Function Capturing

For a user function to be exposed to the STRIDE Test System it needs to be captured. Once made available it could be remoted or doubled.

Specification

By using the STRIDE special scl_function pragma any global function could be captured. For example to capture:

/* foo.h */
int foo(void);

create a new header file and add the following pragma statement:

/* foo_SCL.h */
#include "foo.h"

#ifdef _SCL
#pragma scl_function(foo)
#endif

By simply passing the new header file to the STRIDE Build Tools the captured function would become part of the Intercept Module.

Remoting

The simplest form of capturing (using scl_function with no additional arguments) would make a function exposed for external to the target use (remote calling). Such exposure provides a number of uses, among them is fuxturing a test script.

Interception

A function could be captured for the purpose of interception. When intercepted it could be dynamically substituted to implement on-the-fly mocks, stubs, and doubles. The Test Double article provides more details on the topic.
