Question

我创建了pom.xml和一个示例文件Selenium2Example.java来设置Maven。我按照http://seleniumhq.org/docs/03_webdriver.html#chrome-driver

上的说明进行操作

但是我在运行Selenium2Example.java作为Java应用程序时收到错误“选择不包含主类型”。

这是我正在使用的pom.xml

        </dependencyManagement>
</project>

这是我正在使用的Selenium2Example.java：

package org.openqa.selenium.example;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.Chrome.ChromeDriver;
import org.openqa.selenium.support.ui.ExpectedCondition;
import org.openqa.selenium.support.ui.WebDriverWait;

public class Selenium2Example  {
    public static void main(String[] args) {
        // Create a new instance of the Chrome driver
        // Notice that the remainder of the code relies on the interface, 
        // not the implementation.
        WebDriver driver = new ChromeDriver();
        // And now use this to visit Google
        driver.get("http://www.google.com");
        // Alternatively the same thing can be done like this
        // driver.navigate().to("http://www.google.com");
        // Find the text input element by its name
        WebElement element = driver.findElement(By.name("q"));

        // Enter something to search for
        element.sendKeys("Cheese!");
        // Now submit the form. WebDriver will find the form for us from the element
        element.submit();

        // Check the title of the page
        System.out.println("Page title is: " + driver.getTitle());

        // Google's search is rendered dynamically with JavaScript.
        // Wait for the page to load, timeout after 10 seconds
        (new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {
            public Boolean apply(WebDriver d) {
                return d.getTitle().toLowerCase().startsWith("cheese!");
            }
        });
        // Should see: "cheese! - Google Search"
        System.out.println("Page title is: " + driver.getTitle());        
        //Close the browser
        driver.quit();
    }
}

运行时会出现以下错误以 - ＆gt;运行运行配置 - ＆gt; （在TestNG下选择Selenium2Example.java

错误是

Answer 1

首先，您做出了正确的决定（从我的观点来看）使用Maven，Java和WebDriver;）

您所做的就像是选择了错误的包或文件来运行！

这不是Selenium的问题，这是你的运行配置问题，你的IDE！

我猜你使用Eclipse？

尝试右键单击要运行的文件 - ＆gt;以 - ＆gt;运行Java应用程序

那应该解决你的问题...

如果您想使用Selenium WebDriver进行一些测试，请不要忘记选择测试框架。我会推荐JUnit甚至更好的TestNG ......

Answer 2

java代码没有问题。 Pl检查安装正确的驱动程序。尝试使用firefox驱动程序更改chrome驱动程序。

Selenium WebDriver首先设置了Java示例
