和我一起学 Selenium WebDriver（2）――入门篇

【1. 加入 jUnit】

Selenium 环境搞定，接下来就要想办法让我们的测试步入正轨了，对于 java
来说，用上 jUnit 是很方便的，maven 项目加入 jUnit 也是轻而易举，稍微修改一下 pom.xml 就可以了

Xml代码

把上一篇中测试 FireFox 的代码拿来按照 jUnit
的结构适当修改一下，就可以直接利用 jUnit 进行测试了

Java代码







package lesson2;

import java.util.List;

import org.junit.AfterClass;

import org.junit.BeforeClass;

import org.junit.Test;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.firefox.FirefoxDriver;

import org.openqa.selenium.support.ui.ExpectedCondition;

import org.openqa.selenium.support.ui.WebDriverWait;

public class ExampleJunit {

static WebDriver driver;

@BeforeClass

public static void init() {

System.out.println("init...");

// 如果你的 FireFox 没有安装在默认目录，那么必须在程序中设置

System.setProperty("webdriver.firefox.bin", "D:\\Program Files\\Mozilla Firefox\\firefox.exe");

// 创建一个 FireFox 的浏览器实例

driver = new FirefoxDriver();

}

@Test

public void test() {

// 让浏览器访问 zTree Demo

driver.get("http://www.ztree.me/v3/demo/cn/core/standardData.html");

// 等待 zTree 初始化完毕，Timeout 设置10秒

(new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {

public Boolean apply(WebDriver d) {

WebElement element = driver.findElement(By.id("treeDemo"));

return element.findElement(By.tagName("a")) != null;

}

});

WebElement element = driver.findElement(By.id("treeDemo"));

List<WebElement> elements = element.findElements(By.tagName("li"));

// 显示生成的节点DOM 数量

System.out.println("treeNode DOM length = " + elements.size());

}

@AfterClass

public static void destory() {

System.out.println("destory...");

//关闭浏览器

driver.quit();

}

}
