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

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

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

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

WireMock.Net can be used in several ways:

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

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