Test Automation Strategies in Lightning due to dynamic locators

I'm working on Selenium Test Automation of my App using the LEX.  In Classic, locators are static in that I can reference an ID number or name, whereas it seems the same field/object in LEX has dynamic IDs depending on when I access said element.

HTML from LEX yields:
<a aria-required="true" class="select" aria-disabled="false" aria-haspopup="true" tabindex="0" role="button" aria-label="Enrollment Type" title="" href="javascript:void(0);" data-aura-rendered-by="2944:0" data-interactive-lib-uid="60">--None--</a>

I try to use the bold faced section as a locator, but it changes each time I click on it.  Here's another example of the same elment. As you can see the id is now 90, instead of 60 above.
<a aria-required="true" class="select" aria-disabled="false" aria-haspopup="true" tabindex="0" role="button" aria-label="Enrollment Type" title="" href="javascript:void(0);" data-aura-rendered-by="4995:0" data-interactive-lib-uid="90">--None--</a>

Here's a snippet from classic, where I can always US the same ID.  It never changes.  Has anyone found a solution to this problem for finding element locators in LEX?
<select id="00No000000DyWd7" name="00No000000DyWd7" tabindex="8"><option value="">--None--</option><option value="New Enrollment">New Enrollment</option><option value="Re-Enrollmet">Re-Enrollmet</option><option value="Re-Validation">Re-Validation</option><option value="Information Update">Information Update</option></select>

I'm making progress on this, although it's been a ton of trial and error since it's very difficult to find a unique locator to get to the element that I want.  The general approach I am taking is to find labels or text that are generally static throughout my app.  I reference them and then use the 'following' syntax for xpath in order to find the element that I am looking at.  I used a lot of Ctrl-F in the html inspector to look for uniqueness.

For instance, I have a custom object called 'Credentialing'.  The word 'Credentialing' is used a lot throughout my app, so it's hard to key in on this.  What I was looking to do was locate a lookup field called 'Credentialing Manager', which looks up to Salesforce Users.  I used the below locators to Edit the desired field, type values to search for users, and select the users.
1. Edit the Desired field: xpath="//button[@title='Edit Credential Manager']". This found a button on screen with the referenced title.
2. Type in the clicked on field: xpath="//input[@placeholder='Search People']"
3. Select name from list that was displayed based on #2: xpath="input[@placeholder='Search People']//following::li[3]"  This finds the field placeholder "Search People" and then navigated to the third li tag that folows it.  

A less brittle way of finding #3 above is to use the following xpath because it's not relying on the 3rd li tag, but looking for specific text you're searching for.  For instance I was searching for my name, Jacob Friedman, in #2 above.  This way, I can use the same locator across many orgs and get consistent results.  If I use the li locator, the location of value that I am looking for could vary in every single org, thus making my test less versatile.

xpath="//div[@title='Jacob Friedman']"

Hi Jacob - I am having a similar issue with the drop down element, which I am not able to select the drop down. And I am not able to find anything unique with this element. Do you remember what worked for you?

Please find my element below,

<a aria-required="false" class="select" aria-disabled="false" aria-describedby="1838:2908;a-label" aria-haspopup="true" tabindex="0" role="button" title="" href="javascript:void(0);" data-aura-rendered-by="1848:2908;a" data-interactive-lib-uid="75">--None--</a>

Hi. Here’s an example of what I did: This is the element that I want to click on. @FindBy(xpath=".//*[@title='Pre-Contract']") WebElement selectStageLEX; This is the value I’d like to click on in the picklist @FindBy(xpath=".//*[@class='scrollable']//*[@title='Authoring']") WebElement selectStageAuthLEX; I often had to try and find a unique class in the xpath and then traverse up to parent and then down to siblings. Like this: @FindBy(xpath=".//*[@class='test-id__field-label-container']/*[.='Stage']/parent::*/following-sibling::div/span/span") WebElement contractStageRdLEX;

Hi. I ended up having to use some complicated xpath locations to get this to work. It’s been over a year since I worked in SalesForce, but below are some examples. I think these are finding titles of a button, then going to the parent above it down to another level. xpath=".//*[@title='Edit XYZ Status']/parent::*/span/span" xpath="//button[@title='Edit XYZ Process Start Date']/preceding::span[2]" I think this one goes to the title of the button, goes to the preceding node, then goes to the second span. Give it a shot…
