4. Agenda
● Advantages of using tools for SOA testing
● Choosing the right tool that matches your requirement
● Test Scenarios
- soapUI
- Apache JMeter
● Tips on tools

5. Advantages of using tools & automation for testing
● No need to re-invent the wheel : Reduce time of writing
client programs from scratch
● Reduces time on frequent recursive testing
● Saves time to utilize the specialized knowledge effectively;
i.e. to do exploratory testing
● Reduces test execution time : Takes more time if done
manually
● Helps to release early & release often
● Reduces the possibility of missing test scenarios
● Ability to do dynamic data driven testing

6. Advantages of using tools & automation for testing
Contd...
● Ability to do load/performance testing
● Can generate result summaries and reports easily
● Ability to integrate test suites in build systems and trigger
automatically

7. Choosing the right tool...

8. soapUI - What does it support?
● Automated request generation : i.e. Generate SOAP
request messages when WSDL is provided
● Ability to validate responses : i.e. assertions
● Support for QoS : i.e. Security, MTOM
● Ability to simulate service providers; i.e. mock services
● Ability to do performance testing
● Supports multiple protocols & message types : i.e. HTTP,
HTTPS, REST, JMS, JSON

9. Examples with soapUI
● Web Testcase support
● Invoking secured web services with HTTP basic
authentication
● Invoking a web services secured with asymmetric binding
policy
● Assertions for responses
● Sending HTTP chunk encoded messages
● Executing soapUI test suites/test cases in headless mode
● Testing RESTful APIs

10. Web Testcase support
● Allows to test solutions without ?wsdl
● Invoke simple HTTP methods; i.e. GET, POST, etc on
different services within the same project.

11. Basic Authentication
An example
Service Provider
Service Consumer
Service A
Service B
<GET https://192.168.217.1:
9443/services/HelloService/greet?name=SoapUI
HTTP/1.1
Accept-Encoding: gzip,deflate
Authorization: Basic ZXZhbjplZWVlZWU= Service C
Host: 192.168.217.1:9443
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.1.1 (java 1.5)

12. Signing SOAP messages
● Asymmetric binding
- message security is provided using asymmetric keys
E.g.: public keys.
Client signs the message from his private key and
encrypts from server's public key
Server signs the message from his private key and
encrypts from client's public key Server's Client's
Client's Server's
public key private key public key
private key
- assures confidentiality, integrity and the non-repudiation

13. Increase raw request/response size
When raw view does not show large messages,
configure UI settings ...
... and it will increase
- size of raw request messages
- size of raw response messages

14. Assertions
● Validates responses
● Added to test steps
● Provides different types of assertions; assertions to be
done on response message, for HTTP status codes, SOAP
faults
Add Assertions

15. Sending chunked-encoded requests
● Content-Length
- The length of the request body in octets
POST /services/Axis2Service HTTP/1.1
Accept-Encoding: gzip,deflate
Content-Type: text/xml;charset=UTF-8
SOAPAction: "urn:echoInt"
Content-Length: 3782
Host: 127.0.0.1:9764
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.1.1 (java 1.5)
● Chunked
- Messages are sent in chunks
POST /services/Axis2Service HTTP/1.1
Accept-Encoding: gzip,deflate
Content-Type: text/xml;charset=UTF-8
SOAPAction: "urn:echoInt"
Transfer-Encoding: chunked
Host: 127.0.0.1:9764
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.1.1 (java 1.5)

16. Headless mode compatibility of soapUI
● Windows
○ testrunner.bat -s Axis2Service_TestSuite -r -f C:soapUIlogsresponse -I
C:soapUIprojectsmy_soapui-project.xml
● Linux
○ testrunner.sh -s Axis2Service_TestSuite -r -f /opt/soapUI/logs/response -I
/opt/soapUI/projects/my_soapui-project.xml
● Parameter list
s the test suite to run
c the test case to run
r prints summary report
l ignore errors and continue
f folder to which test results should be saved

17. Testing RESTful APIs
● Scenario 1 - Invoke Login API of WSO2 API Manager

18. In which situations we can use JMeter?
● To simulate multiple user access/ load tests
● For data driven testing
● To analyze & measure performance of services
● To validate responses; i.e. assertions
● To create test suites with real world scenarios which involves
executing multiple services sequentially or in parallel
● Support for different transport protocols; i.e. HTTP, HTTPS,
JMS, MAIL, FTP, JDBC, LDAP etc

19. Testing examples with JMeter
Scenario 1 : Testing a web service with dynamic data
1. Send SOAP requests to a Stock Quote web service
2. Need to send dynamic data inputs in the SOAP request
3. Read the response and verify the response is valid
1. Send request to the Web Service
2. Send requests with dynamic inputs
Stock Quote
service
(Currency conversion rate)

20. Testing examples with JMeter
Scenario 1 : What JMeter components you will need?
● Thread Group
● Sampler > SOAP/XML-RPC Request
● Config Element > CSV Data Set Config
● Assertions > Response Assertion
● Listener > View Results Tree
● Listener > Aggregate Report

21. Testing examples with JMeter
Scenario 2 : Testing API's with WSO2 API Manager
1. Call the login API [REST] and acquire an access token
2. Use that access token to invoke the API
3. Read the response and verify the response is correct
1. Invoke Login API
Login API
(Access Token)
2. Invoke Stock Quote API with the Access Token
Stock Quote
API
(Response)

22. Testing examples with JMeter
Scenario 2 : What JMeter components you will need?
● Thread Group
● Config Element > HTTP Cookie Manager
● Config Element > User Defined Variables
● Sampler > HTTP Request
● Config Element > HTTP Header Manager
● Post Processors > Regular Expression Extractor
● Assertions > Response Assertion
● Logic Controller > Loop Controller
● Listner > View Results Tree
● Listner > Aggregate Report

Dem

23. Testing examples with JMeter
Scenario 3 : Running JMeter scripts in 'Headless' mode
● Create it once.... Run it anywhere!!!
● All you need is a JMeter distribution a JRE installed and a
command shell
● Linux : ./jmeter.sh -n -t /path/to/JmeterTest.jmx -l /path/to/resultsFile.jtl
● Windows : jmeter.bat -n -t pathtoJmeterTest.jmx -l pathtoresultsFile.jtl
● Use Shell/ Batch scripts to change test parameters and execute
programmatically, for recursive test scenarios.

24. Tips...
When sending http requests with Jmeter always select
'httpclient4' as the implementation for high load scenarios
When doing load tests disable "View Results Tree", as it
affects thread creation rate.
Always keep test parameters like endpoints, IPs, ports etc as
configurable variables
For high load tests run the Jmeter tests in headless mode, and
write the result to a .jtl file. You can open them later in JMeter
UI, to check results summary, and performance figures.
When measuring performance figures with load tests make sure
only the client and server are running in their respective
machines

25. Tips...
Other free external plugins are available for Jmeter
● Ant plugin http://www.programmerplanet.org/pages/projects/jmeter-ant-task.php
Allows you to run JMeter script as an ANT task
Creates reports
● Google plugin http://code.google.com/p/jmeter-plugins/
Generates new set of graphs for performance test
Have some new throughput controlling components
