Mysql2::Error: Access denied for user 'test'@'localhost' to database 'depot_test'

Question

I am a bit stumped here. I have created a database and have had no issues using the depot_production database. However, of late whenever I run rake test, I get a bunch of errors like

# 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'

The odd thing is I think my database.yml file is fine. And everytime I run db:migrate I just get an empty line returned to me. I also added a user test, but I think that only added it to my development database. I sorta think my test and production and databases don't exist...

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

Any advice would be appreciated, thanks.

Thanks for sticking with me here. I feel like I am close but something is odd. Here is what I did.

Answer 1

So first login as root or whatever your root user is called from terminal.

mysql -u root -p

CREATE DATABASE depot_test

CREATE USER 'test'@'localhost' IDENTIFIED BY 'mypass123';

USE depot_test

Once you are logged in to mysql, grant privileges to the user test (remember to change password)

GRANT ALL privileges on depot_test.* to test@localhost identified by 'mypass123';

FLUSH PRIVILEGES;

You will need to change your pass to "mypass123" in your database.yml
