Exception in ctor not propagated

[Brunni]

Hi,

I really like having DI in my code it makes it very readable and testable!

My Problem:
If my configuration settings are wrong, the constructor throws an exception stating which value is missing. This exception is swalloed and the program terminates with errorcode 3.

Example ctor

cerr << "Starting ctor" << endl;
config->getEntry("threshold"); // this throws exception
cerr << "ctor finished" << endl;

Result on console: I see the first message and then program terminates.

System:

• Execution with GTest framework.
• Windows, Visual Studio 2015.3

I think this happens due to the fact that injector's create method marked as noexcept. When instantiating a dependency throws, the exception isn't caught inside the create, thus terminating the application, because the noexcept 'contract' is breached.

I'm wondering though, about the rationale of making it noexcept?
