element not interactable exception in selenium web automation

问题

In the below code i cannot send password keys in the password field, i tried clicking the field, clearing the field and sending the keys. But now working in any of the method. But its working if i debug and test

  public class TestMail {
   protected static WebDriver driver;

   protected static String result;

   @BeforeClass

   public static void setup()  {
              System.setProperty("webdriver.gecko.driver","D:\\geckodriver.exe");

   driver = new FirefoxDriver();

   driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);

  }

   @Test

 void Testcase1() {

   driver.get("http://mail.google.com");

   WebElement loginfield = driver.findElement(By.name("Email"));
   if(loginfield.isDisplayed()){
       loginfield.sendKeys("ragesh@gmail.in");
   }
   else{
  WebElement newloginfield = driver.findElemnt(By.cssSelector("#identifierId"));                                      
       newloginfield.sendKeys("ragesh@gmail.in");
      // System.out.println("This is new login");
   }


    driver.findElement(By.name("signIn")).click();

  // driver.findElement(By.cssSelector(".RveJvd")).click();

   driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
 // WebElement pwd = driver.findElement(By.name("Passwd"));
  WebElement pwd = driver.findElement(By.cssSelector("#Passwd"));

  pwd.click();
  pwd.clear();
 // pwd.sendKeys("123");
 if(pwd.isEnabled()){
     pwd.sendKeys("123");
 }
 else{
     System.out.println("Not Enabled");
 }

回答1:

Try setting an implicit wait of maybe 10 seconds.

gmail.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

Or set an explicit wait. An explicit waits is code you define to wait for a certain condition to occur before proceeding further in the code. In your case, it is the visibility of the password input field. (Thanks to ainlolcat's comment)

WebDriver gmail= new ChromeDriver();
gmail.get("https://www.gmail.co.in"); 
gmail.findElement(By.id("Email")).sendKeys("abcd");
gmail.findElement(By.id("next")).click();
WebDriverWait wait = new WebDriverWait(gmail, 10);
WebElement element = wait.until(
ExpectedConditions.visibilityOfElementLocated(By.id("Passwd")));
gmail.findElement(By.id("Passwd")).sendKeys("xyz");

Explanation: The reason selenium can't find the element is because the id of the password input field is initially Passwd-hidden. After you click on the "Next" button, Google first verifies the email address entered and then shows the password input field (by changing the id from Passwd-hidden to Passwd). So, when the password field is still hidden (i.e. Google is still verifying the email id), your webdriver starts searching for the password input field with id Passwd which is still hidden. And hence, an exception is thrown.

Please try selecting the password field like this.

    WebDriverWait wait = new WebDriverWait(driver, 10);
    WebElement passwordElement = wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector("#Passwd")));
    passwordElement.click();
  passwordElement.clear();
     passwordElement.sendKeys("123");

I had the same problem and then figured out the cause. I was trying to type in a span tag instead of an input tag. My XPath was written with a span tag, which was a wrong thing to do. I reviewed the Html for the element and found the problem. All I then did was to find the input tag which happens to be a child element. You can only type in an input field if your XPath is created with an input tagname

Instead of just constant wait it's much better to use timeout for needed action so it will automatically execute once element become intractable. I'm using free TestProject automation SDK to make such things easier. Here's short example of how it looks like in the code:

by = By.xpath("//input[@class='btn btn-primary search_button last ']");
driver.testproject().clickIfVisible(by,10);

where 10 is timeout for this action. There are also different ways to implement it using isDisplayed,isClickable etc...
