Java selenium questions

What I'm wanting to do is read each line and make it input into email, it does that once, when I try to "refresh" the page to clear the text boxs I get an error.

try (BufferedReader br = new BufferedReader(new FileReader("emails.txt"))) {
String line;
while ((line = br.readLine()) != null) {
driver.get("https://signup.live.com/signup?wa=wsignin1.0&rpsnv=12&ct=1465840004&rver=6.7.6643.0&wp=&wreply=https%3a%2f%2fwww.msn.com%2fen-us%2fhomepage%2fSecure%2fPassport%3fru%3dhttp%253a%252f%252fwww.msn.com%252f%253focid%253dmailsignout%2526pfr%253d1&id=1184&pcexp=True&bk=1465840005&uiflavor=web&uaid=dc151162984741948b8371ce3e0c865e&mkt=EN-US&lc=1033&lic=1");
Thread.sleep(650);
Email.sendKeys(line);
Refresher.click();
Thread.sleep(650);
if (TakenErrorMsg.isDisplayed()){
System.out.println(line + " is taken!");

}else{
System.out.println(line + " is not taken!");
}
}
} catch (IOException e) {
e.printStackTrace();
}


This is the error, i'm pretty new so if anyone could show me how to "read" this it would be very helpful.

Answer

If you read the exception log, the first line tells you what went wrong:

Exception in thread "AWT-EventQueue-0" org.openqa.selenium.StaleElementReferenceException: stale element reference: element is not attached to the page document

This is telling you that selenium threw a StaleElementReferenceException, if you google it, you will get to this selenium documentation page (link). Which basically it explains you that the element you are trying to reach through selenium is not longer in the DOM.

This is happening because you are reloading the page several times, you would need to refresh the instances of your elements on each page load, the elements that you need to reload the reference is:

  • Email
  • Refresher
  • TakenErrorMsg
