无法使用 Appium + Android Studio 3.0 + Java 8 [英] Failed to use Appium + Android Studio 3.0 + Java 8
问题描述
我正在尝试使用 appium java 客户端进行我的 Android UI 测试.但是，我无法让它运行.这是我的 build.gradle 和我的错误信息.

尽管
添加库到您的项目 app 或 my_feature gradle 文件.Appium 和 Selenium 版本应该注意避免没有这样的方法错误" - 查看答案:
依赖项{androidTestImplementation 'junit:junit:4.12'androidTestImplementation 'io.appium:java-client:5.0.1'androidTestImplementation 'org.seleniumhq.selenium:selenium-java:3.4.0'}在您的 Android 项目 .../src/androidTest/java/ 文件夹中创建 JUnit 功能测试类.您也可以使用简单的 JUnit 测试包装器.对于测试需求，您可以在 Android 项目中使用 main 方法创建一个单独的 Java 项目或 Java 类，但将 Appium 测试集成到 Android Studio 测试功能中会更方便.还要检查您是否没有导入其他测试库，也不要在您的代码中混合使用它(例如，@Test 可用于 TestNG 以及 JUnit).在您的方法中使用 Appium Inspector 自动生成的代码，例如:
包 com.example.my_project;导入 org.junit.After;导入 org.junit.Before;导入 org.junit.Test;导入 org.openqa.selenium.remote.DesiredCapabilities；导入 java.net.MalformedURLException;导入 java.net.URL;导入 io.appium.java_client.MobileElement;导入 io.appium.java_client.android.AndroidDriver;公共类 SampleTest {私有 AndroidDriver司机;@测试公共无效测试计划()抛出 MalformedURLException {设置();testWorkUnit_WithCertainState_ShouldDoSomething();abotherTestWorkUnit_WithCertainState_ShouldDoSomething();拆除();}公共无效设置()抛出 MalformedURLException {DesiredCapabilities requiredCapabilities = 新的 DesiredCapabilities();URL remoteUrl = new URL("http://localhost:4723/wd/hub");requiredCapabilities.setCapability("平台名称",安卓");requiredCapabilities.setCapability(设备名称"，"安卓模拟器");requiredCapabilities.setCapability("应用程序包","com.example.my_project");requiredCapabilities.setCapability("应用活动","com.example.my_project.MyActivity");司机 =新的 AndroidDriver<>(远程网址，所需的能力)；}public void testWorkUnit_WithCertainState_ShouldDoSomething() {移动元素 el1 =driver.findElementById("com.example.my_project:id/urlField");el1.sendKeys("example.com");}公共无效撕裂(){驱动程序退出()；}} 至于代码中的注解:@Before 和 @After 用于类中每个测试用例的前后(@BeforeClass 和@AfterClass 需要静态且不方便).因此，它每次都会重新启动应用程序，并且不便于链接测试.所以最好有一个方法用@Test注解，这样会调用其他没有注解的方法进行设置，按要求顺序做测试用例，完成.

Can anyone check for me to see whether I have correct and sufficient dependencies? There are so many tutorials for adding Appium but none of them works for me.
On the other hand, if I can use Java 7 to integrate with Appium, how should I do instead?
Although Appium is well documented and versatile, the working combination for Android Studio took me a working day. In my case it was a substitution for Espresso, because it doesn't currently support multi-feature testing for Instant Apps. Also Appium gives wider possiblities to test app integration, like Firebase messaging, using other apps etc.
- Install Appium Server as UI.
- Setup Appium Server for your localhost:
- Host: 127.0.0.1 Port: 4723
- Edit Configurations -> Set ANDROID_HOME and JAVA_HOME paths.
- Start server. You'll see a console, leave this window open.
- Run Android Emulator from Android Studio.
- Start Appium Session for your Emulator in Appium UI (File -> New Session Window):
- If everything goes fine and console shows no log errors, then Appium Inspector window will open. Also your app will be run in the Emulator. In Inspector find elements by clicking on a screenshot. Record your actins with buttons atop and get autogenerated code:
Add libraries to your project
appormy_featuregradle file. Appium and Selenium versions should watch to avoid "No such method error" - see an answer:dependencies { androidTestImplementation 'junit:junit:4.12' androidTestImplementation 'io.appium:java-client:5.0.1' androidTestImplementation 'org.seleniumhq.selenium:selenium-java:3.4.0' }Create a JUnit functional test class in your Android project
.../src/androidTest/java/folder. You can use simple JUnit test wrapper as well. For testing needs you could have created a separate Java project or Java class withmainmethod inside your Android project, but it is more convenient to integrate Appium tests into Android Studio testing features. Also check that you don't import other testing libraries and don't use it as a mix in your code (e.g. @Test is available for TestNG as well as for JUnit). Use autogenerated code from Appium Inspector inside your methods like:package com.example.my_project; import org.junit.After; import org.junit.Before; import org.junit.Test; import org.openqa.selenium.remote.DesiredCapabilities; import java.net.MalformedURLException; import java.net.URL; import io.appium.java_client.MobileElement; import io.appium.java_client.android.AndroidDriver; public class SampleTest { private AndroidDriver<MobileElement> driver; @Test public void testPlan() throws MalformedURLException { setUp(); testWorkUnit_WithCertainState_ShouldDoSomething(); abotherTestWorkUnit_WithCertainState_ShouldDoSomething(); tearDown(); } public void setUp() throws MalformedURLException { DesiredCapabilities desiredCapabilities = new DesiredCapabilities(); URL remoteUrl = new URL("http://localhost:4723/wd/hub"); desiredCapabilities.setCapability( "platformName", "Android"); desiredCapabilities.setCapability( "deviceName", "Android Emulator"); desiredCapabilities.setCapability( "appPackage", "com.example.my_project"); desiredCapabilities.setCapability( "appActivity", "com.example.my_project.MyActivity"); driver = new AndroidDriver<>( remoteUrl, desiredCapabilities); } public void testWorkUnit_WithCertainState_ShouldDoSomething() { MobileElement el1 = driver.findElementById( "com.example.my_project:id/urlField"); el1.sendKeys("example.com"); } public void tearDown() { driver.quit(); } }
As for annotations in code: @Before and @After are used before and after each test case in your class (@BeforeClass and @AfterClass requires static and is not handlful). Therefore it restarts the app every time as a result and its not convenient for chaining tests. So it's better to have one method annotated with @Test, which will call other unannotated methods for setting up, doing test case in required order and finishing.
