如果我期望硒不是在硒中工作

Question

我的代码无法正常使用if else语句，默认情况下，即使“ if语句”错误，它也会检查if条件，并抛出错误：

org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":".//span[contains(text(),'Dashboard')]"}

它不检查else if语句。

我的代码

driver.findElement(By.name("userName")).sendKeys(user);
driver.findElement(By.name("password")).sendKeys(pass);
driver.findElement(By.name("submit")).click();

Thread.sleep(3000);
//WebDriverWait wait= new WebDriverWait(driver,60);
WebElement success = driver.findElement(By.xpath(".//span[contains(text(),'Dashboard')]"));

WebElement failure = driver.findElement(By.xpath(".//div[contains(text(),'Your login attempt was not successful due to Invalid credentials!!')]"));

if(success!=null && success.getText().matches("Dashboard")) {
    System.out.println("Able to login with this credentials "+user+" "+pass);
}
else if(failure!=null && failure.getText().matches("Your login attempt was not successful due to Invalid credentials!!")) {
    System.out.println("Unable to login with this credentials "+user+" "+pass);
}

一些断点可以解决此问题。问题不在于If / Else语句，而是此行：

WebElement success=driver.findElement(By.xpath(".//span[contains(text(),'Dashboard')]"));

如果您为findElement读了documentation，则在找不到要搜索的元素时会引发错误。这是您面临的错误，而不是if / else语句。一种可能的解决方案是在findElement的周围插入try / catch，并在引发错误时将成功值分配为null。
