Selen Java WebDriver, NoSuchElementException: kein solches Element: Kann Element finden: { "Methode": "Klassenname", "Selektor": "btn_content"}

Question

Ich verfolge die 2 Tutorial Websites unter:

• https://www.guru99.com/installing-selenium-webdriver.html
• http://www.softwaretestingstudio.com/click-button-selenium-webdriver-java/

ich versuche, eine Login-Seite, zu automatisieren, aber immer auf der Schaltfläche „Weiter“ steckte auf die nächste Seite zu gelangen.

Ich verwende:

• Chrome Browser-Version 61.0.3163.100
• Eclipse-Java Oxygen
• JDK 9
• Selen-Java-Client-Treiber 3.6.0

Unten ist ein Ausschnitt des HTML für die Schaltfläche "Weiter".

<button type="submit" class="btn btn--block btn--raised primary" white--text="" style="position: relative;"> 
 
<div class="btn__content">Next</div> 
 
</button>

package newpackage; 

import java.util.concurrent.TimeUnit; 
import org.openqa.selenium.By; 
import org.openqa.selenium.WebElement; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.chrome.ChromeDriver; 

public class T2 { 
public static void main(String[] args) { 
    System.setProperty("webdriver.chrome.driver","C:\\Users\\struong\\chromedriver_win32\\chromedriver.exe"); 
    WebDriver driver = new ChromeDriver(); 
    driver.manage().timeouts().implicitlyWait(20,TimeUnit.SECONDS); 

    String baseUrl = "https://vertical.vappcenter.com/login"; 
    driver.get(baseUrl); 

    // Get the WebElement corresponding to the Email Address(TextField)  
    WebElement Email = driver.findElement(By.id("email"));           
    // Type in an email address 
    Email.sendKeys("struong@vertical.com");           
    // Find the Next button and click it   
    WebElement bNext = driver.findElement(By.className("btn_content")); 
    // Using click method to click Next  
    bNext.click(); 

    } 
}  

ich Fehler:

Answer 1

Als Fehler vorschlagen, Selen nicht in der Lage ist Element zu finden. Sie können Elemente mit dem folgenden Text suchen:

By.XPath("//button[.= 'Next']")
