如何运行Travis-CI和Espresso测试

Question

我目前设置了Travis-CI，以便在我的Android设备的每个版本上运行Gradle ConnectedCheck任务并执行我所有的单元测试。我已经能够成功地设置它。我现在正尝试用Espresso进行一些功能测试，而我目前正忙于设置Travis，这样我的特浓咖啡测试就可以与Travis的模拟器交互了。我如何设置Travis，使其仿真器的工作方式与我在本地工作站上使用的仿真器完全相同？

这是我用来构建模拟器的.travis.yml的一部分。

language: android 
jdk: oraclejdk7 
env: 
    matrix: 
    - ANDROID_TARGET=android-19 ANDROID_ABI=armeabi-v7a 

android: 
    components: 
    - build-tools-20.0.0 
    - build-tools-19.1.0 

before_script: 
    # Create and start emulator 
    - echo no | android create avd --force -n test -t $ANDROID_TARGET --abi $ANDROID_ABI 
    - emulator -avd test -no-skin -no-audio -no-window & 
    - android-wait-for-emulator 
    - adb shell input keyevent 82 & 

Answer 1

更新：

VM映像已经包括固定Android的等待换模拟器默认脚本和Android SDK工具版本24.0.0和咖啡2.0正式发布，并转移到Android的测试支持库。

Espresso 2.0 released - 2014-12-20

Answer 2

更新2015年9月7日

这是非常令人沮丧，但我在Android支持库对特拉维斯CI成功运行了咖啡。这是为我工作的确切配置。特定的sdk和库版本号码很重要，所以不要更改它们，否则会遇到问题。支持注释的解决策略也是必要的，所以不要删除。由于Travis CI的Android支持仍处于测试阶段，这个答案可能会过时。检查Travis CI网站的更新here。

    lintOptions {

dependencies { 
    compile 'com.actionbarsherlock:actionbarsherlock:4.4.0@aar' 
    compile 'com.android.support:support-v4:20.+'

configurations.all { 
    resolutionStrategy { 
     // fail eagerly on version conflict (includes transitive dependencies) 
     // e.g. multiple different versions of the same dependency (group and name are equal) 
     failOnVersionConflict() 

     // force certain versions of dependencies (including transitive) 
     // *append new forced modules: 
     force 'com.android.support:support-annotations:20.+', 'com.squareup.retrofit:retrofit:1.4.1' 
     // *replace existing forced modules with new ones: 
     forcedModules = ['com.android.support:support-annotations:20.+', 'com.squareup.retrofit:retrofit:1.4.1'] 

     // cache dynamic versions for 10 minutes 
     cacheDynamicVersionsFor 10*60, 'seconds' 
     // don't cache changing modules at all 
     cacheChangingModulesFor 0, 'seconds' 
    } 
} 

如果收到error这样的：

PerformException: Error performing 'single click' on view 

将此代码添加到测试：

closeSoftKeyboard(); 
Thread.sleep(1000); 

例

public void testThatSuccessDialogIsShownWithValidCardInput() throws Exception { 
    onView(withId(R.id.card_number)) 
      .perform(typeText("4242424242424242")); 
    closeSoftKeyboard(); 
    Thread.sleep(1000); 
    onView(withId(R.id.card_exp_month)) 
      .perform(typeText("01")); 
    onView(withId(R.id.card_exp_year)) 
      .perform(typeText("20")); 
    onView(withId(R.id.card_cvc_code)) 
      .perform(typeText("313")); 
    closeSoftKeyboard(); 
    Thread.sleep(1000); 
    onView(withText("Submit")) 
      .perform(click()); 
    onView(withText("Success!")) 
      .check(matches(isDisplayed())); 
    onView(withText("OK")) 
      .perform(click()); 
    onView(withText("OK")) 
      .check(doesNotExist()); 
}
