Description: 

Drupal\Tests\BrowserTestBase::drupalGetHeader() is deprecated. Use $this->getSession()->getResponseHeader() instead.

When testing for the value of a header, consider using responseHeaderEquals() instead:

Before:
$this->assertSame('HIT', $this->drupalGetHeader('X-Drupal-Dynamic-Cache'));

After:
$this->assertSession()->responseHeaderEquals('X-Drupal-Dynamic-Cache', 'HIT');
