rspec

RSpec test structure best practices involve organizing top-level describe blocks by class, nesting context blocks for conditions, and grouping let, subject, and before blocks at the top for consistency. This improves test readability and maintainability.

In Ruby specs, use let and let! for lazy and pre-evaluated memoization respectively, and utilize named subjects to improve readability. This ensures robust and maintainable test setup across unit and integration tests.

You should use the expect syntax in Rails testing instead of the older should syntax. The expect syntax is the established standard promoted by the RSpec Style Guide for writing clear and robust expectations.

You need verified doubles in RSpec integration tests to prevent stubbed methods from becoming out of sync with actual implementations. Using verified doubles is a best practice that makes your test suite more robust.

Yes, you can apply RSpec style guides to request specs, model specs, and integration tests. The guidelines help structure describe/context blocks and enforce proper matcher usage across all Ruby and Rails test types.

Better Specs focuses on formatting and structural conventions for Ruby testing, such as let placement and context nesting. It provides guidance rather than automated linting, requiring manual application of style patterns to your test suite.
