this.restApi.root.addResource("test").addMethod("GET", new MockIntegration({
        requestTemplates: {
            'application/json': `{"statusCode" : 200}`
        },
        integrationResponses: [
            {
                statusCode: '200',
                responseTemplates: { 'application/json': `{"name": "John"}` }
            }
        ]
    }), {
        methodResponses: [
            {
                statusCode: '200',
                responseModels: { 'application/json': Model.EMPTY_MODEL }
