NSpec integration tests for MSSQL and MySQL

Hi, I've prototyped nspec style integration tests for the project.
The tests cover basic scenarios of sequential runs of roundhouse on 2 databases.

Please let me know what do you think.

Here is an example of the spec: 

    describe roundhouse spec
      when mssql
        rh executed with v2 scripts
          should create table timmy
          should create table SampleItems
          get assert database one time scripts run should be Convert 3
        have v1 database
          should create table timmy
          should not create table SampleItems
          get assert database one time scripts run should be Convert 1
          rh executed v2 in dry run mode
            should not create table SampleItems
            get assert database one time scripts run should be Convert 1
            rh executed v2 in normal mode
              should create table SampleItems
              get assert database one time scripts run should be Convert 3
          rh executed v2 in baseline mode
            should not create table SampleItems
            get assert database one time scripts run should be Convert 3
            rh executed v2 in normal mode
              should not create table SampleItems
              get assert database one time scripts run should be Convert 3
          rh executed v2 in normal mode
            should create table SampleItems
            get assert database one time scripts run should be Convert 3
      when mysql
        rh executed with v2 scripts
          should create table timmy
          should create table SampleItems

        have v1 database
          should create table timmy
          should not create table SampleItems
          get assert database one time scripts run should be Convert 1
          rh executed v2 in dry run mode

              get assert database one time scripts run should be Convert 3
          rh executed v2 in baseline mode
            should not create table SampleItems
            get assert database one time scripts run should be Convert 3
            rh executed v2 in normal mode
              should not create table SampleItems
              get assert database one time scripts run should be Convert 3
