Finally, to fix those broken tests make the setUp() method look like this to skip the tests when using the TokenAnalyser:

    public function setUp(): void
    {
        parent::setUp();
        
        if ($this->getAnalyzer() instanceof TokenAnalyser) {
            $this->markTestSkipped();
        }
    }
