How do I write tests in Ruby on Rails?

In Ruby on Rails, you can write tests using the built-in testing framework. You typically create test files in the test directory.

What types of tests can I write?

You can write unit tests, functional tests, and integration tests. Each serves a different purpose in testing your application.

Can you show me an example of a unit test?

Sure! Here's a simple example:

require 'test_helper'

class UserTest < ActiveSupport::TestCase
  test 'valid user' do
    user = User.new(name: 'John Doe', email: '[email protected]')
    assert user.valid?
  end
end

This tests that a user is valid with a name and email.

How do I run my tests?

You can run your tests using the command rails test in your terminal. This will execute all tests in your application.
