Automation testing refers to automatically testing software by writing test scripts that execute without human intervention. It automates repetitive test cases to reduce testing time and costs. Benefits include faster execution allowing for continuous integration and testing large data sets. Popular open-source tools like Selenium allow scripting in multiple languages while paid tools like UFT and TestComplete support both web and desktop testing. Key criteria for selecting a tool include skills, cost, features, support, and integration capabilities.

3. What is automation testing?

4. Automation testing
 Automation testing refers to the automatic
testing of the software in which developer or
tester write the test script once with the help of
testing tools and framework and run it on the
software.
 The test script automatically test the software
without human intervention and shows the result
(either error, bugs are present or software is free
from them).

5. Automation testing
 Automation testing is a type of software testing
that involves automated test case execution using
an automation tool.
 Automation testing needs manual effort when
creating initial scripts, and further process is
performed automatically to compare the actual
testing result with expected results. This can be
performed at these levels a) unit-level automation,
b) API testing c) user interface.

6. Automation testing
 It automates the manual testing process.
 The tester writes test scripts and then runs the test
scripts either on-demand or schedule them for
periodic executions.
 This reduces the overall testing time, thus helping
in faster product releases.

7. What to Automate?
 1. Test cases that test critical functionality of the
application
 2. Test cases that require repeated test execution
with a large dataset
 3. Tests that are time-consuming
 4. Test cases that require parallel execution

8. What not to Automate?
 1. UI test cases
 2. Usability test cases
 3. Functionalities that are rarely used and take
time for scripting
 4. Exploratory testing

9. Advantages of Automation testing
 Automation testing reduces the overall test execution time
 It reduces the cost and resource requirements of the
project.
 Helps in creating a Continuous Integration environment
wherein, after each code push, automatic test suite
execution takes place with the new build. Using CICD tools
like Jenkins, we can create Jobs that execute the test cases
after the deployment of a build and mails the test results to
the stakeholders.
 Helps in working with a large set of input which isn’t be
feasible with manual testing.

11. Popular Test Automation Testing
Tools
 Selenium
 Selenium is an open-source test automation tool. It has a very large and active
community. It has the maximum market share among all the popular tools and supports
scripting in multiple languages – Java, Python, Ruby, Javascript, C#, etc. Download link –

 Katalon Studio
 A fairly new tool but rapidly getting popular due to record and playback features along
with scripting for more technical users. It is free but not open source.
 UFT One
 A paid tool by Microfocus that can be used for automation of both Web and Windows
applications. It supports scripting in VBScript only.
 TestComplete
 A paid tool provided by Smartbear can be used for automation of Web, Mobile as well as
Desktop applications.
