selenium测试(Java)-- 显式等待(九)

转自:https://www.cnblogs.com/moonpool/p/5668571.html

显式等待可以使用selenium预置的判断方法,也可以使用自定义的方法。

 1 package com.test.elementwait;

 3 import org.openqa.selenium.By;
 4 import org.openqa.selenium.WebDriver;
 5 import org.openqa.selenium.firefox.FirefoxDriver;
 6 import org.openqa.selenium.support.ui.ExpectedCondition;
 7 import org.openqa.selenium.support.ui.ExpectedConditions;
 8 import org.openqa.selenium.support.ui.WebDriverWait;

10 public class ExplicitWait {
11 
12     public static void main(String[] args) {
13         WebDriver driver = new FirefoxDriver();
14         driver.get("http://www.baidu.com");
15         driver.manage().window().maximize();
16 
17         //标题是不是“百度一下,你就知道”
18         new WebDriverWait(driver,5).until(ExpectedConditions.titleIs("百度一下,你就知道"));
19         //标题是不是包含“百度一下”
20         new WebDriverWait(driver,5).until(ExpectedConditions.titleContains("百度一下"));
21         //判断该元素是否被加载在DOM中,并不代表该元素一定可见        
22         new WebDriverWait(driver,5).until(ExpectedConditions.presenceOfElementLocated(By.xpath("//*[@id='kw']")));
23         //判断元素(定位后)是否可见
24         new WebDriverWait(driver,5).until(ExpectedConditions.visibilityOf(driver.findElement(By.xpath("//*[@id='kw']"))));
25         //判断元素是否可见(非隐藏,并且元素的宽和高都不等以0)
26         new WebDriverWait(driver,5).until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id='kw']")));
27         //只要存在一个就是true
28         ExpectedConditions.presenceOfAllElementsLocatedBy(By.xpath("//*[@id='kw']"));
29         //元素中的text是否包含语气的字符串
30         ExpectedConditions.textToBePresentInElementLocated(By.xpath("//*[@id='kw']"), "百度一下");
31         //元素的value属性中是否包含语气的字符串
32         ExpectedConditions.textToBePresentInElementValue(By.xpath("//*[@id='kw']"), "***");
33         //判断该表单是否可以切过去,可以就切过去并返回true,否则放回false
34         ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.id("**"));
35         //判断某个元素是否不存在于DOM或不可见
36         ExpectedConditions.invisibilityOfElementLocated(By.xpath("//*[@id='kw']"));
37         //判断元素是否可以点击
38         ExpectedConditions.elementToBeClickable(By.xpath("//*[@id='kw']"));
39         //等到一个元素从DOM中移除
40         ExpectedConditions.stalenessOf(driver.findElement(By.xpath("//*[@id='kw']")));
41         //判断某个元素是否被选中,一般用在下拉列表
42         ExpectedConditions.elementToBeSelected(By.xpath("//*[@id='kw']"));
43         //判断某个元素的选中状态是否符合预期
44         ExpectedConditions.elementSelectionStateToBe(By.xpath("//*[@id='kw']"), true);
45         //判断某个元素(已定位)的选中状态是否符合预期
46         ExpectedConditions.elementSelectionStateToBe(driver.findElement(By.xpath("//*[@id='kw']")), false);
47         //判断页面中是否存在alert
48         new WebDriverWait(driver,5).until(ExpectedConditions.alertIsPresent());
49         //--------------------自定义判断条件-----------------------------
50         WebDriverWait wait = new WebDriverWait(driver, 3);
51         wait.until(new ExpectedCondition<Boolean>() {
52              public Boolean apply(WebDriver driver) {
53                  return !driver.findElement(By.xpath("//*[@id='kw']")).getAttribute("class").contains("x-form-invalid-field");
54                              }
55                  });
56         
57     }
58 
59 }

注:

1.除了以上内容,selenium还提供了很多预置的判断方法。

2.这些判断方法,在超出时间限制时就会抛出异常。
