4. Agenda
• SOA
– Introduction
– Web Services
– Testing Aspects
• SOAP web services
– Introduction
– Testing
• RESTful web services
– Introduction
– Testing
• SoapUI
– Features
– Demo

5. Agenda Contd…
• Automation
– Custom clients in Open & Microsoft
Technologies
– To automate – Issue Tracking System, TCM, CI
etc.
• Demos
– Create a test case using SoapUI & Integration
test
– Create a test case using WCFClient
– Write a simple client in C# using Visual Studio
– Write a simple client in Java using Eclipse

6. What is SOA?
• Service Oriented Architecture (SOA) is a
software design pattern or philosophy
• Distinct and loosely coupled software pieces
(called services) encapsulating business logic
providing application functionality
• Client (Service Requester)  Server (Service
Provider) model
• Independent of any vendor, product or
technology
• Reference -
http://en.wikipedia.org/wiki/Service-oriented_
architecture

7. SOA Elements

8. SOA Principles
• Loose coupling
• Contract
• Abstraction
• Autonomy
• Reusability
• Statelessness
• Discoverability
• Composability
• Etc..

9. What is a Service?
• Services are unassociated, loosely coupled
units of functionality that are
– self-contained
– Self-describing
• Well defined interface/contract using
standard protocols
• Independent of any technology or vendor

10. What is a Web service?
• Service which communicates over the
internet or www
• Has API with web methods / operations
• Uses web standards like,
– XML/JSON for defining
• Interface/Contract
• Message architecture & format
– HTTP(s) protocol for communication

11. SOA Examples
• Examples,
– Websites like Portals or Mashups
– Payment Gateways
– Mobile application clients
• Composed of,
– in-house (different department)
– third-party (different vendor)
– public services (government etc.)

12. SOA Testing Challenges
• No User Interface
• Heterogeneous
– Variety of service types, implementation &
technologies
• Third-party service so no control
• Isolation of defects
– Whose responsibility? Provider? Requester? Both?
• How do you know vendor has tested the
service thoroughly?
• If we are a provider, how do we show that it is
worthy of acceptance?

13. SOA Testing Aspects
• Everything has to be tested
– End-to-End
– Service-by-Service
– Interface-by-Interface
– Process orchestration
• End-to-End
– User-Interface testing
• Service Testing
– Functional
• Contract/API
– Non-functional
• Security
• Performance

14. SOA Testing Aspects
• Practices & Techniques
– Continuous Integration & Deployment
– Service virtualization / Mocking
• Test Management
– Framework
– Regression
– Reporting

15. Web Service Types
• SOAP / WSDL
– Simple Object Access Protocol
– Web Services Description Language
• REST / WADL
– Representational State Transfer
– Web Application Description Language
• Others
– XML/JSON-RPC

16. SOAP
• Simple Object Access Protocol
• Interface  Endpoint(s), Operation(s)
• Message format  XML
• Transport  HTTP or others
• WSDL – Web Services Description
Language
– Machine readable
– Automatic code generation (Proxy)

17. SOAP Example
• IP2Geo
– Service
• http://ws.cdyne.com/ip2geo/ip2geo.asmx
– Request-Response
• http://ws.cdyne.com/ip2geo/ip2geo.asmx?
op=ResolveIP
– WSDL
• http://ws.cdyne.com/ip2geo/ip2geo.asmx?wsdl

18. SOAP Testing
• Testing a SOAP API means manipulating a
request XML and interpreting a response
XML

19. SOAP Testing Tools
• IDE Tools
– Eclipse Web Service Explorer
– WCFTestClient from Visual Studio
• Web-based
– http://wsdlbrowser.com
– http://www.soapclient.com/soaptest.html
• Browser Apps
– Firefox - SOAPClient
– Chrome – wizdler

20. SOAP Testing Tools
• Custom
– Eclipse/Java – Web service client / soap-ws,
Junit
– VS/.NET – Service/Web Reference, Nunit
– Perl – SOAP:Lite, PerlUnit
– Language – {SOAP Library / Proxy code},
{xUnit}
• Specialized
– SoapUI (http://www.soapui.org)
– SoaTest (http://www.parasoft.com/soatest)

21. Q&A?

22. REST
• Representational State Transfer
• Architectural style
• It is NOT a protocol like SOAP. Protocol is HTTP.
• HTTP operations
– GET, POST, PUT, DELETE, TRACE, HEAD, OPTIONS
• Endpoint  Resource
• Operations on resource
– Create  POST
– Retrieve  GET
– Update  PUT
– Delete  DELETE

23. REST constraints
• Use HTTP methods explicitly
• Be stateless or Idempotent
• Expose directory structure-like URIs
• Transfer XML, JavaScript Object Notation
(JSON), or both
• Etc.

24. REST API Examples
• Twitter: https://dev.twitter.com/rest/public
• Flickr: http://www.flickr.com/services/api
• Google -
https://developers.google.com/maps/docum
entation/timezone/
– Example – Current Time Zone
• Amazon S3 -
http://docs.aws.amazon.com/AmazonS3/late
st/API/APIRest.html
• http://www.thomas-bayer.com/sqlrest/

25. REST API
• Endpoint – Root of API
• List of Resources in a hierarchical manner
– /api/customers/
– /api/customers/1
– /api/customers/1/zipcode
• For each resource
– List of HTTP methods: GET, POST, PUT, DELETE
– For each method
• List of Headers
• Request JSON/XML for POST/PUT
• Response JSON/XML

26. REST Misc
• Sample WADL
• REST APIs are generally not open and
require some kind of authentication
– Basic HTTP authentication
– API Key (linked to an account, eg. Google)
– OAuth
• Further
– XML/JSON processing for verification
– Regular expressions

27. REST Testing
• Testing a REST API means manipulating
the request URI and interpreting the answer

28. REST Testing Tools
• Desktop tools
– https://github.com/wiztools/rest-client
• Command Line tools
– cURL
• Online Tools
– http://apikitchen.com/
– http://hackst.com/
– https://apigee.com/console
• Browser apps
– Firefox – REST Client
– Chrome – Advaned Rest Client

29. REST Testing Tools
• Custom
– Perl – REST::Client, PerlUnit
– Java – Apache HttpClient, JUnit
– Language – {Http library, REST client library},
{xUnit}
