如何使用氦氣檢查啓用和禁用按鈕？

Question

連接按鈕的代碼是：

<div style="position: absolute; right: 0; top: 0;"> 
<button class="prev btn btn-warning disabled" style="padding: 4px 8px;"> 
<i class="fa fa-chevron-left" style="margin: 0"/> 
</button> 
<button class="next btn btn-warning" style="padding: 4px 8px;"> 
<i class="fa fa-chevron-right" style="margin: 0"/> 
</button> 
</div> 

我如何檢查我想哪一個是使用氦氣 使下面的代碼

 click("Home"); 

     if(Button(">").isEnabled()){ 
     click($("html/body/div[6]/div/h3/div/button[2]")); 
     } 

     else{ 
     click($("html/body/div[6]/div/h3/div/button[1]")); 
     } 

但有以下錯誤

Exception in thread "main" org.openqa.selenium.NoSuchElementException: Cannot find element ButtonImpl(">"). For documentation on this error, please visit: http://seleniumhq.org/exceptions/no_such_element.html Build info: version: '2.45.0', revision: '5017cb8e7ca8e37638dc3091b2440b90a1d8686f', time: '2015-02-27 09:10:26' System info: host: 'Keya-PC', ip: '172.16.0.144', os.name: 'Windows 7', os.arch: 'amd64', os.version: '6.1', java.version: '1.8.0_25' Driver info: driver.version: unknown at com.heliumhq.api_impl.GUIElementImpl.perform(GUIElementImpl.java:107) at com.heliumhq.api_impl.GUIElementImpl.bindToFirstOccurrence(GUIElementImpl.java:94) at com.heliumhq.api_impl.GUIElementImpl.getFirstOccurrence(GUIElementImpl.java:89) at com.heliumhq.api_impl.ButtonImpl.isEnabled(ButtonImpl.java:26) at com.heliumhq.API$Button.isEnabled(API.java:1276) at searchHomePage.search(searchHomePage.java:30) at mainClass.main(mainClass.java:19)

將不勝感激的幫助。

Answer 1

錯誤：找不到元素ButtonImpl（ 「>」）

我們需要檢查之類的代碼存在（分組BTN BTN-警告關閉或下一個BTN BTN-警告）。

元素「>」不在頁面上是圖片。

UPD：

if (driver.findElements(By.xpath("someXpath")).size == 0)

或

$(By.xpath("someXpath")).shouldNotBe(visible);

代碼Java中：

public static boolean isElementPresent(By by) {
 

try { 
    driver.findElement(by); 
    return true; 
} catch (NoSuchElementException e) { 
    return false; 
} 

}
