Is there a specific attribute called parentElementArrayFinder within an ElementFinder object that can retrieve the parent element?
var myElement = $(".myclass");
var parentElement = myElement.parentElementArrayFinder;
Although not listed in Protractor's public API, is parentElementArrayFinder a dependable and consistent method for identifying a parent element, ensuring it returns the same element as
myElement.element(by.xpath(".."))The code snippet for the ElementFinder can be located here, where it contains a reference to parentElementArrayFinder which is defined here.
Upon inspecting the code, it becomes evident that an error will be thrown if parentElementArrayFinder is not present.
super();
if (!elementArrayFinder) {
throw new Error('BUG: elementArrayFinder cannot be empty');
}
this.parentElementArrayFinder = elementArrayFinder;
Given this information, we can reasonably infer that the parentElementArrayFinder will always be available and can be used without concern.
In summarizing the feedback, the existing response, my personal observations, and reviewing the source code, it is clear that the parentElementArrayFinder function should only be utilized when the element obtained for parentElementArrayFinder was "chained" from another element.
An example of how to correctly use this function is shown below:
var parent = element(by.css(".parent"));
var child = parent.element(by.css(".child"));
child.parentElementArrayFinder # linked to "parent" - valid usage
On the other hand, incorrect usage would look like this:
var child = element(by.css(".child"));
child.parentElementArrayFinder # no link to "parent" - invalid usage
