Why does a test pass if run as "rake cucumber:wip" and fail as "rake cucumber:all"

I have a feature file and step definitions. I put @wip at the top of the feature file. Then I run

rake cucumber:wip

and I get 8 passed tests, no fails. Then all I do is remove the @wip from the feature file and run

rake cucumber:all

and one of my step definitions fails with a nil pointer. I can only th开发者_如何学JAVAink of two things: 1. there is a difference between the wip and default profiles, but when I look in cucumber.rake file they appear to be the same 2. there is something about running my feature tests with the other feature tests or database transactions that is wiping something out. Has anybody seen something like this before?

Rails 2.2.2 cucumber 0.7.2 cucumber-rails 0.3.1

rake cucumber:wip runs cucumber with the --wip switch.

This makes cucumber "revert" the results of scenarios: if an error occurs during execution it "succeeds"; if all steps run smoothly, it reports a failure.

The idea is that if all steps run without errors, it is not a "work in progress" and shouldn't be considered (tagged) as such anymore.
