help w/testing: variables not passed to view in 4.5.4

Hi,
I'm using 4.5.4 and I'm trying to set up some tests but I'm having a difficult time. This is the code from my controller:

Code:

    $data['is_new'] = $is_new;
    return view('my_body', $data);

Then in the view I have this:

PHP Code:

<?php

?>
  if ($is_new) {
    <?php
      print "Welcome, new user.";
    ?>
  } else {
      print "Welcome back.";
  } 


In my test, which I pretty much copied from the docs:

PHP Code:

<?php
  namespace app\Controllers;
  use CodeIgniter\Test\CIUnitTestCase;
  use CodeIgniter\Test\FeatureTestTrait;
  use CodeIgniter\Test\DatabaseTestTrait;
  use PHPUnit\Framework\Attributes\TestDox;

  class MyControllerFeaturesTest extends CIUnitTestCase
  {
    use FeatureTestTrait;
    use DatabaseTestTrait;
    /**
    * setup and teardown run before and after
    * the _entire_ test case
    * setup and tearDown run _between_ tests
    */
    public static function setUpBeforeClass(): void
    {
      parent::setUpBeforeClass();
    }
    public static function tearDownAfterClass(): void
    {
      parent::tearDownAfterClass();
    }
    protected function setUp(): void
    {
      parent::setUp(); // Do not forget

      helper('text');
    }
    protected function tearDown(): void {
      parent::tearDown();
    }

    #[TestDox('A new user should get a welcome')]
    public function testViewingResults(): void
    {
      $response = $this->get('/forum/loggedin/79435')
                        ->call();
      $response->assertSee('Welcome, new user');
    }
  } 


The error I'm getting is that $is_new is not defined in the view:

Code:

ErrorException: Undefined variable $is_new

The page actually works just fine, no errors at all. I can go to the url, see the appropriate message based on whether or not I'm a new user. 

Any ideas?

All ok.

Code:

OK (1 test, 1 assertion)

    public function index(): string
    {
        $is_new        = true;
        $data['is_new'] = $is_new;
        return view('welcome_message', $data);
    }
}
// app/Views/welcome_message.php
<?php
    if ($is_new) {
        print "Welcome, new user.";
    } else {
        print "Welcome back.";
    }
?>

        $response = $this->get('/');
        $response->assertSee('Welcome, new user');
    }

All ok.

Hmm. So something I either missed or didn't get in the code when I was stripping out the junk.
