Xunit.Extensions.TestDependency

Supports: .NET Core 1.x, .NET Core 2.x., .NET Core 3.x.* and .NET 4.6.1+ Works in parallel

So you want to have dependent tests

You should not do it, but here is how to do it.

• Xunit can order tests only within the same class.
  • Use partial classes to help keep tests organized.
• Classes can run in parellel against each other.
  • If using this with Selenium tests you will need to configure your WebDriver to have individual profiles per test else they will share the same instance.
• Test Name depends on the current DisplayName used by Xunit. If it is not set to method only then it expects the whole namespace with methodname.

Using

You can decorate the assembly or class using TestCaseOrderer

[assembly: TestCaseOrderer(DependencyOrderer.TypeName, DependencyOrderer.AssemblyName)]

[TestCaseOrderer(DependencyOrderer.TypeName, DependencyOrderer.AssemblyName)]
public class Example
{
  //tests here
}

Example from Project Unit Test:

[Trait("xUnit", "Ordered")]
[TestCaseOrderer(DependencyOrderer.TypeName, DependencyOrderer.AssemblyName)]
public partial class OrderTests 
{
    public static List<double> ExecutionOrder { get; set; } = new List<double>();

    [Fact]
    [TestDependency(nameof(OrderedTest1))]
    public void OrderedTest0()
    {
        ExecutionOrder.Add(0);
        Assert.Contains(1, ExecutionOrder);
        Assert.Contains(2.1, ExecutionOrder);
        Assert.Contains(2.2, ExecutionOrder);
        Assert.Contains(3, ExecutionOrder);
    }

    [Theory]
    [TestDependency(nameof(OrderedTest3))]
    [InlineData(2.1)]
    [InlineData(2.2)]
    public void OrderedTest2(double i)
    {

        ExecutionOrder.Add(i);
        Assert.DoesNotContain(0, ExecutionOrder);
        Assert.DoesNotContain(1, ExecutionOrder);
        Assert.Contains(3, ExecutionOrder);
    }
}

public partial class OrderTests
{
    [Fact]        
    public void OrderedTest3()
    {
        ExecutionOrder.Add(3);
        Assert.DoesNotContain(0, ExecutionOrder);
        Assert.DoesNotContain(1, ExecutionOrder);
        Assert.DoesNotContain(2.1, ExecutionOrder);
        Assert.DoesNotContain(2.2, ExecutionOrder);
    }

    [Fact]
    [TestDependency("OrderedTest2(i: 2.1)", "OrderedTest2(i: 2.2)")]
    public void OrderedTest1()
    {
        ExecutionOrder.Add(1);
        Assert.DoesNotContain(0, ExecutionOrder);
        Assert.Contains(2.1, ExecutionOrder);
        Assert.Contains(2.1, ExecutionOrder);
        Assert.Contains(2.2, ExecutionOrder);
        Assert.Contains(3, ExecutionOrder);
    }
}
