rails create database only in test

To create a database only in the test environment using Ruby on Rails, follow these steps:

  1. Open your Rails project in a code editor.

  2. Navigate to the config folder in your project's root directory.

  3. Open the database.yml file.

  4. Inside the database.yml file, you will find a section for the test environment. It typically looks like this:

test:
  <<: *defaults
  database: your_app_name_test
  1. Under the database key, specify the name you want to give to your test database. Replace your_app_name_test with the desired name. For example, if you want to name your test database my_app_test, the updated section should look like this:
test:
  <<: *defaults
  database: my_app_test
  1. Save the database.yml file.

  2. Next, open your terminal or command prompt and navigate to your project's root directory.

  3. Run the following command to create the test database:

rails db:create RAILS_ENV=test
  1. After executing the command, Rails will create a new database with the specified name in the test environment.

  2. You can verify that the test database has been created by running the following command:

rails dbconsole RAILS_ENV=test
  1. This will open a database console for the test environment, allowing you to perform database operations specific to the test environment.

That's it! You have successfully created a database only in the test environment using Ruby on Rails.
