Q. 1: Consider a Web Server Supporting 10,000 concurrent users who request documents from a pool of 10 different HTML documents (with an average size of 2K each) every 3.5 minutes. Calcualte the bandwidth requirement for handling this throughput?

Throughput = [10,000x(2x1024x8)} / (3.5 x 60) = 780,190 bps
or
= [10000 x (2 KB x 1024 bytes/KB x 8 bits/byte)] / (3.5 minx sec/min)

Therefore The Bandwidth (B.W) = 780,190 bps

Q. 2: Explain any of the load / performance testing tool for web application?

Tool type: Web-load simulator used for the performance analysis.

Input: Stimulated user requests.

Output: Various performance and analytical reports.

Primary user: Tester.

Secondary user: Developer.

Technology Principle: This tool enables us to simulate thousands of users accessing the website, in addition to other E-commerce and E-business activities. Virtual load can also simulate various versions of web browsers and network bandwidth. The simulated load is applied to the server whereas the performance data is collected and plotted in several useful report formats for further analysis.

Q. 3: What are the points of differences among Inspection & Walkthrough in context of Web Application?

	Inspection	Walkthrough
1	It is a five-step process that is well-formalized.	It has fewer steps than inspection and is a less formal process.
2	It uses checklists for locating errors.	It does not use a checklist.
3	It is used to analyze the quality of the process.	It is used to improve the quality of product.
4	This process takes longer time.	It does not take longer time.
5	It focuses on training of junior staff.	It focuses on finding defects.

Q. 4: How test cases may be developed for website testing?

Generated loads may be designed to interact with servers via a web browser user interface (WBUI).

Consideration must be given to the types of requests that are sent to the server under test by the load generator and the resources available to the load generator.

Q. 5: A web-based project has various attributes to be used as metric. List some of them.

Some measurable attributes of a web-based projects are

(a) Number of static web pages used in a web-project. By 'static', we mean no databases.

(b) Number of dynamic web pages used in a web-project. By 'Dynamic', we mean, 'databases' are also connected to the web-pages.

(c) Word count metric which counts the total number of words on a page.
