[solved]java.lang.IllegalStateException – Driver not executable on MAC

total-qa September 9, 2018 7 Comments

In this tutorial we will discuss how to solve the java.lang.IllegalStateException on MAC during the execution of tests on Chrome Browser.
Before getting into point, we will discuss about File Permissions on Unix platform. Each and every file in Unix has following attributes:

Owner: Owner of the file
Group: User belongs to a particular Group
Other: Other users

To view permissions of any file on unix use the following command:
total-qa$ ls -l chromedriver -rw-r--r-- 1 25399 25399 chromedriver

Changing Permissions

We can modify the permissions of a file by providing following Access:

Read
Write
Execute

To provide all the read,write and execute permissions for all the attributes Group,Owner and Others for a file in Unix use the following command in the terminal as mentioned below:

total-qa$ chmod 777 chromedriver Owner :4 (read) + 2 (write) + 1 (execute) = 7 rwx Group :4 (read) + 2 (write) + 1 (execute) = 7 rwx Others :4 (read) + 2 (write) + 1 (execute) = 7 rwx

We can even update the permissions of the File in Eclipse directly as well.

1. Right Click on the project and select the Properties.

chromedriver properties on MAC

2. Select all the Read,Write and Execute permissions for Owner,Group and Others.

chmod:777 – Read,Write,Execute permissions for Owner,Group and Other Attributes

Conclusion:

Modifying the permissions of the file executes the chromedriver and launches the Chrome Browser successfully.

java-semicolon after for loop,while loop,if statement

total-qa September 6, 2018 2 Comments

In this tutorial we will discuss about the problem by adding the semicolon after for-loop,while-loop and if-statement. This concept is very important to know from Selenium WebDriver perspective as well. We mainly use for-loop for iterating the List of WebElements.
Also, one important key-note here is adding semicolon does not throw any compilation error in Eclipse.
So, it would be difficult to understand the reason why the code is not working as expected.
Else we can depend on the static code checking tools such as following which helps in identifying those issues.

java-semicolon after for loop,while loop,if statement

Adding Semicolon for if-Statement:

int i = 1; if(i==2);//condition is false { System.out.println("if-statement");//Empty Statement will be executed }

Output:

if-statement

Conclusion:

if(i==2); Adding semi-colon for if-statement the line is ended.
The code in the curly braces executes irrespective of the condition is true or false.

Adding Semicolon for for-loop:

for(int i=0;i>10;i++);//condition is false { System.out.println("in for-loop");//Empty Statement will be executed }

Output:

in for-loop

Conclusion:

for(int i=0;i>10;i++); Adding semi-colon for-loop the line is ended.
The code in the curly braces executes irrespective of the condition is true or false.

Adding Semicolon for while-loop:

int j = 1; while(j>10); { System.out.println("in while-loop");//Empty statement will be executed. }

Output:

in while-loop

Conclusion:

while(j>10); Adding semi-colon for while-loop ends the line.
The code in the curly braces executes irrespective of the condition is true or false.

Therefore adding the semicolon executes the empty statements without any errors.

Highlighting the Empty Statements with Errors in Eclipse

Enable Empty Statement

Enabling Empty Statements shows the following Errors during compilation in Eclipse:

Empty Statement Errors

Automating SVG and Interactive Charts in Selenium-JavascriptExecutor

total-qa September 3, 2018 3 Comments

In this tutorial we will discuss about automating the Interactive Charts and SVG [Scalable Vector Graphics] in Selenium.

To automate these Interactive Charts, Selenium Locators such as Xpath and Css-Selector are not helpful. We should depend on an Interface called JavascriptExecutor to identify the SVG and read the values available in these charts.

Javascript Commands:

Reading Attributes of SVG graph[Scalable Vector Graphics]
document.getElementsByTagName('svg')[0].getAttribute('class')

Scalable Vector Graphics – SVG

Reading Data from the Chart
document.getElementsByTagName('path')[0].getAttribute('d')

Interactive Chart-Line Chart

Executing the Javascript Commands in Selenium WebDriver

import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class HandlingInteractiveCharts{

	public static void main(String[] args) {
		
		WebDriver driver = new FirefoxDriver();
	 	driver.get("https://www.highcharts.com/demo/line-basic");
	 	
	 	//JavascriptExecutor is an interface
	 	JavascriptExecutor jse = (JavascriptExecutor) driver;
	 	Object o = jse.executeScript("return document.getElementsByTagName('path')[0].getAttribute('d')");
	 	String s = (String) o;
	 	System.out.println(s);
	 	
	 	
	 	o = jse.executeScript("return document.title");
	    s=(String) o;
	    System.out.println(s);
	}
}

import org.openqa.selenium.JavascriptExecutor;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;

public class HandlingInteractiveCharts{

public static void main(String[] args) {

WebDriver driver = new FirefoxDriver();

driver.get("https://www.highcharts.com/demo/line-basic");

//JavascriptExecutor is an interface

JavascriptExecutor jse = (JavascriptExecutor) driver;

Object o = jse.executeScript("return document.getElementsByTagName('path')[0].getAttribute('d')");

String s = (String) o;

System.out.println(s);

o = jse.executeScript("return document.title");

s=(String) o;

System.out.println(s);

}

Output:

M 84.5 73 L 84.5 359 Basic line | Highcharts

DevOps Tutorial-2 Resolve merge conflicts in Git and GitHub

total-qa August 30, 2018 No Comments

In this tutorial we will learn about resolving the merge conflicts in Git and Github. Git can often resolve differences between merged branches. Usually, the changes are on different lines, or even in different files, which makes the merge simple for computers to understand.

However, sometimes there are competing changes that Git needs your help with to decide which changes to incorporate in the final merge. Often, merge conflicts happen when people make different changes to the same line of the same file, or when one person edits a file and another person deletes the same file. You must resolve the conflict before you can merge the branches.

Lets discuss this scenario in detail:

1. Generally developers or testers create a new branch and modify the HelloWorld.java in there own branch Fix_Bug01.

Creating a new branch for safely experimenting the changes

Adding a new line

2. During the same time if another team member modify the same file and same lines in the master branch in the Github Repository.

Updating the File in Github master branch

Committing the changes

3. In Local Repository if the master branch is refreshed from Global Repository and try to merge these changes in the branch Fix_Bug01 which introduces the merge conflicts.

Refresh the Master

Conflicts due to changes in the same file and same line

4. Fixing the merge Conflicts by ignoring the lines which are not required.

Merge Conflicts

Deleted the unnecessary lines of code

5. Execute the below commands in the Git bash to resolve the merge conflict.
git status

git add

git commit -m "Commit Message"

Fixing the merge conflicts

Conclusion:

In this example we have learnt how to resolve the merge conflicts in Github and Git.

Selenium WebDriver Tutorial WebElement Methods

total-qa August 30, 2018 No Comments

In this example we will discuss about the WebElement Methods available in Selenium WebDriver. Refer to the Link for WebElement API Methods.

Generally we mainly use methods like sendKeys(),click(),getText(). But they are so many other methods available to verify the input data entered by the user in the textbox. Verify the Css Attributes like color and font-size of the Web Element.

Is WebElement is a Interface or Class??

Answer:: Interface
WebElement is an interface and all the abstract methods in the interface are implemented by the RemoteWebElement Class. Refer to the Link to get more information on Inheritance and Interfaces.

How do we know the Class which are implementing the Interface??

Hold the control button in the keyboard and place the mouse on the method and select Open Implementation as shown below to get the details of the classes which are implementing the interface.

Classes implementing the interface WebElement

RemoteWebElement Class implementing the WebElement Interface

getCssValue("background-color")
Returns the Color of the WebElement

getCssValue("font-size")
Returns the font-size

getLocation()
Returns the Location of the WebElement. A point, containing the location of the top left-hand corner of the element

getAttribute("value")
Returns the input data entered by the user in the Text box using sendkeys() method.

Example for fetching the background-color and font-size of the Elements in the Web Page:

import java.io.IOException;
import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
public class WebElementMethods {

	public static void main(String[] args) throws IOException {
		
		System.setProperty("webdriver.gecko.driver", "geckodriver.exe");
		FirefoxDriver driver = new FirefoxDriver();
		
		driver.get("http://total-qa.com/live-examples/loginpage/");
		
		WebElement e = driver.findElement(By.id("username"));
		e.sendKeys("total-qa");
		
		String enteredText = e.getAttribute("value"); //Retrieve the value entered as total-qa
		
		System.out.println("Entered Text::  "+ enteredText);
		
		System.out.println("id:: " + e.getAttribute("id"));
		
		System.out.println("name:: " +e.getAttribute("name"));
		
		System.out.println("class:: " +e.getAttribute("class"));
		
		e.clear(); //Clear the Default Text
		 
		System.out.println("location:: " +e.getLocation());//Returns the Location of the WebElement. A point, containing the location of the top left-hand corner of the element
		
		System.out.println("size:: " +e.getSize());
		
		System.out.println("color:: " +e.getCssValue("background-color"));
		
		System.out.println("fontsize:: " +e.getCssValue("font-size"));
	
		System.out.println("Tag Name:: " + e.getTagName());
	
		
		
		
	}
}

import java.io.IOException;

import org.openqa.selenium.By;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.firefox.FirefoxDriver;

public class WebElementMethods {

public static void main(String[] args) throws IOException {

System.setProperty("webdriver.gecko.driver", "geckodriver.exe");

FirefoxDriver driver = new FirefoxDriver();

driver.get("http://total-qa.com/live-examples/loginpage/");

WebElement e = driver.findElement(By.id("username"));

e.sendKeys("total-qa");

String enteredText = e.getAttribute("value"); //Retrieve the value entered as total-qa

System.out.println("Entered Text:: "+ enteredText);

System.out.println("id:: " + e.getAttribute("id"));

System.out.println("name:: " +e.getAttribute("name"));

System.out.println("class:: " +e.getAttribute("class"));

e.clear(); //Clear the Default Text

System.out.println("location:: " +e.getLocation());//Returns the Location of the WebElement. A point, containing the location of the top left-hand corner of the element

System.out.println("size:: " +e.getSize());

System.out.println("color:: " +e.getCssValue("background-color"));

System.out.println("fontsize:: " +e.getCssValue("font-size"));

System.out.println("Tag Name:: " + e.getTagName());

}

Output:

Entered Text:: total-qa id:: username name:: username class:: textboxcolor padding location:: (268, 849) size:: (231, 30) color:: rgb(255, 255, 0) fontsize:: 13.3333px Tag Name:: input

Conclusion:

In this example we have learnt how to use the WebElement Methods in Selenium WebDriver.

XPath normalize-space example in Selenium WebDriver

total-qa August 28, 2018 No Comments

In this example we will discuss about the usage of normalize-space in Xpath.

We already aware of the Functions like text(),contains(),starts-with(),last() and position() in Xpath. Refer to this link to know details about these functions. Xpath Functions.

Generally, normalize-space(String s) is a method in Xpath useful to remove any leading or trailing spaces in a String. This is also works like a trim() function in java.lang.String class. We will see different examples

<tr>
<td>
<a href="//money.rediff.com/companies/thomas-cook-i/16610005"> Thomas Cook (I) </a>
</td>
<td>A</td>
<td>244.60</td>
<td>252.95</td>
<td>
</tr>

<tr>

<td>

<a href="//money.rediff.com/companies/thomas-cook-i/16610005"> Thomas Cook (I) </a>

</td>

<td>

</tr>

In the above example the table data has spaces for Thomas Cook. If we use Xpath Text Function it doesnt provide any value as an output. Please check the screenshot below:

[findElements Example]How to find Broken Links in a WebSite using Selenium WebDriver?

total-qa August 24, 2018 No Comments

[findElements Example]How to find Broken Links in a WebSite using Selenium WebDriver?

In Web Applications it is important to identify the Broken Links. As manual Tester when we click on hyper link if we get HTTP_404 page not found. Then it is obvious that the page is broken. It would be good to find all the HTTP Error Codes as well https://en.wikipedia.org/wiki/List_of_HTTP_status_codes.
There are different ways of identify the broken links manually using the following Add-on:
LinkChecker Addon for Firefox which helps to identify the broken links in web page opened in Firefox.
In order to identify all the links in a webpage we can use findElements() method which returns the List <WebElement>

Differences between FindElements and FindElement in Selenium WebDriver
findElement(By)
1. WebElement e = driver.findElement(By.name(“username”));
findElement(By) returns an WebElement as a return value.
2. findElement(By) throws an exception if it is unable to find an Element.
WebElement e =driver.findElement(By.name(“abc”));
NoSuchElementException is an RunTimeException/Unchecked Exception
3. findElement(By) always selects the first one in the list of matching WebElements.

findElements(By)
1. findElements(By) returns an List of WebElements
Details About List:
Click on this link to know more about Collections: java.util.Collection

List is available under java.util package.
List is mainly useful to store multiple objects which are duplicates as well.
“abc”
“abc”
WebElements which hare having same properties are known as duplicates.
size() – number of the objects available in list
get(int index)- helps in retrieving the particular object
int a[]={1,2,3,4,5};
a[0]// 0 is the index value in Arrays and it 1 in Xpath.

2.findElements(By) returns an empty list if its unable to find an element
List list = driver.findElements(By.name(“abc”));
Empty List means list.size() is zero.
3. findElements(By) selects all the matching webElements and returns a list.

Logic to Identify the Broken Links in a WebPage:

import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class BrokenLinks {
	private static WebDriver driver = null;
	public static void main(String[] args)     
	{
  		HttpURLConnection httpURLConnection = null;
  		System.getProperty("webdriver.gecko.driver","geckodriver.exe");
	 	driver = new FirefoxDriver();
 		driver.manage().window().maximize();
 		driver.get("http://total-qa.com");

		List<WebElement> links = driver.findElements(By.tagName("a"));
		for(int i = 0 ; i < links.size();i++)
		{
			String resourceUrl = links.get(i).getAttribute("href");
			try 
			{
				httpURLConnection = (HttpURLConnection)(new URL(resourceUrl).openConnection());
				httpURLConnection.connect();
				System.out.println("Valid url :: "   +resourceUrl );
				System.out.println("Response Code::" +httpURLConnection.getResponseCode());	//200 for Valid HyperLinks
			} 
			catch (IOException e) 
			{
				e.printStackTrace();
				System.out.println("Broken url :: "   +resourceUrl );
			}
		}

		driver.quit();

	}
}

import java.io.IOException;

import java.net.HttpURLConnection;

import java.net.URL;

import java.util.List;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.firefox.FirefoxDriver;

public class BrokenLinks {

private static WebDriver driver = null;

public static void main(String[] args)

{

HttpURLConnection httpURLConnection = null;

System.getProperty("webdriver.gecko.driver","geckodriver.exe");

driver = new FirefoxDriver();

driver.manage().window().maximize();

driver.get("http://total-qa.com");

List<WebElement> links = driver.findElements(By.tagName("a"));

for(int i = 0 ; i < links.size();i++)

{

String resourceUrl = links.get(i).getAttribute("href");

try

{

httpURLConnection = (HttpURLConnection)(new URL(resourceUrl).openConnection());

httpURLConnection.connect();

System.out.println("Valid url :: " +resourceUrl );

System.out.println("Response Code::" +httpURLConnection.getResponseCode()); //200 for Valid HyperLinks

}

catch (IOException e)

{

e.printStackTrace();

System.out.println("Broken url :: " +resourceUrl );

}

driver.quit();

}

Therefore we can find all the Broken Links in a WebPage using HTTPURLConnection and findElements method in Selenium WebDriver.
Hope this tutorial helps you in checking Broken links using selenium webdriver.

[Solved] java.lang.ClassCastException using Generics in Java

total-qa August 24, 2018 No Comments

[Solved] java.lang.ClassCastException using Generics in Java

Generally when ever we write the Java Logic its better to know the issues during the compile time rather than at run time. If we do not use Generics we might face java.lang.ClassCastException when trying to add an Integer Object instead of String Object and try to retrieve the value and perform an operation on it will cause this exception. How do we overcome this using Generics we will learn from this tutorial.

Lets implement the Logic without using the Generics:

import java.util.ArrayList;
import java.util.List;
public class ClassCastExceptionExample {

	public static void main(String[] args) {
		String str1 = new String("RC");
		String str2 = new String("Selenium");
		List  strList = new ArrayList();//Without using Generics
		strList.add(str1);
		strList.add(str2);
		strList.add(2);//Adding an integer instead of String
		
		String str = (String) strList.get(2);
		str.substring(0, 2);//Throws ClassCastException of performing an operation on Integer
	 	 
	}
}

import java.util.ArrayList;

import java.util.List;

public class ClassCastExceptionExample {

public static void main(String[] args) {

String str1 = new String("RC");

String str2 = new String("Selenium");

List strList = new ArrayList();//Without using Generics

strList.add(str1);

strList.add(str2);

strList.add(2);//Adding an integer instead of String

String str = (String) strList.get(2);

str.substring(0, 2);//Throws ClassCastException of performing an operation on Integer

}

Executing this Program returns following output in the Console:

Exception in thread “main” java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String
at org.h2k.javaprograms.ClassCastExceptionExample.main(ClassCastExceptionExample.java:15)

Lets implement the Logic using the Generics:
In the above program change the Line No:8 as follows:
List<String> strList = new ArrayList<String>();

import java.util.ArrayList;
import java.util.List;
public class ClassCastExceptionExample {

	public static void main(String[] args) {
		String str1 = new String("RC");
		String str2 = new String("Selenium");
		List<String>  strList = new ArrayList<String>();
		strList.add(str1);
		strList.add(str2);
		strList.add(2);//Compile Time Error at Line number 13
		
		String str = (String) strList.get(2);
		str.substring(0, 2);//Throws ClassCastException of performing an operation on Integer
	 	 
	}
}

import java.util.ArrayList;

import java.util.List;

public class ClassCastExceptionExample {

public static void main(String[] args) {

String str1 = new String("RC");

String str2 = new String("Selenium");

List<String> strList = new ArrayList<String>();

strList.add(str1);

strList.add(str2);

strList.add(2);//Compile Time Error at Line number 13

String str = (String) strList.get(2);

str.substring(0, 2);//Throws ClassCastException of performing an operation on Integer

}

Conclusion:
Therefore implementing Generics avoids ClassCastException During run time. Any issues we can caught during Compile Time.

Rerunning failed tests using IRetryAnalyzer,ITestResult in TESTNG

total-qa August 22, 2018 No Comments

Rerunning failed tests using IRetryAnalyzer,ITestResult in TESTNG

TESTNG is a java framework used by JAVA Developers to perform unit testing of their code.
We can even use TESTNG for Selenium to automate the manual testcases and verify the output by inserting
the Soft Assertions and Hard Assertions. TESTNG generates the reports once the testcase run completed.
It generates the test-output directory with results in index.html and emailable-report.html. It also generates the testng-failed.xml for the tests which are failed in the Suite. Now it is possible to re-run the failed tests.
Mostly the Selenium tests will fail due to multiple reasons, one of them is NoSuchElementException this occurs due to TimeOut Issues where the element takes time to display. In those cases it would be good to re-run and fix the issues.

Steps for Implementing the Retry Logic:

1. IRetryAnalyzer is an interface which has to be implemented the Class RerunTests.java.

import org.testng.IRetryAnalyzer;
import org.testng.ITestResult;
 
public class RerunTests implements IRetryAnalyzer {
 
  private int retryCount = 0;
  private static final int maxRetryCount = 2;
 
  @Override
  public boolean retry(ITestResult result) {
    if (retryCount < maxRetryCount) {
      retryCount++;
      return true;
    }
    return false;
  }
}

import org.testng.IRetryAnalyzer;

import org.testng.ITestResult;

public class RerunTests implements IRetryAnalyzer {

private int retryCount = 0;

private static final int maxRetryCount = 2;

@Override

public boolean retry(ITestResult result) {

if (retryCount < maxRetryCount) {

retryCount++;

return true;

}

return false;

}

2. Write the TestNG Testcase that has to be re-run. Use TESTNG attribute retryAnalyzer and provide the value for the attribute as RerunTests.java.

import org.testng.Assert;
import org.testng.annotations.Test;
 
public class SanityTests
{
 
  @Test(retryAnalyzer = RerunTests.class)
  public void m1()
 {
    Assert.assertTrue(false);//Fail the testcase
  }
}

import org.testng.Assert;

import org.testng.annotations.Test;

public class SanityTests

{

@Test(retryAnalyzer = RerunTests.class)

public void m1()

{

Assert.assertTrue(false);//Fail the testcase

}

3. Finally the failed testcase executes as per the retryCount mentioned in the RerunTests.java.
