Class Attribute

Class attribute of an element may contain more than one class reference. E.g.

<button class="btn btn-primary btn-test">

XPath selector relying on a class must be well formed. For example, the following will not work:

//button[@class='btn-primary']

Correct variant is

//button[contains(concat(' ', normalize-space(@class), ' '), ' btn-primary ')]

Scenario

• Record primary (blue) button click and press ok in alert popup.
• Then execute your test to make sure that it can identify the button using btn-primary class.
