RestSharp vs Pact: What are the differences?

Developers describe RestSharp as "Simple REST and HTTP API Client for .NET". It is probably the most popular HTTP client library for .NET. Featuring automatic serialization and deserialization, request and response type detection, variety of authentications and other useful features. On the other hand, Pact is detailed as "Fast, easy and reliable testing for your APIs and microservices during development". 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.

RestSharp can be classified as a tool in the "API Tools" category, while Pact is grouped under "Microservices Tools".

Some of the features offered by RestSharp are:

• Serialization
• Sync and Async
• Extensive configuration

On the other hand, Pact provides the following key features:

• 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
