I’m using gtest for testing my code base, I need to override mock function to throw exception as follow:

ACTION(MyThrowException)
{
    throw std::runtime_error ("run time error") ;
}

TEST_F(MyTest, MyUT)
{
     ON_CALL(*mockObj, mockMethod()).WillByDefault(MyThrowException());
    
     myAppPtr->Start();
}

in Start function in my solution, I’m trying to catch the exception as follow:

try 
    {
        
         obj.mockMethod();
    }
    catch(const std::runtime_error& e){
        std::cout<<e.what()<<std::endl;
    }
    catch (...)
    {
         std::cout<<e.what()<<std::endl;
    }

but every time the exception didn’t caught and I got : terminate called after throwing an instance of ‘std::runtime_error

how can I trace such issue?
