Software Testing
Software Testing
Software Testing is a process used to identify the correctness,
completeness and the quality of developed compute software. It includes a
set of activities conducted with intent of finding errors in software so that
it could be corrected before the product is released to end users.

Manual testing is essentially self-
explanatory — testing of a web
application is done manually, by
human action
Automated testing uses the
assistance of tools, scripts, and
software to perform test cases by
repeating pre-defined actions

Automation Testing Interview Questions
01 What do you mean by the term Automation Testing?
Test Automation is a process of automating the manual
process to test the application/system under test.
Automation Testing

02 What are different types of Automation Testing?
Unit Tests
GUI Tests
Functional Tests

03 What is an automated test script?
An automated test script is a short program that is written
in a programming language to perform a set of
instructions on an application

04 What are good coding practices that should be followed while writing
test cases for automation?
<Use comments at appropriate places>
<Maintain separate files for reusable functions>
<Follow coding conventions>
<Run scripts regularly>

05 What is a Test Automation Framework?
A framework is a set of the structure of the entire
automation suite. It is also a guideline, which if followed
can result in a structure which is easy to maintain and
enhance.

08 What are pre-requisites to start automation testing?
Stable build
List of repeated functionality
List test data
Automation Framework
Skilled Resources
Filter Test Case Scenario

09 What are the factors that determine the effectiveness of Automation
Testing?
▪ Time saved
▪ Defects found
▪ Test coverage
▪ Maintenance Time
▪ Instalment cost
▪ Test reusability
▪ Quality of software under
test

10 What are main differences between Automation Testing & Manual
Testing?
▪ Test results are not reliable ▪ Automated testing is more reliable
▪ Process is time consuming ▪ Significantly faster approach
▪ Automated Testing is suited
for Regression Testing,
Performance Testing etc
▪ Manual Testing is suitable
for Exploratory, Usability
and Adhoc Testing
▪ Initial investment cost is low ▪ Initial investment cost is high

11 Is it possible to achieve 100% automation?
Usually, it is not usually possible, or necessarily desirable, to achieve
100% Test Automation. Because there would be many edge test cases
and some cases which are executed seldom

12 What are some conditions where we cannot consider
automation testing?
➢ Ever changing requirements
➢ Exhaustive documentation
➢ Only suitable for CI/CD
➢ One time test case
➢ Ad-hoc testing
➢ Exploratory testing
➢ User interface testing

13 How many test cases can you automate in a day?
How many test cases
can you automate?
Well it depends on the
test case scenario
complexity and length

14 What are some modern applications of Automation Testing?
Amazon – Delivery
Drones
Google – Self Driving
Cars
Starbucks – Robo
Cashiers
Facebook – Brain
Computer Interface

15 Is documentation necessary in Automation Testing?

16 Can automation testing replace manual testing?
No more manual
testing?
Automation testing isn’t a replacement for manual
testing. It’s just a continuation of the manual testing.

17 What are some popular Automation Testing Tools worldwide?
Selenium
Appium Watir
Ranorex

18 When should you prefer Manual Testing over Automation Testing?
Ad-hoc or exploratory
testing
Project is short term
Flexibility is needed
Usability testing is
performed

When is Automation testing useful? Which test cases to Automate?
Repetitive Tasks
Environment
Setup/Tear Down
Data Entry Tasks
Timing or Screening
Responsiveness
Non Functional
Testing
Capturing Results
19

20 How to implement automation, what would be the steps?
Test Tool
Selection1
Define Scope of
Automation
2
Planning, Design &
Development3
Test Execution4
Maintenance5

21 What are different approaches to Test Automation?
Focus on if various sections of
code are performing as per
expectations under different
conditions or not
Code-driven Testing Graphical User
Interface
Application’s having GUI’s can
be tested using this method to
record user actions and
responses
Framework Approach
The framework brings together
function libraries, test data
sources, object details and other
reusable modules

22 What are the points that are covered while planning phase of
automation?
Decide the right automation tool
Choose automation framework if needed
Define scope of automation
Develop test cases
Test environment configuration
Identify test deliverables
Develop test suites

How to decide the tool that one should use for Automation testing
in their projects?
23

Good debugging facility
Robust object identification Support multiple frameworks
Testing of a database
Test environment support

25 On what basis you can map the success of automation?
Defect Detection Ratio
Automation Execution Time
Reduce in labour cost

26 What is the scripting standard while performing automation testing?
Uniform naming convention
Regular commenting

33 Is Automation Testing a Black-box testing or a White box testing?
Black – Box
Testing
TEST CASE - OUTPUT
In black box, internal
structure/design/implementation of
the item being tested is not known to
the tester
TEST CASE - INPUT
White – Box
Testing
TEST CASE - OUTPUTTEST CASE - INPUT
In white box, internal
structure/design/implementation of
the item being tested is known to the
tester.

34 Is Automation Testing a Black-box testing or a White box testing?
Automation Testing can be both
black box testing & white box testing
depending on the scenarios in which
automation is performed.
Black – Box
Testing
White – Box
Testing

34 What are attributes of a good Test Automation Framework?
A framework is a set of the structure of the entire
automation suite. It is also a guideline, which if
followed can result in a structure which is easy to
maintain and enhance.

Reusable
Consistent
Independent
Logging & Reporting
Integration

35 What are Test Automation Framework development challenges?
Setting scope
of automation
Identifying
requirements
Selecting tool

36 What is data-driven testing?
Data-driven is a test automation framework which stores test data in
a table or spread spreadsheet format.
