Every software tester performs application Testing daily in his career. And today here we’ll get a brief understanding of application testing.

There are two kinds of applications: desktop and web. For desktop applications, testing should consider the UI, business logic, databade, reports, roles and rights, integrity, usability and data flow. Then while for web applications, testers should pay more attention to performance, load and security of the application. Therefore, AUT is either desktop software or a website.

Today only three universal application testing methodologies are accepted: Black Box, White Box, and Grey Box. However, application testing tools are various. Here we list some most improtant and fundamental features of the functional testing tools:

1. Record and Play

2. Parametrize the Values

3. Script Editor

4. Run (the test or script, with debug and update modes)

5. Reprot of Run session

Application Testing cycles includes Somke Testing, Sanity Testing, Functional Testing, and Regression Testing. Application Testing is a vast subject and the primary activity of any software tester.
