Steps to Launch the ChromeBrowser without using chromedriver.exe

total-qa February 9, 2019 4 Comments

Selenium WebDriver automation tool is mainly useful to run tests against multiple Browsers such as Chrome Browser,Firefox Browser,Internet Explorer Driver.Running the tests against multiple browsers is known as Cross Browser Testing.
To launch the Browser in Selenium WebDriver we need to set the path of the executable available in the laptop. Following that we have to instantiate the driver instance based on the Driver instance. In order to avoid these steps we can use the WebDriverManager class.

WebDriverManager

WebDriverManager allows to automate the management of the binary drivers (e.g. chromedriver, geckodriver, etc.) required by Selenium WebDriver.
Using WebDriverManager its not required to maintain the below lines of the code for launching the browser.
System.setProperty(“webdriver.chrome.driver”, “/path/to/binary/chromedriver”);
System.setProperty(“webdriver.gecko.driver”, “/path/to/binary/geckodriver”);
System.setProperty(“webdriver.opera.driver”, “/path/to/binary/operadriver”);
System.setProperty(“phantomjs.binary.path”, “/path/to/binary/phantomjs”);
System.setProperty(“webdriver.edge.driver”, “C:/path/to/binary/MicrosoftWebDriver.exe”);
System.setProperty(“webdriver.ie.driver”, “C:/path/to/binary/IEDriverServer.exe”);

WebDriverManager Maven Depdendency

To use the WebDriverManager class ensure the following depedency is added in the maven project object model (pom.xml) file.

<dependency>
       <groupId>io.github.bonigarcia</groupId>
	<artifactId>webdrivermanager</artifactId>
	<version>3.2.0</version>
</dependency>

<groupId>io.github.bonigarcia</groupId>

Capturing screenshot using java.awt.Robot class-Selenium WebDriver

total-qa February 3, 2019 No Comments

The java.awt.Robot class is mainly useful to perform native actions where keyword and mouse actions to be performed. This actions are helpful for automation. If the current platform configuration does not allow input controls, an AWTException will be thrown when using the java.awt.Robot class. In this post we will java.util.Robot class for capturing the screenshots. The method createScreenCapture(Rectangle screenRect) is available in java.awt.Robot class which helps to create an image containing pixels read from the screen.The java.awt.Rectangle object to be passed as an parameter for capturing the screenshot. To create an Rectangle object the java.awt.Dimension[Height*Width] object to be passed as an parameter.

API Classes and Methods useful to capture the Screenshot as follows:

Robot Class Object
Rectangle Class Object
Dimension Class Object- Input Parameters Height * Width

Regex Pattern Matching in JAVA – String Functions startsWith(),endsWith(),contains()

total-qa February 2, 2019 No Comments

To identify particular pattern of regular expressions in Strings is achieved in JAVA by using the API java.util.regex. This API consists of two main java classes such as Matcher and Pattern classes. Also we can even use String Functions to identify the particular pattern of regular expressions in the String class.

Pattern Class

A regular expression specified as a String is passed into an instance of this class.
The output is used to create a Matcher object that can match the character sequences against the regular
expression.

Static methods available in the Pattern Class as follows:

pattern()

split()

matcher()

compile()

matches()

Matcher Class

This java class helps to matches the character sequences by interpreting the pattern.

Static Matcher Methods in the API:

start()

end()

group()

String Functions to identify the Regular Expressions:

startsWith(String prefix)

endsWith(String suffix)

contains(CharSequence s)

Dynamic Input Test Data Generation: Best Practices,Random Java API

total-qa    January 27, 2019 January 28, 2019    No Comments on Dynamic Input Test Data Generation: Best Practices,Random Java API

In Testing it is important to provide input data to complete the execution of Test-cases. Irrespective of any type of testing such as Functional Testing,Integration Testing,System Testing and Performance Testing the input data plays a vital role.
In Automation tools such as Selenium WebDriver the input data can be maintained in three different ways:

1. Maintain parameters in the testng.xml. Read the parameter values using @Parameters annotation.
2. Maintain input data in the Excel File. Read the data and pass the values using @DataProvider annotation.
3. Input Data in the properties file.

In the above 3 cases, the input data stored is static. If we suppose, the dynamic data should be generated used in the execution flow of test cases. We have to Java API to generate the dynamic data.
So, we will go through now how to generate the random/dynamic input data.

Note:
Do not get confuse with the dynamic object properties. In this post we are discussing about only the input data.

Generating two digit Random Number

java.util.Random is a java class available for generating random integers.

package totalqa; import java.util.Random; public class DynamicInputData{ public static void main(String args[]) { int uLimit = 99; int lLimit = 10; int val = lLimit + rand.nextInt(uLimit - lLimit ); System.out.println("2 digit Random Number:"+ val); } }

                int lLimit = 10;
int val = lLimit + rand.nextInt(uLimit - lLimit );
System.out.println("2 digit Random Number:"+ val);

}
}

Generating three digit Random Number

package totalqa; import java.util.Random; public class DynamicInputData{ public static void main(String args[]) { int uLimit = 999; int lLimit =100; int val = lLimit + rand.nextInt(uLimit -lLimit ); System.out.println("3 digit Random Number:"+ val); } }

{
int uLimit = 999;
int lLimit =100;
int val = lLimit + rand.nextInt(uLimit -lLimit );
System.out.println("3 digit Random Number:"+ val);

}
}

Generating Random ASCII Character

To generate the random characters we should glance through the ASCII table from this link.
http://www.asciitable.com/

Lower Case Alphabets– Decimal Number Ranging from 97 to 122

Upper Case Alphabets– Decimal Number Ranging from 65 to 90

package totalqa; import java.util.Random; public class RandomASCII{ public static void main(String args[]) { //Generating Random Upper Case ASCII Characters char ch = (char) (65+rand.nextInt(26)); System.out.println(ch); } }

{
                //Generating Random Upper Case ASCII Characters
char ch = (char) (65+rand.nextInt(26));
System.out.println(ch);

}
}

Generating five digit Random Number

package totalqa; import java.util.Random; public class DynamicInputData{ public static void main(String args[]) { //Generate a 5 digit unique number System.out.println(Calendar.getInstance().getTimeInMillis()%100000); } }

}
}

Conclusion:

The Dynamic input data generated is useful to execute the test case in different Testing Environment without any dependency on resource files.

[CSS Tips]white-space-hyphen-minus selenium

total-qa    January 1, 2019 January 28, 2019    No Comments on [CSS Tips]white-space-hyphen-minus selenium

In this tutorial we will discuss about the identifying the Selenium Locator for the Css (Cascading Style Sheets) in the following scenario’s

white spaces in an Web Element attribute value

hyphen-minus (-) in an Web Element attribute value

Attribute Selector

Type Selector

HTML Source Code for a Text-box having spaces for attribute id value:

Represents an element with the attribute whose value is a white space-separated list of words, one of which is exactly “val”.
id="pass word".

Syntax:

[att~=val]

Examples:

[id~=pass] [id~=word]

Selenium Locators-Css white space

HTML Source Code for a Text-box having hyphen-minus for attribute id value:

id="pass-word".

Syntax:

Represents an element with the attribute, its value either being exactly “val” or beginning with “val” immediately followed by “-”
[att|=val]

Examples:

[id|=pass]
Css attribute value having hyphen-minus special character

Attribute Selector:

Match when the element sets the “att” attribute, whatever the value of the attribute.

Example:

[id] – Selects all the Elements having ‘id’ attribute.
[type]- Selects all the Elements having ‘type’ attribute.

Css Locator – identify all the elements having type as attribute

Type Selector:

Matches every instance of element Type.

Example:

h1 – Selects all the elements having h1 as tag-name.
input- Selects all the elements having input as tag-name.

Type Selector in CSS

Conclusion:

In this topic we have discussed about Handling CSS attribute values from Selenium Web-driver perspective which are having white spaces and special characters hyphen-minus (-).

[Solved]SessionNotCreatedError: Unexpected error launching Internet Explorer

total-qa    September 16, 2018 January 28, 2019    No Comments on [Solved]SessionNotCreatedError: Unexpected error launching Internet Explorer

In this tutorial we will discuss about Fixing the issues that arises during execution of Selenium WebDriver tests against the browser Type Internet Explorer. Before Running Tests, make sure the following settings are updated for the Internet Explorer.

Browser Zoom Level

Access File Menu->View->zoom should be set to 100%.

Protected Mode Settings

Access File Menu->Tools-> Internet Options->Security.
Make sure the Protected Mode is enabled or disabled for all the Security Zones as listed below:

Internet Zone

Local intranet

Trusted Sites

Restricted Sites

Enabled or Disable Protected Mode

Executable File

Add the IEDriverServer.exe to the eclipse project by downloading from the link https://www.seleniumhq.org/download/

Untrusted SSL Certificate

To Handle the SSL Certificates on IE Browsers use the following code snippet to Handle SSL Certificates. This logic clicks on the link Continue to this website(recommended)

driver.navigate().to(“javascript:document.getElementById(‘overridelink’).click()”);

Selenium WebDriver Program:

import org.openqa.selenium.ie.InternetExplorerDriver; public class IEDriverTests { public static void main(String[] args) { System.setProperty("webdriver.ie.driver", "IEDriverServer.exe"); //open the browser without any url InternetExplorerDriver driver = new InternetExplorerDriver(); //enter the url driver.get("http://www.indeed.co.in"); //retrieve the title String title = driver.getTitle(); //Prints the title in the console System.out.println("Title of the page " + title); //close the browser driver.close(); } }

public class IEDriverTests {

public static void main(String[] args) {

       System.setProperty("webdriver.ie.driver", "IEDriverServer.exe");

//open the browser without any url
InternetExplorerDriver driver = new InternetExplorerDriver();

//enter the url
driver.get("http://www.indeed.co.in");

//retrieve the title
String title = driver.getTitle();

//Prints the title in the console
System.out.println("Title of the page " + title);

//close the browser
driver.close();
}
}

Conclusion

Therefore, setting the zoom to 100% and enabling or disabling the protected mode for all the security zones resolves the SessionNotCreatedError.

Software Testing Interview Questions

total-qa    September 11, 2018 September 11, 2018    1 Comment on Software Testing Interview Questions

Software Testing Interview Questions
In this article, we see best interview questions of Software Testing. Let’s get started.

What is Test Harness?
A test harness is the collection of software and test data configured to test a program unit by running it under varying conditions which involves monitoring the output with expected output.

What is Integration Testing?
Integration Testing is the process of testing the interface between the two software units. Integration testing is done by three ways. Big Bang Approach, Top Down Approach, Bottom-Up Approach

What is Adhoc Testing?
Ad-hoc testing is quite opposite to the formal testing. It is an informal testing type. In Adhoc testing, testers randomly test the application without following any documents and test design techniques. This testing is primarily performed if the knowledge of testers in the application under test is very high. Testers randomly test the application without any test cases or any business requirement document.
What are the principles of Software Testing?
1. Testing shows presence of defects
2. Exhaustive testing is impossible
3. Early testing
4. Defect clustering
5. Pesticide Paradox
6. Testing is context depending
7. Absence of error fallacy

What is Defect clustering?
Defect clustering in software testing means that a small module or functionality contains most of the bugs or it has the most operational failures.

What is Pesticide Paradox?
Pesticide Paradox in software testing is the process of repeating the same test cases, again and again, eventually, the same test cases will no longer find new bugs. So to overcome this Pesticide Paradox, it is necessary to review the test cases regularly and add or update them to find more defects.

What is Bug Leakage?
A bug which is actually missed by the testing team while testing and the build was released to the Production. If now that bug (which was missed by the testing team) was found by the end user or customer then we call it as Bug Leakage.

What is Showstopper Defect?
A showstopper defect is a defect which won’t allow a user to move further in the application. It’s almost like a crash.
Assume that login button is not working. Even though you have a valid username and valid password, you could not move further because the login button is not functioning.

What is State Transition?
Using state transition testing, we pick test cases from an application where we need to test different system transitions. We can apply this when an application gives a different output for the same input, depending on what has happened in the earlier state.

What is Defect Age?
Defect age can be defined as the time interval between date of defect detection and date of defect closure.
Defect Age = Date of defect closure – Date of defect detection
Assume, a tester found a bug and reported it on 1 Jan 2016 and it was successfully fixed on 5 Jan 2016. So the defect age is 5 days.

If you have any queries, please comment below.
