Define static testing and dynamic testing.

Static testing is another name for in-process reviewing. It means that the test is being performed without executing the code. Static testing occurs throughout the development life cycle; however, a large part of it takes place during the requirements and design phases in the form of walkthrough inspections, and system reviews. Other examples of static testing include code analyzers or writing analyzers.

Dynamic testing (also known as program testing) implies that the code is being executed on a machine.
