1.
What is Software Test Automation ?
Answer: Software test automation is the process of
using specialized tools and software to execute pre-scripted tests on a
software application, program, or system. It involves automating the manual
testing processes using an automation tool to reduce the effort and time
required for testing. Automated testing is designed to improve software quality
by finding defects, errors, and bugs in the software under test.
In other words, software test automation involves the use of
software tools to perform repetitive and time-consuming tests on software
applications. Automation can be used to test a wide range of software
applications, including web applications, mobile apps, desktop software, and
more.
Here are some examples of software test automation:
- Regression
testing: Regression testing is a type of software testing that involves
retesting the application after making changes or modifications to the
code. Regression testing can be time-consuming, but it is critical to
ensure that the new changes did not introduce any new bugs or issues.
Automation tools can be used to perform regression testing quickly and
efficiently.
- Unit
testing: Unit testing is a type of testing that is performed at the
smallest unit of code, such as a function or method. Automated unit
testing tools can help to ensure that each unit of code is working as
intended.
- Functional
testing: Functional testing is a type of software testing that checks the
software's functionality against the requirements or specifications.
Functional testing can be automated using tools that can simulate user
actions, such as mouse clicks and keyboard inputs.
- Load
testing: Load testing is a type of testing that checks how well the
software application can handle many users or transactions. Load testing
tools can automate the process of simulating thousands of users accessing
the application at the same time.
- Performance
testing: Performance testing is a type of testing that checks the speed,
scalability, and stability of the software application. Performance
testing tools can automate the process of simulating different load levels
to test the application's performance under different conditions.
Overall, software test automation can help to save time,
reduce costs, and improve software quality by identifying bugs and issues in
the software early in the development cycle.

testing: Regression testing involves testing the software after making
changes or modifications to the code. Automated regression testing can
help to quickly identify any defects or issues that may have been
introduced during the development process.
- Load
testing: Load testing involves testing the software's ability to handle many
users or transactions. Automated load testing can simulate thousands of
users accessing the application simultaneously, helping to identify any
performance or scalability issues.
- Cross-platform
testing: Cross-platform testing involves testing the software across
different operating systems, browsers, and devices. Automated testing can
help to streamline this process, ensuring that the software works
correctly on all platforms.
- Integration
testing: Integration testing involves testing how different components of
the software work together. Automated integration testing can help to
ensure that the software components are integrated correctly and function
as intended.

When should we go for Software Test
Automation ?
Answer :Software test automation can be a valuable
addition to a software testing strategy, but it is not always necessary or
appropriate in every situation. Here are some scenarios where software test
automation can be beneficial and when it may not be the best approach:
When to go for Software Test Automation:
- Large
or complex applications: For large or complex applications, manual testing
can be time-consuming and error prone. Automated testing can help to test many
scenarios more quickly and accurately, providing better test coverage.
- Repetitive
testing: Some tests, such as regression testing, require repeating the
same test cases multiple times. Automated testing can execute these tests
more quickly and consistently than manual testing, freeing up testers to
focus on more complex and exploratory testing activities.
- High-risk
areas: Some areas of the software, such as security or compliance, may be
high-risk and require more frequent and rigorous testing. Automated
testing can help to test these areas more thoroughly and consistently than
manual testing.

testing may not be able to keep up with the pace of development. Automated
testing can help to speed up the testing process, allowing for faster
release cycles.
- Resource
constraints: Organizations with limited testing resources may find it
challenging to conduct thorough manual testing. Automated testing can help
to make the most of available resources, allowing testers to focus on more
complex and critical tests.
When not to go for Software Test Automation:
- One-off
testing: For one-time or infrequent tests, the time and effort required to
develop and maintain automated tests may not be worth the investment.
Manual testing may be a more efficient and cost-effective approach in this
scenario.
- Exploratory
testing: Exploratory testing involves testing the software in a more
unstructured and informal way, allowing testers to explore the software
and identify potential issues. This type of testing is more difficult to
automate and may be better suited to manual testing.
- User
experience testing: User experience testing involves testing how users
interact with the software and can be challenging to automate. Manual
testing may be a more effective approach in this scenario.
- Early
development stages: In the early stages of software development, the

4.
Explain , Calculation ROI by going for test Automation?
Answer: Calculating the return on investment (ROI)
for test automation can help organizations determine whether it is worth the
investment. Here are the key steps to calculate the ROI of test automation:
- Determine
the cost of manual testing: The first step in calculating ROI is to
determine the cost of manual testing. This includes the cost of testers'
salaries, training, tools, and infrastructure required for testing.
- Determine
the cost of test automation: The next step is to determine the cost of
implementing test automation. This includes the cost of tools,
infrastructure, and the time and effort required to develop and maintain
automated tests.
- Calculate
the cost savings: The cost savings from test automation come from the
reduction in the time and effort required for testing. This includes the
time saved from executing automated tests, as well as the time saved from
identifying and fixing defects earlier in the development process.
- Estimate
the increase in test coverage: Test automation can help to increase test
coverage, which can reduce the risk of defects and improve software
quality. Estimate the potential increase in test coverage and factor it
into the ROI calculation.
- Estimate
the impact on software quality: Test automation can help to identify
defects earlier in the development process, reducing the cost of fixing
defects and improving the quality of the software. Estimate the potential
impact on software quality and factor it into the ROI calculation.
- Calculate
the ROI: To calculate the ROI, subtract the cost of test automation from
the cost of manual testing, and divide by the cost of test automation. The
resulting percentage is the ROI for test automation.
Here is an example of how to calculate the ROI of test
automation:
Assume that a software organization spends $100,000 per year
on manual testing, and it costs $50,000 to implement test automation. The
organization estimates that test automation will save them 50% of the time and
effort required for testing, increase test coverage by 25%, and improve software
quality by 10%.
The cost savings from test automation would be $50,000 per
year ($100,000 x 50%), and the potential increase in test coverage and software
quality would be worth an additional $20,000 per year ($100,000 x 25% x 10%).
The total cost savings and benefits from test automation
would be $70,000 per year. The ROI of test automation would be calculated as
follows:
ROI = (Cost savings + Benefits - Cost of Test Automation) /
Cost of Test Automation ROI = ($70,000 - $50,000) / $50,000 ROI = 0.4 or 40%
In this example, the ROI of test automation is 40%, meaning
that the organization would recoup their investment in test automation in 2.5
years. This demonstrates that test automation can be a valuable investment for
organizations that can benefit from the time and cost savings, increased test
coverage, and improved software quality.
5.

Development: In this phase, the team starts creating automated test
scripts based on the identified test cases. The testing team develops the
automation framework, test scripts, and identifies the test data and the
expected results.
- Test
Execution: During this phase, the automated test scripts are executed. The
testing team can execute the tests manually or use a test automation tool
to run the automated tests.
- Test
Reporting: Once the test execution is completed, the testing team
generates test reports that document the test results. These reports can
include details about the tests that passed, the tests that failed, and
the reasons for the failures.
- Test
Maintenance: In this phase, the testing team maintains the automated test
scripts by modifying them to accommodate changes in the software application,
requirements, or the test environment.
Here is an example of a test automation life cycle in
action:
Suppose a software development team is building a new
e-commerce website. The testing team starts the test automation life cycle as
follows:
- Test
Planning: The testing team reviews the project requirements and identifies
the scope of the project. They then develop a test plan and determine the
test cases that can be automated.
- Test
Design: The testing team creates a detailed test plan and identifies the
test cases that can be automated. They choose Selenium WebDriver as the
automation tool, Java as the scripting language, and create an automation
framework.
- Test
Development: The testing team develops automated test scripts based on the
identified test cases. They create test scripts to test the website's
navigation, search functionality, shopping cart, and checkout process.
- Test
Execution: The testing team uses Selenium WebDriver to execute the
automated test scripts. They run the tests against the website to verify
that it works as intended.
- Test
Reporting: Once the test execution is complete, the testing team generates
test reports that document the test results. They report on the tests that
passed, the tests that failed, and the reasons for the failures.
- Test
Maintenance: The testing team maintains the automated test scripts by
modifying them to accommodate changes in the software application,
requirements, or the test environment. They update the test scripts
whenever new features are added or when there are changes to the website's
functionality.
In summary, a test automation life cycle is a systematic process
that involves planning, designing, developing, executing, reporting, and
maintaining automated test scripts. By following the test automation life
cycle, testing teams can ensure that the automated tests are effective,
efficient, and provide accurate results.

Review: During Sprint Review, the team demonstrates the software to
stakeholders. Automated test results can be shared as part of the Sprint
Review to show that the software meets the acceptance criteria.
- Sprint
Retrospective: During Sprint Retrospective, the team reflects on the
Sprint and identifies ways to improve. The team can use the automated test
results to identify areas of the software that require improvement and
prioritize them for future sprints.
Here is an example of how test automation can be integrated
into Scrum:
Suppose a software development team is building a mobile
app. The team is following Scrum and has a two-week sprint. The testing team
decides to use Appium as the test automation tool and develops automated tests
for the user stories identified in the Sprint Planning phase.
During the sprint, the testing team runs the automated tests
using Appium on different mobile devices to ensure that the software works
correctly. The test results are automatically generated and stored in a test
management tool.
As part of the continuous integration process, the automated
tests are executed whenever new code is committed to the shared repository. The
test results are immediately visible to the team, and any issues identified can
be fixed promptly.
During the Sprint Review, the testing team shares the
automated test results with the stakeholders to demonstrate that the software
meets the acceptance criteria.
Finally, during the Sprint Retrospective, the team reviews
the automated test results and identifies areas of the software that require
improvement. They prioritize these areas for future sprints and plan to develop
additional automated tests to cover them.
In summary, test automation can be integrated into the Scrum
process to help teams deliver high-quality software quickly and efficiently. By
including test automation in the sprint backlog, developing automated tests in
parallel with software development, executing tests as part of continuous
integration, sharing test results with stakeholders during Sprint Review, and
using test results to identify areas for improvement during Sprint
Retrospective, testing teams can ensure that the software meets the acceptance
criteria and is delivered on time.

Explain Software Test Automation feasibility analysis
with score cards ?
Answer: Software test automation feasibility analysis
is a process of evaluating whether test automation is the right choice for a
particular software project. A feasibility analysis includes various factors
such as the complexity of the application, testing requirements, resource
availability, and ROI analysis.
To perform a feasibility analysis, we can use scorecards
that help us evaluate and compare different automation tools and techniques
based on various parameters. Here are some parameters that can be used in a
feasibility analysis scorecard:
- Application
complexity: The complexity of the application can impact the feasibility
of test automation. A simple application with few features may be easily
automated, while a complex application may require more effort and
resources.
- Testing
requirements: Testing requirements refer to the types of tests that need
to be performed, such as functional testing, integration testing,
performance testing, etc. Some tests may be easier to automate than
others, and this can impact the feasibility of automation.
- Tool
selection: The selection of the right automation tool is crucial for the
success of automation. Factors such as tool features, ease of use,
availability of support, and cost should be considered when selecting the
automation tool.
- Resource
availability: Resource availability includes the availability of skilled
personnel, hardware, and software required for automation. The
availability of resources impacts the feasibility of automation.
- ROI
analysis: ROI analysis helps us evaluate the return on investment for test
automation. It includes factors such as the cost of automation, the time
required for automation, and the benefits of automation such as increased
productivity, reduced testing time, and improved quality.
We can assign scores to each of these parameters based on
their importance to the project. For example, application complexity can be
given a score of 1-5, with 1 being the lowest complexity and 5 being the
highest. We can then multiply the score by a weight factor to calculate the
parameter score. For example, if application complexity is given a weight
factor of 0.3, and the score is 3, then the parameter score would be 0.9 (0.3 x
3).
Once we have scores for each parameter, we can add them up
to calculate the feasibility score for automation. For example, if we have
scores for all five parameters and the sum of all parameter scores is 3.5, then
the feasibility score would be 3.5 out of 5.
Using scorecards for feasibility analysis helps us evaluate
the suitability of automation for a particular project and helps us make
informed decisions. It also provides a structured approach to compare and
select automation tools and techniques.
An example of how a feasibility analysis scorecard can be
used to evaluate the feasibility of test automation for a sample project:
Parameter |
Score |
Weight Factor |
Parameter Score |
Application complexity |
4 |
0.3 |
1.2 |
Testing requirements |
3 |
0.2 |
0.6 |
Tool selection |
4 |
0.2 |
0.8 |
Resource availability |
3 |
0.2 |
0.6 |
ROI analysis |
4 |
0.1 |
0.4 |
Total Feasibility Score |
3.6 out of 5 |
In this example, we have assigned scores and weight factors
to five parameters: application complexity, testing requirements, tool
selection, resource availability, and ROI analysis. We have evaluated the
complexity of the application as "4", which is considered moderately
complex. We have assigned a weight factor of "0.3" to this parameter,
indicating that it has a high impact on the feasibility of test automation.
Multiplying the score by the weight factor gives us the parameter score of "1.2".
Similarly, we have evaluated the other parameters and
assigned scores and weight factors accordingly. Once we have calculated the
parameter scores, we can add them up to obtain the total feasibility score of
"3.6 out of 5". This score indicates that test automation is feasible
for this project, but there may be some challenges that need to be addressed.
Based on the feasibility score, we can decide whether to
proceed with test automation, and if so, what tools and techniques to use. We
may also need to address any challenges identified during the analysis to
ensure the success of automation.
12.

Explain Advantages and Disadvantages of Software Test
Automation ?
Advantages of Software Test Automation:
- Increased
Efficiency: Test automation can execute tests much faster and more
accurately than manual testing. This helps save time and resources and
increases the overall efficiency of the testing process.
- Improved
Test Coverage: Automation testing can execute many test cases in a
relatively short period of time, increasing test coverage and identifying
more defects in the software.
- Reusability:
Automated test scripts can be reused across multiple test cycles, reducing
the time and effort required to create new test scripts for each release.
- Consistency:
Automated tests are executed consistently each time, ensuring that the
test results are reliable and accurate.
- Cost
Savings: While there is an initial investment required for test automation
tools and resources, automated testing can ultimately lead to significant
cost savings in terms of time, resources, and overall testing efforts.
Disadvantages of Software Test Automation:
- High
Initial Cost: Test automation tools and resources can be expensive, which
may not be feasible for small projects or organizations with limited
budgets.
- Limited
Test Coverage: Automation testing can only cover tests that have been
scripted and may not be able to identify certain types of defects that can
be identified through manual testing.
- Maintenance:
Automated test scripts require regular maintenance and updates, which can
be time-consuming and require skilled resources.
- Lack
of Human Judgment: Automated tests lack human judgment and intuition,
which can be important in certain testing scenarios, such as usability
testing.
- Tool
Dependency: Test automation tools are often proprietary, and there can be
a dependence on these tools for test execution and reporting.
Examples: An example of the advantages of test automation is
illustrated in the case of a banking application. Suppose a banking application
needs to be tested for user authentication and transaction processing. Manual
testing would require a significant amount of time and resources to execute the
required test cases, and the results may not be consistent due to human error.
Automated testing, on the other hand, can execute the test cases much faster
and more accurately, leading to increased efficiency and improved test
coverage.
An example of the disadvantages of test automation is
illustrated in the case of a web application that needs to be tested for
browser compatibility. While automated testing can cover many browser and
operating system combinations, it may not be able to identify certain types of
defects that can be identified through manual testing. Additionally, automated
test scripts may need to be updated and maintained regularly to accommodate
changes in the web application or browser technology.

What are the best candidates for test
Automation and what shouldn't be picked for test automation ?
Best candidates for test automation:
- Repeated
Tests: Tests that need to be executed frequently, such as regression
testing or smoke testing, are good candidates for test automation.
Automated tests can be executed quickly and consistently, reducing the
time and effort required for manual testing.
- Large
Test Suites: Applications with many test cases can benefit from test
automation. Automated tests can execute many test cases in a relatively
short period of time, increasing test coverage and identifying more
defects in the software.
- Stable
Requirements: Applications with stable requirements are good candidates
for test automation. If the application requirements keep changing
frequently, automated test scripts will need to be updated regularly,
leading to more effort and time.
- Data-Driven
Tests: Applications with data-driven testing requirements, where test
cases need to be executed with multiple sets of data, can benefit from
automation. Automated tests can execute the same test cases with different
data sets quickly and accurately.
- Performance
Testing: Automated tools can generate many virtual users to simulate
real-life load scenarios for performance testing.
What shouldn't be picked for test automation:
- User
Interface (UI) testing: UI testing can be complex and requires the ability
to identify and deal with various UI elements. UI changes can also cause
false positives in automated tests, so manual testing is often preferred
in this case.
- Exploratory
Testing: Exploratory testing relies on human intuition and creativity,
which can't be automated.
- One-time
tests: Tests that need to be executed only once are not good candidates
for test automation. The effort required to create automated test scripts
for such tests may not be worth the benefits.
- Tests
requiring frequent updates: Tests that need frequent updates to keep up
with changing application requirements may not be good candidates for
automation. Constant updates to test scripts may lead to increased
maintenance costs.
- Tests
that require human judgment: Tests that require human judgment, such as
usability testing or visual testing, are not good candidates for
automation. Automated tools lack the ability to make subjective
assessments, so manual testing is often preferred in this case.
Example: Suppose a software application needs to be tested
for various scenarios related to user login, account creation, and transaction
processing. These tests can be repetitive and time-consuming if executed
manually. Hence, these tests can be automated, which will save time and
resources and increase the overall efficiency of the testing process. However,
exploratory testing, such as usability testing or visual testing, may require
human judgment, making them unsuitable for automation.
For example, in the case of usability testing, testers need
to interact with the software application and observe how it behaves in various
scenarios. The user interface of the application needs to be evaluated, and the
testers must assess whether the application is easy to use, navigate, and
understand. These types of tests require the use of human judgment and
intuition, making them unsuitable for automation.
Similarly, some one-time tests, such as testing a new
feature or verifying a bug fix, may not be suitable for automation. The effort
required to create automated test scripts for such tests may not be worth the
benefits of automation. Manual testing may be more efficient in such cases.
Tests that require frequent updates, such as tests related
to changing application requirements, may also not be suitable for automation.
If the requirements are continually changing, the test scripts will need to be
updated accordingly, leading to increased maintenance costs.
In summary, the best candidates for test automation are
tests that are repetitive, time-consuming, and require a lot of resources if
executed manually. On the other hand, tests that require human judgment,
creativity, or are one-time tests may not be suitable for automation. The
selection of the tests for automation should be based on the feasibility
analysis, considering the cost, effort, and benefits.
