org.openqa.selenium.remote.SessionNotFoundException:Unexpected error launching Internet Explorer. Protected Mode settings are not the same for all zones.

Sometimes when we are trying to load InternetExplorer from WebDriver we will get below error :


org.openqa.selenium.remote.SessionNotFoundException: Unexpected error launching Internet Explorer. Protected Mode settings are not the same for all zones. Enable Protected Mode must be set to the same value (enabled or disabled) for all zones. (WARNING: The server did not provide any stacktrace information)

Command duration or timeout: 1.39 seconds
Build info: version: '2.34.0', revision: '11cd0ef', time: '2013-08-06 17:11:28'
System info: os.name: 'Windows 8', os.arch: 'amd64', os.version: '6.2', java.version: '1.7.0_09'
Driver info: org.openqa.selenium.ie.InternetExplorerDriver 


This error is because of the security settings in IE. There is a permanent fix to this. :P

>> Open IE , then go to Tools>>Security tab .

>>Now either check or uncheck the "Enable Protected Mode" checkbox for all zones i.e Internet , Local internet, Trusted Sites, Restricted Sites.

We are done . Now start running your script , it will go great  without any issues :) 

org.openqa.selenium.WebDriverException: Cannot find firefox binary in PATH. Make sure firefox is installed.

If you running webdriver scripts on Windows 8 then the below error is the first one you will encounter. Atleast it happened for me :) .


org.openqa.selenium.WebDriverException: Cannot find firefox binary in PATH. Make sure firefox is installed. OS appears to be: WIN8
Build info: version: '2.31.0', revision: '1bd294d', time: '2013-02-27 20:53:56'
System info: os.name: 'Windows 8', os.arch: 'amd64', os.version: '6.2', java.version: '1.7.0_09'
Driver info: driver.version: FirefoxDriver


The solution to the above problem is to specify the location of firefox in your script .

System.setProperty("webdriver.firefox.bin", "C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe");

Here is my modified script.And it went through without any errors :)

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class FacebookRegistration {

WebDriver driver;
 
 @BeforeTest
 public void start(){
  System.setProperty("webdriver.firefox.bin", "C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe");
  driver = new FirefoxDriver();
 }
 

 @Test
 public void run(){
  driver.get("http://facebook.com");
 }
}

Permission denied for to get property Window.frameElement Command duration or timeout: 12 milliseconds

I used to get the below error when I try to switch to iframe ( driver.switchTo().frame("iframe_canvas") ).

Seems this issue is happening because of Cross Origin .
Solution to this problem is set the below settings in Firefox Profile.

capability.policy.default.Window.QueryInterface='allAccess'

capability.policy.default.Window.frameElement.get='allAccess'

I changed my code as below. Now it is working fine :)

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;
 
public void IframeTest(){

 WebDriver driver;

@BeforeTest
  public void setUpDriver() {
   FirefoxProfile profile = new FirefoxProfile();
   profile.setPreference("capability.policy.default.Window.QueryInterface", "allAccess");
   profile.setPreference("capability.policy.default.Window.frameElement.get","allAccess");
   driver = new FirefoxDriver(profile);
     }

@Test
 public void delete(){
   Common.FBLogin(fbUsername, fbPassword, driver);
   driver.get("appURL");
   driver.switchTo().defaultContent();
   driver.switchTo().frame("iframe_canvas");  
  }

}

If you ever happened to get the above error then change your Firefox preferences from code :)

TestNG XMLfile preparation and error messages

Here is the sample TestNG file :

It is also important to know about error messages.Sometimes we learn more from errors :)
I have put some of the error messages we get when we go wrong in the above TestNG XML file .

Here are the error codes we will see when we have done any error in the above XML file.

1.If two tests are having the same name then we see below error
Ex :  
<test name="Testing the Google"> 
        <classes>       
        <class name="com.google.UI"/>
     </classes>
  </test> 
  <test name=" Testing the Google "> 
    <classes>       
        <class name="com.google.gmail"/>
     </classes>
  </test>

Missing requirement: Jetty Server Adaptor Plug-in 1.0.4 (org.mortbay.jetty.serveradaptor 1.0.4) requires 'bundle org.eclipse.wst.server.core 0.0.0' but it could not be found

Today I tried to install Jetty plugin in Eclipse using the below URL
http://www.webtide.com/eclipse

But my installation failed with the below error

"Cannot complete the install because one or more required items could not be found.
Software currently installed: Jetty Generic Server Adaptor 1.0.
(org.mortbay.jetty.serveradaptor.feature.group 1.0.4)
Missing requirement: Jetty Server Adaptor Plug-in 1.0.4 
(org.mortbay.jetty.serveradaptor 1.0.4) requires 'bundle org.eclipse.wst.server.core

(org.mortbay.jetty.serveradaptor.feature.group 1.0.4)

Solution to this problem is very simple .

Install Jetty plugin with the below URL
http://download.eclipse.org/jetty/updates/jetty-wtp

Steps :

1. Open Eclipse.
2. click Help -> Install New Software. The Available Software dialog box opens.
3. Add the plugin using below URl  http://download.eclipse.org/jetty/updates/jetty-wtp

Detailed steps with instructions can be found at :

TestNG : The reference to entity "tab" must end with the ';' delimiter.

Today I have faced problem while running the below TestNg XML file .

<!DOCTYPE suite SYSTEM "http://beust.com/testng/testng-1.0.dtd" >
<suite name="testing test suite">
  <parameter name="googlePlayUrl" value="https://play.google.com/store?hl=en&tab=w8"/>
  <test name="checking the Google play">
    <classes>
       <class name="com.google.play.UrlVerification"/>
    </classes>
  </test>
</suite>

When I run the above TestNG XML file I got bellow error

org.testng.TestNGException: org.xml.sax.SAXParseException: The reference to entity "tab" must end with the ';' delimiter.
at org.testng.TestNG.initializeSuitesAndJarFile(TestNG.java:335)
at org.testng.remote.RemoteTestNG.run(RemoteTestNG.java:88)
at org.testng.remote.RemoteTestNG.initAndRun(RemoteTestNG.java:202)
at org.testng.remote.RemoteTestNG.main(RemoteTestNG.java:173)
Caused by: org.xml.sax.SAXParseException: The reference to entity "tab" must end with the ';' delimiter.

Solution to the above problem is very simple. Replace the "&" symbol with "&amp;"

I have changed my XML file like below and it was successed.

<!DOCTYPE suite SYSTEM "http://beust.com/testng/testng-1.0.dtd" >
<suite name="testing test suite">
  <parameter name="googlePlayUrl" value="https://play.google.com/store?hl=en&amp;tab=w8"/>
  <test name="checking the Google play">
    <classes>
       <class name="com.google.play.UrlVerification"/>
    </classes>
  </test>
</suite>

So we have removed Android jars(android_webdriver_library-srcs.jar ,android_webdriver_library ) from our project Build path , then all the scripts started working fine.

We are still searching why this conflict happened and how to overcome this :)

Today I tried Install Maven plugin from
http://q4e.googlecode.com/svn/trunk/updatesite-iam/

I got so many errors which reads

Eclipse IAM Buckminster Integration 0.10.0.201003091836 (org.eclipse.iam.feature.buckminster.feature.group 0.10.0.201003091836)Missing requirement: Eclipse IAM Buckminster Integration 0.10.0.201003091836 (org.eclipse.iam.feature.buckminster.feature.group 0.10.0.201003091836) requires 'org.eclipse.buckminster.core [1.1.0,2.0.0)' but it could not be found


If you ever get any error messages like above while installing Maven plugin OR using Maven plugin then try to reinstall Maven plugin again from the below URL.

http://download.eclipse.org/technology/m2e/releases

Goto
Eclipse >>Help>>Install New Software>>

and enter the URl to install Maven Plugin.
