Question

未使用selenium webdriver加载表内容。它仅显示表格的标题，但不显示内容。

我已在我的应用程序中成功登录，但在主屏幕上有一个列出某个项目的表，而使用selenium则不会在表中加载内容。

硒罐： 2.53
Mozilla Firefox版本： 46.0

使用谷歌浏览器浏览器，但它也没有用。

当我关闭浏览器（打开了哪个selenium）并手动重新打开它时，它可以正常工作。但是当selenium打开并转到主页时，表数据不会加载。

 <div class="project-list-bg" _ngcontent-c1="">

------------ Selenium Code --------------------------------- -

package projectListingScreen;

import org.testng.annotations.Test;

import ObjectRepository.HomescreenObject;
import ObjectRepository.PageObject;
import loginScreen.LoginPage;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.PageFactory;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.BeforeTest;

public class HomeScreen extends LoginPage {

    public WebDriver driver;

  @Test
  public void f() {

         WebDriverWait wait=new WebDriverWait(driver, 20);
          WebElement addprojectbutton;
          addprojectbutton = wait.until(ExpectedConditions.elementToBeClickable(By.xpath( "html/body/app-root/app-home/div/div/main/div[3]/div[1]/a/button")));
          addprojectbutton.click();

  }

我必须单击此<button>元素，但如果表格（您可以在评论中找到的表格的HTML）未正确加载，则此按钮向上移动，selenium无法找到此按钮，作为回报给出空指针异常。

Answer 1

要点击此<button>，文字为添加项目，因为 AUT 包含 Angular 元素，您必须诱导< em> WebDriverWait ，元素可点击，您可以使用以下代码行：

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//button[@class='btn next-btn p-btn'][normalize-space()='Add Project']"))).click();

无法使用selenium webdriver
