c# - How do I assert that an Observable doesn't push any item? -


i know how unit test sequences observable.never.

how can sure nothing pushed sequence?

you cannot sure nothing ever pushed observable, because equivalent solving halting problem, impossible. is: want know if program ever terminate (something pushed) or run forever (nothing ever pushed).

the best can check if nothing pushed during arbitrary timeout of choice.

that said - don't need test observable.never anyway. if have real code observable should never push items - please show in question.

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
