The C++ prototype extends the ContainerServices class. The important methods to consider here, are the activateComponent/deactivateComponent which are to be used by the setUp and cleanUp methods in Unit testing.
| Code Block |

class MockContainerServices : public maci::ContainerServices {
public:
MockContainerServices(ACE_CString& componentName, PortableServer::POA_ptr poa);
~MockContainerServices();
virtual CORBA::Object* getCORBAComponent(const char* name);
//...
template<class TAdvancedObject> void activateComponent(const char* name) {
TAdvancedObject* obj = new TAdvancedObject(name, this);
obj->initialize();
obj->execute();
this->comps[name] = obj
};
virtual deactivateComponent(const char* name) {
acscomponent::ACSComponentImpl* obj = dynamic_cast<acscomponent::ACSComponentImpl*>(this->comps[name]);
try {
obj->cleanUp();
} catch (...) {
obj->aboutToAbort();
}
this->comps.erase(name);
}
protected:
std::map<std::string, CORBA::Object_var> comps;
}; |
The getCORBAComponent method was also extended in order to return the component from 'comps' the std::map:
| Code Block |
|---|
| language | cpp |
|---|
| title | MockContainerServices.cpp |
|---|
|
CORBA::Object* MockContainerServices::getCORBAComponent(const char* name){
if (comps.find(name) == comps.end()) {
maciErrType::CannotGetComponentExImpl ex(__FILE__, __LINE__, "MockContainerServices::getComponent");
ex.setCURL(name);
throw ex;
}
return CORBA::Object::_duplicate(comps[name].in());
} |
Later on, in the test implementation we would do something similar to:
| Code Block |
|---|
| language | cpp |
|---|
| title | TestExample.cpp |
|---|
|
MockContainerServices* mcs = nullptr;
setUp() {
mcs = new MockContainerServices(cn, nullptr);
mcs->activateComponent<MaciTestComponentImpl>("TEST_COMP1");
mcs->activateComponent<MaciTestComponentImpl>("TEST_COMP2");
}
cleanUp() {
mcs.deactivateComponent("TEST_COMP1");
mcs.deactivateComponent("TEST_COMP2");
delete mcs;
mcs = nullptr;
}
//The tests should not know anything about the changes we've done, but they rely on this mcs instance just for convenience
test_example() {
MACI_TEST::MaciTestComponent_var comp = mcs->getComponent<MACI_TEST::MaciTestComponent>("TEST_COMP1");
comp->some_method(...); //If some_method retrieves a component, it should also work normally, since on creation, we passed an instance of MockContainerServices
