MockAPI is a simple tool that lets you easily mock up APIs, generate custom data, and perform operations on it using RESTful interface. MockAPI is meant to be used as a prototyping/testing/learning tool.

February 28, 2024 - An API mock is a web service that simulates a real, functional service. A mock can be used to provide example responses from the backend service that is currently being developed, which makes it a great fit for the use case we described above.

February 5, 2026 - API mocking involves creating a simulated version of the real API to help testers carry on with their testing activities in case the actual API is not available

WireMock is a tool for building mock APIs. API mocking enables you build stable, predictable development environments when the APIs you depend on are unreliable or don’t exist.

Get working mock REST APIs in seconds with an intuitive and easy-to-use interface.

Web APIs are usually implemented as HTTP endpoints. Playwright provides APIs to mock and modify network traffic, both HTTP and HTTPS. Any requests that a page does, including XHRs and fetch requests, can be tracked, modified and mocked.

August 18, 2025 - Instead of sending requests to a live backend service, API mocking returns predefined responses, allowing developers and testers to work with the API’s expected behavior even if the real service is incomplete, unavailable, or still being developed.

Leverage native API mocking to create mocks with dynamic responses manually or automatically from OpenAPI specs, API responses or natural language.

Ensure that 200 OK, application/json appears in the API Management response box. This selection indicates that your API should return the response sample that you defined in the previous section. Select Save. ... A yellow bar displaying the text Mocking is enabled appears.

Learn how to quickly mock data to design, build, and test APIs using a mock or dummy API Server.

Testing your REST & SOAP APIs, both internal and external, is critical in producing quality software that works for the end user in a manner that it's supposed to. Learn the in's and out's of API testing.

Mock Service Worker is an API mocking library that allows you to write client-agnostic mocks and reuse them across any frameworks, tools, and environments.

December 1, 2025 - Developers can discover, subscribe, and test all your APIs (Edge Stack + Gravitee) from the same developer portal, simplifying onboarding and developer collaboration.

In this tutorial, you’ll learn how mock servers and examples work together and how to integrate them into your API workflow.

API mocking is the process of simulating API responses without relying on the actual backend server. It allows developers and testers to create mock responses to API calls, making development and testing faster, more flexible, and independent ...

API mocking is the practice of creating simulated responses to API requests, mimicking the behavior of a real backend. These mock APIs can return predefined data, simulate errors, or even replicate complex workflows like authentication and rate ...

March 25, 2024 - API mocking plays a critical role in software development to isolate the system under test, reducing dependencies across teams, and streamlining the entire testing process. In this blog, we discuss the benefits, drawbacks, and key use cases ...

easily set up mock responses independently for each test to ensure test data is encapsulated with each test. Avoid sharing data between tests that is difficult to manage and maintain and risks tests infecting each other · create test assertions that verify the requests the system-under-test has sent ... start working against a service API before the service is available.
