Resolving Logout Button Selection Issue in Nightwatch.js Tests for Different User Roles

In a web application, the user avatar dropdown shows three options (Profile, Setting, Logout) for administrators, but only two options (Profile, Logout) for regular users. Existing Nightwatch.js tests clicked the third list item to trigger logout, which fails for regular users because the element does not exist.

One approach is to add conditional logic to detect the user role and click the appropriate list item, but this adds complexity. A simpler solution is to target the logout button directly by its Angular click handler, which is consistent across both user types.

Inspecting the page with the browser's developer tools reveals that the logout link always contains the attribute ng-click="logout()" . Selecting the element using this attribute works regardless of its position in the menu.

The test code is updated as follows:

// logout: 'ul.dropdown-menu-user:not(.status-dropdown-menu) > li:nth-child(3) > a'

logout: '[ng-click="logout()"]'

This change ensures the Nightwatch.js script reliably clicks the logout button for both admin and regular users without additional role‑checking logic.
