android - 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 任务并执行我的所有单元测试。我已经能够成功设置它。我现在正尝试使用 Espresso 构建一些功能测试，目前我在设置 Travis 时遇到了很多困难，以便我的 espresso 测试可以与 Travis 的模拟器交互。我该如何设置 Travis，使其模拟器的工作方式与我在本地工作站上使用的模拟器完全一样？

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 &

这非常令人沮丧，但我在 Android 支持库中获得了 Espresso，以便在 Travis CI 上成功运行。这是对我有用的确切配置。具体的 sdk 和库版本号很重要，所以不要更改它们，否则会遇到问题。支持注释的解析策略也是必要的，所以也不要删除它。由于 Travis CI 的 android 支持仍处于测试阶段，这个答案可能会过时。查看 Travis CI 网站以获取更新 here .

.travis.yml

    }
}

android {
    compileSdkVersion 20
    buildToolsVersion "22.0.1"

    defaultConfig {

        exclude 'META-INF/NOTICE'
    }

    lintOptions {
        abortOnError false
    }
}

    compile 'com.actionbarsherlock:actionbarsherlock:4.4.0@aar'

        // 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'
    }
}

如果您收到 error像这样:

PerformException: Error performing 'single click' on view

添加此代码进行测试:

closeSoftKeyboard();
Thread.sleep(1000);

例子

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());
}
