What is Web Test?
A Web test, also called a declarative Web test, consists of a series of HTTP requests. Web tests work at the protocol layer by issuing HTTP requests. Web tests do not run JavaScript. However, you can simulate JavaScript actions at runtime by using Web test plug-ins, Web test request plug-ins, extraction rules, or coded Web tests.
Web tests are used to test the functionality of Web applications and to test Web applications under load. Web tests are used both in performance tests and stress tests.
