Question 9

Library Architecture Framework

Answer 9

1. This framework is derived from the modular framework that aims to provide a greater level of modularity to testing by breaking down tests by units, functions, etc.
2. The library architecture framework identifies similar tasks within test scripts and groups them by function. These modular parts aren’t directly about function—they’re more focused on common objectives. Then these functions are stored in a library sorted by their objectives, and test scripts call upon this library to obtain different functionality when testing.

OR

1. More development time
2. High technical knowledge required
3. Complicated

Question 12

Data-Driven Framework

Answer 12

• 1. The data-driven test automation framework is focused on separating the test scripts logic and the test data from each other.
     
     1. It allows us to create test automation scripts by passing different sets of test data.
     2. The test data set is kept in the external files or resources such as MS Excel Sheets, MS Access Tables, SQL Database, XML files, etc.,
     3. The test scripts connect to the external resources to get the test data.
     4. By using this framework we could easily make the test scripts work properly for different sets of test data.
     5. This framework significantly reduces the number of test scripts compared to the module-based framework.

3. Need experienced automation testers to design framework

OR

1. High setup time
2. Excellent technical knowledge required
3. Troubleshooting is difficult

Question 15

Keyword Driven Testing Framework

Answer 15

1. It is also known as table-driven testing or action word based testing.
2. In Keyword-driven testing, we use a table format to define keywords or action words for each function or method that we would execute.
3. It performs automation test scripts based on the keywords specified in the excel sheet.
4. By using this Framework, testers can work with keywords to develop any test automation script, testers with less programming knowledge would also be able to work on the test scripts.
5. The logic to read keywords and call the required action mentioned in the external excel sheet is placed in the main class. Keyword-driven testing is similar to data-driven testing.
6. Even though to work on this framework doesn’t require much programming skills but the initial setup ( implement the framework) requires more expertise.

Question 16

Advantages of Keyword-Driven Framework

Answer 16

1. No need to be an expert to write test scripts
2. It is possible to reuse the code. We can point the different scripts to the same keyword
3. Even though application changes, test scripts don’t change
4. Tests can be designed before developing the application
5. Test scripts work independently of an application under test with basic modifications
6. Not dependent on test tools

Question 18

Hybrid Driven Testing Framework

Answer 18

Hybrid Test automation framework is the combination of two or more frameworks mentioned above. It attempts to leverage the strengths and benefits of other frameworks for the particular test environment it manages. Most of the teams are building this hybrid driven framework in the current market.

Question 19

Behavior Driven Development Testing Framework

Answer 19

The purpose of this Behavior Driven Development framework is to create a platform that allows everyone (such as Business Analysts, Developers, Testers, etc,) to participate actively. It requires increased collaboration between Development and Test Teams. It doesn’t require the users to be acquainted with a programming language. We use non-technical, natural language to create test specifications. Some of the tools available in the market for Behavior Driven Development is JBehave, Cucumber, etc.,

Question 20

Why Do We Need a Test Automation Framework?

Answer 20

1. Optimization of Resources
   It does this by facilitating the use of different resources according to organizational needs.
2. Increased Volume of Testing
   Test automation frameworks increase the volume of testing.
3. Simultaneous Testing
   Enable simultaneous testing of different types of devices. When the test scripts are automated, all testers need to do is run them on different devices. Since the parameters are same, testers can quickly generate comparative test reports.
4. Enhanced Speed and Reliability
   Reduce the time to carry out these activities. You can simultaneously run all the scenarios and get the test results in very little time.
5. More Output in Less Time
   An automation script minimizes the time taken to prepare and run tests. With increased efficiency and speed, a firm can gain more output in less time.
6. Fixing Bugs at an Early Stage
   Helps in fixing bugs at an early stage.
7. Remote Testing
   You can start running a test before leaving. When you come back after a few hours, the test results will be ready.
8. Reusable Automation Code
   You can reuse test automation scripts in a different application.
9. Increased ROI
   The initial investment involved in test automation frameworks is off-putting for many. But the long-term return on investment is high.
10. Continuous Testing
    The importance of continuous integration and continuous delivery/deployment can’t be overstated.

Question 21

How to build a test automation framework?

Answer 21

1. first learn what the application does
2. pick framework
   — data driven
3. pick tools to use
   — selenimum
   — java (a lot of java automation testers)
   — TestNG annotations: used for assertions, grouping and parallel execution
   *****Integrating the TestNG dependency in the POM.xml file and running this POM.xml file using Jenkin
   — Git (verizon contol): use a repository to store test scripts
   — Maven: used for build execution and dependency purpose
   ***** create Maven project
4. Create Test Base Class (src/test/java/tests)
   — contains all the common functions used by all the pages
   — responsible for loading the configurations from property files (see bullet 5)
   — opening/closing browser
   — initialize implicit wait
   — setup webdriver
   — setup reports
   — create object of file input stream points to file which data should be read
5. Property files (config.properties src/main/java/config/)
   — contains information that remains static throughout
   — URL, browsers, screenshots path
   — could contain browser type, URL
   — testing annotations should go here
6. Page object model with page factory page
   — use to keep locators (i.e. id, path) from test code
   — design pattern with page factory page object model
   — each web page has a separate class (src/main/java/page)
   — class holds the functionality and members of the
   — each individual test has a separate class (src/test/java/tests)
   — separate packages for pages and test script
7. Execute maven project using jenkins (look at webpage)
   — integrating the testing dependency in the pom.xml file and run the pom.xml using Jenkins
   Continuous Integration Tools)
   — execute on a daily basis and at nightly by schedule
   — Test Results will be sent to the peers using Jenkins
8. Test data held in excel under (src/main/java/testdata)
   — Apache POI to handle excel sheet
   — Parameterize tests using Excel files
9. Utility class (src/main/java/util/TestUtil.java)
   — Stores and handles the functions (The code which is repetitive in nature such as waits, actions, capturing screenshots, accessing excels, sending email, etc.)
   — Functions can be commonly used across the framework.
   — Created to achieve reusability.
   — Extends the TestBase class to inherit the properties of TestBase in TestUtil.
10. Error screenshot and logs
    — screenshots separate folder (src/test/java/FailedTestsScreenshots)
    — screenshots of failed test cases will be added to extend reports
11. Extent reports (src/test/java/test-output)
    — An open-source reporting library used in selenium

Question 22

Where you have applied OOPS in Automation Framework

ABSTRACTION

Answer 22

#1. ABSTRACTION
Abstraction is the methodology of hiding the implementation of internal details and showing the functionality to the users.

In Page Object Model design pattern, we write locators (such as id, name, xpath etc.,) and the methods in a Page Class. We utilize these locators in tests but we can’t see the implementation of the methods. Literally we hide the implementations of the locators from the tests.

Question 23

Where you have applied OOPS in Automation Framework

INTERFACE

Answer 23

#2. INTERFACE
Basic statement we all know in Selenium is WebDriver driver = new FirefoxDriver();

Detailed explanation on why we write WebDriver driver = new FirefoxDriver(); in Selenium.

WebDriver itself is an Interface. So based on the above statement WebDriver driver = new FirefoxDriver(); we are initializing Firefox browser using Selenium WebDriver. It means we are creating a reference variable (driver) of the interface (WebDriver) and creating an Object. Here WebDriver is an Interface as mentioned earlier and FirefoxDriver is a class.

An interface in Java looks similar to a class but both the interface and class are two different concepts. An interface can have methods and variables just like the class but the methods declared in interface are by default abstract. We can achieve 100% abstraction and multiple inheritance in Java with Interface.

Question 24

Where you have applied OOPS in Automation Framework

INHERITANCE

Answer 24

#3. INHERITANCE
The mechanism in Java by which one class acquires the properties (instance variables) and functionalities of another class is known as Inheritance.

We create a Base Class in the Automation Framework to initialize WebDriver interface, WebDriver waits, Property files, Excels, etc., in the Base Class.

We extend the Base Class in other classes such as Tests and Utility Class.

Here we extend one class (Base Class like WebDriver Interface) into other class (like Tests, Utility Class) is known as Inheritance.

Question 25

POLYMORPHISM

Answer 25

#4. POLYMORPHISM
Polymorphism allows us to perform a task in multiple ways.

Combination of overloading and overriding is known as Polymorphism. We will see both overloading and overriding below.

Question 26

Where you have applied OOPS in Automation Framework

POLYMORPHISM - METHOD OVERLOADING

Answer 26

#4a: METHOD OVERLOADING
We use Implicit wait in Selenium. Implicit wait is an example of overloading. In Implicit wait we use different time stamps such as SECONDS, MINUTES, HOURS etc.,

Action class in TestNG is also an example of overloading.

Assert class in TestNG is also an example of overloading.

A class having multiple methods with same name but different parameters is called Method Overloading

Question 27

Where you have applied OOPS in Automation Framework

POLYMORPHISM - METHOD OVERRIDING

Answer 27

#4b: METHOD OVERRIDING
We use a method which was already implemented in another class by changing its parameters. To understand this you need to understand Overriding in Java.

Declaring a method in child class which is already present in the parent class is called Method Overriding. Examples are get and navigate methods of different drivers in Selenium .

Question 28

Where you have applied OOPS in Automation Framework

ENCAPSULATION

Answer 28

#5. ENCAPSULATION
All the classes in a framework are an example of Encapsulation. In POM classes, we declare the data members using @FindBy and initialization of data members will be done using Constructor to utilize those in methods.

Encapsulation is a mechanism of binding code and data (variables) together in a single unit.
