How Can a Website Be Tested?

Points to be considered while testing a Website:

Websites are essentially client/server applications – with web servers and ‘browser’ clients.

Consideration should be given to the interactions between HTML pages, TCP/IP communications, Internet connections, firewalls, applications that run in web pages (such as applets, javascript, plug-in applications) and applications that run on the server side (such as CGI scripts, database interfaces, logging applications, dynamic page generators, asp, etc.).

Additionally, there are a wide variety of servers and browsers with various versions of each. They include small but sometimes significant differences between them in terms of variations in connection speeds, rapidly changing technologies, and multiple standards & protocols. The end result of which testing for websites can become a major ongoing effort.

Other considerations include

Few other considerations to be included while testing a website are given below.

  • What is the expected load on the server (e.g., number of hits per unit time)?
  • What kind of performance is required under each load condition (such as web server response time, database query response times)?
  • What kind of tools will be required for performance testing (such as web load testing tools, other tools already in house that can be adapted, web robot downloading tools, etc.)?
  • Who is the target audience? What kind of browsers will they be using? What kind of connection speeds will they be using? Are they intra- organizations (thus likely with high connection speeds and similar browsers) or Internet-wide (thus with a wide variety of connection speeds and browser types)?
  • What kind of performance is expected from the client side (e.g., how fast should pages appear, how fast should animations, applets, etc. load and run)?
  • Will the downtime for server and content maintenance/upgrades be allowed? If so, then how much?
  • What kind of security (firewalls, encryption, passwords, etc.) will be required and what is it expected to do? How can it be tested?
  • How reliable is the site’s Internet connections required to be? And how does that affect the backup system or redundant connection requirements and testing?
  • What process will be required to manage updates to the web site’s content?
  • What are the requirements for maintaining, tracking, and controlling page content, graphics, links, etc.?
  • Which HTML specification will be adhered to? How strictly? What variations will be allowed for targeted browsers?
  • Will there be any standard requirements for page appearance and/or graphics throughout a site or parts of a site??
  • How will internal and external links be validated and updated? And how often? will it happen?
  • Can testing be done on the production system, or will a separate test system be required?
  • How are browser caching, variations in browser option settings, dial-up connection variability, and real-world internet ‘traffic congestion’ problems to be accounted for testing?
  • How extensive or customized are the server logging and reporting requirements; are they considered as an integral part of the system and do they require testing?
  • How are CGI programs, applets, javascript, ActiveX components, etc. to be maintained, tracked, controlled, and tested?
  • Pages should be 3-5 screens max unless the content is highly focused on a single topic. If larger, provide internal links within the page.
  • The page layouts and design elements should be consistent throughout a site so that it’s clear to the user that they are still within a site.
  • Pages should be as browser-independent as possible, or pages should be provided or generated based on the browser-type.
  • All pages should have links external to the page; there should be no dead-end pages.
  • The page owner, revision date, and a link to a contact person or organization should be included on each page.

how we can test how many users can access the particular web site at a time . how we will create that much instances??

#2 Vijay

Pradeep, Manually creating all those simultaneous instances is practically not possible. Here Automation performance tools come into picture.
In automation tools you can specify how many user instances you want to create. These instances work as a virtual human user. Various load testing tool can be used to simulate this task e.g

Hi Vijay/Tiger2k,

I have one very obvious question since I am not finding good answer for this question.Please help in in getting correct answer for this question.
The best answer what i could think is as follows
“If i would join this organisation it would be altogether different LEARNING experience for me since this is a Product Compant and I am going to learn different process, different system that would definately nurture me careerwise”
I am neither pointing to salery nor blaming to current organisation.I am just what’s this company is having.
Please help me in getting this answer correctly…

#39 Shubha

hw to test the appln using loadrunner tool is infact very simpler job..b4 doing performance testing(PT) u should me much familiar with the tool…
u go with PT when appln s functionally stable. in PT u test the load ie, no of users expected by customer, will it support or not, behaviour of the appln wen too much load applied..u also study the transaction(txn) response time, txn rate, through put, hits per second, resource utilization…
In PT u dont write test cases, u just generate de script with respect to customers expectation lik no of loads u specify n sm more setting to be done

PT goes in dis way
1. Requirement & feasibility study
2. Identify the scenario
3. Test plan
4. Build the environment
4. Create Script
5. Design Performance scenario
6. Execute n monitor
7. Analyse the result
8. If requirement is met prepare test report ..u done with PT of ur appln
9 If requirement not met then perform tunning from 5th step ..repeate it untill u meet the requirement
10. If still not supporting then throw the appln on developer face n tell it should be rebuild ..plz do proper coding ;-)

#44 ashish

I recently gave an interview for website testing where they asked me these questions.

1) What would you do if you get a server error? The error is only on your system and all the other systems are working fine. Also all the backend services are up and running.

2) what would you do if the server error is on all the systems?

3) what would you do if you get the server error on clicking on a specific link?

Could someone please provide me answers for these questions?
