0. 概述

作用: 自动化Web应用程序以进行测试

官方网址: https://www.selenium.dev/zh-cn/

1. 爬虫使用

文档地址: https://www.selenium.dev/zh-cn/documentation/webdriver/

1.1 测试浏览器的版本

谷歌浏览器

Edge浏览器

Firefox开发版浏览器

Firefox正式版浏览器

1.2 下载驱动以及依赖

Java依赖下载

<!-- https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-java -->
<!-- 支持全部浏览器-->
<dependency>
  <groupId>org.seleniumhq.selenium</groupId>
  <artifactId>selenium-java</artifactId>
  <version>4.1.2</version>
</dependency>

驱动下载 == 必须跟浏览器的版本对应上,否则会报错哦

地址: https://www.selenium.dev/zh-cn/documentation/webdriver/getting_started/install_drivers/

当然驱动不想自己手动下载的话,让第三方驱动管理来帮你下自动适配你的浏览器所对应上的驱动。然后手动导入到IDEA上: https://github.com/bonigarcia/webdrivermanager**

驱动包管理器

3. 其他使用

3.1 监听弹框(alert、confirm、prompt)

    $(function(){

        });

        $("#testA").click(() => {
            //确定按钮
            // alert("点击a标签")

            //确定、取消按钮

            var content = prompt("神鼎飞丹砂发顺丰prompt弹框")

        WebDriverManager.firefoxdriver().setup();
        FirefoxDriver driver = new FirefoxDriver();

        driver.get("https://www.baidu.com/");

        actions.keyDown(Keys.SHIFT).sendKeys(kw, "abc")

        //【百度一下】 按钮
        WebElement su = driver.findElement(By.id("su"));
        su.click();
        //这句等价于上面的两句 == 回车即查询
        //kw.sendKeys(Keys.ENTER);

        //将查询结果打印出来
        WebElement searchResultContentElement = driver.findElement(By.id("content_left"));
        String searchResultContent = searchResultContentElement.getText();
        Console.log(searchResultContent);

        //关闭浏览器
        driver.quit();

    }

3.3 等待 - 某些节点需特定条件才会显示出来(需等待时间)

3.3.1 硬性等待 - 等待指定秒数 - Thread.sleep - 不灵活
//等待5秒后在执行后续代码
Thread.sleep(5000);
3.3.2 隐式等待(最多检索某秒数,直到找到为止,超时仍未找到则报错) - 一旦设置,所有节点的查找都会有隐式等待的时间

没设置隐式等待的结果 - 报错

设置隐式等待的结果 - 成功运行

4. 浏览器插件 - 动作录制以及重放

4.1 下载插件

//去谷歌、edge浏览器的插件商场上找插件
selenium ide

//去火狐找
selenium ide
Katalon Recorder (Selenium tests generator)

4.2 设置浏览器防止重放失败

4.3 动作录制以及重放 - 自行去B站看视频(写博客没啥意义)
