如何管理运行时权限 android marshmallow espresso 测试 [英] How to manage Runtime permissions android marshmallow espresso tests

问题描述

我正在使用 espresso 进行测试，但有时我尝试从外部存储中获取图像，而对于棉花糖，我需要运行时权限，否则会发生异常崩溃并且测试将失败.

I'm using espresso for testing but sometimes I try to get an image form external storage and with marshmallow I need a Runtime permission otherwise there will be an Exception crash and the test will fail.

androidTestCompile 'com.android.support.test:runner:0.4'
androidTestCompile 'com.android.support.test:rules:0.4'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.1'
androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.2.1') {
    // this library uses the newest app compat v22 but the espresso contrib still v21.
    // you have to specifically exclude the older versions of the contrib library or
    // there will be some conflicts
    exclude group: 'com.android.support', module: 'appcompat'
    exclude group: 'com.android.support', module: 'support-v4'
    exclude module: 'recyclerview-v7'
}
androidTestCompile 'junit:junit:4.12'
androidTestCompile 'com.squareup.retrofit:retrofit-mock:1.9.0'
androidTestCompile 'com.squareup.assertj:assertj-android:1.1.0'
androidTestCompile 'com.squareup.spoon:spoon-client:1.2.0'

我怎样才能做到这一点?

how can I manage that right?

我应该为运行时权限编写测试还是有办法禁用它进行测试?

should I write test for Runtime permissions or there's a way to disable it for testing?

我应该像她在这里说的那样在测试运行之前授予权限吗?https://www.youtube.com/watch?list=PLWz5rJ2EKKc-lJo_RGGXL2Psr8vVCTWjM&v=C8lUdPVSzDk;v=C8lUdPVSzDk

should I give permissions before the tests run like she says here? https://www.youtube.com/watch?list=PLWz5rJ2EKKc-lJo_RGGXL2Psr8vVCTWjM&v=C8lUdPVSzDk

推荐答案

你可以创建一个Android gradle任务来授予权限:

You can create an Android gradle task to grant permission:

android.applicationVariants.all { variant ->
    def applicationId = variant.applicationId
    def adb = android.getAdbExe().toString()
    def variantName = variant.name.capitalize()
    def grantPermissionTask = tasks.create("grant${variantName}Permissions") << {
        "${adb} devices".execute().text.eachLine {
            if (it.endsWith("device")){
                def device = it.split()[0]
                println "Granting permissions on devices ${device}"
                "${adb} -s ${device} shell pm grant ${applicationId} android.permission.CAMERA".execute()
                "${adb} -s ${device} shell pm grant ${applicationId} android.permission.ACCESS_FINE_LOCATION".execute()
            }
        }
    }
}

这是运行任务的命令:<代码>gradle grantDebugPermissions
