如何在 Eclipse (JUnit4) 的同一个 Webdriver 中设置 Selenium 2.x 测试套件

Question

我已经在堆栈上筛选了一段时间的答案，并且遇到了一些似乎可以完成或至少接近的工作示例。

• Use same web driver throughout selenium suite
• Before and After Suite execution hook in jUnit 4.x
• JUnit Test Suite for Selenium 2

我想要做的就是将 selenium 测试用例导出为 JUnit4 文件，将它们带入 eclipse 并根据需要进行修改，然后能够在测试套件中添加或删除它。当测试套件运行时，它应该打开一个 webdriver 窗口并运行每个测试用例，就像它在基本 firefox 窗口上的 selenium IDE 中运行一样。唯一的问题似乎是 webdriver 类。我尝试在测试用例类之间引用它，这似乎可以让窗口保持打开而不会引发错误，但是第二个测试用例永远不会运行，就像它卡在一个循环中，或者停在@Before

import static org.junit.Assert.fail;

import java.util.concurrent.TimeUnit;

import org.junit.After;
import org.junit.Before;
import org.junit.runner.RunWith;
import org.junit.runners.Suite;
import org.junit.runners.Suite.SuiteClasses;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

@RunWith(Suite.class)
@SuiteClasses({TestCase1.class,TestCase2.class})
public class RunTestSuite {

}

    driver.get(baseUrl + "");

^^^ 测试用例 2 ^^^

感谢您提供的任何帮助！

Answer 1

您必须将驱动程序实例的访问修饰符从私有更改为静态公共，以便第二个类可以访问它。 还要确保两个类在同一个包中。

TestCase1 类应该是这样的

public static WebDriver driver;

我试过了，它很适合我。
