MockIt (open source) vs Pact: What are the differences?

Introduction

MockIt and Pact are both tools used in testing APIs, but they have significant differences in their approach and functionality.

  1. License: MockIt is an open-source tool, which means it is free for anyone to use and modify. Pact, on the other hand, is a commercial tool with a subscription-based pricing model.

  2. Collaboration: MockIt allows for collaboration within a team by enabling multiple developers to contribute to the mock data. Pact, however, focuses on collaboration between service providers and consumers by ensuring that API contracts are agreed upon and verified.

  3. Mocking Approach: MockIt provides a more flexible approach to mocking APIs, allowing users to customize responses based on various parameters. Pact, on the other hand, follows a strict contract-based approach where the responses are predetermined based on the defined contracts.

  4. Language Support: MockIt supports a wide range of programming languages for creating mock APIs, making it versatile for different technology stacks. Pact primarily focuses on supporting languages commonly used in microservices architectures such as Java, Ruby, and JavaScript.

  5. Integration Testing: MockIt is mainly used for unit testing and development purposes, while Pact is designed for contract testing between services to ensure compatibility and reliability.

  6. Documentation: MockIt provides comprehensive documentation and examples to help users get started quickly. Pact also offers detailed documentation but places more emphasis on the creation and verification of contracts between services.

In Summary, MockIt and Pact differ in licensing, collaboration, mocking approach, language support, testing focus, and documentation emphasis.

Stop wasting time mocking APIs. MockIt gives you an interface to configure and create REAL mocked end points for your applications.

It is a code-first tool for testing HTTP and message integrations using contract tests. Contract tests assert that inter-application messages conform to a shared understanding that is documented in a contract. Without contract testing, the only way to ensure that applications will work correctly together is by using expensive and brittle integration tests.

Live reload on server; Quickly create, edit & delete HTTP end-points; CORS enabled; Auth; Quick setup
Support for JavaScript, JVM, .NET, Python, Go, Ruby, PHP, Swift and more; Get fast, reliable feedback on the compatibility of your integrations; Ensures all your services are compatible with each other before you deploy
