Question

我正在尝试自动化简单的Web应用程序，为此，我正在使用带有Selenium和Java的Page Object Model Pattern，我的Maven Pom依赖项如下所示：

<dependencies>
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-firefox-driver</artifactId>
        <version>3.12.0</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-java -->
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>3.14.0</version>
    </dependency>

    <dependency>
        <groupId>org.testng</groupId>
        <artifactId>testng</artifactId>
        <version>6.9.13.5</version>
    </dependency>

    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-ie-driver</artifactId>
        <version>3.0.0-beta4</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/log4j/log4j -->
    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-chrome-driver -->
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-chrome-driver</artifactId>
        <version>3.12.0</version>
    </dependency>

</dependencies>

我的页面对象类如下：

public class Page {
    public Page(WebDriver driver) {
        PageFactory.initElements(driver, this);
    }
    @FindBy(linkText = "Players")
    private WebElement playersLink;

    public boolean isPlayersLinkVisible(){
        return playersLink.isDisplayed();
    }
}

我的测试如下：

public class Test{
  @Test
  public void test(){
        WebDriver driver = new ChromeDriver();
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        driver.get(URL);
        Page page = new Page(driver);
        System.out.println(page.isPlayersLinkVisible());
  }
}

但是我遇到了这个异常，无法弄清楚为什么？

java.lang.NoClassDefFoundError: org/openqa/selenium/WrapsElement

at org.openqa.selenium.support.pagefactory.DefaultFieldDecorator.proxyForLocator(DefaultFieldDecorator.java:101)
at org.openqa.selenium.support.pagefactory.DefaultFieldDecorator.decorate(DefaultFieldDecorator.java:62)
at org.openqa.selenium.support.PageFactory.proxyFields(PageFactory.java:113)
at org.openqa.selenium.support.PageFactory.initElements(PageFactory.java:105)
at org.openqa.selenium.support.PageFactory.initElements(PageFactory.java:92)

Answer 1

我发现，显然存在不兼容的依赖关系，我删除了不必要的依赖关系，只留下了我需要的依赖关系：

<dependencies>

    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>3.14.0</version>
    </dependency>

    <dependency>
        <groupId>org.testng</groupId>
        <artifactId>testng</artifactId>
        <version>6.9.13.5</version>
    </dependency>

    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>

</dependencies>

Answer 2

我遇到了这个问题，因为硒支持版本与我使用的其他硒库不同。当所有硒库（包括pom.xml中的硒支持库）使用相同版本时，此问题已解决。

尝试在Java中使用硒中的PageFactory时出现异常
