xUnit Orderer is an implementation of ITestCaseOrderer enforcing xUnit to run the facts in strict order.

There're some scenarios that you might need to chain the facts to be evaluated in a strict order. This project implements the ITestCaseOrderer interface of xUnit and provides the TestPriority decorator to perform the test case ordering.

Check out the example below for details.

Packages in this project depend on

• xUnit v2.2.0

Older versions contain outdated dependencies, might produce errors.

You can install xUnit Orderer by running following commands in the Package Manager Console

Install-Package XunitOrderer

using System.Reflection;
using System.Runtime.InteropServices;
using Xunit;

...

[assembly:CollectionBehavior(DisableTestParallelization = true)]
[assembly:TestCollectionOrderer("XunitOrderer.TestCollectionOrderer", "XunitOrderer.Testing")]

[TestPriority(10)]
public class TestClass1 : TestClassBase
{
    [Fact]
    [TestPriority(101)]
    public void First()
    {
        Assert.Equal(1, 1);
    }
 
    [Fact]
    [TestPriority(102)]
    public void Second()
    {
        Assert.Equal(2, 2);
    }
}

[TestPriority(20)]
public class TestClass2 : TestClassBase
{
    [Fact]
    [TestPriority(103)]
    public void Third()
    {
        Assert.Equal(3, 3);
    }
 
    [Fact]
    [TestPriority(104)]
    public void Fourth()
    {
        Assert.Equal(4, 4);
    }
}

The execution order of the facts are:

• TestClass1 -> First
• TestClass1 -> Second
• TestClass2 -> Third
• TestClass2 -> Fourth

Built with .NET Framework v4.6.2, solution currently supports xUnit v2.2.0.
