我在这里有点难过。我已经创建了一个数据库，并且使用depot_production数据库没有任何问题。但是，最近每当进行rake测试时，我都会收到很多错误，例如

# Running tests:

EEEEEEEE

Finished tests in 0.031499s, 253.9763 tests/s, 0.0000 assertions/s.

1) Error:
test_should_create_product(ProductsControllerTest):
Mysql2::Error: Access denied for user 'test'@'localhost' to database 'depot_test'

奇怪的是，我认为我的database.yml文件很好。每次我运行db：migrate时，我都会得到一个空行。我还添加了一个用户测试，但我认为仅将其添加到我的开发数据库中。我认为我的测试，生产和数据库不存在…

development:
adapter: mysql2
encoding: utf8
reconnect: false
database: depot_development
pool: 5
username: root
password: admin
socket: /tmp/mysql.sock

# 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.
test:
adapter: mysql2
encoding: utf8
reconnect: false
database: depot_test
pool: 5
username: test
password: testy
socket: /tmp/mysql.sock

production:
adapter: mysql2
encoding: utf8
reconnect: false
database: depot_production
pool: 5
username: prod
password: mypassword
socket: /tmp/mysql.sock

任何建议，将不胜感激，谢谢。

感谢您在这里陪伴我。我感觉自己很近，但是有些奇怪。这是我所做的。
