rspec-english

Better English for RSpec descriptions

Description

rspec-english aims to modify how RSpec builds descriptions of specs/tests in order to make them read like more natural English.

Specifically, context example groupings are modified to be placed after the test description in the full description output, such that the following code would read "RSpec outputs real English when rspec-english is available":

describe RSpec do
    context 'WHen rspec-english is available' do
        it 'outputs real English' do
            RSpec.english.should be_true
        end
    end
end

Motivation

RSpec context groups are usually adverbial clauses, e.g. "with ..." or "when ...". Following RSpec's standard description generation, these are placed directly after the subject of the sentence (i.e. the description of the preceeding describe groups). However, in standard English, these clauses are nearly always placed either at the beginning of the sentence, if emphasis is desired, or, more commonly, at the end of the sentence.

Known Defects

1. Currently describe blocks nested within a context are still placed before the test description. I have not yet decided if this is desirable or not.
2. It is possible for some nested contexts to come out still reading as less-than-standard English. They are normally ordered as manner, place, and then time, but the string will be generated in order of nesting, not in their natural English order.

Compatibility

I've only tested this with rspec-core 2.13.1, but I see no reason why it wouldn't work with earlier versions as well. I've set a runtime dependency for ~> 2.13.1, but I'd be glad to update it if you let me know an earlier version works.

Future

I would like to rewrite this so that it takes into account a rudimentary model of a normal English sentence, in order to fix defect 2, above. Other suggestions are, of course, welcome. One benefit of doing it this way is that it will obsolete the modification to RSpec::Core.context and will slim down some of the other modifications a bit.

In addition, I would like to eventually modify descriptions and join them with conjunctions where possible, e.g. turning "when one thing when another thing" into something more readable like "when one thing and another thing." Ideally, this can be done without requiring any modification to tests.
