一、Selenium简介
Selenium是一个用于Web应用程序自动化测试工具。Selenium测试直接运行在浏览器中,就像真正的用户在
操作一样。支持的浏览器包括IE(7, 8, 9, 10, 11),Mozilla Firefox,Safari,Google Chrome,Opera等。
适用于自动化测试,js动态爬虫(破解反爬虫)等领域。
Selenium的核心Selenium Core基于JsUnit,
完全由JavaScript编写,因此可以用于任何支持JavaScript的浏览器上。
selenium可以模拟真实浏览器,自动化测试工具,支持多种浏览器。
二、Selenium组成
Selenium IDE:嵌入到Firefox浏览器中的一个插件,实现简单的浏览器操作录制与回放功能,主要用于快速创建BUG及重现脚本,可转化为多种语言
Selenium RC: 核心组件,支持多种不同语言编写自动化测试脚本,通过其服务器作为代理服务器去访问应用,达到测试的目的
Selenium WebDriver(重点):一个浏览器自动化框架,它接受命令并将它们发送到浏览器。它是通过特定于浏览器的驱动程序实现的。它直接与浏览器通信并对其进行控制。Selenium WebDriver支持各种编程语言,如Java、C# 、PHP、Python、Perl、Ruby
Selenium grid:测试辅助工具,用于做分布式测试,可以并行执行多个测试任务,提升测试效率。
三、Selenium特点
开源、免费
多浏览器支持:FireFox、Chrome、IE、Opera、Edge;
多平台支持:Linux、Windows、MAC;
多语言支持:Java、Python、Ruby、C#、JavaScript、C++;
对Web页面有良好的支持;
简单(API 简单)、灵活(用开发语言驱动);
支持分布式测试用例执行。
四、案例演示
1.下载驱动包
谷歌下载地址:http://chromedriver.storage.googleapis.com/index.htm
如果在下载地址中找不到与自己浏览器完全匹配的版本,可以用相近的版本
2.创建项目并导入依赖
<dependency><groupId>org.seleniumhq.selenium</groupId><artifactId>selenium-java</artifactId><version>3.141.59</version></dependency><dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-java</artifactId> <version>3.141.59</version> </dependency><dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-java</artifactId> <version>3.141.59</version> </dependency>
3.基础配置
//设置驱动System.setProperty("webdriver.chrome.driver","C:\\Users\\Administrator\\AppData\\Local\\Google\\Chrome\\Application\\chromedriver.exe");//创建驱动WebDriver driver=new ChromeDriver();//与将要爬取的网站建立连接driver.get("https://www.baidu.com/");//设置驱动 System.setProperty("webdriver.chrome.driver","C:\\Users\\Administrator\\AppData\\Local\\Google\\Chrome\\Application\\chromedriver.exe"); //创建驱动 WebDriver driver=new ChromeDriver(); //与将要爬取的网站建立连接 driver.get("https://www.baidu.com/");//设置驱动 System.setProperty("webdriver.chrome.driver","C:\\Users\\Administrator\\AppData\\Local\\Google\\Chrome\\Application\\chromedriver.exe"); //创建驱动 WebDriver driver=new ChromeDriver(); //与将要爬取的网站建立连接 driver.get("https://www.baidu.com/");
4.案例演示
1.元素选择方式
class:
List<WebElement> elements = driver.findElements(By.className("hotsearch-item"));for (WebElement element : elements) {System.out.println(element.getText());}List<WebElement> elements = driver.findElements(By.className("hotsearch-item")); for (WebElement element : elements) { System.out.println(element.getText()); }List<WebElement> elements = driver.findElements(By.className("hotsearch-item")); for (WebElement element : elements) { System.out.println(element.getText()); }
ID:

Name:
WebElement tn = driver.findElement(By.name("tn"));System.out.println(tn.getAttribute("value"));WebElement tn = driver.findElement(By.name("tn")); System.out.println(tn.getAttribute("value"));WebElement tn = driver.findElement(By.name("tn")); System.out.println(tn.getAttribute("value"));
tag:
List<WebElement> input = driver.findElements(By.tagName("input"));for(WebElement webElement:input){String value = webElement.getAttribute("value");System.out.println(value);}List<WebElement> input = driver.findElements(By.tagName("input")); for(WebElement webElement:input){ String value = webElement.getAttribute("value"); System.out.println(value); }List<WebElement> input = driver.findElements(By.tagName("input")); for(WebElement webElement:input){ String value = webElement.getAttribute("value"); System.out.println(value); }
link:
List<WebElement> elements = driver.findElements(By.linkText("地图"));for (WebElement element : elements){System.out.println(element.getText());}List<WebElement> elements = driver.findElements(By.linkText("地图")); for (WebElement element : elements){ System.out.println(element.getText()); }List<WebElement> elements = driver.findElements(By.linkText("地图")); for (WebElement element : elements){ System.out.println(element.getText()); }
Partial link选择(a标签文本内容模糊匹配):
List<WebElement> elements = driver.findElements(By.partialLinkText("中国"));for (WebElement element : elements){System.out.println(element.getText());}List<WebElement> elements = driver.findElements(By.partialLinkText("中国")); for (WebElement element : elements){ System.out.println(element.getText()); }List<WebElement> elements = driver.findElements(By.partialLinkText("中国")); for (WebElement element : elements){ System.out.println(element.getText()); }
css选择器:
List<WebElement> elements = driver.findElements(By.cssSelector("#hotsearch-content-wrapper > li:nth-child(even)"));for (WebElement element : elements){System.out.println(element.getText());List<WebElement> elements = driver.findElements(By.cssSelector("#hotsearch-content-wrapper > li:nth-child(even)")); for (WebElement element : elements){ System.out.println(element.getText());List<WebElement> elements = driver.findElements(By.cssSelector("#hotsearch-content-wrapper > li:nth-child(even)")); for (WebElement element : elements){ System.out.println(element.getText());
xpath选择:
WebElement element = driver.findElement(By.xpath("//*[@id=\"kw\"]"));System.out.println(element.getAttribute("class"));WebElement element = driver.findElement(By.xpath("//*[@id=\"kw\"]")); System.out.println(element.getAttribute("class"));WebElement element = driver.findElement(By.xpath("//*[@id=\"kw\"]")); System.out.println(element.getAttribute("class"));
2.在文本框中输入内容
WebElement kw = driver.findElement(By.id("kw"));kw.sendKeys("java");WebElement button=driver.findElement(By.id("su"));button.click();WebElement kw = driver.findElement(By.id("kw")); kw.sendKeys("java"); WebElement button=driver.findElement(By.id("su")); button.click();WebElement kw = driver.findElement(By.id("kw")); kw.sendKeys("java"); WebElement button=driver.findElement(By.id("su")); button.click();
3.获取单个元素
WebElement element = driver.findElement(By.name("ie"));System.out.println(element.getAttribute("value"));WebElement element = driver.findElement(By.name("ie")); System.out.println(element.getAttribute("value"));WebElement element = driver.findElement(By.name("ie")); System.out.println(element.getAttribute("value"));
4.获取多个元素
List<WebElement> elements = driver.findElements(By.partialLinkText("大"));for (WebElement element : elements){System.out.println(element.getText());}List<WebElement> elements = driver.findElements(By.partialLinkText("大")); for (WebElement element : elements){ System.out.println(element.getText()); }List<WebElement> elements = driver.findElements(By.partialLinkText("大")); for (WebElement element : elements){ System.out.println(element.getText()); }
