I have the following statement

expect(A.[BAR].name).toEqual(foo); 

which due to the fact my object A has the top level property BAR and bar has the value foo passes.

I'd like to test my structure to confirm a property NONEXISTINGPROP has not be defined.
e.g.

expect(A.[NONEXISTINGPROP].name).not.toBeDefined(); 

However I seem to get

  TypeError: A.[NONEXISTINGPROP] is undefined 

in the jasmine test runner this is exactly what I want to confirm. Any idea why Jasmine is crying. I was hoping for it to pass this.

Thanks SO
