir: 'database/build/intermediates/classes/debug', excludes: coverageExcludes)]
task jacocoRootReport(type: JacocoReport) {

additionalSourceDirs = files(coverageSourceDirs)

xml.enabled = false
csv.enabled = false
}
onlyIf = {
true
}
doFirst {

it.exists()
})
}
}
并且在每个子模块中：
android {
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
testCoverageEnabled = true
}
}
}
def coverageSourceDirs = ['src/main/java']
task jacocoTestReport(type: JacocoReport, dependsOn: "testJenkinsUnitTest") {
group = "Reporting"
description = "Generate Jacoco coverage reports"
classDirectories = fileTree(dir: 'build/intermediates/classes/debug',
excludes: ['**/R.class',
'**/R$*.class',
'**/*$$ViewBinder*.*',
'**/inject/*',
'**/*$InjectAdapter.*',

'**/Manifest*.*',
'**/Dagger*.*',
'**/*_Provide*Factory.*',
'**/*_Member*Injector.*',

additionalSourceDirs = files(coverageSourceDirs)
sourceDirectories = files(coverageSourceDirs)
executionData = files('build/jacoco/testDebugUnitTest.exec')
doFirst {
new File("$buildDir/intermediates/classes/").eachFileRecurse { file ->
if (file.name.contains('$$')) {
file.renameTo(file.path.replace('$$', '$'))
}
}
}
reports {
xml.enabled = false
html.enabled = true
}
}
请注意，如果您使用 Jenkins 插件或 Sonar 进行覆盖率分析，则不需要它。
P.S。如果您有任何问题，请手动检查所有路径，我可能会输入错误的内容。设置它真的很痛苦
我有 3 个名为 gcm_demo 的模块，googleservices 和 networkcommunication
所以在每个模块的 build.gradle 下
写
apply plugin: 'jacoco'
task jacocoTestReport(type: JacocoReport, dependsOn: ['testDebugUnitTest', 'createDebugCoverageReport']) {
reports {
xml.enabled = true
html.enabled = true
}
def fileFilter = ['**/R.class', '**/R$*.class', '**/BuildConfig.*', '**/Manifest*.*', '**/*Test*.*', 'android/**/*.*']
def debugTree = fileTree(dir: "${buildDir}/intermediates/classes/debug", excludes: fileFilter)
def mainSrc = "${project.projectDir}/src/main/java"
sourceDirectories = files([mainSrc])
classDirectories = files([debugTree])
executionData = fileTree(dir: "$buildDir", includes: [
"jacoco/testDebugUnitTest.exec", "outputs/code-coverage/connected/*coverage.ec"
])
}
现在在项目 build.gradle 中编写以下脚本
apply plugin: 'jacoco'
task jacocoRootReport(type: JacocoReport, dependsOn: ['gcm_demo:jacocoTestReport', 'googleservice:jacocoTestReport', 'networkcommunication:jacocoTestReport']) {
reports {
xml.enabled = true
html.enabled = true
}
sourceDirectories = files([tasks.getByPath("gcm_demo:jacocoTestReport").sourceDirectories,
tasks.getByPath("googleservice:jacocoTestReport").sourceDirectories,
tasks.getByPath("networkcommunication:jacocoTestReport").sourceDirectories])
classDirectories = files([tasks.getByPath("gcm_demo:jacocoTestReport").classDirectories,
tasks.getByPath("googleservice:jacocoTestReport").classDirectories,
tasks.getByPath("networkcommunication:jacocoTestReport").classDirectories])
executionData = files([tasks.getByPath("gcm_demo:jacocoTestReport").executionData,
tasks.getByPath("googleservice:jacocoTestReport").executionData,
tasks.getByPath("networkcommunication:jacocoTestReport").executionData])
}
执行用
gradlew clean jRR (short abbreviation)
构建成功后输出文件夹为
{project location}\build\reports\jacoco\jacocoRootReport\html\index.html
它提供 UI 和 unitTest
的完整项目覆盖
除了使用 getByPath 之外，您还可以使用 build.gradle 本身的变量来访问不同的模块，例如 $buildDir 将带您到当前模块 build 文件夹。
其次，$project.projectDir.parent 将转到父项目。示例 $project.projectDir.parent/<sub-project-name>/outputs/code-coverage/connected/coverage.ec
您可以使用您的子项目名称：gcm_demo, googleservices or networkcommunication
作为 $project.projectDir.parent/gcm_demo/outputs/code-coverage/connected/coverage.ec
注意：确保您使用正确的文件 coverage.ec 或 coverage.exec 检查为您生成的内容
要打印所有路径，您可以在build.gradle中使用以下任务：
运行 gradle paths 定义为
task paths {
println "Printing the current module build: $buildDir"
println "Printing the module directory: $project.projectDir"
println "Printing the parent module: $project.projectDir.parent"
}
这将帮助您在多模块 android 项目中使用目录和文件夹。我的问题是无法从子模块 build.gradle
访问正确的文件夹和文件目录
