Data binding is one of the more useful features of a web test. It allows you to have a different set of data used for each iteration of a web test. For example, suppose you have a list of users you would like to simulate using your web application. You could add a data source which contains the list of users and passwords. Then you would bind this data source to the user name and password fields on your login request. Now each iteration of the web test will simulate a different user. The following are instructions for adding some of the most common types of data sources to a web test.
Adding a CSV(txt) Data Source
Adding an Access Database as a Data Source
