From time to time, the browser and Web pages function in conjunction with the application’s server to activate other applications (see Figure below). Such servers are parameterized software applications supplied by software vendors; consequently, after the acceptance tests they fall into the category of “trusted” code. Such a server includes a database which stores both the contents of the pages the data received by users of the system.
Such systems automate certain aspects of the user service. The page can receive input to a user order form, create a customer record, activate an application that automatically generates an account number and password, and then forward this account information to the user.
Such systems are characterized by a high degree of modularity. Application programs can undergo changes, but no modifications are made to the Web server, while Web pages are subject to minor modifications only. Changes to Web pages involve insignificant changes to the data that are naturally stored in XML format.
Security testing companies use effective tools to scan ecommerce resources for security vulnerabilities. By so doing they manage to address issues before the system is made available to the wider public.
There are two facets to testing of such systems. First, do test scenarios successfully handle the tasks assigned to them? In a very short time, many versions of browsers and their own scripting languages have appeared. As a result, until you deploy the browser into a managed environment in which everyone works with the same version, the test must be performed on different combinations of the browser and the scripting language versions.
Frames and tables can serve as examples of tools that have altered drastically with transition from one environment to another and have caused very different display results. Many developers provide alternative paths depending on whether the browser supports frames or not. It is necessary to schedule the execution of test cases that can provide coverage for all these probabilities.
Secondly, are the current data correct and are they presented in the form required by applications and Web pages? Testing this part requires scenarios in which the Web site data are displayed in conjunction with the types of data that the user would enter. The data types for each input are analyzed, equivalent classes are determined, and samples are taken from each class.
