Description
PFSK129 terminal board 3BSE007284R1 unit testing refers to the smallest testable unit
in the software to check and verify the meaning of the unit in the unit test, generally speaking,
according to the actual situation to determine its specific meaning, such as C language unit
refers to a function, Java unit refers to a class, graphical software can refer to a window or a menu, etc. Unit testing is the lowest level of testing activity to be carried out in the software development process. The independent unit of software
will be tested in isolation from the rest of the program.
PFSK129 Terminal Board 3BSE007284R1 In a traditional structured programming language, such as C,
the unit to be tested is usually a function or subprocedure. In an object-oriented language like C++, the basic unit
to be tested is the class. For Ada, developers can choose whether to unit test in separate procedures and functions or
at the Ada package level. The principles of unit testing are also extended to fourth generation language (4GL) development.
Here the basic unit is typically divided into a menu or display interface. Other development activities that are often associated with
unit testing include Code reading revlew, Static analysis Static analvsis, and dynamic analysis Dnamic analvsis. Static analysis is
the study of the source code of the software, looking for errors or collecting some metrics, and does not require the compilation
and execution of the code. Dynamic analysis provides information about execution, row tracking, time analysis, and test coverage by observing the actions of the software while it is running.
