WireMock.Net

Lightweight Http Mocking Server for .NET, inspired by WireMock.org (from the Java landscape).

:star: Key Features

• HTTP response stubbing, matchable on URL/Path, headers, cookies and body content patterns
• Library can be used in unit tests and integration tests
• Runs as a standalone process, as windows service, as Azure/IIS or as docker
• Configurable via a fluent C# .NET API, JSON files and JSON over HTTP
• Record/playback of stubs (proxying)
• Per-request conditional proxying
• Stateful behaviour simulation
• Response templating / transformation using Handlebars and extensions
• Can be used locally or in CI/CD scenarios
• Can be used for Aspire Distributed Application testing

:star: Stubbing

A core feature of WireMock.Net is the ability to return predefined HTTP responses for requests matching criteria. See Wiki : Stubbing.

:star: Request Matching

WireMock.Net support advanced request-matching logic, see Wiki : Request Matching.

:star: Response Templating

The response which is returned WireMock.Net can be changed using templating. This is described here Wiki : Response Templating.

:star: Admin API Reference

The WireMock admin API provides functionality to define the mappings via a http interface see Wiki : Admin API Reference.

:star: Using

WireMock.Net can be used in several ways:

UnitTesting

You can use your favorite test framework and use WireMock within your tests, see Wiki : UnitTesting.

Unit/Integration Testing using Testcontainers.DotNet

See Wiki : WireMock.Net.Testcontainers on how to build a WireMock.Net Docker container which can be used in Unit/Integration testing.

Unit/Integration Testing using an an Aspire Distributed Application

See Wiki : WireMock.Net.Aspire on how to use WireMock.Net as an Aspire Hosted application to do Unit/Integration testing.

As a dotnet tool

It's simple to install WireMock.Net as (global) dotnet tool, see Wiki : dotnet tool.

As standalone process / console application

This is quite straight forward to launch a mock server within a console application, see Wiki : Standalone Process.

As a Windows Service

You can also run WireMock.Net as a Windows Service, follow this WireMock-as-a-Windows-Service.

As a Web Job in Azure or application in IIS

See this link WireMock-as-a-(Azure)-Web-App

In a docker container

There is also a Linux and Windows-Nano container available at hub.docker.com. For more details see also Docker.
