ZeroMcp.TestKit.Xunit

xUnit integration for ZeroMcp.TestKit — test MCP (Model Context Protocol) servers with first-class Visual Studio Test Explorer support.

Install

dotnet add package ZeroMcp.TestKit.Xunit

This package depends on ZeroMcp.TestKit (installed automatically).

Attributes

[McpFact]

Marks a test as an MCP server test. Inherits from xUnit's [Fact].

using ZeroMcp.TestKit;
using ZeroMcp.TestKit.Xunit;

public class MyMcpServerTests
{
    [McpFact(DisplayName = "search returns valid schema")]
    public async Task SearchToolSchemaValid()
    {
        await McpTest
            .Server("http://localhost:8000/mcp")
            .Tool("search")
                .WithParams(new { query = "hello" })
                .ExpectSchemaMatch()
            .RunAsync();
    }
}

[McpTheory]

Parameterized MCP tests. Inherits from xUnit's [Theory].

[McpTheory(DisplayName = "Lookup tools return valid schema")]
[InlineData("get_customer", 1)]
[InlineData("get_product", 1)]
[InlineData("get_order", 1)]
public async Task LookupById_SchemaValid(string toolName, int id)
{
    await McpTest
        .Server("http://localhost:8000/mcp")
        .Tool(toolName)
            .WithParams(new { id })
            .ExpectSchemaMatch()
        .RunAsync();
}

McpAssert — Static Assertion Helpers

var result = await McpTest
    .Server("http://localhost:8000/mcp")
    .Tool("search").WithParams(new { query = "hi" })
    .RunWithoutThrowAsync();

McpAssert.Passed(result);
McpAssert.ToolPassed(result, "search");
McpAssert.SchemaValid(result, "search");
McpAssert.Deterministic(result, "search");
McpAssert.ResponseHasProperty(result, "search", "name");
McpAssert.ResponseContains(result, "search", "name", "Alice");

Fluent Assertion Chains

Scope to a specific tool with ForTool(), then chain assertions:

var result = await McpTest
    .Server("http://localhost:8000/mcp")
    .Tool("get_customer").WithParams(new { id = 1 })
    .RunWithoutThrowAsync();

result.ForTool("get_customer")
    .Passed()
    .HasValidSchema()
    .HasReturnProperty("id")
    .HasReturnProperty("name")
    .HasReturnValue("email", "alice@example.com");

Available Fluent Methods

Method	Asserts
`.Passed()`	Tool test passed
`.Failed()`	Tool test failed
`.HasToolName(name)`	Tool name matches
`.HasValidSchema()`	Schema validation passed
`.IsDeterministic()`	Determinism check passed
`.HasReturnProperty(path)`	Response payload contains the property
`.HasReturnValue(path, value)`	Response payload property equals the value
