How to select elements with same ID but in different shadow DOMs - cypress

Question

So I'm working at a co. as a summer intern and have been tasked with writing tests for their application in cypress.
The application extensively uses shadow DOMs and nested shadow DOMs even. I used the includeShadowDom property true to traverse more easily. But I am facing an issue.
I need to type in 2 input boxes having the same ID and same class but they are in separate shadows. Is there a way I can distinguish between them i.e First occurrence of element with id= and nth occurrence of element with id=?
I can't share any code because it goes against company policy

Answer 1

Assuming you have added includeShadowDom: true in your cypress config file then you can use the eq method to get the respective elements.
E.g. eq(0) for first occurrence of the element, eq(1) for the second and so on.
So your code should look like this:
cy.get('input').eq(0).type('some text')

Answer 2

First possible solution is to select every input with class = something and loop over each.
let words = ['First input', 'second input']
cy.get(`input[class="something"]) // this returns x number of Inputs
.each( ($el, index) => {
cy.get($el)
.type(words[index])
})
Second possible solution is to target the parent element incasing the single input.
cy.get('table') //I don't know what is incasing your inputs but lets assume its a table
.within( () => {
cy.get(`input[class="something"`] //trying to get this to return 1 element
.type('words')
})
Without seeing your HTML markup I can't offer up a more exact solutions. Hope this helps. Look up parent() and parentsUntil() cypress commands if you try the second option.

Answer 3

With inputs there's usually some text that allows the user to distinguish them.
Try targeting the input label or placeholder text, finding the input with "Traversal" commands.
<div>
<label>User name</label>
<input type="text" placeholder="Enter user name" />
<div>
Some basic approaches:
cy.contains('label', 'User name')
.next() // move to next element in the DOM
.type('something')
cy.contains('div', 'User name') // go to common parent of label and input
.find('input') // gives just the input inside parent
.type('something')
cy.get('input[placeholder="Enter user name"]') // use unique placeholder attribute
.type('something')
With shadow DOM be aware you can configure it in the test header
it('searches inside all shadow dom roots', {includeShadowDom: true}, () => {
...
})
