從這一節開始，不講基本的頁面操做了，開始爲搭建框架作準備，例如如何封裝查找元素的通用方法，這個方法封裝好後其它類中均可以使用封裝好的這個方法來查找元素，提升代碼的複用性，方便後期維護。css

1、首先咱們須要封裝一個可以定位單個或多個元素的類html

 5 import org.openqa.selenium.By;
 6 import org.openqa.selenium.WebDriver;
 7 import org.openqa.selenium.WebElement;

 9 public class GenericMethods {
10     
11     WebDriver driver;
12 //    建立一個構成方法，用於初始化對象
13     public GenericMethods(WebDriver driver) {
14         this.driver = driver;
15     }
16     
17 //    查找單個元素
18     public WebElement getElement(String type,String locator) {
19         if(type.equals("id")) {
20             System.out.println("用id查找元素："+locator);
21             return this.driver.findElement(By.id(locator));
22         }else if(type.equals("xpath")) {
23             System.out.println("用xpath查找元素："+locator);
24             return this.driver.findElement(By.xpath(locator));
25         }else if(type.equals("name")) {
26             System.out.println("用name查找元素："+locator);
27             return this.driver.findElement(By.name(locator));
28         }else if(type.equals("cssSelector")) {
29             System.out.println("用cssSelector查找元素："+locator);
30             return this.driver.findElement(By.cssSelector(locator));
31         }else if(type.equals("cssSelector")) {
32             System.out.println("用cssSelector查找元素："+locator);
33             return this.driver.findElement(By.cssSelector(locator));
34         }else if(type.equals("linkText")) {
35             System.out.println("用linkText查找元素："+locator);
36             return this.driver.findElement(By.linkText(locator));
37         }else if(type.equals("partialLinkText")) {
38             System.out.println("用partialLinkText查找元素："+locator);
39             return this.driver.findElement(By.partialLinkText(locator));
40         }else if(type.equals("tagName")) {
41             System.out.println("用tagName查找元素："+locator);
42             return this.driver.findElement(By.tagName(locator));
43         }else {
44             System.out.println("定位的路徑不支持");
45             return null;
46         }
47     }
48     
49 //    查找多個元素
50     public List<WebElement> getElementList(String type,String locator) {
51         if(type.equals("id")) {
52             System.out.println("用id查找元素："+locator);
53             return this.driver.findElements(By.id(locator));
54         }else if(type.equals("xpath")) {
55             System.out.println("用xpath查找元素："+locator);
56             return this.driver.findElements(By.xpath(locator));
57         }else if(type.equals("name")) {
58             System.out.println("用name查找元素："+locator);
59             return this.driver.findElements(By.name(locator));
60         }else if(type.equals("cssSelector")) {
61             System.out.println("用cssSelector查找元素："+locator);
62             return this.driver.findElements(By.cssSelector(locator));
63         }else if(type.equals("cssSelector")) {
64             System.out.println("用cssSelector查找元素："+locator);
65             return this.driver.findElements(By.cssSelector(locator));
66         }else if(type.equals("linkText")) {
67             System.out.println("用linkText查找元素："+locator);
68             return this.driver.findElements(By.linkText(locator));
69         }else if(type.equals("partialLinkText")) {
70             System.out.println("用partialLinkText查找元素："+locator);
71             return this.driver.findElements(By.partialLinkText(locator));
72         }else if(type.equals("tagName")) {
73             System.out.println("用tagName查找元素："+locator);
74             return this.driver.findElements(By.tagName(locator));
75         }else {
76             System.out.println("定位的路徑不支持");
77             return null;
78         }    
79     }
80 }

2、對圖中的單個輸入框進行操做，輸入「測試」（圖中的頁面是本地的網頁，小夥伴們若是須要能夠加入555191854下載或者找其它的網站進行練習）java

package usefulmethods;

import java.util.concurrent.TimeUnit;

import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

class GenericMethodsDemo {
    private WebDriver driver;
    private String url;
//    建立一個GenericMethods類的引用
    private GenericMethods gm;

    @BeforeEach
    public void setUp() throws Exception {
        driver = new ChromeDriver();
//        實例化查找元素的方法
        gm = new GenericMethods(driver);
        url = "C:\\\\Users\\\\acer\\\\eclipse-workspace\\\\SeleniumPractise\\\\PracticePage.html";
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        driver.manage().window().maximize();
    }

    @Test
    public void test() {
        driver.get(url);
//        經過調用GenericMethods類中的getElement方法，傳入查找元素的方式和路徑
        WebElement el = gm.getElement("cssSelector", "#name");
        el.sendKeys("測試");
    }
    
    @AfterEach
    public void tearDown() throws Exception {
        Thread.sleep(2000);
        driver.quit();
    }
}

運行結果爲：chrome

3、定位多個輸入框api

27     }

29     @Test
30     public void test() {
31         driver.get(url);
32 //        經過調用GenericMethods類中的getElementList方法，傳入查找元素的方式和路徑
33         List<WebElement> el = gm.getElementList("xpath", "//input[@type='text']");
34         int size = el.size();
35         System.out.println("獲取到的元素長度爲："+size);
36     }
37     
38     @AfterEach
39     public void tearDown() throws Exception {
40         Thread.sleep(2000);
41         driver.quit();
42     }
43 }
