How to use Parasoft Dynamic stubs #4

wsubers

On https://docs.parasoft.com/display/CPPDESKE1033/Working+with+Complex+Types, can you provide an example of the stub for Line moveLine(Line line, int xoff, int yoff); but using the “Basic Approach to Working with Complex Types”?

Default stub for Line moveLine(Line line, int xoff, int yoff) will look similar to this:

::Line CppTest_Auto_Stub_moveLine (::Line line, int xoff, int yoff) 
{
    ::Line __return = ::Line();
    int __callOrig = 0;

    CPPTEST_ACTUAL_CALL("moveLine")
        ->WithPtrArg("line", &line, tgr_void_type())
        ->WithRefArg("xoff", &xoff, tgr_int_type())
        ->WithRefArg("yoff", &yoff, tgr_int_type())
        ->WithPtrArg("__return", &__return, tgr_void_type())
        ->WithRefArg("__callOrig", &__callOrig, tgr_int_type())
        ->End();
    if (__callOrig) {
        ...
        ...
    }
    return __return;
}

In order to make the following complex type members available to test cases:

IN: line._p1._x, line._p1._y, line._p2._x, line._p2._y
OUT: return._p1._x, return._p1._y, return._p2._x, return._p2._y

the CPPTEST_ACTUAL_CALL could be extended like this:

::Line CppTest_Auto_Stub_moveLine (::Line line, int xoff, int yoff) 
{
    ::Line __return = ::Line();
    int __callOrig = 0;

CPPTEST_ACTUAL_CALL("moveLine")
   ->WithRefArg("line_p1_x", &line._p1._x, tgr_int_type()) // expose line._p1._x
   ->WithRefArg("line_p1_y", &line._p1._y, tgr_int_type()) // expose line._p1._y
   ->WithRefArg("line_p2_x", &line._p2._x, tgr_int_type()) // expose line._p2._x
    ->WithRefArg("line_p2_y", &line._p2._y, tgr_int_type()) // expose line._p2._y
    ->WithRefArg("xoff", &xoff, tgr_int_type())
    ->WithRefArg("yoff", &yoff, tgr_int_type())
    ->WithRefArg("return_p1_x", &__return._p1._x, tgr_int_type()) // expose return._p1._x
    ->WithRefArg("return_p1_y", &__return._p1._y, tgr_int_type()) // expose return._p1._y
    ->WithRefArg("return_p2_x", &__return._p2._x, tgr_int_type()) // expose return._p2._x
    ->WithRefArg("return_p2_y", &__return._p2._y, tgr_int_type()) // expose return._p2._y
    ->WithRefArg("__callOrig", &__callOrig, tgr_int_type())
    ->End();
    if (__callOrig) {
        ...
        ...
    }
    return __return;
}

As a result, test cases could access those additional complex type members exposed from stub:

CPPTEST_ON_CALL("moveLine")->Arg("return_p1_x")->Assign()->Value(0);
CPPTEST_ON_CALL("moveLine")->Arg("line_p2_y")->Assign()->Value(12);
