Rake aborted! Incorrect database name?

Question

I was hoping to run some unit tests but this is what I am getting. The internets are silent on the issue. Rails 2.1 Let me know if there is any other info that would help.

    mike@sleepycat:~/projects/myapp$ rake test:units --trace
    (in /home/mike/projects/myapp)
    ** Invoke test:units (first_time)
    ** Invoke db:test:prepare (first_time)
    ** Invoke environment (first_time)
    ** Execute environment
    ** Invoke db:abort_if_pending_migrations (first_time)
    ** Invoke environment 
    ** Execute db:abort_if_pending_migrations
    ** Execute db:test:prepare
    ** Invoke db:test:clone (first_time)
    ** Invoke db:schema:dump (first_time)
    ** Invoke environment 
    ** Execute db:schema:dump
    ** Invoke db:test:purge (first_time)
    ** Invoke environment 
    ** Execute db:test:purge
    rake aborted!

My database.yml:

    # MySQL (default setup).  Versions 4.1 and 5.0 are recommended.
    #
    # Install the MySQL driver:
    #   gem install mysql
    # On MacOS X:
    #   gem install mysql -- --include=/usr/local/lib
    # On Windows:
    #   gem install mysql
    #       Choose the win32 build.
    #       Install MySQL and put its /bin directory on your path.
    #
    # And be sure to use new-style password hashing:
    #   http://dev.mysql.com/doc/refman/5.0/en/old-client.html
    development:
      adapter: mysql

    # Warning: The database defined as 'test' will be erased and
    # re-generated from your development database when you run 'rake'.
    # Do not set this db to the same as development or production.

Answer 1

It looks like you haven't specified a database name for the test environment in your config/database.yml file.

Answer 2

cant end lines in comments so i'll just put it here

can you run script/console then do :

@a = YAML::load(File.open("#{RAILS_ROOT}/config/database.yml"))

@a

then paste the contents of @a
