从生成 ElementnotSelectableException 的 appium 执行测试

Question

虽然运行我在 appium 中使用 maven 和 testng 测试用例，但我遇到了这个错误，不明白为什么会这样。我正在使用 Intellij，下面是错误和 pom.xml 文件

Disconnected from the target VM, address: '127.0.0.1:51681', transport: 'socket'

Answer 1

这很可能是由于 Selenium 服务器与 Phantom JS 不兼容造成的，因为您使用的是测试版。

因此请尝试将其升级到下一个稳定版，例如通过 pom.xml 文件中的以下行：

<dependency>
  <groupId>org.seleniumhq.selenium</groupId>
  <artifactId>selenium-java</artifactId>
  <version>3.5.2</version>
  <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-chrome-driver</artifactId>
    <version>3.5.2</version>
</dependency>
<dependency>
  <groupId>com.codeborne</groupId>
  <artifactId>phantomjsdriver</artifactId>
  <version>1.3.0</version>
</dependency>

然后运行 mvn dependency:tree 构建并显示此项目的依赖关系树。
