Question

LoginPage.java

   public LoginPage(WebDriver driver){
     //initialize elements
     PageFactory.initElements(driver, this);
   }

   public void set_email(String useremail){
       email.clear();
       email.sendKeys(useremail);
   }

   public void set_password(String userpassword){
        password.clear();
        password.sendKeys(userpassword);
   }

   public void click_button(){
        button.submit();
   }

   public void equal_titles(String actualTitle,String expectedTitle){
        Assert.assertEquals(actualTitle,expectedTitle);
   }

   public void set_reset_email(String resetemail){
        reset_psw_email.clear();
        reset_psw_email.sendKeys(resetemail);
   }

   public void click_reset_button(){
        reset_button.submit();
   }

TestingLogin.java

   @BeforeTest
   public void setup(){
       System.setProperty("webdriver.gecko.driver", "\\GeckoDriver\\geckodriver.exe");
       driver=new FirefoxDriver();
       driver.manage().window().maximize();
       driver.get("https://test.admin.placer.life/login");
   }

   @Test(priority=9)
   public void reset_psw(){
       LoginPage login=new LoginPage(driver);
       driver.findElement(By.xpath("//*[@id='app']/div/div[2]/a")).click();     
       WebDriverWait wait = new WebDriverWait(driver, 5);
    wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id='app']/div/div[2]/form/div[3]/div[2]/button[contains(text(),'Send Password Reset Link')]")));
       String expectedTitle = "Placer Admin - Password recovery";
       String actualTitle = driver.getTitle();
       login.equal_titles(actualTitle, expectedTitle);
   }

   @Test(priority=8)
   public void reset_email(){
       LoginPage login=new LoginPage(driver);
       driver.findElement(By.xpath("//*[@id='app']/div/div[2]/a")).click();
       WebDriverWait wait = new WebDriverWait(driver, 10);
    wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id='app']/div/div[2]/form/div[3]/div[2]/button[contains(text(),'Send Password Reset Link')]")));
       login.set_reset_email("");
       login.click_reset_button();  
       WebDriverWait wait_reset_psw = new WebDriverWait(driver, 10);
    wait_reset_psw.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id='app']/div/div[2]/form/div[2]/span[2]")));
    Assert.assertEquals(driver.findElement(By.xpath("//*[@id='app']/div/div[2]/form/div[2]/span[2]")).getText(),"The email field is required.");
      // driver.navigate().refresh();
   }

   @AfterTest
   public void close(){
       driver.close();
   }

结果

PASSED：reset_email

失败：reset_psw

org.openqa.selenium.TimeoutException：预期的条件失败：等待By.xpath定位的元素的可见性：// * [@ id =＆＃39; app＆＃39;] / div / div [2] / form / div [3] / div [2] / button [包含（文本（），＆＃39;发送密码重置链接＆＃39;）]（尝试5秒钟，间隔500 MILLISECONDS）

运行代码时发生此错误。但是当我评论其中一个（reset_email或reset_psw）时，另一个将成功通过而没有任何错误。我可以知道解决方案吗？需要对此代码进行哪些修改？

请帮忙，非常感谢你

它看起来像它所做的那样。您是否尝试增加WebDriverWait应该等待的时间？

public void reset_psw()
{
LoginPage login=new LoginPage(driver);
driver.findElement(By.xpath("//*[@id='app']/div/div[2]/a")).click();        
WebDriverWait wait = new WebDriverWait(driver, 60); // <-- Here    
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id='app']/div/div[2]/form/div[3]/div[2]/button[contains(text(),'Send Password Reset Link')]")));
String expectedTitle = "Placer Admin - Password recovery";
String actualTitle = driver.getTitle();
login.equal_titles(actualTitle, expectedTitle);
}

public void reset_email()
{
   LoginPage login=new LoginPage(driver);
   driver.findElement(By.xpath("//*[@id='app']/div/div[2]/a")).click();
   WebDriverWait wait = new WebDriverWait(driver, 60);
   wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id='app']/div/div[2]/form/div[3]/div[2]/button[contains(text(),'Send Password Reset Link')]")));
   login.set_reset_email("");
   login.click_reset_button();  
   WebDriverWait wait_reset_psw = new WebDriverWait(driver, 60);

   wait_reset_psw.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id='app']/div/div[2]/form/div[2]/span[2]")));
   Assert.assertEquals(driver.findElement(By.xpath("//*[@id='app']/div/div[2]/form/div[2]/span[2]")).getText(),"The email field is required.");
  // driver.navigate().refresh();
}

这会增加超时。

根据问题和代码试用中的结果部分， Testcase reset_email() PASSED 和 Testcase reset_psw() FAILED 为：

TimeoutException: Expected condition failed: waiting for visibility of element

似乎在你的@Test步骤中，代码块几乎相似。带有（priority = 8）的 @Test 首先在其中调用函数login.click_reset_button();，该函数调用reset_button.submit();并在您重定向到新页面断言文本电子邮件字段是必需的。。

现在，值得一提的是，当您调用click()或submit()并且用户被重定向到新页面时，HTML DOM会发生变化。随着 DOM树的更改，部分/所有元素可能会添加 / 已删除 / 已修改。因此，当您使用@Test方法调用 ExpectedConditions 时，您的下一个visibilityOfElementLocated()因为之前的元素未附加到 DOM {{3} }或NoSuchElementException被引发，最终导致StaleElementReferenceException
