timewarp-fixie

TimeWarp Logo

Fixie is a dotnet test framework similar to NUnit and xUnit, but with an emphasis on low-ceremony defaults and flexible customizations.

TimeWarp-fixie is a project that uses conventions to simplify using Fixie even further.

Feature overview

  • Dependency Injection support for test cases.
  • No need to decorate test methods with [Test] attributes. Public methods are test cases by default.
  • Skip - can mark tests to be skipped.
  • Tags - Add tags to your tests and filter runs based on the tag.
  • Inputs - Allow for parameterized tests. (similar to how "Theory" works in xUnit)
  • Lifecycle Methods - if the Setup or Cleanup methods are found on the test class they will be executed appropriately.
  • NotTest - Can mark methods with NotTest attribute if they are not tests.
  • Filter tests by name
  • Filter tests by Tags

Installation

You can see the latest NuGet packages from the official TimeWarp NuGet page.

Usage

Creating a New Test Project

Create a new test project:

dotnet new classlib -n MyProject.Tests

Add NuGet packages to the project:

dotnet add package TimeWarp.Fixie
dotnet add package Fixie.TestAdapter

Create a dotnet tool manifest:

dotnet new tool-manifest

Add Fixie.Console to the manifest:

dotnet tool install Fixie.Console

Configuring Testing Convention

Inside your Fixie project, create a class that inherits from Fixie.Conventions.TestingConvention:

class TestingConvention : TimeWarp.Fixie.TestingConvention { }

This will use the TimeWarp.Fixie convention.

Configuring Services for the Execution Phase

To customize the services used in the execution phase, inherit from TestingConvention and override the service configuration:

namespace TimeWarp.Architecture.Testing;

public class TimeWarpTestingConvention : TestingConvention
{
    public TimeWarpTestingConvention() : base(ConfigureAdditionalServicesCallback) { }

    private static void ConfigureAdditionalServicesCallback(ServiceCollection serviceCollection)
    {
        Console.WriteLine("ConfigureAdditionalServices");
        serviceCollection
            .AddSingleton<WebTestServerApplication>()
            .AddSingleton<ApiTestServerApplication>()
            .AddSingleton<SpaTestApplication<YarpTestServerApplication, TimeWarp.Architecture.Yarp.Server.Program>>()
            .AddSingleton<YarpTestServerApplication>();
    }
}

Creating a Sample Test

First, add FluentAssertions (you could use basic Asserts or any other assertion library):

dotnet add package FluentAssertions

Create a sample test class named ConventionTests.cs:

namespace ConventionTest_;

using FluentAssertions;
using TimeWarp.Fixie;

[TestTag(TestTags.Fast)]
public class SimpleNoApplicationTest_Should_
{
    public static void AlwaysPass() => true.Should().BeTrue();

    [Skip("Demonstrates skip attribute")]
    public static void SkipExample() => true.Should().BeFalse();

    [TestTag(TestTags.Fast)]
    public static void TagExample() => true.Should().BeTrue();

    [Input(5, 3, 2)]
    [Input(8, 5, 3)]
    public static void Subtract(int aX, int aY, int aExpectedDifference)
    {
        int result = aX - aY;
        result.Should().Be(aExpectedDifference);
    }
}

Executing the Tests

dotnet fixie

Features

Dependency Injection

Tests are instantiated from the dependency injection container set up for tests, so you can use the same pattern for testing as for production apps.

No Need to Decorate Test Methods with [Test] Attributes

Public methods are test cases by convention:

// Xunit style
[Test] // <==== Not needed with TimeWarp Fixie Convention
public void SomeTest()
{
    Assert.Fail();
}
// TimeWarp Fixie Convention: all public methods are tests 
public void SomeTest()
{
    Assert.Fail();
}

Skip - Mark Tests to Be Skipped

[Skip("Reason for skipping")]
public static void SkipExample() => true.Should().BeFalse();

Tags

You can add tags to any of your tests. We include some in the TestTags static class, but they are just strings, so you can add whatever you like:

[TestTag(TestTags.Fast)]
[TestTag("Bug123")]
public static void TagExample() => true.Should().BeTrue();

Parameterized Tests

Similar to how xUnit uses [Theory], you can run a test for each set of parameters:

[Input(5, 3, 2)]
[Input(8, 5, 3)]
public static void Subtract(int aX, int aY, int aExpectedDifference)
{
    int result = aX - aY;
    result.Should().Be(aExpectedDifference);
}

Lifecycle Methods

If the Setup or Cleanup methods are found on the test class, they will be executed appropriately for each test:

public class LifecycleExamples
{
    public static void AlwaysPass() => true.Should().BeTrue();

    [Input(5, 3, 2)]
    [Input(8, 5, 3)]
    public static void Subtract(int aX, int aY, int aExpectedDifference)
    {
        // Will run lifecycles around each Input
        int result = aX - aY;
        result.Should().Be(aExpectedDifference);
    }

    public static void Setup() => Console.WriteLine("Sample Setup");
    public static void Cleanup() => Console.WriteLine("Sample Cleanup");
}

NotTest

If you have a class that needs to be public but does not contain tests, you can mark it as such with the [NotTest] attribute. For example:

[NotTest]
[AttributeUsage(AttributeTargets.Class, AllowMultiple = false)]
public class NotTest : Attribute { }

Filtering Tests by Name

From Fixie's docs:

The optional argument --tests (abbreviated -t) lets you specify which tests to run.
