----------------------------------------------
i What is Performance Testing?
It is a Test Type,
Basically Software Testing is two types,
1 Functional Testing
2 Non Functional Testing
Functional Testing
Checking the Functionality of the System /AUT
Non Functional Testing
Checking Quality Attributes of the System / AUT
Quality Attributes:
Performance (Load, Stress, Spike, Endurance etc...
Usability,
Recovery,
Compliance
Localization,
Internationalization etc...
----------------------------------------------
ii Functional Testing vs. Performance Testing
Functional Test Requirement: Login to xyz Application
Functional Testing:
Positive Scenario:
1 Login to xyz Application using valid user name and valid password
(Expected: Application Home Page
Negative Scenario: Login to xyz Application with invalid input, Expected: Error Message
1 Login to xyz Application with invalid user name and valid password
2 Login to xyz Application with valid user name and invalid password
3 Login to xyz Application with invalid user name and invalid password
4 Login to xyz Application with blank user name and valid password etc...
Performance Test Requirement: Login to xyz Application with multiple users load.
Performance Testing:
1 Login to xyz Application with increasing users load 2000, 3000, 4000.... - Load Testing
Expected: Login Time for multiple users 6 seconds
2 Login to xyz Application with maximum load/more than the capacity 10000, 11000... - Stress Testing
3 Login to xyz Application with sudden increments/decrements 1000, 9000, 1500... - Spike Testing
4 Login to xyz Application with multiple users over a period of time - Endurance Testing
(5000 user load for 2 hours/repeate Login operation for 5000 users for 2 hours of time -
----------------------------------------------
iii How to conduct Performance Testing?
Generally, Software Testing can be done in two ways,
1 Manual Testing
2 Automated Testing
Ex: We can conduct Functional Testing manually or using any Test Tool like UFT or Selenium etc...
But Manual Testing is impractical for Performance Testing.
Popular test Tools for Performance Testing,
LoadRunner - Commercial Tool
JMeter - Open Source Tool
RPT - Commercial Tool
SilkPerformer - Commercial Tool
WebLoad etc...
----------------------------------------------
iv Performance Test Process -Automated Test Process
Important Steps:
Setup Test Environment
Create Test Script and execute it once.
Create and apply multiple user (Virtual users load
Run Load scenario/s
Analysis -Analyze the Test Result
