About the Presenter

"Well, yeah. There are questions and
answers. True or false, multiple choice,
essay. What's not to love?”

Automated
Testing Using
Selenium

We are here to talk about
• Testing
• Automation – Selenium Grid, Jmeter
• Selenium
• Continuous Integration/Continuous
Delivery/DevOps - Jenkins, FisheyeCrucible
and Sonarqube

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

Why is Testing Important?
• Software testing is any activity aimed at
evaluating an attribute or capability of a
program or system and determining that it
meets its required results
• Although crucial to software quality and
widely deployed by programmers and
testers, software testing still remains an art,
due to limited understanding of the
principles of software

Why is Testing Important?
• Software bugs can be very expensive and
Dangerous
• Software testing is important to deliver the
best possible application
• Current Methods:
o Manual
o 3rd Party Vendor Application

Testing - Impact
• We need an optimal amount of testing
based on the risk assessment of the
application
• Testing either too much or too little could be
costly for the company
• We need an optimal amount of testing
based on the risk assessment of the
application--over-testing or under-testing
are not recommended

Automation
• The difficulty with software testing stems from
the complexity of software:
o We can not completely test a program
with moderate complexity. Testing is more
than just debugging.
o The purpose of testing can be quality
assurance, verification and validation, or
reliability estimation. Testing can be used
as a generic metric as well.

Automation
o User Interface testing
• Simulate user actions
o Functional testing
• Create regression tests to verify
functionality and user acceptance
o Browser compatibility testing
• The same script can run on any
Selenium platform
o Load testing
o Stress testing

Automated Testing Using Selenium

Automation - Why
• There are many different devices, browsers,
and operating systems that could behave
differently when our websites/applications
are run on them
• Testing on multiple devices, browsers,
operating systems can help ensure our
website works for as many users as possible

Automation - Why
• Web apps usually deal with sensitive info,
e.g.
o Credit card numbers
o SSNs
o Billing / Shipping addresses
• Security one of the biggest concerns
• Security testing should simulate possible
attacks

Automation - Impact
• There’s always a chance that a user will do
what you least expect – no matter how
unlikely it seems
• Testing can uncover bugs, the tricky part is
figuring out where fixing bugs falls among
project management priorities
• Software testing is a trade-off between
budget, time and quality

Automation - Impact
• Software testing is important to deliver the
best possible application
• We owe it to our users and ourselves to
deliver the best applications possible
• Ultimately, we need software testing to
ensure our websites or apps are something
we can be proud of and have confidence
in

Automation - Impact
• Performance is crucial to the success of a
web application
• Performance testing evaluates system
performance under normal and heavy
usage
• Performance testing can be automated

What is Selenium
• What is selenium
• Chemical symbol - Se
• Atomic number - 34
• Atomic mass – 78.96
• Melting point – 428.9F
• Element classification – Non-Metal
• Crystal structure - Hexagonal

Selenium
• Jason Huggins and team from ThoughtWorks
Inc. developed the testing tool in 2004
• Huggins joked about competitor HP Mercury
tools saying to cure mercury poisoning by
taking selenium supplements

Selenium
• Selenium is an open source bowser based
test automation software
• Selenium is a robust suite of tools which
supports rapid development of test
automation for web-based applications
• Works anywhere Java script is supported
• Hooks for many other languages – Java,
Ruby, python

Selenium
• Selenium:
o Extensible framework
o Supports mobile testing Android/IOS
o Can write test cases using language of
choice Java, C#, Python, Ruby & HTML
o Supports native browser testing

• Selenium is a tool set that automates web
application testing across platforms
• Selenium can simulate user interactions in a
browser
• Functional testing
• Create regression tests to verify
functionality and user acceptance
• Browser compatibility testing
• The same script can run on any
Selenium platform

• Firefox extension
• Easy record and replay
• Debug and set breakpoints
• Save tests in HTML,
Web driver and other
formats.

• Selenium saves all information in an HTML table format
• Each record consists of:
o Command – tells Selenium what to do (e.g. “open”, “type”,
“click”, “verifyText”)
o Target – tells Selenium which HTML element a command refers
to (e.g. textbox, header, table)
o Value – used for any command that might need a value of
some kind (e.g. type something into a textbox)

• Selenium-Web driver
o Control the browser by programming
o More flexible and powerful
• Selenium-Web driver supports multiple browsers in multiple
platforms
o Google Chrome 12.0.712.0+
o Internet Explorer 6+
o Firefox 3.0+
o Opera 11.5+
o Android – 2.3+ for phones and tablets
o iOS 3+ for phones
o iOS 3.2+ for tablets

Pros of Selenium
• Possible to move testing from QA to Dev team
as part of unit testing
• Integration with most Continuous Integration
systems
• Easy to integrate test with development
language
• More control over the framework because of
language choices
• Possible to implement scalable testing using the
cloud/grid
• Faster execution

Cons of Selenium
• IE driver uses JavaScript simulated XPATH
• Scripts working in Firefox and Chrome may not work in IE
without some additional code
• No tools like Data Table for data driving test
• No Object Repository to store object mappings
• No object types in Selenium. Only Web Element and
Select
• Table and other common HTML elements need extra
code to work
• Different browsers may exhibit different issues on
operations
• Higher development effort for initial few months
• NOTE: Many of these Cons are more of minor technical
inconveniences than true “Cons”

DevOps
The DevOps approach seeks to meld
application development and deployment
into a more streamlined process, shifting some
of the operation team’s responsibilities back to
the development team in order to facilitate:
continuous development, continuous
integration, continuous delivery and
continuous monitoring processes

• Continuous Integration basically just means
that the developer's working copies are
synchronized with a shared mainline several
times a day

• Continuous Delivery is described as the
logical evolution of continuous integration:
Always be able to put a product into
production

• Continuous Deployment is described as the
logical next step after continuous delivery:
Automatically deploy the product into
production whenever it passes QA
