问使用phpunit测试路由通配符？

EN

    /**
     * @Route("api/1.0/test/{$a}", name="test", methods={"GET"})
     * @return JsonResponse
     */
    public function testSimple(int $a)
    {
        return $this->json(['success' => ($a == 1) ? true : false]);
    }

    /**
     * @test
     */
    public function checkRouteWildcardReturnsExepctedResult()
    {

        $client = $this->createClient();
        $request = $client->request('GET','api/1.0/test/1');

        $response = $client->getResponse()->getContent();
        $this->assertEquals(json_encode(["success" => true]), $response);

    }
