Android代码覆盖率初探—问题已解决!
6月份到时候就要搞Android代码覆盖率,但是当时客户端即将改版,所以就耽搁了。在Android大哥的帮助下,终于完成了初步的代码覆盖率统计。
在github上找到了封装好的jacocoTestHelper:https://github.com/Jay-Goo/JacocoTestHelper,在splash页调用JacocoHelper.init(),在退出app时调用JacocoHelper.generateEcFile(true)
gradle配置:
apply plugin: 'com.android.application'
apply plugin: 'jacoco'
def coverageSourceDirs = [
'../app/src/main/java'
]
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.test.app"
minSdkVersion 18
targetSdkVersion 25
versionCode 37
versionName "1.8.20.5"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
debug {
testCoverageEnabled = true
}
release {
testCoverageEnabled = true
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
lintOptions{
checkReleaseBuilds false
abortOnError false
}
}
task jacocoTestReport(type: JacocoReport) {
group = "Reporting"
description = "Generate Jacoco coverage reports after running tests."
reports {
xml.enabled = true
html.enabled = true
}
classDirectories = fileTree(
dir: './build/intermediates/classes/debug',
excludes: ['**/R*.class',
'**/*$InjectAdapter.class',
'**/*$ModuleAdapter.class',
'**/*$ViewInjector*.class'
])
sourceDirectories = files(coverageSourceDirs)
executionData = files("$buildDir/outputs/code-coverage/connected/coverage.ec")
doFirst {
new File("$buildDir/intermediates/classes/").eachFileRecurse { file ->
if (file.name.contains('$$')) {
file.renameTo(file.path.replace('$$', '$'))
}
}
}
}
dependencies {
compile 'com.github.Jay-Goo:JacocoTestHelper:v0.0.2'
}
现在仍存在问题:
手动执行时,执行结束按home退出,再重新打开app时,覆盖率统计可以叠加。如果用appium执行测试,每次open application时会重启app(我猜),重新调用JacocoHelper.init(),这样每执行一条都会生成一个coverage.ec文件,如何用多个ec文件生成覆盖率报告是未来要解决的问题,或者说,是否存在一种方法让appium open application的时候不进行杀掉重启。啊,任重道远啊。
另:最近发现用python直接写case并没有比用RF麻烦,而且执行速度感觉比RF快一点。RF的优点在于可以直观管理用例,android方面的关键字自己还是需要封装一些,现有的AppiumLibrary不能满足需求。
另2:此时特想搞个mbp,但是就以现在买买买的节奏,啥时候能攒下来钱哇(望天)

问题得以解决哈哈哈哈哈哈哈,稍晚更新解决方案,开心哈哈哈哈哈哈哈哈哈

更新:
appium每执行完一个case,点击两次回退退出app,将/mnt/sdcard/coverage.ec导出并重命名到指定路径(本文为$buildDir/outputs/code-coverage/connected/)
在gradle中增加:
task removeOldMergeEc(type: Delete) {
delete "$buildDir/outputs/code-coverage/connected/mergedcoverage.ec"
}
task mergeReport(type:JacocoMerge,dependsOn:removeOldMergeEc){
group = "Reporting"
description = "merge jacoco report."
destinationFile= file("$buildDir/outputs/code-coverage/connected/mergedcoverage.ec")
//"$buildDir/outputs/code-coverage/connected/"为存放.ec文件的路径
FileTree tree = fileTree("$buildDir/outputs/code-coverage/connected/") {
include '**/*.ec'
}
executionData = tree
}
并将上文task jacocoTestReport(type: JacocoReport)中以下代码进行修改:
executionData = files("$buildDir/outputs/code-coverage/connected/coverage.ec)
改为:
executionData = files("$buildDir/outputs/code-coverage/connected/mergedcoverage.ec")
所有case执行结束后,执行
gradlew mergeReport -Pec_dir="F:\Mox\Mox\mox-portal\build\outputs\code-coverage\connected"
确认"$buildDir/outputs/code-coverage/connected/路径下已生成mergedcoverage.ec后
gradlew jacocoTestReport
然后就可以开心的查看报告啦~
