MultiDexApplication的使用导致Application类的Robolectric测试中断

Question

使用gradle def(https://plus.google.com/+IanLake/posts/JW9x4pcB1rj)在支持v4-r21上添加Multi dex支持

apply plugin: 'com.android.application'

android {
compileSdkVersion 19
buildToolsVersion "20.0.0"

defaultConfig {
    applicationId "info.osom.multidex"
    minSdkVersion 19
    targetSdkVersion 19
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

dexOptions {
    preDexLibraries = false
}

afterEvaluate {
    tasks.matching {
    it.name.startsWith('dex')
    }.each { dx ->
    if (dx.additionalParameters == null) {
        dx.additionalParameters = []
    }
    dx.additionalParameters += '--multi-dex'
    dx.additionalParameters += "--main-dex-list=$projectDir/multidex.keep".toString()
}

现在这适用于应用程序本身,我能够构建和部署,但是当我为我的Application类运行robolectric测试时,我从ZipUtils(在MultiDex.java中捕获)中失败了.其他测试运行正常.这是痕迹 -

Answer 1

添加multi-dex shadow作为依赖项:

testCompile "org.robolectric:shadows-multidex:3.0"

这将模拟MultiDex.install调用并且什么都不做,因为Robolectric中没有dex

Answer 2

这是一个已知错误，等待修复：https ://github.com/robolectric/robolectric/issues/1328
