Shared Methods Between Selenium And SpecFlow

I have a test project that holds all the Selenium scenarios that I want to test and I want to add a SpecFlow project to this solution that obviously will use some of the WebDriver methods. I don't want to duplicate my code but the SpecFlow is not working well with the Selenium (for example Selenium is using the [TestInitialize] attribute which is not allowed in SpecFlow). What is the best way to combine the two?

I want to do the same steps as in "SomeTestMethod" but with SpecFlow.

This is an example of the project:

public class SeleniumBaseTest : BaseTest
{
    [AssemblyInitialize]
    public static void Initialize(TestContext testContext)
    {
    }

    Public SomeMethod()
    {
    }
}
[TestClass]
public class SeleniumFeature : SeleniumBaseTest 
{
   [TestInitialize]
   public void SeleInitialize()
   {
   }

   [TestMethod]
   public void SomeTestMethod()
    {            
    }
}

You can use attributes aka hooks like:

[BeforeTestRun] [AfterTestRun]

[BeforeFeature] [AfterFeature]

[BeforeScenario] or [Before] [AfterScenario] or [After]

[BeforeScenarioBlock] [AfterScenarioBlock]

[BeforeStep] [AfterStep]

Since SpecFlow steps are really just public methods on a class that inherits from System.Object, just instantiate the step definition class and call the public methods from your Selenium test.

DataSteps.cs

[Binding]
public class DataSteps
{
    [Given("Something exists in the database")]
    public void GivenSomethingExistsInTheDatabase()
    {
        // ...
    }
}

In your Selenium test class:

[TestClass]
public class SeleniumFeature : SeleniumBaseTest 
{
    private DataSteps dataSteps;

    [TestInitialize]
    public void SeleInitialize()
    {
        dataSteps = new DataSteps();
    }

    [TestMethod]
    public void SomeTestMethod()
    {
        dataSteps.GivenSomethingExistsInTheDatabase();
    }
}

The only real pain is when you need to use a TechTalk.SpecFlow.Table object as a parameter to a step definition. To figure out that syntax look at the Designer-generated source for one of the .feature files that uses the Gherkin table syntax, e.g.

Scenario: Testing something important
    Given a Foo exists with the following attributes:
        | Field | Name  |
        | Name  | Foo   |
        | Fruit | Apple |

If it helps, you can keep the step definitions in their own assembly.
