Introducing WireMock.NET: Master HTTP API Testing

WireMock.NET simulates HTTP API behaviors, enabling seamless integration and testing for developers.

Ideal Use Cases:

• HTTP Dependencies Not Ready: Leap over the hurdle of incomplete HTTP APIs in microservice architectures by mimicking their behavior with WireMock.Net.

• Unit Testing HTTP-Dependent Classes: Test classes that rely on HTTP APIs as a cohesive unit, ensuring your code communicates effectively with the actual APIs.

• Integration/End-to-End Tests: Overcome the challenges of testing with external HTTP APIs—like variable data, slow responses, and network restrictions—by employing WireMock.Net for consistent and swift testing.


public class ExternalService(HttpClient httpClient)
{
public async Task GetAsync()
{
var response = await httpClient.GetAsync("/ping");
response.EnsureSuccessStatusCode();

return await response.Content.ReadAsStringAsync();
}
}

public class ExternalServiceTests
{
[Fact]
public async Task GetAsync_WhenCalled_ReturnsString()
{
// Arrange
var fakeServer = WireMockServer.Start();

fakeServer
.Given(Request.Create().WithPath("/ping").UsingGet())
.RespondWith(Response.Create()
.WithStatusCode(200)
.WithBody("pong")
);

var fakeClient = fakeServer.CreateClient();
var externalService = new ExternalService(fakeClient);

// Act
var response = await externalService.GetAsync();

// Assert
response.Should().Be("pong");
}
}
