`rake test(:functionals|:units|....)` loads the environment twice

#4759

Here's the current flow.

** Invoke test:units (first_time)
** Invoke test:prepare (first_time)
** Invoke db:test:prepare (first_time)
** Invoke db:abort_if_pending_migrations (first_time)
** Invoke environment (first_time)
** Execute environment
==> [config/environments/development.rb loads here] <==
** ultrasphinx: configuration file not found for "development" environment
** ultrasphinx: please run 'rake ultrasphinx:configure'
** ultrasphinx: spelling support not available (raspell configuration raised "uninitialized constant Ultrasphinx::Spell::Aspell")
** Execute db:abort_if_pending_migrations
** Execute db:test:prepare
** Invoke db:test:load (first_time)
** Invoke db:test:purge (first_time)
** Invoke environment 
** Execute db:test:purge
** Execute db:test:load
** Invoke db:schema:load (first_time)
** Invoke environment 
** Execute db:schema:load
** Execute test:prepare
** Execute test:units
==> [config/environment.rb loads here] <==

The data for the bracketed annotations were found by adding puts statements to those files.

This becomes more of a problem the longer the environment takes to load. For example, the rails3 branch of gitorious.org takes 20-25 seconds to load because of the high number of routes (which I will probably file a separate issue for - that's a long time!). Here (and attached) is the output of rake routes. Having to wait about a minute for the tests to start running makes TDD rather tedious.

I'm facing the same issue with running my tests, due to the double loading of the environment.What is the reason that the environment is loaded twice?

I tested with rails 3.0.4, created an empty application and scaffold of users.
With a "puts" in config/environment.rb, i did:

rake test -t (in /home/roger/dev/trivial/temp/raketest) Invoke test (first_time) Execute test Invoke test:units (first_time) Invoke test:prepare (first_time) Invoke db:test:prepare (first_time) Invoke db:abort_if_pending_migrations (first_time) Invoke environment (first_time) Execute environment ENV LOADED ! Execute db:abort_if_pending_migrations Execute db:test:prepare Invoke db:test:load (first_time) Invoke db:test:purge (first_time) Invoke environment Execute db:test:purge Execute db:test:load Invoke db:schema:load (first_time) Invoke environment Execute db:schema:load Execute test:prepare Execute test:units ENV LOADED !

I tried to test with rails edge too (changing Gemfile to use gem 'rails', :git => 'git://github.com/rails/rails.git'), and i got an error:

Trying to clean the previous message

I tested with rails 3.0.4, created an empty application and scaffold of users.
With a "puts" in config/environment.rb, i did:

rake test -t

I tried to test with rails edge too (changing Gemfile to use gem 'rails', :git => 'git://github.com/rails/rails.git'), and i got an error.

Put the output at gist: https://gist.github.com/829168

Looking at source, i realized two things:
1. https://github.com/rails/rails/blob/master/railties/lib/rails/appli... Rails, raises exception if application is already initialized.
2. Task test ( https://github.com/rails/rails/blob/master/railties/lib/rails/test_... ) invokes "test:units test:functionals test:integration". I think they are running in different process.

Somebody can help me ?

Hi Roger,

I'm not running into any problems running the test suite on the rails master branch -- can you try doing this again?

Thanks,
Chris

Roger,

Keep in mind if you are running edge rails, you need to be running edge rack as well, which is probably why you are getting the SessionHash error.

I didn't know about edge rack ...
Sorry for the false positive.

Thanks for the tip Christopher! It worked.
