Mocking a server with GraphQL tools has become significantly easier, thanks to the introduction of type systems. This allows for faster and more convenient mocking of backend APIs, making it possible to start developing frontend features without a working backend, run tests locally without connecting to a real backend, and even customize mock data to suit specific needs. The Apollo mocking tool provides a simple way to create mock servers with just one line of code, using the GraphQL schema as a reference point. With this tool, developers can quickly get started with mocking their backend APIs and fine-tune their mocks in tiny steps as needed.
