How to use getErrorType method of org.openqa.selenium.grid.graphql.SessionNotFoundException class

The fact that PhantomJS keeps sessions between tests is a known problem in GhostDriver, the Selenium Webdriver implementation in PhantomJS.

I suppose that this problem will be fixed with the PhantomJS 2 release. The bug is already fixed in GhostDriver 1.1.1, but there is no PhantomJS version which includes this GhostDriver version.

This is just a version mismatch. You have compiled your code using java version 9 and your current JRE is version 8. Try upgrading your JRE to 9.

49 = Java 5
50 = Java 6
51 = Java 7
52 = Java 8
53 = Java 9
54 = Java 10
55 = Java 11
56 = Java 12
57 = Java 13
58 = Java 14
59 = Java 15
60 = Java 16
61 = Java 17
62 = Java 18
63 = Java 19

The best way for you is to take java (which is officially deprecated and it suggests you use openjdk image) and install node in it.

So, start with

FROM openjdk:latest

This will use the latest openjdk image, which is 8u151 at this time. Then install node and other dependencies you might need:

RUN apt-get install -y curl \
  && curl -sL https://deb.nodesource.com/setup_9.x | bash - \
  && apt-get install -y nodejs \
  && curl -L https://www.npmjs.com/install.sh | sh

You might want to install things like grunt afterwards, so this might come in handy as well.

RUN npm install -g grunt grunt-cli

In total you will get the following Dockerfile:

FROM openjdk:latest

RUN apt-get install -y curl \
  && curl -sL https://deb.nodesource.com/setup_9.x | bash - \
  && apt-get install -y nodejs \
  && curl -L https://www.npmjs.com/install.sh | sh \
RUN npm install -g grunt grunt-cli

You may clone the Dockerfile from my gitlab repo here

There is a minor bug in your code block. When you are using TestNG and writing methods within @Test annotation, we should define the methods with proper return types. I have used your own code and simply added the return type as void as follows:

import org.testng.Assert;
import org.testng.annotations.Test;

public class Q45191867_Assert_Pass_Suite 
{

    @Test   
    public void TC002_CheckAssert() 
    {
        System.out.println("ajkcbh");
        try
        {
            Assert.assertEquals("Pass", "Pass");
        }
        catch(Exception e)
        {
            System.out.println("Exception:"+e.getLocalizedMessage());
        }
    }
}

The code block executes successfully when executed as TestNG Test.

I have executed the code block converting into TestNG with the following testng.xml as follows:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite">
  <test name="Test">
    <classes>
      <class name="demo.Q45191867_Assert_Pass_Suite"/>
    </classes>
  </test> <!-- Test -->
</suite> <!-- Suite -->

I have executed this code block again as TestNG Suite. In this case as well the output on the console was:

[TestNG] Running:
  C:\Users\AtechM_03\LearnAutmation\LearnAutomationTestNG\testng.xml

ajkcbh

If anyone actually knew a general and always-applicable answer, it would have been implemented everywhere ages ago and would make our lives SO much easier.

There are many things you can do, but every single one of them has a problem:

1. As Ashwin Prabhu said, if you know the script well, you can observe its behaviour and track some of its variables on window or document etc. This solution, however, is not for everyone and can be used only by you and only on a limited set of pages.

2. Your solution by observing the HTML code and whether it has or hasn't been changed for some time is not bad (also, there is a method to get the original and not-edited HTML directly by WebDriver), but:

   • It takes a long time to actually assert a page and could prolong the test significantly.
   • You never know what the right interval is. The script might be downloading something big that takes more than 500 ms. There are several scripts on our company's internal page that take several seconds in IE. Your computer may be temporarily short on resources - say that an antivirus will make your CPU work fully, then 500 ms may be too short even for a noncomplex scripts.
   • Some scripts are never done. They call themselves with some delay (setTimeout()) and work again and again and could possibly change the HTML every time they run. Seriously, every "Web 2.0" page does it. Even Stack Overflow. You could overwrite the most common methods used and consider the scripts that use them as completed, but ... you can't be sure.
   • What if the script does something other than changing the HTML? It could do thousands of things, not just some innerHTML fun.

3. There are tools to help you on this. Namely Progress Listeners together with nsIWebProgressListener and some others. The browser support for this, however, is horrible. Firefox began to try to support it from FF4 onwards (still evolving), IE has basic support in IE9.

And I guess I could come up with another flawed solution soon. The fact is - there's no definite answer on when to say "now the page is complete" because of the everlasting scripts doing their work. Pick the one that serves you best, but beware of its shortcomings.

Page is not menu. Page has menu. We can extend only if it IS A relationship. Otherwise go with composition over inheritance principle.

I would suggest you to go with Page Fragments for better reusability.

That is, you create reusable components called 'Page Fragments' as shown here and use it in the Page Objects.

Just for anyone else who's looking for an answer in Ruby, Python, and C# bindings (Selenium 2.33.0).

Note that the actual keys to send depend on your OS. For example, Mac uses CMD + T, instead of Ctrl + T.

Ruby

require 'selenium-webdriver'

driver = Selenium::WebDriver.for :firefox
driver.get('http://stackoverflow.com/')

body = driver.find_element(:tag_name => 'body')
body.send_keys(:control, 't')

driver.quit

Python

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://stackoverflow.com/")

body = driver.find_element_by_tag_name("body")
body.send_keys(Keys.CONTROL + 't')

driver.close()

C#

using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;

namespace StackOverflowTests {

    class OpenNewTab {

        static void Main(string[] args) {

            IWebDriver driver = new FirefoxDriver();
            driver.Navigate().GoToUrl("http://stackoverflow.com/");

            IWebElement body = driver.FindElement(By.TagName("body"));
            body.SendKeys(Keys.Control + 't');

            driver.Quit();
        }
    }
}

The link https://code.google.com/p/chromedriver/issues/detail?id=187 mentions that firefox browser has support for non-BMP characters as well.

I tried using firefox driver and Firefox browser (version 31) and it worked. Right now this is the workaround, instead of using chrome driver to use firefox driver.

For anyone interested, I solved this in the following ways:

1) I was originally testing this on OSX with Firefox 17 and Selenium 2.28/29, but figured out it only works (at least for me) on Windows with Firefox 18 and Selenium 2.29

2) interacting with SVGs with the standard:

driver.findElement(By.xpath(YOUR XPATH)).click();

doesn't work. You need to use Actions.

3) to interact with SVG objects, the following XPath works:

"/*[name()='svg']/*[name()='SVG OBJECT']";

The SVG object being anything under the SVG element (e.g. circle, rect, text, etc).

An example of clicking an SVG object:

WebElement svgObject = driver.findElement(By.xpath(YOUR XPATH));
Actions builder = new Actions(driver);
builder.click(svgObject).build().perform();

Note: you need to call the path inside the click() function; using:

moveToElement(YOUR XPATH).click().build().perform();

doesn't work.
