Use Microsoft.Extensions.DependencyInjection
to resolve xUnit test cases
How to use
Install the Nuget package.
dotnet add package Xunit.DependencyInjection
In your testing project, add the following framework
namespace Your.Test.Project
{
public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddTransient<IDependency, DependencyClass>();
}
}
}
Example test class
.
public interface IDependency
{
int Value { get; }
}
internal class DependencyClass : IDependency
{
public int Value => 1;
}
public class MyAwesomeTests
{
private readonly IDependency _d;
public MyAwesomeTests(IDependency d) => _d = d;
[Fact]
public void AssertThatWeDoStuff()
{
Assert.Equal(1, _d.Value);
}
}
Xunit.DependencyInjection
is built into the generic host and fully supports its lifecycle, allowing you to use all features supported by the generic host, including but not limited toIHostedService
.
Integration asp.net core TestHost(3.0+)
Asp.Net Core Startup
dotnet add package Microsoft.AspNetCore.TestHost
public class Startup
{
public void ConfigureHost(IHostBuilder hostBuilder) => hostBuilder
.ConfigureWebHost[Defaults](webHostBuilder => webHostBuilder
.UseTestServer(options => options.PreserveExecutionContext = true)
.UseStartup<AspNetCoreStartup>());
}
MinimalApi
If you use MinimalApi rather than asp.net core Startup class.
Add package reference for Xunit.DependencyInjection.AspNetCoreTesting
dotnet add package Xunit.DependencyInjection.AspNetCoreTesting
public class Startup
{
public IHostBuilder CreateHostBuilder() => MinimalApiHostBuilderFactory.GetHostBuilder<Program>();
}
Maybe your asp.net core project should InternalsVisibleTo or add
public partial class Program {}
in the end ofProgram.cs
;Detail see Xunit.DependencyInjection.Test.AspNetCore

How to find Startup
?
1. Specific startup
Declare [Startup] on test class
2. Nested startup
public class TestClass1
{
public class Startup
{
public void ConfigureServices(IServiceCollection services) { }
}
3. Closest startup
If the class type full name is "A.B.C.TestClass", find Startup in the following order:
-
A.B.C.Startup
-
A.B.Startup
-
A.Startup
-
Startup
4. Default startup
Default startup is required before 8.7.0, is optional in some case after 8.7.0.
If is required, please add a startup class in your test project.
Default is find Your.Test.Project.Startup, Your.Test.Project
.
If you want to use a special Startup
, you can define XunitStartupAssembly
and XunitStartupFullName
in the PropertyGroup
section
<Project>
<PropertyGroup>
<XunitStartupAssembly>Abc</XunitStartupAssembly>
<XunitStartupFullName>Xyz</XunitStartupFullName>
</PropertyGroup>
</Project>
XunitStartupAssembly | XunitStartupFullName | Startup |
---|---|---|
Your.Test.Project.Startup, Your.Test.Project | ||
Abc | Abc.Startup, Abc | |
Xyz | Xyz, Your.Test.Project | |
Abc | Xyz | Xyz, Abc |
Parallel
By default, xUnit runs all test cases in a test class synchronously. This package can extend the test framework to execute tests in parallel.
<Project>
<PropertyGroup>
<ParallelizationMode></ParallelizationMode>
</PropertyGroup>
</Project>
This package has two policies to run test cases in parallel.
-
Enhance or true
Respect xunit parallelization behavior.
-
Force
Ignore xunit parallelization behavior and force running tests in parallel.
If [Collection]
(if ParallelizationMode is not Force
), [CollectionDefinition(DisableParallelization = true)]
, [DisableParallelization]
declared on the test class, the test class will run sequentially. If [DisableParallelization]
, [MemberData(DisableDiscoveryEnumeration = true)]
declared on the test method, the test method will run sequentially.
It is recommended to use xunit 2.8.0+ and without setting parallelAlgorithm
How to disable Xunit.DependencyInjection
<Project>
<PropertyGroup>
<EnableXunitDependencyInjectionDefaultTestFrameworkAttribute>false</EnableXunitDependencyInjectionDefaultTestFrameworkAttribute>
</PropertyGroup>
</Project>
How to inject ITestOutputHelper
internal class DependencyClass : IDependency
{
private readonly ITestOutputHelperAccessor _testOutputHelperAccessor;
public DependencyClass(ITestOutputHelperAccessor testOutputHelperAccessor)
{
_testOutputHelperAccessor = testOutputHelperAccessor;
}
}
Write Microsoft.Extensions.Logging
to ITestOutputHelper
Add package reference for Xunit.DependencyInjection.Logging
dotnet add package Xunit.DependencyInjection.Logging
The call chain must be from the test case. If not, this feature will not work.
public class Startup
{
public void ConfigureServices(IServiceCollection services) => services
.AddLogging(lb => lb.AddXunitOutput());
}
How to inject IConfiguration
or IHostEnvironment
into Startup
?
public class Startup
{
public void ConfigureHost(IHostBuilder hostBuilder) => hostBuilder
.ConfigureServices((context, services) => { context.XXXX });
}
or
public class Startup
{
public void ConfigureServices(IServiceCollection services, HostBuilderContext context)
{
context.XXXX;
}
}
How to configure IConfiguration
?
public class Startup
{
public void ConfigureHost(IHostBuilder hostBuilder) => hostBuilder
.ConfigureHostConfiguration(builder => { })
.ConfigureAppConfiguration((context, builder) => { });
}
[MemberData] how to inject?
Use [MethodData]
Integrate OpenTelemetry
TracerProviderBuilder builder;
builder.AddSource("Xunit.DependencyInjection");
Do something before and after test case
Inherit BeforeAfterTest
and register as BeforeAfterTest
service.
Initialize some data on startup.
If it is synchronous initialization, you can use the Configure
method. If it is asynchronous initialization, you should use IHostedService
.
