XUnitAssured.Http 5.0.0

XUnitAssured.Net

XUnitAssured.Net is a fluent testing framework for .NET that helps developers create and maintain test collections with the goal of promoting the development of quality software products. Write expressive integration tests using a natural Given().When().Then() DSL for both HTTP/REST APIs and Apache Kafka.

🎯 Features

• Fluent BDD DSL: Write tests in a natural, readable way using Given().When().Then() syntax
• HTTP Testing: Comprehensive HTTP/REST API testing with full CRUD support, JSON path assertions, and schema validation
• Kafka Testing: Integration testing with Apache Kafka — produce/consume single and batch messages with header and key support
• Modular Architecture: Install only what you need (Core, Http, Kafka)
• Multiple HTTP Auth Types: Bearer, BearerWithAutoRefresh, Basic, OAuth2 (Client Credentials, Password, Authorization Code), API Key (Header/Query), Certificate (mTLS), Custom Headers
• Multiple Kafka Auth Types: SASL/PLAIN, SASL/SCRAM-SHA-256, SASL/SCRAM-SHA-512, SSL, Mutual TLS (mTLS)
• Automatic Authentication: Configure auth once in testsettings.json and have it applied automatically to every request
• Dependency Injection: Built-in DI support via DITestFixture base class
• Validation & BDD Extensions: ValidationBuilder and BDD scenario extensions consolidated in Core
• Multi-target Support: Targets net7.0, net8.0, net9.0, and net10.0
• xUnit Integration: Seamless integration with xUnit's fixtures and dependency injection

🚀 Quick Start

HTTP Testing

dotnet add package XUnitAssured.Http

using XUnitAssured.Http.Extensions;
using XUnitAssured.Http.Testing;

public class MyApiTests : HttpTestBase<MyTestFixture>, IClassFixture<MyTestFixture>
{
    public MyApiTests(MyTestFixture fixture) : base(fixture) { }

    [Fact]
    public void Get_Users_Returns_Success()
    {
        Given()
            .ApiResource("/api/users")
            .Get()
        .When()
            .Execute()
        .Then()
            .AssertStatusCode(200)
            .AssertJsonPath<string>("$.name", value => value == "John", "Name should be John");
    }
}

HTTP Authentication Examples

// Bearer Token
Given().ApiResource("/api/secure")
    .WithBearerToken("my-jwt-token")
    .Get()
.When().Execute()
.Then().AssertStatusCode(200);

// Basic Auth
Given().ApiResource("/api/secure")
    .WithBasicAuth("username", "password")
    .Get()
.When().Execute()
.Then().AssertStatusCode(200);

// API Key (Header or Query)
Given().ApiResource("/api/secure")
    .WithApiKey("X-API-Key", "my-api-key", ApiKeyLocation.Header)
    .Get()
.When().Execute()
.Then().AssertStatusCode(200);

// OAuth2 Client Credentials
Given().ApiResource("/api/secure")
    .WithOAuth2ClientCredentials("https://auth.example.com/token", "client-id", "client-secret")
    .Get()
.When().Execute()
.Then().AssertStatusCode(200);

Kafka Testing

dotnet add package XUnitAssured.Kafka

using XUnitAssured.Kafka.Extensions;
using XUnitAssured.Kafka.Testing;

public class MyKafkaTests : KafkaTestBase<KafkaClassFixture>, IClassFixture<KafkaClassFixture>
{
    public MyKafkaTests(KafkaClassFixture fixture) : base(fixture) { }

    [Fact]
    public void Produce_And_Consume_Message()
    {
        var topic = GenerateUniqueTopic("my-test");
        var groupId = $"test-{Guid.NewGuid():N}";

        // Produce
        Given()
            .Topic(topic)
            .Produce("Hello, Kafka!")
        .When()
            .Execute()
        .Then()
            .AssertSuccess();

        // Consume
        Given()
            .Topic(topic)
            .Consume()
            .WithGroupId(groupId)
        .When()
            .Execute()
        .Then()
            .AssertSuccess()
            .AssertMessage<string>(msg => msg.ShouldBe("Hello, Kafka!"));
    }
}

Kafka Batch Operations

// Produce batch
Given()
    .Topic("my-topic")
    .ProduceBatch(messages)
.When()
    .Execute()
.Then()
    .AssertSuccess()
    .AssertBatchCount(5);

// Consume batch
Given()
    .Topic("my-topic")
    .ConsumeBatch(5)
    .WithGroupId(groupId)
.When()
    .Execute()
.Then()
    .AssertSuccess()
    .AssertBatchCount(5);

Kafka Authentication Examples

// SASL/PLAIN
Given().Topic("my-topic")
    .Produce("message")
    .WithBootstrapServers("localhost:29093")
    .WithAuth(auth => auth.UseSaslPlain("user", "password", useSsl: false))
.When().Execute()
.Then().AssertSuccess();

// SSL (one-way)
Given().Topic("my-topic")
    .Produce("message")
    .WithBootstrapServers("localhost:29096")
    .WithAuth(auth => auth.UseSsl("certs/ca-cert.pem"))
.When().Execute()
.Then().AssertSuccess();

// Mutual TLS (mTLS)
Given().Topic("my-topic")
    .Produce("message")
    .WithBootstrapServers("localhost:29097")
    .WithAuth(auth => auth.UseMutualTls("client-cert.pem", "client-key.pem", "ca-cert.pem"))
.When().Execute()
.Then().AssertSuccess();

🏗️ Architecture

XUnitAssured.Core  (DSL + Abstractions + DI + ValidationBuilder + BDD Extensions)
       ↓                              ↓
XUnitAssured.Http             XUnitAssured.Kafka
(HTTP/REST Testing)           (Kafka Integration Testing)

Design Principles:

• SOLID: Each package has a single responsibility
• KISS: Simple, straightforward APIs
• DRY: Reusable components across tests
• YAGNI: Only what you need, when you need it
• Separation of Concerns: Clear boundaries between HTTP, Kafka, and Core
