Mock Kernel#require and #load about fakefs

[jmhodges]

I can't think of a use case for this. Do you have one?

It may be useful, but maybe not for this library. It'd be a nice to have a mechanism for faking dependencies for libraries that manage dependencies.

I imagine something like this: http://gist.github.com/297952
The #require mock is only activated if required (= needed).

The usecase i encountered yesterday is a class loading modules by configuration. I could still use Object.eval, but then I would align my codebase to my testing code. http://github.com/lgierth/pakada/blob/master/lib/pakada.rb#L43

I'll see if I can send a patch/pull request during the next days.

Best regards,

Voila: http://github.com/lgierth/fakefs/tree/topic/fake-require

You have to explicitly say that you want to fake Kernel#require, either by loading it before FakeFS.activate! or by loading it and calling FakeFS::Require.activate!.

Any thoughts on this?

I think I am now nearly completely faking #require, including the possibility to require files outside of FakeFS that reside in gems and to apply the faked #require also to #autoload.

Anyway the tests aren't complete and there's no documentation, I'll see if I can manage this during the next days.

Best regards,
Lars

I released this as fakefs-require some weeks ago.
