Test Documentation in C/C++

Stride provides an integrated solution for automatically extracting documentation for your test units using the well-known doxygen format.

Test documentation

#include <srtest.h>
/*! This Suite does lots .. */  
class MyTest {
public: 
    /*! Check on Foo .. */
    void CheckFoo();
    /*! Check on Boo .. */
    void CheckBoo();
};
#pragma scl_test_class(MyTest)


In order to enable test unit documentation, here is summary of the necessary steps:

  • document your test unit source with doxygen formatted blocks. Since only header files are typically passed to the Stride Compiler, we recommend you place your documentation in the header file.
  • configure your build/make process to call the Stride Compiler with the additional --documentation flag. If you are using one of our preconfigured makefiles in a sandbox environment, this option has already been enabled.
  • run your build process to produce a Stride database and Stride enabled target application.
  • start your application and execute the Stride Runner to connect and run the tests.
  • The generated report will contain description information for the test suites and test cases generated from the doxygen blocks.

Doxygen has a rich set of tags and formatting options aimed at comprehensive source documentation. The Stride test framework uses doxygen on a per-file basis to extract standalone documentation for individual test units and their methods. As such, we only support limited set of doxygen features in the code documentation. The Stride test framework supports the following doc formatting:

  • custom HTML formatting
  • lists (ordered, unordered, definition)
  • code blocks
  • bold and emphasis text

More advanced doxygen formatting tags (such as tables and parameter lists) are not supported at this time, but will likely be in future releases.

Test Classes

Source documentation is generally straight-foward, with doc blocks preceding the corresponding class and method declaration.


#pragma once
#include <srtest.h>
 
 /*! Brief description for MyTestUnit (optional)
    More detailed documentation goes here.
    <a href="http:\\myinfo.mysite.com\MyTestUnit.html">More Info</a>
 */
 
 
class MyTestClass
{
  public:
    /*! 
       Description for Test_1 here.  
    */
    bool Test_1();
 
    /*! 
       Description for Test_2 here.  
    */
    bool Test_2();
};
 
#ifdef _SCL
#pragma scl_test_class(MyTestClass)
#endif


Test C-Classes

Source documentation must relate to the structure that is used as the "C-Class" for the test unit. Since a C-Class uses function pointers to call its individual tests, test method documentation must be associated with the corresponding structure function pointer member. As such, method documentation for C-Classes must be in the header file.


#pragma once
#include <srtest.h>
 
/*! Brief description for my_c_class(optional)
   More detailed documentation goes here.
*/
typedef   struct my_c_class
{
    /*! 
       Description for Test_1 here.  
    */
    int (*Test_1)(struct my_c_class* pcc);
 
    /*! 
       Description for Test_2 here.  
    */  
    int (*Test_2)(struct my_c_class* pcc);
} my_c_class;
 
#ifdef __cplusplus
extern "C" {
#endif
void  my_c_class_init(struct my_c_class* pcc);
#ifdef __cplusplus
}
#endif
 
#ifdef _SCL
#pragma scl_test_cclass(my_c_class, my_c_class_init)
#endif


Test FLists

Since F-Lists have no specific storage entity (class or struct) to which they are associated. As such, the only way to provide unit-level documentation for FLists is to document the source file in which its methods are declared. The unit documentation is associated with its file using the \flist tag. Because of this restriction, we recommend that you generally confine each Test FList to it's own source file pair (.h and .c). The test methods associated with an FList are documented as expected, with the documentation block preceding the function declaration.


(source file name is my_flist.h in the example below)

#pragma once
#include <srtest.h>
 
#ifdef __cplusplus
extern "C" {
#endif
 
/*! 
\flist my_flist.h
\brief Summary description for my_flist(optional)
More detailed documentation goes here.
*/
 
/*! 
   Description for Test_1 here.  
*/
int Test_1();
 
/*! 
   Description for Test_2 here.  
*/
int Test_2();
 
#ifdef __cplusplus
}
#endif
 
#ifdef _SCL
#pragma scl_test_flist("my_flist", Test_1, Test_2)
#endif
