The method getApiResult() does not exist on Symfony\Component\Mailer\Transport\AbstractTransport. It seems like you code against a sub-type of Symfony\Component\Mailer\Transport\AbstractTransport such as LeKoala\Mandrill\MandrillApiTransport.

        $firstMail = $result[0] ?? [];

        $this->assertEquals($test_to, $firstMail['email']);
        $this->assertEquals("sent", $firstMail['status']);
