SpecFlow.Autofac

SpecFlow plugin for using Autofac as a dependency injection framework for step definitions.

Currently supports

  • SpecFlow v2.1
  • Autofac v3.5.2 or above

License: Apache (https://github.com/gasparnagy/SpecFlow.Autofac/blob/master/LICENSE)

NuGet: https://www.nuget.org/packages/SpecFlow.Autofac

See my blog post (http://gasparnagy.com/2016/08/specflow-tips-customizing-dependency-injection-with-autofac/) for more information and background, you can also look at the complete example at https://github.com/gasparnagy/SpecFlow.Autofac/tree/master/sample/MyCalculator.

Build status

Usage

Install plugin from NuGet into your SpecFlow project.

PM> Install-Package SpecFlow.Autofac

Create a static method somewhere in the SpecFlow project (recommended to put it into the Support folder) that returns an Autofac ContainerBuilder and tag it with the [ScenarioDependencies] attribute. Configure your dependencies for the scenario execution within the method. You also have to register the step definition classes, that you can do by either registering all public types from the SpecFlow project:

builder.RegisterAssemblyTypes(typeof(YourClassInTheSpecFlowProject).Assembly).SingleInstance();

or by registering all classes marked with the [Binding] attribute:

builder.RegisterTypes(typeof(TestDependencies).Assembly.GetTypes().Where(t => Attribute.IsDefined(t, typeof(BindingAttribute))).ToArray()).SingleInstance();

A typical dependency builder method probably looks like this:

[ScenarioDependencies]
public static ContainerBuilder CreateContainerBuilder()
{
  // create container with the runtime dependencies
  var builder = Dependencies.CreateContainerBuilder();

  //TODO: add customizations, stubs required for testing

  builder.RegisterTypes(typeof(TestDependencies).Assembly.GetTypes().Where(t => Attribute.IsDefined(t, typeof(BindingAttribute))).ToArray()).SingleInstance();
  
  return builder;
}
