It seems like new CoiSA\Http\Middleware\RequestHandlerMiddleware($this->requestHandler->reveal()) of type CoiSA\Http\Middleware\RequestHandlerMiddleware is incompatible with the declared type CoiSA\Http\Middleware\EchoBodyMiddleware of property $middleware.

        $testClass = $this;
        $callback  = function () use ($testClass) {
            $testClass->execution[] = \spl_object_hash($this);

            return $testClass->response->reveal();
        };

        $this->requestHandler->handle($this->serverRequest->reveal())->will($callback);
        $this->next->handle($this->serverRequest->reveal())->will($callback);
    }

The method handle() does not exist on CoiSA\Http\Middleware\EchoBodyMiddleware.

        $requestHandler = $this->requestHandler->reveal();
        $this->assertEquals($requestHandler->handle($serverRequest), $response);
