14% Reliability issues: connection drop issuesover a period of time.

Load test at module level.

Scalability in terms of Number of usershandled by the system.

Quick comparison of Performance testresults across OS Platforms.

Load test at the functional level.

PSR testing for Quick POCs. (Based on survey conducted at BMC Software)

PROCESS

• Write code( 1- 6 months)

• Compile code

• Send it to QA (or Production ?)

• Performance Regression

• PANIC !

No Performance Testing !

A BETTER WAY

• Write code

• CI compiles code and runs test

• Send it to QA ( or Production?)

• Performance Regression

• PANIC !

No Performance Testing !

A BETTER WAY 2.0

• Performance test artifacts as soon as they pass Unit and Functional testing

• Fast feedback for developers

• No Surprises

Warm Up

• Performance testing• Agile methodology

• Automated testing

2/20/2010 First Draft 8

• To determine how fast some

aspect of a system performs

under a particular workload .

JMeter

• What is JMeter– Background– History

2/20/2010 First Draft 13

JMeter• Who can use JMeter

– Dev and QA

Using open source tools for performance testing Presenter: Goranka Bjedov

JMeter• Where can we use JMeter

2/20/2010 First Draft 15

JMeter• When can we use JMeter

- Know how the system responds to work load

- Pound system with simultaneous requests- Performance- Scalability- Reliability

– PSR tests on the quick POCs.

– Use in AGILE

– Use other tools that complement JMeter, e.g. Perfmon

Why JMeter

• Catch performance regressions quickly

• Simplify the hunting of bugs

• Code with confidence

• Know the performance cost of features

• Go home on time

It’s Demo Time

• JMeter and JUnit

• JMeter and database query testing

• JMeter and Web based Flex Performance testing

2/20/2010 First Draft 18

Performance Testing of Flex Web Application

• AMF - Action Message Format (AMF) binary format used to serialize ActionScript objects

• To performance test flex web app, need to generate required amf file first.

Distributed Testing

It’s your turn

• Performance testing

• Agile methodology

• Automated testing

2/20/2010 First Draft 21

Automated Testing

1. Integration with CI tools- Ant Target

- HTML Report Generation

Comparisons, Alternatives, Conclusions• Shortcomings of JMeter
