selenium - Ignore all tests from specflow using [BeforeTestRun] hook -

my project has 2 default configurations (debug , release) , custom 1 called uitest.

when uitest config selected changes ioc use in memory verson of database perfect ui tests.

i using nunit , resharper run tests , run ui tests when uitest configuration active.

i decided go [beforetestrun] hook achieve cant ignore tests.

throwing exception prevent tests running show fail, prefer have them show pending or ignored. possible?

    [beforetestrun]     public static void beforetests()     {     #if !uitest         throw new exception("abort!");     #endif     } 

addendum

if change this:

    [beforetestrun]     public static void beforetests()     {     #if !uitest         assert.ignore();     #endif     } 

then each of scenarios show ignored feature fail.

the beforetestrun hook method runs once, before run starts. if want skip whole testrun, can use environment.exit(); exit run.
in mstest tests show not run, not sure how nunit or resharper handles this.
