The Golang client library to stub API resources in WireMock using its REST API. The project connects to the instance and allows setting up stubs and response templating, or using administrative API to extract observability data.

The library was tested with the following distributions of WireMock:
- WireMock 2.x - standalone deployments, including but not limited to official Docker images, Helm charts and the Java executable
- WireMock 3.x Beta - partial support, some features are yet to be implemented. Contributions are welcome!
- WireMock Cloud - proprietary SaaS edition by WireMock Inc.
Note that the CI pipelines run only against the official community distributions of WireMock. It may work for custom builds and other distributions. Should there be any issues, contact their vendors/maintainers.
Launch a standalone Docker instance:
docker run -it --rm -p 8080:8080 wiremock/wiremock
Connect to it using the client library:
package main
import (
"net/http"
"testing"
"github.com/wiremock/go-wiremock"
)
func TestSome(t *testing.T) {
wiremockClient := wiremock.NewClient("https://0.0.0.0:8080")
defer wiremockClient.Reset()
// stubbing POST https://0.0.0.0:8080/example
wiremockClient.StubFor(wiremock.Post(wiremock.URLPathEqualTo("/example")).
WithQueryParam("firstName", wiremock.EqualTo("John")).
WithQueryParam("lastName", wiremock.NotMatching("Black")).
WithBodyPattern(wiremock.EqualToJson(`{"meta": "information"}`)).
WithHeader("x-session", wiremock.Matching("^\\S+fingerprint\\S+$")).
WithBearerToken(wiremock.StartsWith("token")).
WillReturnResponse(
wiremock.NewResponse().
WithJSONBody(map[string]interface{}{
"code": 400,
"detail": "detail",
}).
WithHeader("Content-Type", "application/json").
WithStatus(http.StatusBadRequest),
).

// scenario
defer wiremockClient.ResetAllScenarios()
wiremockClient.StubFor(wiremock.Get(wiremock.URLPathEqualTo("/status")).
WillReturnResponse(
wiremock.NewResponse().

WithHeader("Content-Type", "application/json").
WithStatus(http.StatusOK),

InScenario("Set status").
WhenScenarioStateIs(wiremock.ScenarioStateStarted))
wiremockClient.StubFor(wiremock.Post(wiremock.URLPathEqualTo("/state")).
WithBodyPattern(wiremock.EqualToJson(`{"status": "started"}`)).
InScenario("Set status").

wiremockClient.StubFor(statusStub)
//testing code...
