JMeter load testing tool and Coldfusion

1. JMETER
The load testing tool
By : Pritesh Patel

2. WHAT IS LOAD TESTING?
 Load testing is the process of putting demand on a
system or device and measuring its response.
 Types of tests
 Performance Testing - is usually defined as the
process of exercising the system under test by feeding it
the largest tasks it can operate with
 Stress Testing - to break the
system under test by
overwhelming its resources
or by taking resources away
from it

3. WHY LOAD TESTING?
 Find Performance issue with your website
 Discover how many users your website support in
order to prevent disaster.
 Finding task which required performance
improvement.

4. HOW TO AVOID LOAD TESTING
 My client not ready to pay for testing?
 My manager has assign lots of work with very tight
deadline.
 I know there will be 2 to 3 users will visit this
application and server can handle that much load.

6. WHY JMETER?
 Can load and performance test many different server
types:
 Web - HTTP, HTTPS
 SOAP
 Database via JDBC
 LDAP
 JMS
 Mail - POP3(S) and IMAP(S)
 Full multithreading framework allows concurrent
sampling by many threads and simultaneous sampling
of different functions by seperate thread groups.
 Careful GUI design allows faster operation and more
precise timings.
 Caching and offline analysis/replaying of test results.

7. CONTINUE…
 Highly Extensible:
 Pluggable Samplers allow unlimited testing capabilities.
 Several load statistics may be chosen with pluggable
timers .
 Data analysis and visualization plugins allow great
extendibility as well as personalization.
 Functions can be used to provide dynamic input to a
test or provide data manipulation.
 Scriptable Samplers (BeanShell is fully supported; and
there is a sampler which supports BSF-compatible
languages)

8. INSTALLING JMETER (ON WINOW)
 Install Java (2.2. or higher)
 Download JMeter
http://jakarta.apache.org/site/downloads/index.html
 Add path of java installation in environment path
variables.

9. RUNNING JMETER IN WINDOWS
 Open command prompt (user administrative mode
to avoid unnecessary hassle).
 Traverse to [jmeter installation path]bin
 Run Jmeter.bat
If you are running test behind firewall try following
argument to pass with command prompt.
 -H [proxy server hostname or ip address]
-P [proxy server port]
-N [nonproxy hosts] (e.g. *.apache.org|localhost)
-u [username for proxy authentication - if required]
-a [password for proxy authentication - if required]

10. ELEMENTS OF TEST PLANS
 Thread Group
 Setup number of thread
 Set up ramp up period
 No. of times test exectues
 Controllers
 Sampler (Send Request to Server)
 Logical Controller (Customize logic to send request)
 Listener
 Graph Result
 View Results Tree and many more.
 Timers
 Delay next request for certain amount of time

11. CONTINUE….
 Assertions
 Allow you to assert fact about responses received from
HTTP request
 Configuration Elements
 Allow you configure settings
 Preprocessor
 Execute prior to sampler request
 PostProcessor
 Execute some action after sampler request

12. CREATING YOUR FIRST WEB TEST PLAN

13. ADDING USERS
 5 users send 3 requests on cfminds.com and
repeat it twice. (5 users x 3 requests x 2 repeat =
30 requests)
 Right click on test note >> Add >> Thread (users)
>> Thread Group

14. ADD DEFAULT HTTP REQUEST
 You can add default http request setting from ADD
>> Config Element >> HTTP request default.
 This will let you define default http parameter for
every request.

15. ADDING HTTP REQEST ELEMENT
 You can add it from ADD> Sampler >> HTTP
Request

16. ADDING LISTNER TO VIEW RESULT
 Listner responsible for storing all of the results of
our HTTP request and presenting in Visualize
mode.

17. DEMO

18. GRAPH COMPARISON (5 USERS VS 50
USERS)
5 Users
50 Users

19. 5 Users
50 Users

20. HTTP COOKIE MANAGER
 You can add cookie manager by right clicking on
test plan Add >> Config Element >> HTTP Cookie
Manager.
 Usage:
 Store and sends cookies just like browser
 Maintain separate cookie for each thread but share in all
requests.

21. LOGIN IN TO SECURE PAGES
 Find out action page of login form.
 Create HTTP Request Sampler and pass
username, password and other required data.
 Most important : Add HTTP Cookie manager if
session stores in cookie or depends on cookie.

22. DEMO

23. LOGIN WITH DIFFERENT USER IN EACH
THREAD
 Create CSV file with list of username and password
 Store in same folder where your test stores
 Add CSV Data set into your test tree from config
elements
 Add ${USER},${PASS} in request sampler as
parameter.

24. CONTROLLING REQUEST LOGIC
 Logic Controllers can be used to control flow.

25. DEMO

26. RECORDING YOUR TEST PLAN
 JMeter Proxy can use to record all request send to
server.
 Create test plan with default http testing
 Add HTTP Proxy Server in Workbench node.
 Define port# of proxy server
 Define URL Pattern to include/exclude
 .* - all
 .*/.cfm – CFM pages
 .*/.gif – GIF file etc.
 Start Proxy server.
 Setup Proxy server on your browser.

27. DEMO

28. JMETER DISTRIBUTED TESTING
 JMeter client machine may not able to simulate
enough users to stress server.
 Control multiple machine to run JMeter without
copying test samples to different machine.
 Configuration:
 Copy same version of JMeter to different computer.
 Add remote node IP in JMeter.proeprties file.
 Run JMeter on remote machine using
/JMETER_HOME/bin/jmeter-server (in command
prompt)
 Start JMeter GUI in host machine.
 Select any test plan.
 Go to Run >> Remote Start >> Remote IP Address.
