        $request->expects(self::any())->method('getParsedBody')->willReturn($body);

        self::assertSame($expectedExtractedValue, (new ExtractCSRFParameter($requestParameter))->__invoke($request));

It seems like $request defined by $this->createMock(\Psr\Http\Message\ServerRequestInterface::class) on line 36 can also be of type object<PHPUnit_Framework_MockObject_MockObject>; however, PSR7Csrf\RequestParameter\ExtractCSRFParameter::__invoke() does only seem to accept object<Psr\Http\Message\ServerRequestInterface>, maybe add an additional type check?
