OK. I'll change it to 'node'.

OK. I'll change it as you recommended.

In order to display useful information,
I have to send the second parameter of 'shouldbe' as a constant, not a variable.
It means I can't use function. I have to just spread out them like 'textarea-maxlength.js'.
If I have to do like that, I'll do it.
> Why don't you just pass element to startTest & testHandler instead of making if statement like this.
Because 'eval' in 'shouldBe' throws exception like 'ReferenceError: element is not defined.' if I use local variable or just argument, I put global variable and assign node to it.
As I told above,
If I change it to spread out, not using function,
This code will be removed.

Yes, I'll check it in test case as well.

It's same as the above.
The 'eval' in 'shouldBe' throws exception if I use local variable or just argument.
I have to use constant at 'shouldBe' in order to show more useful information.
So, I'll change this test to spread out sentences like 'textarea-maxlength.js'.
Do you approve of my idea?
