Rake test failing in test environment only

I am running "rake test" over my Rails 3.0.7 (Ruby 1.8.7) project via the command line.

My rails app is a fairly basic out-the-box app, as I am still learning. E.g. my Gemfile is:

source 'http开发者_运维问答://rubygems.org'
gem 'rails', '3.0.7'
gem 'sqlite3'

When I do this without specifying the environment, it works. I presume this is hitting development, as when I try and point at the development environment, it still works ! Also when I run "rake test:units" or "rake test:functionals" these work without error too.

However, when I run against the test environment, the unit tests fail to run ? I have tried this both from Rubymine IDE and command line with the same results.

The trace outputs look as follows - firstly plain "rake test" :

C:\Users\Ben\dev\railstest>rake test --trace

And now the failing run against the test environment

Errors running test:units!

There is no more text in the error message, and no further indication what the errors actually are. I have re-run db:schema:load on both sqlite3 environments and db:seed to populate a few database tables too, although the test data is loaded via fixtures normally.

I figure the problem here is trying to run unit tests against the test environment, but I can't understand why ?

When you run rake test all unit, functional, and integration tests are run in the test environment. From what you've shown, the tests are working exactly as expected. You don't need to explicitly tell rake to use the test environment - that is assumed.
