Mushrooms

Mushrooms is an easy setup mock or stub framework. To ensure high levels of efficiency for remote service integration.

Why

Remote service integration, especially based on HTTP protocol, e.g. web service, REST etc, highly unstable when developing.

Features

Stub

Stub feature rely on spring boot and okhttp3, make sure FeignClient/RestTemplate are using okhttp3.

• Stub REST API.
• Stub Soap API.

Dependencies

1. io.github.openfeign:feign-okhttp.

Gradle

repositories {
    jcenter()
}

dependencies {
    compile 'com.github.wenhao:mushrooms:3.0.8'
}

Maven

<dependency>
    <groupId>com.github.wenhao</groupId>
    <artifactId>mushrooms</artifactId>
    <version>3.0.8</version>
</dependency>

Build

./gradlew clean build

Get Started

Request Matchers

A request matcher can contain any of the following matchers:

• method - string value as a plain text, regular expression.
• path - string value as a plain text, regular expression.
• query string - key to multiple values as a plain text, regular expression.
• headers - key to multiple values as a plain text, regular expression.
• body
  • XPath(example, body: xpath:/Envelope/Body/GetBookRequest[BookName='Java']), without NAMESPACE.
  • XML - full or partial match.
  • JSON - full or partial match.
  • JsonPath(example, body: jsonPath:$.store.book[?(@.price < 10)]), jsonPath syntax

Integrate with Spring boot

1. add application.yml configuration, eg.MushroomsStubConfiguration.java.
2. initialize StubOkHttpClientInterceptor via spring bean config, eg.BeanConfiguration.java.
3. override the OkHttpFeignConfiguration if you're using FeignClient, eg.OkHttpFeignConfiguration.

Full setup

mushrooms:
  stub:
    enabled: true
    failover: true
    stubs:
      - request:
          path: ${REAL_HOST:http://localhost:8080}/stub(.*)
          parameters: 
            - key: [A-z]{0,10}
              value: [A-Z0-9]+
          method: P(.*)
          headers:
            - key: [A-z]{0,10}
              value: [A-Z0-9]+
          body: /stubs/stub_rest_request.json
        response: /stubs/stub_rest_response.json

Stub Configuration

Enabled mushrooms stub and set stub request and response.

Stub REST API

mushrooms:
  stub:
    enabled: true
    stubs:
      - request:
          path: ${REAL_HOST:http://localhost:8080}/stub
          method: POST
          body: /stubs/stub_rest_request.json
        response: /stubs/stub_rest_response.json

Stub Soap API

mushrooms:
  stub:
    enabled: true
    stubs:
      - request:
          path: ${REAL_HOST:http://localhost:8080}/stub/get_book
          method: POST
          body: /stubs/stub_soap_request.xml
        response: /stubs/stub_soap_response.xml

Enabled RestTemplate stub, Customize RestTemplate by using Okhttp3, RestTemplateConfiguration.

@Configuration
public class RestTemplateConfiguration {

  @Bean
  public RestTemplate restTemplate(ClientHttpRequestFactory clientHttpRequestFactory) {
    return new RestTemplate(clientHttpRequestFactory);
  }

  @Bean
  public ClientHttpRequestFactory okHttp3ClientHttpRequestFactory(OkHttpClient okHttpClient) {
    return new OkHttp3ClientHttpRequestFactory(okHttpClient);
  }
}

Generic Configuration

If enabled okhttp stub, enabling feign okhttp client.

feign:
  okhttp:
    enabled: true
  client:
    config:
      default:
        connectTimeout: 5000
        readTimeout: 5000
        loggerLevel: full

Logging

logging:
  level:
    com.github.wenhao.mushrooms: DEBUG

Failover

As Failover is true, will call real endpoint first and return real response if health.
