Uiautomator 2.0之UiDevice新增API學習小記

1. InstrumentationRegistry類

1.1. 類說明：

一個暴露的注冊實例，持有instrumentation運行的進程和參數，還提供了一種簡便的方法調用instrumentation, application context和instrumentation參數。

1.2 相關API

返回類型	API
static Bundle	getArguments(): 返回一個instrumentation參數副本
static Context	getContext():  返回instrumentation對應包的Context
static Instrumentation	getInstrumentation(): 返回當前運行的instrumentation
static Context	getTargetContext(): 返回一個目標應用程序的Context
static void	registerInstance(Instrumentation instrumentation, Bundle arguments): 記錄或暴露當前instrumentation運行和instrumentation參數包的副本，存儲在注冊中心

 1.3.1 測試代碼

import android.app.Instrumentation;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.support.test.InstrumentationRegistry;
import android.support.test.runner.AndroidJUnit4;
import android.support.test.uiautomator.UiDevice;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;

import java.io.IOException;

/**

@RunWith(AndroidJUnit4.class)
public class TestClass01 {
    public UiDevice mDevice;
    public Instrumentation instrumentation;

    @Before
    public void setUp(){
        instrumentation = InstrumentationRegistry.getInstrumentation();
        mDevice = UiDevice.getInstance(instrumentation);
    }

    @Test
    public void testCase01() throws IOException {
        //獲取運行時的參數
        Bundle args = InstrumentationRegistry.getArguments();
        //輸出到運行報告中
        instrumentation.sendStatus(100, args);

        //獲取測試包的Context
        Context testContext = InstrumentationRegistry.getContext();
        //獲取被測應用的Context
        Context testedContext = InstrumentationRegistry.getTargetContext();

        //通過Context來啟動一個Activity,e.g.瀏覽器
        String url = "https://www.baidu.com";
        Intent i1 = new Intent(Intent.ACTION_VIEW);
        i1.setData(Uri.parse(url));
        i1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        testContext.startActivity(i1);
        
        //通過目標Context來啟動撥號功能
        Intent i2 = new Intent(Intent.ACTION_CALL,Uri.parse("tel:" + 10086));
        i2.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        testedContext.startActivity(i2);
        
        Bundle inputBundle = new Bundle();
        inputBundle.putString("key", "value");
        //注入一個Bundle
        InstrumentationRegistry.registerInstance(instrumentation, inputBundle);
        //獲取運行參數
        Bundle outBundle = InstrumentationRegistry.getArguments();
        //輸出到結果報告中
        instrumentation.sendStatus(110,outBundle);


    }

}

 1.3.2 運行結果

2. UiDevice新增API

2.1 API 介紹

返回類型	API
void	dumpWindowHierarchy(OutPutStream out): 獲取當前頁面層級到輸出流
String	executeShellCommand(String cmd): 執行一個shell命令。備注：此方法只支持api21以上，手機需要5.0系統以上
UiObject2	findObject(BySelector selector): 返回第一個匹配條件的對象
UiObject	findObject(UiSelector selector): 返回一個匹配條件的代表視圖的UiObject對象
List<UiObject2>	findObjects(BySelector selector): 返回所有匹配條件的對象
<R> R	wait(SearchCondition<R> condition, long timeout): 等待的條件得到滿足
