WebServices and Related Terms

In today's world, daily everyone is hearing terms like Web Service, XML-RPC, SOAP, SOA etc. So what are these things? Where we are using? How this is helpful in software applications?
Let's start a simple discussion here.


WEB SERVICE:
A webservice is nothing but some piece of software over internet / intranet without UI.
For example, I need a method to add 2 numbers. So I am developing a method "addNumbers" locally. But this method is in our local code and its complied as exe or JAR file, no others can use it if anyone wants the same functionality. 
If I published this method in common repository, anyone can use by knowing this method signature and how to access them. This is webservice. 
- WebService can be published on internet or intranet. 
- Its language independent. ie. WebServices can be written in any language and accessible from any language.
- Platform Independent ie. published on any webserver and accessible from any OS.
- No need of UI technologies, only service through TCP/IP over HTTP.
Ex.
Displaying weather reports on different sites, World Clocks, etc.


COMPONENTS OF WEBSERVICE:
There are 3 components which are making a webservice.
1. Service Provider
Service Provider is a WebService published on internet or intranet to access from public.
Ex. PayPal Gateway


2. Service Consumer
Service Consumer is service which is requesting to access the published webservice.
Ex. Any Train, Bus booking site


3. Service Registry
Service Registry is nothing but a WebServer or Web Application server in which we will publish our WebServices to reside.
Ex. Servers like IIS, TomCat, etc.


Then, What is XML-RPC, SOAP, WSDL, UDDI, SOA?
For any WebService we need 3 tasks like data transmission, then some task to describe our webservice to access from public and then some task to make our Webservice discoverable, how to discover etc from public.


Message Formats:
Currently developers are using XML based data formats majorly. So these kind of messages are transported over HTTP (Also we can do over SMTP or FTP)
1. XML-RPC (XML based Remote Procedure Call)
This is pure XML format message which will be sent to access a WebService and again the response will come  in XML format.
2. SOAP
This is another format based on XML structure. SIMPLE OBJECT ACCESS PROTOCOL is a custom message format to send request for a webservice and reponse also will co,e in SOAP format.
3. JSON
JavaScript Object Notation is also another message format in name-value pairs. Its rising today as it is easy of use format interns of code.


Description:
This is the way to describe our published webservice like API method name, parameters etc.
1. WSDL
Web Service Description Language is used widely to describe any webservice. This .wsdl contains your method signatures. This WSDL is developed by MicroSoft and IBM.


Discoverable and Discovery:
This is the way to make our webservive discoverable across public and how to access this webservice.
1. UDDI
Universal description and discovery Integraion is used widely to publish Webservices through publish and find mechanisms. Its a public webserver where you can deploy your webservices. Normally gov sites will use more.


Then, SOA is a wide topic to design applications. Service Oriented Architecture design is a approach where business functions of applications are designed as webservices and UI is used to represent the data only. (Just like database driven applications where stored procedures will do all functions and UI is used to display the data and interactions.)


So normally, for these kind of applications QA people will do lot of WebServices testing and minimum level of testing from UI.

JMeter - Beginner's Tutorial

This is a basic tutorial explains how to start with JMeter and how to use for basic load testing. Also it covers a flow which is mostly used across industries.
You can get lot of clear help here. JMeter Help

JMeter supports HTTP, HTTPS, FTP, SOAP and LDAP and it can be Integrated with selenium to do extensive use. Here are the flow to start your Load Testing.


Creating Tests:
1. First, Add Proxy (Under Workbench >> Non-Test Elements). This Proxy only acts as a recorder.
So don't forget to start the proxy before recording. Also after finished recording, stop the Proxy.


2. Add Controller. (Under Workbench >> Logic Controllers >> Simple Controller). This Controller is nothing but a container(mainly used for grouping). Inside a controller you can have your requests. ie. Transactions


3. Now record your transaction and drag it under your controller.


4. Add ThreadGroup (Under TestPlan) and group the recorded requests(or controllers) under thread group. Its for grouping set of controllers to run. ThreadGroup will contain users, ramp up and etc which are used to virtualize load while running.


5. Add listeners. (Workbench >> Listeners >> Assertions >> Comparison Assertion Visualizer). Listeners are needed to RUN, otherwise you can't view the results. Listeners are like runner here. You can select any kind of listener based on requirement.
Comparison Assertion Visualizer  -- will show results pass or fail for each request.
Save Response to File  -- will save response to external html file.


Assertions:
6. Add assertions for specified request. (Ex. Response Assertion is used to verify some text is present or not).
That's all. Now script is ready. So lets start your load test now.


Running:
1. Go to your Thread Group
2. Set No.Of. Threads(Users)Ramp Up Period and Loop Count.
3. Start Run and see the results on your listener.


Data-Driven:
We can feed data from CSV file or extract data from previous response and feed that to a request.


7. We can feed data from CSV file.
     - Just keep a CSV file with only data but not with column names.(separated by any delimiter)
     - Add "Config Element >> CSV Data Set Config"
     - Set FileName and ColumnNames (CSV contains no column names, just data. So you need to mention your column names ie.Variable Names here separed by delimiter)
     - On Request, Pass value as ${VariableName} ie. Column Names specified in above step.


8. Data Correlation ie. Extract data from previous page's response and put it as data for next request or page transaction.
    - Do "Listeners >> Save Response to file" for previous request.
    - Then find the format of expression in response for the part containing our data to be extracted.
    - Then on the request, add "Post Processors >> Regular Expression Extractor" to extract the data.
    - Set Reference Name, Expression (like productID=(.*?) ) and template as $1$ (template is used to extract multiple values. Here going to extract 1 string only. If its two values, then $1$$2$)
   - Then for the next request, set this reference name as value like ${refName}

Hope this discussion will give you some idea on how to work with JMeter !!!

Cloud Computing Vs SaaS, PaaS and IaaS

Lot of peoples have some confusions about what is Cloud? If so then what is SaaS?
I will discuss about this topic with information I have.


Basically Cloud Computing refers some computing operation over internet, it may be any kind of service. Under this we have different models according to industry requirements. They are,
  1. Software as a Service
  2. Platform as a Service
  3. Infrastructure as a Service
Software as a Service - SaaS:
 SaaS refers simply access to an software application via internet on our client browser or any kind. It may be any kind like hosted in own environment or hosted in third party environment. 
Its related directly to end users.
Ex. Gmail, Google Docs etc.

Platform as a Service - PaaS:
PaaS refers access to a platform that provides capabilities to develop and test software applications via internet.
Its related to developers and testers who creates the software application.
Ex. Force.com(by SalesForce.Com), Google App Engine, Windows Azure, etc.

Infrastructure as a Service - IaaS:
IaaS refers access to hardware like mail servers, web servers etc via internet.
Its related to IT persons(or Organizations) who is responsible to provide environment for developers and testers to make software application.
Ex. Amazon EC2, Database.com(by SalesForce.Com), RackSpace, etc.


Hope this article will give you some ideas !!!

Mobile Testing - Kinds of testing carried out on a Mobile app

In today's world, without mobile (especially Smart Phone) nothing moves for every one. As mobile phone users are growing well, mobile market is on the boom. Obviously Mobile testing is an important area for today's software testers.
So how to start mobile testing? What kinds of testing will be carried out on a mobile application?


Basically 4 types of mobile application is there.
1. Native application (Installable / Un-Installable)
2. Native application (Not Installable / Un-Installable, comes with device)
3. Web application (optimized with m.domain.com)
4. Applications work using WAP


So, have to execute many type of testing based on the application area, domain etc. This document will give you all kinds of testing. You can execute all or selective tests for your mobile application.
http://unifiedtestinginitiative.org/files/utc_android_v1.pdf


As we know, lot of automation tools supporting mobile testing. Something,
1. QTP
2. TestComplete
3. SeeTest Studio
4. Keynote DeviceAnyWhere
5. TestDroid by BitBar
6. M-eux by Jamo Solutions (Add-On for QTP, Visual Studio and Eclipse)
7. iPhoney
8. iPad Peek etc.
9. Selenium with FoneMonkey by gorilla
10. Selenium android driver
11. Perfecto Mobile providing some solutions
You can look here for more. More mobile testing tools


Lot of frameworks and approaches are followed in today's world to carry effective automated mobile testing on android, iOS, Blackberry, Windows Mobile OS, etc. 
For Android,
1. Selenium android Webdriver - OpenSource and works with ADT plug-in for eclipse
2. Robotium - Opensource and have extra features for mobile testing. We can also use ADT plug-in here.


Also I want to list some discussions which will give you real time problems on mobile application.

Continuous Integration vs Version Control

Most of new techies have a doubt on What is Continuous Integration? and What is Version Control? What's the relation between them? 
I want to explore and discuss something about this topic here.


Actually Continuous Integration(CI) is more than Version Control (VC). Version control is simply for maintaining different version of docs or files while users committing changes to common repository. But CI is far more than that. CI is fully related to automation  o application build and deployment activities.


Continuous Integration:
CI is a system which is used t automate our building and deployment process. At any time, the executable are ready (to test or to production) with workable condition. It includes,

1. Maintain a code repository
Common shared repository to maintain code. Actually its Version Control system.


2. Automate the build
Using available code in common repository, system will do building process to generate executable. This building process will be done automatically.


3. Make the build self-testing
While doing building process, system itself will check for errors and warnings in build process.


4. Everyone commits to the baseline every day
All available stakeholders will commit their part of code changes every day or as soon as possible after doing changes so that it will not affect the full application. Also if your changes are conflict with repository copy, then it wont allow you to commit unless you get latest, do changes and commit.


5. Every commit (to baseline) should be built
For each and every committing done by users, the build process will be triggered.


6. Keep the build fast
Building process will be fast enough as every day code changes are committed and no major changes will not be there. This will avoid unnecessary ambiguities in code.

7. Test in a clone of the production environment
As we have working software deliverable ready all the times, we can test using the clone of latest executable. This will ensure quality confidence on changes made in new build.


8. Everyone can see the results of the latest build
Everyone can know the status of latest build. If any errors or warnings while building, system will report the errors to all stake holders.


9. Automate Installation / Deployment
As we have latest build for each day, we can automate the deploying processes. This will ensure the latest application build is up for testing on each day.


Version Control:
VC is a system which provides a shared repository to your code and maintains the changes by keeping the different version of file.


CruiseControl, Hudson, teamcity, Bamboo, etc. are CI tools.
SVN, Visual SourceSafe, Git, etc are Version Control tools.
Maven, ant are build tools.


Hope this will you some ideas about CI and VC.
