how to use Parasoft Dynamic stubs #1

wsubers

Hello Community,

I am a first time user of Parasoft's dynamic stubs. I am evaluating this feature as an alternate to using Google mock.

If I have a function:

void Func1()
{
int a = 1;
Func2(a);
a++;
Func2(a);
}

In my test case for testing Func1, what is the appropriate Dynamic Stubs calls to validate the first time Func2 was called, the input parameter a was equal to 1 and the second time Func2 was called, the input parameter a was equal to 2?

Hello,

The simplest solution is to add the following two lines to the test case:

CPPTEST_ON_CALL("Func2")->If()->LP()->RunId()->Equal()->Value(1)->RP()->If()->LP()->Arg("a")->NotEqual()->Value(1)->RP()->Fail("Argument \"a\" not equal 1");

CPPTEST_ON_CALL("Func2")->If()->LP()->RunId()->Equal()->Value(2)->RP()->If()->LP()->Arg("a")->NotEqual()->Value(2)->RP()->Fail("Argument \"a\" not equal 2");

I will discuss only the first one since the second one is exactly the same, there are 3 parts:

1.
CPPTEST_ON_CALL("Func2")->
Register operation for the "Func2" stub id

2. If()->LP()->RunId()->Equal()->Value(1)->RP()->
   Check the stub call number. Counting starts from 1.
   Remaining part will be executed only if this evaluates to true.

3.
If()->LP()->Arg("a")->NotEqual()->Value(1)->RP()->
Check the value of parameter (this action is executed only if "RunId" condition evaluated to true)

4.
Fail("Argument \"a\"~~~~ not equal 1");
Report failure (executed only if parameter check evaluated to true)

Hope this helps
