 Q & A
ON SCREEN EXAMPLE
PERFORMANCE TESTING
 WHAT?
 A non-functional testing technique
 Determines the system parameters in terms of responsiveness, speed, stability, throughput
and reliability under various workload
 Uncovers what needs to be improved before the product goes to market
 WHY?
 Does the application respond quick enough on several users?
 Does it meet client requirements
 Will it bear expected user load or beyond load?
 Search results example
 WHICH?
 Always done for client server based systems only
TYPES OF PERFORMANCE TESTING
 LOAD TESTING - measures the system performance based on a volume of users.
 STRESS TESTING – measures application under extreme workloads, measure the breakpoint of a
system
 ENDURANCE TESTING – measures application can handle the expected load over a long period of
time.
 SPIKE TESTING – measures how the system behaves under unexpected heavy load conditions, and
its ability to recover.
 VOLUME TESTING – measures performance under varying database volumes
 SCALABILIT TESTING - measures the software application's effectiveness in "scaling up" to
support an increase in user load. Helps plan capacity addition to your software system.
MANUAL TESTING LIMITATIONS
 Expensive
 Time consuming
 Not Availability of man power and machinery
 Complicated in terms of Concurrency
 Inaccurate or probabilistic results
LOAD TESTING TOOLS
 HPE - LOADRUNNER
 IBM - RATIONAL PERFORMANCE TESTER
 APACHE - JMETER
 SMARTBEAR - LOAD COMPLETE
 NEOTYS - NEO LOAD
 BLAZE METER
 WAPT
 VISUAL STUDIO PERFORMANCE TESTER

LOADRUNNER?
 An automated solution by HP now Micro focus.
 Founded in April 2000
 Latest version 12.55
 Replaces human users with virtual users (Vusers)
 Creates peak and controlled load situations
 Reduces hardware requirements
 Controls from a single component
LR COMPONENTS
 VUGEN
 Records and edits Vuser scripts
 CONTROLLER
 An administrative center for creating, maintaining, and executing
Scenarios
 LOAD GENERATOR
 Generates the load against the application by following scripts
 ANALYSIS
 Assembles logs from various load generators and formats reports for
visualization of run result data and monitoring data.
