Test runner

var a = window.document;

var a = window["document"];

var a = foo.path.to.node.value;

var a = bar['path.to.node.value'];

var a = baz['this.is.long.path.name.foo.bar.baz.path.to.node.value'];

var a = qux['value'];

var a = foo['path']['to']['node']['value'];

var a = ( foo['path'] && foo['path']['to'] && foo['path']['to']['node'] && foo['path']['to']['node']['value'] );

var a = (((((foo||0).path||0).to||0).node||0).value );
