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

• f developed computer software. It includes

a set of activities conducted with the intent

• f 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:
• Manual
• 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:

• We can not completely test a program

with moderate complexity. Testing is more than just debugging.

• 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

• User Interface testing
• Simulate user actions
• Functional testing
• Create regression tests to verify

functionality and user acceptance

• Browser compatibility testing
• The same script can run on any

Selenium platform

• Load testing
• Stress testing

Manual test VS Automated test

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,
• perating systems can help ensure our

website works for as many users as possible

Automation - Why

• Web apps usually deal with sensitive info,

e.g.

• Credit card numbers
• SSNs
• 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:
• Extensible framework
• Supports mobile testing Android/IOS
• Can write test cases using language of

choice Java, C#, Python, Ruby & HTML

• 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:
• Command – tells Selenium what to do (e.g. “open”, “type”,

“click”, “verifyText”)

• Target – tells Selenium which HTML element a command refers

to (e.g. textbox, header, table)

• Value – used for any command that might need a value of

some kind (e.g. type something into a textbox)

• Selenium-Web driver
• Control the browser by programming
• More flexible and powerful
• Selenium-Web driver supports multiple browsers in multiple

platforms

• Google Chrome 12.0.712.0+
• Internet Explorer 6+
• Firefox 3.0+
• Opera 11.5+
• Android – 2.3+ for phones and tablets
• iOS 3+ for phones
• 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
• perations
• 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

• f 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
