rubocoprspec

rubocop-rspec is a RuboCop extension that adds a collection of cops focused on Ruby's RSpec test suite. It integrates with RuboCop to analyze test files and enforce consistent style and common best practices within RSpec examples, groups, and helpers. The project is community-maintained and widely used in Ruby projects to improve readability and reduce common test smells.

The cops cover areas such as the structure of describe and context blocks, the preferred usage of test data definitions (let, let!, subject), the style of expectations (preferring the expect syntax over older should syntax), and the proper use of doubles, mocks, and stubs. It also includes checks for shared examples, metadata usage, and issues related to hooks and example order. When offenses are detected, rubocop-rspec can often auto-correct a portion of them.

Installation typically involves adding rubocop-rspec to your Gemfile and running bundle install, or installing the gem directly. In the RuboCop configuration file, you enable or require the extension by adding rubocop-rspec so its cops are loaded and available to run. You can then enable, disable, or customize individual cops under the RSpec namespace to fit your project’s conventions. Running rubocop will report offenses from both RuboCop’s core cops and rubocop-rspec cops.

rubocop-rspec is compatible with recent RuboCop releases and Ruby versions used by Rails and other Ruby projects. It is maintained by the community with periodic releases and compatibility updates. For detailed information about the full list of cops and configuration options, refer to the project repository and its documentation.
