Ever since I received the BDD test naming macro from Scott Bellware last year, it has gone through several iterations of improvements (mostly due to students taking the time to tune up the macro).

Of all of the enhancements to the macro, none of them have done as much for the speed of the macro of the enhancements made by:

Todd Berry and Casey Gum

The macro now runs so fast that it is a joy to watch (you have to be quick). For those of you who are switching to leveraging context style BDD testing, you may want to pick up the macro and integrate it into your IDE:

Imports System

Imports System.Windows.Forms
Imports EnvDTE
Imports EnvDTE80
Imports System.Diagnostics

Public Module CodeEditor

    Public Sub ReplaceSpacesInTestNameWithUnderscores()
        If DTE.ActiveDocument Is Nothing Then Return
        Dim wrCS As Boolean = DTE.Properties("TextEditor", "CSharp").Item("WordWrap").Value

        Try
            DTE.Properties("TextEditor", "CSharp").Item("WordWrap").Value = False
            Dim selection As TextSelection = CType(DTE.ActiveDocument.Selection(), EnvDTE.TextSelection)
            Dim index As Integer

            selection.SelectLine()
            If selection.Text = "" Then Return

            Dim methodIndex As Integer = selection.Text.IndexOf("public void ")
            Dim classIndex As Integer = selection.Text.IndexOf("public class ")

            If (methodIndex < 0 AndAlso classIndex < 0) Then Return

            index = CType(IIf(methodIndex >= 0, methodIndex, classIndex), Integer)

            Dim prefix As String = CType(IIf(methodIndex >= 0, "public void ", "public class "), String)
            Dim whiteSpace As String = selection.Text.Substring(0, index)
            prefix = whiteSpace + prefix
            Dim description As String = selection.Text.Replace(prefix, String.Empty).Trim
            Dim text As String = prefix + description.Replace(" ", "_").Replace("'", "_") + vbCrLf
            selection.Delete()
            selection.Insert(text)
            selection.LineUp()
            selection.LineUp()
            selection.SelectLine()
            If selection.Text.Trim = "{" Or selection.Text.Trim = "}" Or selection.Text.Trim = "" Then
                If selection.Text.Trim = "{" Or selection.Text.Trim = "}" Then
                    selection.Insert(selection.Text.Replace(vbCrLf, "") + vbCrLf)
                ElseIf selection.Text.Trim = "" Then
                    selection.Delete()
                End If
                selection.Insert(whiteSpace + IIf(methodIndex >= 0, "[Test]", "[TestFixture]") + vbCrLf)
            End If
            selection.LineDown()
            selection.LineDown()
            selection.EndOfLine()
        Catch ex As Exception
            MsgBox(ex.Message)
        Finally
            DTE.Properties("TextEditor", "CSharp").Item("WordWrap").Value = wrCS
        End Try
    End Sub
End Module
