Add option to emit a warning when non-existant classes/interfaces/methods are stubbed/mocked #12

I'd like to do something about this for 3.8.

One option would be to have a new method that only mocks existing things and one to create new stuff and do proper error reporting there "deprecating" getMock.

My suggestion for the new one would be mock.

So you'd say


another option would be to slap another parameter on getMock and make a MockBuilderFunction allowCreationOfNonExistingClasss or something.

Maybe even have a release that only has a warning telling you

"You are mocking a non existing class. This might be not what you wanted. If this is in intentional behavior please use the $allowNonExisting flag."

Having a new function would allow for more cleanup but require a lot more work/docs/etc


What does the documentation say for stubbing/mocking things that don't already exist? Does it say "don't do this"? Because if that's so, we should be able to make 3.8 throw exceptions when this happens. If this breaks BC for people 1) they did something wrong in the first place and we just never told them until 3.8 2) they're tests anyway.


@bartfeenstra I don't think the documentation says anything about stubbing/mocking classes/interfaces/methods that don't exist.

This PR was merged into the 2.0.x-dev branch.


remove not needed logger tests

The `isset` checks on `$app['logger']` make no sense since `Application` always sets the logger (to `null`). Checks for `!empty` would be more safe/complete (altough `!empty && instance_of('LoggerInterface')` would be more ideal in some cases).
Updating the unit tests is more complicated because some code under test depends on classes outside of Silex.
Hacking the `class_exists` function or use `mocking` of classes that do not exists (@see sebastianbergmann/phpunit-mock-objects#12) would effect the whole test suit (as @stof pointed out).
