java - 当我在 Eclipse 中运行 Maven 项目时，出现 org.apache.maven.surefire.util.SurefireReflectionException

Question

这是我第一次在 eclipse 中使用 Maven 和 selenium。所以我使用 Mkyong 的例子:http://www.mkyong.com/maven/how-to-create-a-java-project-with-maven/我用一个简单的 gmail 登录测试替换了 AppTest.java。

所以我的 pom.xml 是:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

            <version>4.11</version>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>2.3.2</version>
                <configuration>
                    <source>1.6</source>
                    <target>1.6</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

我的 AppTest.java 是:

package com.mkyong;

import java.util.regex.Pattern;
import java.util.concurrent.TimeUnit;

import org.junit.*;

import static org.junit.Assert.*;
import static org.hamcrest.CoreMatchers.*;

import org.openqa.selenium.*;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.Select;

public class AppTest {
  private WebDriver driver;
  private String baseUrl;
  private boolean acceptNextAlert = true;
  private StringBuffer verificationErrors = new StringBuffer();

  @Before
  public void setUp() throws Exception {
    //driver = new FirefoxDriver();
    driver = new ChromeDriver();
    baseUrl = "https://accounts.google.com/";
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
  }

  @Test
  public void testGmail() throws Exception {
    driver.get("http://www.gmail.com");
    driver.findElement(By.id("Email")).clear();
    driver.findElement(By.id("Email")).sendKeys("emailaddress");
    driver.findElement(By.id("Passwd")).clear();
    driver.findElement(By.id("Passwd")).sendKeys("password");
    driver.findElement(By.id("signIn")).click();
    /*driver.findElement(By.cssSelector("span.gb_4.gbii")).click();
    driver.findElement(By.id("gb_71")).click();*/
  }

  @After
  public void tearDown() throws Exception {
    driver.quit();
    String verificationErrorString = verificationErrors.toString();
    if (!"".equals(verificationErrorString)) {
      fail(verificationErrorString);
    }
  }

  private boolean isElementPresent(By by) {
    try {
      driver.findElement(by);
      return true;
    } catch (NoSuchElementException e) {
      return false;
    }
  }

  private boolean isAlertPresent() {
    try {
      driver.switchTo().alert();
      return true;
    } catch (NoAlertPresentException e) {
      return false;
    }
  }

  private String closeAlertAndGetItsText() {
    try {
      Alert alert = driver.switchTo().alert();
      String alertText = alert.getText();
      if (acceptNextAlert) {
        alert.accept();
      } else {
        alert.dismiss();
      }
      return alertText;
    } finally {
      acceptNextAlert = true;
    }
  }
}

当我右键单击该项目并单击 maven-install 来运行时，我收到以下错误:

谁能帮忙解决这个问题，谢谢

使用maven时不要混合eclipse类路径提供程序，您需要添加

<dependency>
  <groupId>org.seleniumhq.selenium</groupId>
  <artifactId>selenium-chrome-driver</artifactId>
  <version>LATEST_COMPATIBLE_VERSION</version>
  <scope>test</scope>
</dependency>

到您的 pom.xml，它定义您的项目依赖于此 Artifact 进行测试
