You can't delete a local variable that has been declared with var.
You can only delete properties of objects - this happens to also include global variables which are implicit properties of the window object.

As has been mentioned, you can't delete a variable that has been declared with var.
For example, if you were to change your code to the following - so that test is an explicit property of window - the delete will work.
window.test = [];
window.test[0]="111";
window.test[1]="555";
delete window.test;
alert(window.test[0]);

You can delete properties on objects, you can't delete variables.
Either assign undefined or let the variable fall out of scope.

Whenever delete, it returns a boolean that tells wether it could delete the var or not. In this case, it returns false:
delete test; // false
You can just set test to undefined:
test = undefined;
Comments
you can use test = undefined to make remove object value
