US 7757175 Method and system for testing websites
ABSTRACT – A method and system is provided for testing and analyzing websites via a test-enabled web browser. In the representative embodiment a user controls a test-enabled web browser via a set of pull-down menus, thereby choosing between alternative testing and analysis functional capabilities, selecting files in which to store recordings (scripts), choosing files into which to place test results and messages, and setting various parameters that affect how the testing and analysis functions are performed. When the user requests it, the representative embodiment provides for deep recording of user interactions as they relate to a specific web page currently on display in the browser view area, for extracting key information from the current web page sufficient to validate that a future playback does or does not produce the same effects on the chosen website page, for playing back a prior recording to confirm that a website page continues to pass the user-defined tests, and for providing detailed analyses based on the specific contents of the current website page. The general result of systematic use of the test-enabled browser on websites is improved content quality, demonstrated website server behavior for deep tests, quicker delivery by the website server, and better serviceability for e-business.
FIELD OF THE INVENTION
The present invention relates to software testing and, more particularly, to automated analysis and testing of websites.
BACKGROUND OF THE INVENTION
Websites are complex collections of information intended to be viewed and used and interacted with by sending information from a server (website server) over the Internet to users who work with this information from an internet browser client program (internet browser) that typically runs on a personal computer or other computing device. A common Internet browser is Internet Explorer (IE) by Microsoft Corporation. The IE browser runs on the Microsoft Windows NT and Windows 2000 operating systems.
Testing and analysis of websites is needed to: (i) confirm content and proper operation and proper content (i.e., functional testing and validation); (ii) determine delivered performance of a website server (i.e., website timing and tuning); (iii) analyze capacity of the website server by imposing realistic loads (i.e., website server loading); and (iv) identify erroneous website pages (i.e., site analysis).
Conventionally, there are several alternative methods that can be used to obtain information about how a website behaves when viewed from the Windows environment. One conventional method intercepts a Windows event loop. Another conventional method intercepts a HTTP protocol sequence by building a wrapper or proxy around an instance of the Internet browser. Both of these conventional methods have disadvantages. One disadvantage of intercepting the Windows event loop is that every keyboard activity and/or mouse activity at the primitive level of its interaction with the operating system must be handled. This leads to cumbersome programming. One disadvantage of intercepting of the HTTP protocol sequence via a wrapper or proxy is that the focus is on the communication between the Internet browser and the server.
Thus there is a need for improved approaches to testing websites.
SUMMARY OF THE INVENTION
Broadly speaking, the invention relates to improved approaches for testing websites. According to one aspect of the invention website testing is performed in a browser environment. As such, information for testing can be obtained from a browser that is able to perform automated analysis and testing of websites. For example, the browser can emulate operation of an Internet Explorer (IE) browser while having additional functionality to provide automated analysis and testing of websites. The invention can thus be implemented in a test-enabled Internet browser.
The invention can be implemented in numerous ways including, a method, system, device, graphical user interface, and a computer readable medium. Several embodiments of the invention are discussed below.
Other aspects and advantages of the invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the invention.
