二十七、常用的显式等待

显式等待比隐式等待更节约测试脚本执行的时间，推荐尽量使用显式等待方式来判断页面元素是否存在。使用ExpectedConditions类中自带的方法，可以进行显式等待的判断。显式等待可以自定义等待的条件，用于更加复杂的页面元素状态判断。常用的显式等待条件如下表所示：

等待的条件 WebDriver方法
页面元素是否在页面上可用（enabled） elementToBeClickable(By locator)
页面元素处于被选中状态 elementToBeSelected(WebElement element)
页面元素在页面中存在 presenceOfElementLocated(By locator)
在页面元素中是否包含特定的文本 textToBePresentInElement(By locator)
页面元素值 textToBePresentInElementValue(By locator,java.lang.String text)
标题（title） titleContains(java.lang.String title)

只有满足显式等待的条件要求，测试代码才会继续向后执行后续的测试逻辑。当显式等待条件未被满足的时候，在设定的最大显式等待时间阈值内，会停在当前代码位置进行等待，直到设定的等待条件被满足，才能继续执行后续的测试逻辑。如果超过设定的最大显式等待时间阈值，则测试程序会抛出异常，测试用例被认为执行失败。

二十九、判断页面元素是否存在

被测试网页的网址：

http://www.sogou.com

Java语言版本的API实例代码：

 1 package test;
 2 
 3 import org.testng.annotations.Test;
 4 
 5 import org.testng.annotations.BeforeMethod;
 6 
 7 import org.openqa.selenium.By;
 8 import org.openqa.selenium.NoSuchElementException;
 9 import org.openqa.selenium.WebDriver;
10 import org.openqa.selenium.WebElement;

15 public class ChormeOpen {
16     WebDriver driver;
17     String url = "http://www.sogou.com";
18     
19     private Boolean IsElementPresent(By by){
20         try {
21             driver.findElement(by);
22             return true;
23         } catch (NoSuchElementException e) {

26         }
27     }
28     @Test
29     public void opentest() {
30         driver.get(url);
31         if(IsElementPresent(By.id("query"))){
32             WebElement searchInputbox = driver.findElement(By.id("query"));
33             if(searchInputbox.isEnabled()==true){
34                 searchInputbox.sendKeys("sogou找到了");
35             }
36         }else{
37             Assert.fail("元素未被找到");
38         }
39         try {
40             Thread.sleep(3000);
41         } catch (InterruptedException e) {
