3. Web Browser

A. Browser Compatibility

B. How To Check The Compatibility

C. Tool Browershots

Browser compatibility is the ability of the Web browser to properly interpret the hypertext markup language (HTML) that renders Web pages

Site displays correctly? On different browsers have the same layout,

same design? Time to load ? Site layout is reasonable, content updates

clearly?

What we need to test ?

Screen size Information provided at this site, including

note boards, clear error messages? Font-style, font size ? Popup, Ads? Be uncomfortable for the

viewer?

What we need to test ?

The site must be displayed in common browsers like IE, Firefox, Chrome, Opera, Safari ...

Each of brower is different structure, design Your browser may not support the technologies

that your website is using. The site can display well in browser but not good

in other browsers Site has good displays on the

new browser version?

Different windows version has different architecture (XP & Windows 7) The upgrade window Check on mac, linux

Compatible with the OS

Check the web page displayed on the screen of mobile devices

Mobile browsing

Develop web site with appropriate length so that users can print Standard printer Provides links to printable materials if the site has the resources users will want to print

Printing options

Step 1: Download and install some common browsers like Internet Explorer, Mozilla Firefox, Opera and Safari. Step 2: Check on http://browsershots.org/ to capture images on your site operating systems and different browsers. Step 3: Try checking the google error page with the keywords "internet explorer firefox difference", or "web page can not be displayed in Firefox" etc ...

Compatibility between browsers

Compatibility between browsersTry on the online validator test as http://wave.webaim.org/ and http://www.totalvalidator.com/ to analyze the content

• Performance test (PT) is an automated testing method in order to determine the speed, load and ability to trust level of the software in the environment many users

• Include Load test và Stress test

Performance test

• Load testing is the process of subjecting a computer, peripheral, server, network or application to a work level approaching the limits of its specifications.

• Load testing can be done under controlled lab conditions to compare the capabilities of different systems or to accurately measure the capabilities of a single system.

• Load testing is a part of a more general process known as performance testing

Performance testLoad Test:

• Load testing can obtain a qualitative idea of how well a system functions in the "real world."

• Pinpoint bottlenecks, bugs and component limitations -> find solution to solve it.

Performance testLoad Test:

Stress Test:

• Stress testing is a form of testing that is used to determine the stability of a given system or entity. It involves testing beyond normal operational capacity, often to a breaking point, in order to observe the results. Stress testing may have a more specific meaning in certain industries, such as fatigue testing for materials

LOADRUNNER FEATURES ?

Load Generator

Multiple machines can be set up to act as load generators in concert

Analysis

The Analysis tool takes the result from the completed scenario and prepares graphs and reports that are used to correlate system information and identify bottlenecks and performance issues

5. Web service testing

A Web service is a method of communication between two electronic devices over the web (internet).

The W3C defines a "Web service" as "a software system designed to support interoperable machine-to-machine interaction over a network". It has an interface described in a machine-processable format (specifically Web Services Description Language, known by the acronym WSDL).

What is web service?

How does it work ?

Basic Web Service platform is SML + HTTPWeb services platform elements:

SOAP (Simple Object Access Protocol)UDDI (Universal Description, Discovery and Integration)WSDL (Web Services Description Language)

How does it work ?

SOAP is an XML-based protocol to let applications exchange information over HTTP.SOAP is a protocol for accessing a Web Service.

SOAP is based on XMLSOAP stands for Simple Object Access ProtocolSOAP is a communication protocolSOAP is a format for sending messages

What is SOAP?

SOAP is designed to communicate via Internet SOAP is platform independentSOAP is language independentSOAP is simple and extensibleSOAP is a W3C standard

What is SOAP?

WSDL is an XML-based language for locating and describing Web services.

WSDL stands for Web Services Description LanguageWSDL is based on XMLWSDL is used to describe Web servicesWSDL is used to locate Web servicesWSDL is a W3C standard

What is WSDL?

UDDI is a directory service where companies can register and search for Web services.

UDDI stands for Universal Description, Discovery and IntegrationUDDI is a directory for storing information about web servicesUDDI is a directory of web service interfaces described by WSDLUDDI communicates via SOAPUDDI is built into the Microsoft .NET platform

What is UDDI?
