Automation Framework Set

 

Automation Framework Set 

(Interview Questions 1) 

 

1. Explain your Automation Framework?

 

Note: Whenever you answer this question, then make sure that you follow the revere 

Approach while describing the whole framework component

 

Start from Jenkins Project -> Scheduler ->parameter capturing-> and then whole Framework.

 

(One of the Key point to remember is the choice of your words. And the depth you go to explain the answer)

 

a. Overview

i. We have created a single Hybrid framework that helps us to test (UI), (API) and

Mobile Components of our entire system ii. The Benefit:

a. of this approach was that we really don’t need to maintain 3 different repositories.

iii. Our git branching Model helps us making sure that everyone is working on the updated piece of code and the test code only becomes part of the CT pipeline when it’s approved by the team lead.

1.       The benefit of this approach is that we tell our team to write good and well 

2.       Maintainable tests that add values in our automated tests.

 

 

b. Jenkins Project:

i.        The Jenkins Plan that we have created is a Parameterized Jenkins Plan

ii.      All the Run time arguments that are required for the framework i.e

1.           Test Type: (Sanity/Smoke/E2e)

2.           Component Type: (API/UI/Android)

3.           Env Type : Dev/QA/UAT iii. These parameters are selected to from the Jenkins Project and Passed to our Frameworks- Runner Class (which has the main function inside it).

 

Few Extra Questions: •       How to Create Parameterized Job in Jenkins and Read them in Code? •       How to Read Runtime Arguments in Java? •       Explain your Branching Model?

 

 

c. Runner Class:

i.          All the selected Parameters from Jenkins are passed to the Runner Class which has the main function as the Run time arguments

ii.        These Run time arguments are validated and based on them our Dynamic TestNG.xml file is created and executed!

iii.      Example:

1.       If component type is api then our package whose name is com.api.tests will be executed

2.       In com.api.tests we may have 500 tests and out of those 500 tests we want to run only sanity

3.       TestType parameter helps in including those tests in our dynamic.xml

file

4.       Lastly the env type helps in which property file to pick up from the config folder

 

d. Test packages:

i. We have 3 tests packages

1.       com.api.tests

2.       com.ui.tests

3.       com.api.tests

 

ii. While writing our tests we have ensured that all tests are 1. (Characteristic of a good test) very important

a.           Small

b.           Independent

c.           Belongs to certain group

d.           Easy to read

e.           Have Proper Assertions iii. Design Pattern Used: Fluent Design Pattern

iv. OOPS concepts Used: Inheritance/ Encapsulation/ this keyword/super keyword

Few Extra Questions: •       How did you create the Dynamic TestNG xml for execution? (Very Important) •       How do you run only specific Tests from your framework? •       How do you ensure that your team is writing High Quality Tests?

               

e. DAO Component

i.          DAO is our Data Access Object Component.

ii.        It consist of Special DAO classes which are mapped to our Database tables.

iii.      There is a DB helper class which follows the Singleton design pattern which helps in connecting to the Database

iv.      The functions in DAO classes:

1. Fires the SQL query to the database and retrieves the values and create a LIST of POJO or a simple POJO object and returns it back

v.          We use DAO component functions for our DB Validation and E2E test

vi.        Design Pattern Used: Singleton Design Pattern

vii.       OOPS concepts Used: Inheritance/ Encapsulation/ this keyword/super keyword.

Few Extra Questions: •       What is Singleton Class and where you have used it? •       How do you connect to your database in Java? •       How did you do DB validation in your framework? •       Can a constructor of a class be private? •       What exceptions are shown when you try use JDBC? •       Which Database your project uses? •       What is DAO?

               

 

              f.     Page Classes Component:

i.          For UI Automation we have used Page Classes

ii.        For all unique component of UI there is a specific page class present

iii.      Each Page Class consist of

1.       Private static final By (Locators)

2.       A Parameterized Constructor

3.       Functionality of that page

a. Each function of the Page class returns some data or page object of the next UI Page.        

Few Extra Questions: •       Benefit of Page Classes •       Explain Page Object Design Pattern •       What the are the substitute of Page Object Design Pattern? •       What are page objects?

 

g. Listeners Component:

a. There 2 major listeners in our Project

i. ITestListeners

1.                   This is used for generating reports

2.                   Logs

3.                   Taking screenshot of failed Test ii. IRetryListeners

1. This is used to re run failed test dynamically

Few Extra Questions: •       Which Listeners Used in your Project? •       What are the different interfaces used in your Project? •       How to do you generate Report and Log in your Project? •       How do you run failed Test?

 

 

h.      POJO Component:

i.         For Sending Request Body to our API Test we have used to the POJO

ii. Each Request Body has a specific POJO Class

Few Extra Questions: •       How do you pass PAYLOAD or request body to the API Request •       What is the purpose of POJO?] •       How do you validate complex JSON Response? •       How do you convert POJO to JSON? •       How do your convert JSON to POJO?

 

               

j.        Test Data Component

i. Our Framework can use Test Data from

1.       Excel using apache poi

2.       CSV using open csv

3.       Database using JDBC

4.       Fake Data Creation using JavaFaker

Few Extra Questions: •       How to read excel file in Java? •       How to read CSV file in Java? •       How to read Properties File in Java? •       How do you connect to Database in Java? •       How did you create Fake Data in your Framework? •       How did you achieve data driven testing in your framework? •       How do you pass test data from file to test

o.      Browser Utility Component:

i.       While creating the framework we are NOT supposed to used to any Selenium function directly

ii.     All selenium functions will be wrapped under a special wrapper functions. iii. These wrapper functions creates abstraction in your framework iv. Browser Utility is a class which contains these wrapper function which consist selenium methods.
