About:
Inso is the command-line interface for Insomnia, a popular API design and testing tool. It enables developers to run automated testing, linting, and spec validation for API definitions directly within CI/CD pipelines. This tool is essential for enforcing API standards and ensuring consistency across development workflows.
Key Features:
  • Run automated tests for OpenAPI and GraphQL specifications
  • Lint API definitions to enforce style guides and best practices
  • Execute test suites from the command line for seamless CI/CD integration
  • Generate code snippets for various languages and frameworks
Use Cases:
  • Integrating API contract testing into continuous integration pipelines
  • Validating OpenAPI specifications for correctness and consistency
  • Automating GraphQL schema checks as part of a development workflow
Alternatives:
  • newman – Postman's CLI runner, best suited for collections, whereas Inso is purpose-built for Insomnia's ecosystem and API specifications.
  • bruno – An open-source API client with a CLI, often seen as a direct alternative to Insomnia with a focus on file-based collections.
