A variation on this type of tool is for testing of web sites. Here, the "interface" is the web page. However, such a framework utilizes entirely different techniques because it is rendering HTML and listening to DOM Events instead of operating system events. Headless browsers or solutions based on Selenium Web Driver are normally used for this purpose.
Selenium is perhaps the most popular automation framework that consists of many tools and plugins for Web application testing. Selenium is known for its powerful capability to support performance testing of Web applications. Selenium is a popular choice in the open-source test automation space, partly due to its large and active development and user community.
This article uses the term “tester” to refer to the person involved in testing software with automation tools. It is not meant to distinguish by job title or technical proficiency. Jim Hazen describes himself as a hybrid, or “technical tester,” because he can write test scripts and develop what he refers to as “testware.” The trend is to hire for multiple skillsets, but that does not mean the non-technical stakeholders involved in software development don’t benefit from automation testing.
