Reuse background definition between two feature files in Specflow

Question

I have several specflow .feature files to test different entities of a web api project.

For every entity I have to create a background with all the needed data in my database, but before of all I need to delete all data, and need to delete using web api calls (not by sql query). I'm doing this:

Background: 
Given I make a new request to localhost on port 53364 
    And the path is api/voipport/deleteAll 
    And the request type is Delete
    When the request has completed
Given I make a new request to localhost on port 53364 
    And the path is api/loopblockingexception/deleteAll 
    And the request type is Delete
    When the request has completed
Given I make a new request to localhost on port 53364 
    And the path is api/stimulationcode/deleteAll 
    And the request type is Delete
    When the request has completed
Given I make a new request to localhost on port 53364 
    And the path is api/switch/deleteAllMtp3
    And the request type is Delete
    When the request has completed
Given I make a new request to localhost on port 53364 
    And the path is api/enviroment/deleteAll 
    And the request type is Delete
    When the request has completed

Given it has the following topologies
    | Id | Name  | Description  |
    | 1  | Test  | Description  |
    | 2  | Test2 | Descritpion2 |
Given it has the following eas

Given it has the following mtp3Switchs

It works perfect, but I have several .feature files that need to execute the same deleteAll methods. Can I write any kind of method with all the Given/When instructions in other .feature file (or another kind of file) and call this method from every background code?

Answer 1

Dont forget that your [Binding]s are global. In theory you could have one binding file with all your Given \ When \ Thens in it.

Also, why don't you send your WebService a single reset command, rather than building them up in this manner? You could enable a new command such as api/testing/deleteAll which is only availble if you run your webService with a special config value.
