Testing API Name Resolution Capabilities in ruby-grape/grape

This test suite validates the naming functionality in Grape API, specifically focusing on endpoint identification and API class naming capabilities. It ensures proper handling of named API instances and verifies the ability to access API names at runtime.

Test Coverage Overview

The test suite provides coverage for Grape API’s naming mechanisms, focusing on endpoint options and class name resolution.

Key areas tested include:

API endpoint name accessibility
Class name constant handling
Runtime API name resolution
Endpoint options validation

Implementation Analysis

The testing approach utilizes RSpec’s subject and let blocks to establish isolated test contexts. It implements stub_const for class name definition and leverages Grape’s endpoint options inspection.

Notable patterns include:

Dynamic API class creation
Constant stubbing for name testing
Endpoint options extraction
Class inheritance verification

Technical Details

Testing infrastructure includes:

RSpec testing framework
Grape API framework
Ruby constant manipulation
Dynamic class generation
Endpoint configuration testing

Best Practices Demonstrated

The test demonstrates several quality testing practices including isolation of test subjects, clear arrangement of test components, and explicit expectation setting.

Key practices include:

Subject definition for focused testing
Helper method usage for setup
Clean test organization
Explicit test descriptions
