Q: Why was MagicMock produced a independent thing instead of just folding the ability in the default mock item?

The typical illustration can be the library-delivered ::operator new and ::operator delete implementations. We frequently get in touch with them "overloadable" in everyday language, even though formally They can be replaceable

On the other hand, SO must have the capacity to stand by yourself even when the remainder of the Web disappears! By all implies hyperlink to a different supply, but I prefer to place some meat in the answer as well.

Right here "2" is often a "magic" range, which happens to be factored out to some symbolic continual default_padding inside the context on the GUI UX of "my system" to be able to help it become use as default_padding speedily understood while in the higher context from the enclosing code.

The example higher than is very good simply because "two" by alone could possibly be something. Only after we limit the range and area of knowing to "my program" wherever 2 is definitely the default_padding during the GUI UX portions of "my plan", can we last but not least make sense of "two" in its appropriate context.

Other programs can go through the 1st few figures of the file and magic properly recognize GIFs. The Threat is that random binary info can consist of these exact same figures.

The result is ALL basic values are changed with symbolic constants. As I concur along with your conclusion I obtain this a lot less than excellent.

Like gbjbaanb the right way reported, the STL could be applied in plain C++, with no counting on any sort of compiler "magic".

Within the uncommon instances where I find the necessity to use these kinds of Magic Figures, I set them as being a const in my code, and document why They are really used, how they do the job, and where by they came from.

Which means it is actually unachievable to help make an implementation of the thing and String classes in pure(*) Java. Now This really is what I mean with "magic": to make an implementation of such courses, you will want some Particular aid with the compiler.

std::initializer_list requirements compiler help and cannot be reimplemented as One more course (so far as I am aware), while I am undecided if it counts as it's in c++0x.

Evaluating from ANY is usually practical, for example, comparing almost every important in between two dictionaries exactly where some worth is calculated utilizing a mock.

The beneath primary reply has become outdated. Be sure to just Stick to the Guidance denoted beneath the "dependencies" portion.
