太愚蠢以至于无法将Appium Java客户端实现到Android Studio Project中 [英] Being too stupid to implement Appium Java client into Android Studio Project

问题描述

我最近开始使用Android Studio 3.1.2和SDK 19(Android 4.4)对我的第一个android项目进行编码.

I recently started coding my really first android project using Android Studio 3.1.2 and SDK 19 (Android 4.4).

当我遇到测试时，我想自动化我的UI测试，我打算用Appium的Java客户端编写该测试(服务器将在外部设置).为了获得包括所有驱动程序的java-Client，我在build.gradle(app):

When I came across testing I want to automate my UI-tests, which I plan to write with the java client of Appium (the server will be set up externally). In order to get the java-Client including all the drivers I added a dependency into the build.gradle(app):

implementation 'io.appium:java-client:6.1.0'

添加依赖项后，同步Gradle不会引起任何可识别的问题.现在，如果我尝试运行我的(非UI)测试之一，则在构建过程中我已经得到了DexArchiveBuilderException，并抛出了文字墙，这暗示了io.appium:java-client:6.1.0的几种资源需要较新的Android的API SDK:

Synching Gradle after adding the dependency didn't cause any recognizable problems. Now if I try to run one of my (non-UI) tests, I get a DexArchiveBuilderException already during the build process, throwing a wall of text, that somehow hints, that several resources of io.appium:java-client:6.1.0 require APIs from newer Android SDKs:

我几乎没有测试自动化方面的经验，因此正式的Appium文档并没有真正向我解释，如果可以使客户端在SDK 19上运行，如果是这样的话，该怎么做.你们中有谁知道该怎么做吗?还是我只是笨拙而忘记了集成过程中的必需步骤?谢谢.

I hardly have any experience in test automation, so the official Appium documentation doesn't really explain to me, if it's possible to make the client run on SDK 19 and if this is the case, how to do that. Does anyone of you guys know how to do this? Or am I just foolhardy and forgot a required step during the integration? Thanks in forward.

推荐答案

如果要使用Appium Java客户端自动化，最好将其测试项目与Android项目分开，并在Appium测试中使用内置的应用APK.

If you want to automate with Appium Java client, it's best to keep it's test project separate from the Android project and use your built app APK in the Appium test.

如果要将测试与Android项目保持在一起，最好使用Espresso，因为它是Android SDK的一部分.

If you want to keep your test together with the Android project, it's best to use Espresso as it's a part of the Android SDK.
