Manual Testing
Manual Testing is a process manually test the software to find the defect of the application.
It requires a tester to play the role of an end user and test all features of the application to ensure correct
behavior.
Tester need to write the test plans and complete the test with different test cases.

Manual Testing
Manually Loading 1000+ transactions
Validation of downloaded transactions
Create report for pass and fail transactions
Validation of form with multiple set of data – dataset
Take screenshot for each of the validation
Formatting of each and every process for SME review

Disadvantages Manual Testing
Manual Testing of all work flows, all fields , all scenarios is time and cost consuming, and required more resources
Scope of manual test is very limited
Executing same test case again and again is tedious task
Manual testing will be used when the test case only needs to runs once or twice
Simultaneously testing on different machine with different OS platform combination is not possible using manual
testing

Test automation
Test automation is the use of special software to control the execution of tests and the comparison of actual
outcomes with predicted outcomes.
 Optimization of Speed, Efficiency, Quality and the Decrease of Costs
 Advance a Tester´s Motivation and Efficiency
 Increase of Test Coverage
Why automate Testing?

Benefits of automated testing
 70% faster than the manual testing
 Wider test coverage of application features
 Reliable in results
 Ensure Consistency
 Saves Time and Cost
 Improves accuracy
 Human Intervention is not required while execution
 Increases Efficiency
 Better speed in executing tests
 Re-usable test scripts
 Test Frequently and thoroughly
 More cycle of execution can be achieved through automation
 Early time to market

When to use Test automation
 Regression Testing
 Smoke Testing
 Static & Repetitive Tests
 Task involves complex calculation
 Data Driven Testing
 Test Cases which are time consuming

 Application changing near to Future
 Test cases which are executed on ad-hoc basis.
When NOT to use Test automation

 HP Quick Test Professional
 Selenium
 IBM Rational Functional Tester
 Sikuli
 Silk Test
 Win Runner
 Load Runner
 Visual Studio Test Professional
 WATIR
Automation Testing Tools

Selenium is used to automate web applications across different platforms using different programming languages
This is one of the best tool for web applications
Performance and execution speed of selenium automation tool is much better than any automation tool which is
available in market because of its native support for browsers and also web Drivers operates on the OS lever
Selenium

 Supports almost every OS
 Open source
 Cost-effective automation testing
 Supports multiple programming language
 Independent of web Application programming language
 Supports multiple browsers
 More options to find an object
 Parallel execution
 Provides support for open source frameworks like TestNG, Junit
Features of Selenium

Test Execution Calculation
Automation Metrics
Test Script Preparation
Reliability Time to Market
Cross Browser

Cost Reduction
4000 Test Cases
4 Resources
Per resource = 1000
Per resource = 1000/40 =25 Days
4000 Test Cases
4 Resources
Per resource = 1000
Per resource = 1000/20 = 50 Days
Total = 4000
Day 1 = 24*60 minutes
Per script execution = 5 minutes
(60 * 9) / 5 minutes = 108 Test Cases / machine
(60 * 24 ) / 5 minutes = 288 Test Cases / machine
4 Machine = 288 * 4 = 1152 Test Cases
1152 * 4Days = 4608 Test Cases

Merged

Selenium WebDriver
 Selenium WebDriver is used to automate Web based applications on multiple platforms across different browsers
with different programming languages
 Selenium WebDriver is faster that RC because of its simpler architecture
Selenium 1.0 + WebDriver = Selenium 2.0

Selenium WebDriver
 WebDriver is simpler and more concise programming interface than Selenium-RC AP
 It is a compact Object Oriented API when compared to Selenium 1.0
 It interacts with browser directly while selenium RC need help of RC server to interact with browser which makes
it slow
 Selenium WebDriver overcomes the limitations of selenium 1.0, like file upload or download, pop-ups and dialogs
Barrier
 It overcomes the limitation of selenium RC single Host Origin Policy

Demo On Selenium Web Driver

Selenium Grid
Selenium-Grid allows us to execute Test Script on different machines at the same time (parallel execution) from
one system called Hub
Each machine is called node
That is, Selenium-Grid runs multiple tests at the same time against different machines running different browsers
and operating systems

 Parallel Execution
 Platform Independent
 Language Independent
 Browser Independent
 Fast Execution
Node 1: IE
on Windows
Node 2:
Android
Node 3: Safari
on MAC
Node 4: Firefox
in Ubuntu
Selenium Grid (Contd.)
