Add external tool in Visual Studio to automatically launch NUnit on the current file

visual studio 2012 nunit integration

== LAUNCH NUnit FROM VS2012 ===========================================

TOOLS -> External Tool -> Add

    Title: NUnit
    Command: C:\path\to\nunit.exe
    Arguments: $(TargetName)$(TargetExt)
    Initial Directory: $(ProjectDir)\bin\Debug

TOOLS -> External Tool -> Add

    Title: NUnit-console
    Command: C:\path\to\nunit-console.exe
    Arguments: $(TargetName)$(TargetExt) /wait  /xml=nunit-test-result.xml /labels
    Initial Directory: $(ProjectDir)\bin\Debug

    /wait will stop before closing the console (to analyze output) otherwise use: /out=nunit-test-out.log
    /xml  will create a result report (usefull for graph geneation)
    /labels will label tests in stdout

From now on, you will have two new external tools under TOOLS named NUnit and NUnit-console.
If you click on them, NUnit or Nunit-console will be launched and the current assembly will automatically be loaded.
NUnit (gui) automatically reload assembly when dll is re-built


== EXTERNAL TOOL IN TOOLBAR ============================================


VIEW -> Toolbars -> Customize

    Toolbs TAB -> New Toolbar -> Name: "Nunit"
    Commands TAB -> Select Toolbar choice -> select "NUnit" toolbar from drop down
                 -> Add Command -> Category: "Tools" + Commands: "External Command X" (choose the right one)

Now you have the ability to launch it directly from toolbar.
