在运行 junit 测试时模拟物理 Web 服务器

Question

I am searching for a simple framework which is able to mock JSON responses for specific URLs and therefore starts an in-memory server. Eg the framework could start a node.js server or similar.

I need a physical server since the unit tests are running against an external application (using selenium) and this application has a dependency to a JSON interface. The application itself is iPhone-App running inside of simulator and communicates to a REST interface.

Is there an existing framework for this or what would be the best approach given that I need to execute the tests with jUnit.

Answer 1

You can start a stub server, given that you can configure the JSON URL in your client application.

Have a look for example at:

• https://github.com/dreamhead/moco
• https://stubby4j.com

You can start these in your maven build during the pre-integrationtest phase and shut them down in post-integration test phase.

Answer 2

You can use npm package stubby-db . What you need to do is;

1. Install : npm install stubby-db -g
2. Mapping : Create a request response mapping which is quite easy. Specify the path of response file having JSON response.
3. Run the stub server: stubbydb

That's all. However since you just want to run it for your unit tests only which doesn't require much performance, you can also use wiremock . It starts internally, and you never feel like you are running an external application.
