What are some useful Rails gems for testing?
There are several great gems for testing in Rails, such as RSpec for behavior-driven development, Capybara for integration testing, and FactoryBot for setting up test data.
Can you explain how to set up RSpec in a Rails project?
Sure! To set up RSpec, add it to your Gemfile: gem 'rspec-rails'
. Then run bundle install
and execute rails generate rspec:install
to create the necessary files.
What is Capybara used for?
Capybara is used for simulating how a user would interact with your application. It allows you to write tests that mimic user actions like clicking links and filling out forms.
Are there any gems for testing APIs?
Yes! You can use gems like 'RSpec API Documentation' for generating API documentation and 'VCR' for recording HTTP interactions in your tests.
