SpecFlow equivalent to parameterized test fixture

Question

I’m using SpecFlow to write a set of tests, and I’d like to run each test multiple times, with different input data. I could do this with scenario outlines, but I want to run every scenario in the feature file with the same test cases.

I know I can use the Background to share the setup for one case, but I’m looking for something like a cross between Background and Scenario Outline, where I can supply a table of data to the Background and run the entire feature file once per row.

In NUnit, I’d use a parameterized test fixture to achieve this. Is there any equivalent in SpecFlow?

You can utilize specflow assist helpers to create data table object and use it in Background

Background:
    Given I’ve Entered The Following Information
    | FirstName| LastName|Email      |
    | Abcd1    | Xyz1    |[email protected]|
    | Abcd2   | Xyz2     |[email protected]|

class Person
{
string FirstName { get; set; }
string LastName { get; set; }
string email { get; set; }
}

Usage:

    [Binding]
  [Given(@"I’ve Entered The Following Information")]
    public void UseData(TechTalk.SpecFlow.Table table)
    {
        var enumeratePersons = table.CreateSet<Person>();   
          foreach (Person P in enumeratePersons ){

             log.Info(P.FirstName + " " + P.LastName );
          }
     }

You might have to use properties or specflow context to share data between bindings. When Background is run , it will create the data object for each scenario but to use it across bindings is user's responsibility
