Procedures

System Testing for C

You can also use procedures to build more compact test scripts. The following are characteristics of procedures:

They must be defined before they are used in scenarios.
They do not return any parameters.

A procedure begins with the keyword PROC and ends in the sequence END PROC. For example:

HEADER "Socket Validation", "1.0", "beta"

PROC function ()

...

END PROC

SCENARIO first

...

CALL function ()

...

END SCENARIO

SCENARIO second

SCENARIO level2

FAMILY nominal, structural

...

END SCENARIO

A procedure can call sub-procedures as long as these sub-procedures are located above the current procedure.

Procedure blocks can take parameters. When defining a procedure, you must also specify the input/output parameters.

Each parameter is described as a type followed by the name of the variable.

The declaration syntax requires, for each argument, a type identifier and a variable identifier. If you want to use complex data types, you must use either a macro or a C or C++ type declaration.

Example

In the following example, the argument to procedure function1 is a character string of 35 bytes. The arguments to procedure function2 are an integer and a pointer to a character.

HEADER "Socket Validation", "1.0", "beta"

#typedef char string[35];

##define ptr_car char *

PROC function1 (string a)

...

END PROC

PROC function2 (int a, ptr_car b)

...

END PROC

SCENARIO first

...

CALL function1 ( "foo" )

...

END SCENARIO
