What is Test-Driven Development in Rails?

Test-Driven Development (TDD) in Rails is a software development process where tests are written before the actual code. It helps ensure that the code meets the requirements and works as expected.

How do I get started with TDD in a Rails project?

To start with TDD in Rails, you can follow these steps: 1. Set up your Rails environment. 2. Write a test for a feature you want to implement. 3. Run the test to see it fail. 4. Write the minimum code necessary to pass the test. 5. Refactor the code and repeat.

What testing frameworks are commonly used with Rails?

Common testing frameworks for Rails include RSpec, Minitest, and Capybara for integration testing. RSpec is particularly popular for its expressive syntax.

Can you give me an example of a simple test in RSpec?

Sure! Here's a simple RSpec test for a model:

RSpec.describe User, type: :model do
  it 'is valid with valid attributes' do
    user = User.new(name: 'John', email: '[email protected]')
    expect(user).to be_valid
  end
end
