android 连接测试的定制测试报告（浓缩咖啡）

Question

We have a JUnit test Rule for espresso tests that records test results in a json file. After test execution the json file is pulled from the device/emulator back to the pc, using adb shell pull command.

above solution works only if we run the test using adb but not with Gradle. Gradle uninstalls the apk after running the connected tests, therefore the json file also gets removed from the device.

my question: Is there a way to copy the file before it gets deleted by Gradle?
I was wondering how other report generators tackle this issue?

Answer 1

Pulling most of this idea from here , but the tl;dr is that you can set up a gradle task to pull the file off of the device.

Real rough idea would be:

def pullJsonFromEmulator = task('Pull Json From Emulator', type: Exec) {
    executable "${android.getAdbExe().toString()}"
    args 'pull', 'pathToJson', 'destinationPath'
}

tasks.withType(Test) { task -> 
    task.finalizedBy {
        pullJsonFromEmulator
    }
}

The thought process is that you define your custom task to run that will pull the Json off of the emulator and store it somewhere. You can then use gradle's finalizedBy functionality to apply this task after all "test" tasks. You can obviously make it more granular, say only tasks with a certain name...

tasks.withType(Test) { task -> 
    if (task.name == "jsonTestTask") {
        task.finalizedBy {
            pullJsonFromEmulator
        }
    }
}
