jasmine unit testing - testing for an undefined property of an object
提问by wmitchell
I have the following statement
我有以下声明
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.
由于我的对象 A 具有顶级属性“BAR”，而 bar 具有值“foo”传递。
I'd like to test my structure to confirm a property "NONEXISTINGPROP" has not be defined. e.g.
我想测试我的结构以确认尚未定义属性“NONEXISTINGPROP”。例如
expect(A.["NONEXISTINGPROP"].name).not.toBeDefined();
However I seem to get
但是我似乎得到
"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.
在茉莉花测试运行器中，这正是我想要确认的。知道茉莉为什么哭了。我希望它能通过这个。
Thanks SO
