Log the thrown exception

I'm looking for a way to include the error message when the thrown exception is expected.

Here's my test:

describe('Process Text', function(){
  _.each(shouldThrow, function(option){
    it('throw error ('+option+')', function(){
      expect(function(){
        main.textValidation(option)
      }).to.throw()
    })
  })
  _.each(shouldNotThrow, function(option){
    it('not throw error ('+option+')', function(){
      expect(function(){
        main.textValidation(option)
      }).to.not.throw()
    })
  })
})

Here's the logged message from mocha:

✓ throw error (notify --message "Hello world" --open "https://www.holstee.com" --queue 15-04-30-16) 
✓ throw error (--notify --message "Hello world" --open "https://www.holstee.com") 
✓ throw error (--notify --message "Hello world" --open "https://www.holstee.com --queue "2015-04-30-16-10) 
✓ not throw error (notify --message 'Hello world' --open 'https://www.holstee.com') 
✓ not throw error (notify --message "Hello world" --open "https://www.holstee.com --queue 2015-04-30-16-10) 

The desired output is something like this

✓ throw error 
  * option: notify --message "Hello world" --open "https://www.holstee.com" --queue 15-04-30-16
  * error: invalid flag value `queue` should be 16 characters long
✓ throw error
  * option: --notify --message "Hello world" --open "https://www.holstee.com"
  * error: invalid parsed argument(s): notify
✓ throw error
  * option: --notify --message "Hello world" --open "https://www.holstee.com --queue "2015-04-30-16-10
  * error: invalid unparsed argument(s): 2015-04-30-16-22
✓ not throw error 
  * notify --message 'Hello world' --open 'https://www.holstee.com'
✓ not throw error 
  * notify --message "Hello world" --open "https://www.holstee.com --queue 2015-04-30-16-10

I tried this, did not work

  describe('Process Text', function(){

    beforeEach(function () {
      test_name = this.currentTest.title;
    });

    _.each(shouldThrow, function(option){
      it('throw error', function(){
        test_name += "\n"
        test_name += "* option:"
        test_name += option
        expect(function(){
          try{
            main.textValidation(option)
          }catch(e){
            test_name += "\n"
            test_name += "* message:"
            test_name += e.message
            throw(e)
          }
        }).to.throw()
      })
    })
    _.each(shouldNotThrow, function(option){
      it('not throw error', function(){
        test_name += "\n"
        test_name += "* option:"
        test_name += option
        expect(function(){
          main.textValidation(option)
        }).to.not.throw()
      })
    })
  })
