Shoulda Matchers

• Good for testing associations
• Good for testing validations for presence of the application

Factory Bot

• Good for making a group of data similar to fixtures, but with non-fixed data.
• This applies a bit of randomness to the testing to be sure your tests are working properly.

$email = "test@mail.com" 
$valid_email = "test@mail.school.edu" 
$valid_email_2 = "test@mail.edu" 

$email_regex = /\A[\w+\-.]+@[a-z\d\-]+(\.[a-z\d\-]+)*\.[edu]+\z/i


$no_match =  $email_regex.match $email
$valid_match = $email_regex.match $valid_email

Recover MySQL root password

You can recover a MySQL database server password with the following five easy steps:

1. Stop the MySQL server process.
2. Start the MySQL (mysqld) server/daemon process with the --skip-grant-tables option so that it will not prompt for a password.
3. Connect to the MySQL server as the root user.
4. Set a new root password.
5. Exit and restart the MySQL server.
