How to Use Espresso v2.0 with Testdroid Cloud Devices

1.Modify build.gradle

• Add 'testInstrumentationRunner"android.support.test.runner.AndroidJUnitRunner"' in defaultConfig
• Add packagingOptions to avoid Liscens conflict
• Add dependencies about Espresso

e.g : build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.philips.pins.espresso.demo"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        exclude 'LICENSE.txt'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    // Espresso 相关的引用
    androidTestCompile('com.android.support.test:runner:0.3') {
        exclude module: 'support-annotations'
    }
    androidTestCompile('com.android.support.test:rules:0.3') {
        exclude module: 'support-annotations'
    }
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2') {
        exclude module: 'support-annotations'
    }
    androidTestCompile('com.android.support.test.espresso:espresso-intents:2.2') {
        exclude module: 'support-annotations'
    }
}

2.Create Test Class

1. Create a @Rule to express test which activity
2. Create Annotation @Test method to test

p.s: Espresso is based on Juit, so it's okay to override setUp() and tearDown()

e.g: MainActivityTest.java

@RunWith(AndroidJUnit4.class)
@LargeTest
public class MainActivityTest {
    @Rule
    public ActivityTestRule<MainActivity> mActivityRule = new ActivityTestRule(MainActivity.class);

    @Before
    public void setUp() throws Exception {
        Intent intent = new Intent();
        mActivityRule.launchActivity(intent);
    }

    @After
    public void tearDown() throws Exception {


    }

    @Test
    public void testTextViewDisplay() {
        onView(withText("Hello World!")).check(ViewAssertions.matches(isDisplayed()));
    }

}

Besides, it seems necessary to lock the screen when we use Espresso to test.

2.Spoon （一款辅助测试并生成测试报告的插件）

spoon的强大之处：

• 多机并行执行：同时在多台手机中执行自动化测试用例，以便在不同版本的Android操作系统中进行回归测试、兼容性测试
• 出错重试及出错截图：当用例执行未通过时，可以自动进行重跑并截图记录，以便减少因偶然因素导致用例执行未通过的情况
• 实时日志记录：对于测试执行过程应该能记录运行时的日志，以便详细发解测试执行情况
• 跨应用的能力：能够测试包含跨应用的诸多情况
• 生成Junit形式测试报告：生成详细的Junit形式的测试报告，可方便查看测试用例执行结果
• 代码覆盖率报告：生成代码覆盖率报告，以便进一步指导测试策略
• 持续快速反馈的能力：对于测试运行情况，应该要能够快速反馈
• 易于访问的报告：能够很方便地访问到测试报告详情

How to use spoon

1. Download the latest runner JAR(This project contanins spoon-runner-1.3.2-jar-with-dependencies.jar)
2. Add the latest client JAR to your dependencies or download it

androidTestCompile 'com.squareup.spoon:spoon-client:1.3.2'

3. Run Spoon as a standalone tool with your application and instrumentation APKs.

cmd e.g:

java -jar spoon-runner-1.3.2-jar-with-dependencies.jar 
--apk D:\Espresso\app\build\outputs\apk\app-debug-unaligned.apk 
--test-apk D:\Espresso\app\build\outputs\apk\app-debug-androidTest-unaligned.apk 
--sdk C:\Users\310231492\AppData\Local\Android\sdk

4. Get test report in folder spoon-output

p.s: use Spoon.screenShot() to take screenshots, but do not forget to add the WRITE_EXTERNAL_STORAGE permission

Spoon.screenshot(activity, "initial_state");
/* Normal test code... */
Spoon.screenshot(activity, "after_login");
