selenium測試(Java)-- 顯式等待(九)

 

顯式等待能夠使用selenium預置的判斷方法,也能夠使用自定義的方法。app

13         WebDriver driver = new FirefoxDriver();
14         driver.get("http://www.baidu.com");
15         driver.manage().window().maximize();
16 
17         //標題是否是「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         //標題是否是包含「百度一下」
20         new WebDriverWait(driver,5).until(ExpectedConditions.titleContains("百度一下"));
21         //判斷該元素是否被加載在DOM中,並不表明該元素必定可見        
22         new WebDriverWait(driver,5).until(ExpectedConditions.presenceOfElementLocated(By.xpath("//*[@id='kw']")));
23         //判斷元素(定位後)是否可見
24         new WebDriverWait(driver,5).until(ExpectedConditions.visibilityOf(driver.findElement(By.xpath("//*[@id='kw']"))));
25         //判斷元素是否可見(非隱藏,而且元素的寬和高都不等以0)
26         new WebDriverWait(driver,5).until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id='kw']")));
27         //只要存在一個就是true
28         ExpectedConditions.presenceOfAllElementsLocatedBy(By.xpath("//*[@id='kw']"));
29         //元素中的text是否包含語氣的字符串
30         ExpectedConditions.textToBePresentInElementLocated(By.xpath("//*[@id='kw']"), "百度一下");
31         //元素的value屬性中是否包含語氣的字符串
32         ExpectedConditions.textToBePresentInElementValue(By.xpath("//*[@id='kw']"), "***");
33         //判斷該表單是否能夠切過去,能夠就切過去並返回true,不然放回false
34         ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.id("**"));
35         //判斷某個元素是否不存在於DOM或不可見
36         ExpectedConditions.invisibilityOfElementLocated(By.xpath("//*[@id='kw']"));
37         //判斷元素是否能夠點擊
38         ExpectedConditions.elementToBeClickable(By.xpath("//*[@id='kw']"));
39         //等到一個元素從DOM中移除
40         ExpectedConditions.stalenessOf(driver.findElement(By.xpath("//*[@id='kw']")));
41         //判斷某個元素是否被選中,通常用在下拉列表
42         ExpectedConditions.elementToBeSelected(By.xpath("//*[@id='kw']"));
43         //判斷某個元素的選中狀態是否符合預期
44         ExpectedConditions.elementSelectionStateToBe(By.xpath("//*[@id='kw']"), true);
45         //判斷某個元素(已定位)的選中狀態是否符合預期
46         ExpectedConditions.elementSelectionStateToBe(driver.findElement(By.xpath("//*[@id='kw']")), false);
47         //判斷頁面中是否存在alert
48         new WebDriverWait(driver,5).until(ExpectedConditions.alertIsPresent());
49         //--------------------自定義判斷條件-----------------------------
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:ui

1.除了以上內容,selenium還提供了不少預置的判斷方法。spa

2.這些判斷方法,在超出時間限制時就會拋出異常。firefox
