apply xUnit testing patterns for DataFactory

Published by Microsoft Updated May 13

Covers QA Microsoft MCP Engineering Testing

Description

xUnit testing patterns and conventions for DataFactory.MCP. Use when writing tests, fixing test failures, or adding test coverage.

SKILL.md

Testing in DataFactory.MCP

Test Stack

Framework: xUnit ([Fact], [Theory], [InlineData])
Runner: xunit.runner.visualstudio
Skippable: Xunit.SkippableFact ([SkippableFact], Skip.If(...))
Coverage: coverlet
Target: net10.0

Test Location

All tests live in DataFactory.MCP.Tests/.

Commands

Task	Command
Run all	`dotnet test`
Verbose	`dotnet test -v normal`
Filter	`dotnet test --filter "FullyQualifiedName~TestName"`
Coverage	`dotnet test --collect:"XPlat Code Coverage"`

Naming Convention

MethodName_Scenario_ExpectedResult

Examples:

Authenticate_WithValidCredentials_ReturnsToken
ListGateways_WhenNotAuthenticated_ThrowsException
CreateConnection_WithInvalidType_ReturnsError

Test Patterns

Unit Test (Arrange-Act-Assert)

public class MyServiceTests
{
    [Fact]
    public void MethodName_Scenario_ExpectedResult()
    {
        // Arrange
        var service = new MyService();

        // Act
        var result = service.DoSomething();

        // Assert
        Assert.NotNull(result);
        Assert.Equal("expected", result.Value);
    }
}

Parameterized Tests

[Theory]
[InlineData("input1", "expected1")]
[InlineData("input2", "expected2")]
public void MethodName_WithVariousInputs_ReturnsExpected(string input, string expected)
{
    var result = MyService.Process(input);
    Assert.Equal(expected, result);
}

Skippable Tests (for environment-dependent tests)

[SkippableFact]
public void IntegrationTest_RequiresAuth()
{
    Skip.If(string.IsNullOrEmpty(Environment.GetEnvironmentVariable("AZURE_CLIENT_ID")),
        "Requires Azure credentials");
    // test body
}

What to Test

Tools: Parameter validation, response formatting, error handling
Services: API call construction, response parsing, error translation
Models: Serialization/deserialization roundtrips
Edge cases: Null inputs, empty collections, unauthenticated state, API errors

Evaluation Scenarios

Reference evals/ for integration test scenarios:

authentication.eval.md, connections.eval.md, dataflows.eval.md
gateways.eval.md, pipelines.eval.md, multi-step.eval.md
