硒網格測試情況下,無頭的瀏覽器模式下模擬瀏覽器測試案例失敗 - selemium電網

正常的瀏覽器模式 [試車成功]

  • 硒獨立服務器失敗:3.0.1
  • 火狐:38.0.1
  • IP:192.168.1.40

無頭瀏覽器模式 [測試失敗]

  • 硒獨立服務器:3.0.1
  • 火狐:38.0
  • IP:172.18.0.60

我運行模擬瀏覽器像下面

xvfb的-運行java -Dwebdriver.firefox.marionette = 「/ TMP/geckodriver」 -Dwebdriver.firefo x.bin = 「/ tmp目錄/火狐/火狐」 的罐子硒的服務器獨立-3.0.1.jar -role webdriver的-hub http://192.168.1.106:4444/grid/register -port 5566 -host 172.18.0.60

測試用例代碼:

package example; 

import org.junit.Assert; 
import org.openqa.selenium.*; 
import org.openqa.selenium.remote.RemoteWebDriver;

import java.net.MalformedURLException; 

public class NewTest 
{ 
    public WebDriver driver; 
    public String URL, Node; 
    private JavascriptExecutor jse; 
    private String baseUrl; 

    protected ThreadLocal<RemoteWebDriver> threadDriver = null; 

    @Parameters({"browser","url"}) 
    @BeforeTest 
    public void launchapp(String browser,String url) throws MalformedURLException 
    { 
     baseUrl = "http://myhost"; 

     if (browser.equalsIgnoreCase("firefox")) 
     { 
     System.out.println(" Executing on FireFox"); 
     String Node = url; 
     DesiredCapabilities cap = DesiredCapabilities.firefox(); 
     cap.setBrowserName("firefox"); 

     driver = new RemoteWebDriver(new URL(Node), cap);   
     // Puts an Implicit wait, Will wait for 10 seconds before throwing exception 
     driver.manage().timeouts().implicitlyWait(50, TimeUnit.SECONDS); 

     // Launch website 
     driver.navigate().to(baseUrl); 
     driver.manage().window().maximize(); 
     }   
     else 
     { 
     throw new IllegalArgumentException("The Browser Type is Undefined"); 
     } 

     jse = (JavascriptExecutor)driver; 
    } 

    @Test 
    public void functionalityTest() throws InterruptedException 
    {  
     driver.findElement(By.linkText("Sign In")).click(); 
     driver.findElement(By.id("email")).clear(); 
     driver.findElement(By.id("email")).sendKeys("[email protected]"); 
     driver.findElement(By.id("pass")).clear(); 
     driver.findElement(By.id("pass")).sendKeys("xxxxxx"); 
     driver.findElement(By.id("send2")).click();  
     jse.executeScript("scroll(0, 250);"); 
     driver.findElement(By.cssSelector(".customerlink a")).click(); 
     Thread.sleep(1000); 
     driver.findElement(By.linkText("My Account")).click();  
     Thread.sleep(2000); 
     jse.executeScript("scroll(0, 250);"); 
     Thread.sleep(1000); 
     jse.executeScript("scroll(0, -250);"); 
     Thread.sleep(2000); 
     driver.findElement(By.cssSelector(".customerlink a")).click(); 
     Thread.sleep(1000); 
     driver.findElement(By.linkText("Sign Out")).click(); 
     Thread.sleep(2000); 
    } 

    @AfterTest 
    public void closeBrowser() 
    { 
     driver.quit(); 
    } 
}

錯誤狀態顯然無法定位元素,但它是如何在正常模式下工作的?

使用無頭瀏覽器模式的代碼有沒有限制?

我可以知道在上面的哪裏,你正在使用「無頭瀏覽器」的概念?據我所知,無頭瀏覽器是在「HtmlUnitDriver」中實現的,可能是NodeJSDriver(這個我還沒試過)。我在這裏錯過了任何概念嗎? – Uday

哥們,我太新了!我相信無頭模式是在沒有瀏覽器UI的情況下運行硒測試。我的瀏覽器運行在xvfb而不是UI模式,所以我相信它是無頭模式。爲您的簡單參考http://agiletesting.blogspot.in/2016/01/running-selenium-webdriver-tests-using.html –

看起來像這樣xvfb在Linux/Ubuntu環境中工作,而不是在Windows上。發現xnest也適用於Linux/Ubuntu env。發現這個鏈接'http://stackoverflow.com/questions/944086/is-there-anything-like-xvfb-or-xnest-for-windows'的Windows版本。 – Uday

最後發現,無頭的瀏覽器不考慮driver.manage().window().maximize();所以通過xvfb的運行命令設置屏幕尺寸

-s 「-screen 0,1920x1080x24」

實施例:

xvfb-run -s「-screen 0,1920x1080x24」java -Dwebdriver.firefox.marionette =「/ tmp/geckodriver」-Dwebdriver.firefox.bin =「/ tmp/firefox/firefox」-jar selenium-server -s tandalone-3.0.1.jar -role webdriver的-hub http://192.168.1.106:4444/grid/register -port 5566 -host 172.18.0.60

信息:我使用的引導,從而可見元素,以根據屏幕大小而改變。所以它會拋出元素沒有找到exeception
