我需要为Jersey Rest Web服务编写Junit测试用例..请帮助我或发布示例代码？

Question

This is the code for which I am looking to write Junit test cases--

@GET 

@Path("/get")

@Produces("application/json")

public User getUser() 
{

    User user= new com.rest.rahul.User();

    user.setEmpid("12");
    user.setEmail("DJ@gmail.com");
    user.setName("DJ");
    return user;

}

Answer 1

What do you want to unit test? I wouldn't bother with unit testing simply setters. But if you want to test the JSON output, you're actually looking for something like an an integration test. A test that bootstraps your application, sets up the webservice and then calls the getUser method. Take a look at https://blog.codecentric.de/en/2012/05/writing-lightweight-rest-integration-tests-with-the-jersey-test-framework/

Answer 2

Testing a web service with JUnit involves starting up the web service inside the test environment, performing the request, validating the response and then shutting it down.

You can use Jersey's REST Client to perform a request on a server that comes up when the test runs. Get the response and Assert your required conditions on the response object.
