A checkpoint verifies that expected information is displayed in an Application while the test is running. You can add eight types of checkpoints to your test for standard web objects using QTP. A page checkpoint checks the characteristics of an Application. A text checkpoint checks that a text string is displayed in the appropriate place on an Application. An object checkpoint (Standard) checks the values of an object on an Application. An image checkpoint checks the values of an image on an Application. A table checkpoint checks information within a table on a Application. An Accessibilityy checkpoint checks the web page for Section 508 compliance. An XML checkpoint checks the contents of individual XML data files or XML documents that are part of your Web application. A database checkpoint checks the contents of databases accessed by your web site.
