My SpecFlow steps are not restricted by namespace

If your using SpecFlow you have probably realised that SpecFlow steps definitions are not restricted by namespace. This means it can be challenging to write steps that are generic but won’t conflict with other steps. For a while i thought this was just a limitation to SpecFlow. It turns out i didn’t know about the Scoped Step Binding feature of SpecFlow. This allows you to restrict a step definition by Feature, Scenario or Tag and seems to be a little known feature.  As the SpecFlow wiki guide suggests this can also be used to ignore something with an @manual tag by supplying it with empty methods.

Here’s an example from the SpecFlow wiki

[When(@"I perform a simple search on '(.*)'", StepScope(Tag = "controller"))]
public void WhenIPerformASimpleSearchOn(string searchTerm)
    var controller = new CatalogController();
    actionResult = controller.Search(searchTerm);

[When(@"I perform a simple search on '(.*)'"), StepScope(Tag = "web")]
public void PerformSimpleSearch(string title)
    selenium.Type("searchTerm", title);

    Thanks, this is exactly what I was looking for! As of SpecFlow 1.8 scope is its own attribute:

    [Given(“I have entered (\d+) into the calculator”), Scope(Tag = “calculator”)]
