I just started with Saleforce/Force.com development. I set up a couple of Selenium tests last week, but they crashed today, since Salesforce upgraded to Version Winter '14 on my Dev Sandbox. My Selenium tests rely on the id-tags within the DOM, which now have other numbers.

I would like to know on which DOM elements you guys rely on to run Selenium tests?

Are you using Selenium IDE or Selenium Webdriver?

I'm using the latter and match Salesforce Ids using css selectors - if your visualforce is annotated with Ids then your id will always appear at the end of the salesforce generated Id. For example:

A visualforce entry like this:

<apex:inputField id="accountName" value="{!CustomObjectX__c.Account__c}" required="true">

Will be rendered as this mess:

<input id="j_id0:j_id1:TheForm:j_id77:j_id78:j_id79:accountName" maxlength="255" name="j_id0:j_id1:TheForm:j_id77:j_id78:j_id79:accountName" onchange="A4J.AJAX.Submit('j_id0:j_id1:TheForm',event,{'similarityGroupingId':'j_id0:j_id1:TheForm:j_id77:j_id78:j_id79:accountName:j_id82','parameters':{'j_id0:j_id1:TheForm:j_id77:j_id78:j_id79:accountName:j_id82':'j_id0:j_id1:TheForm:j_id77:j_id78:j_id79:accountName:j_id82'} ,'containerId':'j_id0:j_id1:TheForm:j_id77:j_id78:j_id79:j_id81'} )" size="20" type="text" value="The Account Name">

meaning you can reference the component using the following css selector:

"input[id$='accountName']"

(An input that has an id which ends with accountName - signified by the $=)

This will then match in any org your code is deployed to. Using selectors gives you more flexibility too, you can match on other attributes of the rendered html. Take a look at CSS selectors for Selenium which gives a good starting overview and also covers how to use such selectors if you are using Selenium IDE

I would stay away from using ID tags for automated testing, if you are testing a VF page you can use the class name instead.

  • What would you recommend then for a test using/requiring standard pages? Button or link values (such as "Edit" or "Save") or something else? – Mike Chale Sep 9 '13 at 12:39
  • I was thinking about using class names as unique identifiers, but I do not have access to it - yet. For now I use XPath Queries and I hope that the DOM wont change. – Mathias Maciossek Sep 9 '13 at 13:42
