65341 ajax actions widgets order

[pbearne]

This PR adds unit tests for the wp_ajax_widgets_order() function located in src/wp-admin/includes/ajax-actions.php.
And checks for $_POST[sidebars]? for use

The tests cover:

• Successful saving of the widgets order for multiple sidebars.
• Proper handling of invalid nonces (save-sidebar-widgets nonce).
• Verification of user permissions (edit_theme_options capability).
• Behavior when the sidebars parameter is missing.

Is this the correct @since version?

[mindctrl]

I don't think these assertions run because they come after phpunit catches the exception thrown by _handleAjax(). If you disable these, you'll see the assertion count remains the same. Same for line 62 I think.

I'm not sure if this is the best/proper approach, but if you do the test like this, it will run the other assertions:

		try {
			$this->_handleAjax( 'widgets-order' );
			$this->fail( 'Expected WPAjaxDieStopException was not thrown.' );
		} catch ( WPAjaxDieStopException $e ) {
			$this->assertSame( '1', $e->getMessage() );
		}

I think the classname, or filename, needs to be changed? If running these tests in isolation, by referencing the filename, you get an error about being unable to find class widgetsOrder.
