Most companies grasp the importance of leveraging test
automation to increase test coverage, reduce execution
time, and provide more frequent testing. But test
automation can be expensive. More than ever,
companies are seeking open source tools like Selenium
to reduce the cost. This case study demonstrates one
company’s experience using Selenium for test
automation.

Slide 5 Software Peace of Mind in Action
???
Needed a robust automation suite to perform “UI”
testing for integration/regression
Needed a subset of the automation suite (smoke test) to
run as part of Continuous Integration
Needed method for product owner, developers, and QA
to create automated tests
Needed to ensure maintainability of automated suite
Needed the automated suite to handle advanced and
dynamic web content
Case Study Background
Slide 6 Software Peace of Mind in Action
???
Selenium - Positives
FREE!
Supports multiple browsers
Scripts can be created with multiple programming
languages (Java, Ruby, Python, etc…)
Runs on Windows, Linux, and Mac
Not confined to the features of the tool
Integrates with other tools
Selenium vs. HP UFT

Slide 7 Software Peace of Mind in Action
???
Selenium - Downsides
Only supports web-based natively
No formal support (the user community provides
good feedback but questions are not always
answered)
Higher technical skillsets necessary to optimize the
Selenium framework
Reporting features are not as robust
Harder to find resources with both QA/testing and
Selenium experience
Selenium vs. HP UFT
Slide 8 Software Peace of Mind in Action
???
UFT - Positives
Established tool with wide usage
Supports multiple technologies (Web, Java, .Net,
SAP, Siebel CRM, PeopleSoft, Terminal Emulator,
etc.)
Has many built-in features (embedded data table,
smart identification, object configuration, object
repository, etc.)
Ease of use
Professional support, although room for improvement

UFT - Downsides
Cost! Purchase cost and yearly maintenance fees
Only supports IE and Firefox
Cannot run multiple instances on one machine
Selenium vs. HP UFT
Slide 10 Software Peace of Mind in Action
???
Cost
Alignment with the organization direction (most of the
development toolsets are open source)
Alignment with Agile methodologies
Ability to test on Mac
Ability to test on multiple browsers
Perception by both development and QA that Selenium
was easier to adapt
Factors in choosing Selenium

???
Logging file: The logging file will capture all the events
that take place in the Interpret Engine. This will help in
debugging the Interpret Engine
Reporting engine: The reporting will be created in html
format. The reporting can be set in two modes; info and
debug. In info mode, the html report will only report on
Verify Action. In debug mode, the html report will
contain all steps in the test case
Test Automation Implementation
Slide 20 Software Peace of Mind in Action
???
Automated 830 test cases
Integration level test cases with average of 38 steps/test
case
20 test cases are used for smoke testing by pairing with
continuous integration tool
Test cases are divided into three priorities (high, medium,
low)
Development and QA determine tests to run

Slide 21 Software Peace of Mind in Action
???
Execution of full automation suite takes around 3
hours using Sauce Lab
Manual testing would have taken 4 resources 40 hours to
execute the same suite
Maintenance of the suite, on average, is less than 8 hours
per execution
New enhancements for the automation framework
Data file will be replaced by database tables
A web UI will be created to make test case creation faster
A test execution scheduler will be created to manage off-
hour execution
Outcome of the project
Slide 22 Software Peace of Mind in Action
???
There are many benefits to leverage Selenium for test
automation. However, it is important to create a
detailed plan and roadmap to ensure success.
