Groovy HTTPBuilder Mocking the Response

Question

I am trying to figure out how to write my Test cases for a service I am going to write.

The service will use HTTPBuilder to request a response from some URL. The HTT

Here's a minimal example of a mock HttpBuilder that will handle your test case:

class MockHttpBuilder {
    def result
    def requestDelegate = [response: [:]]

    def request(Method method, Closure body) {
        body.delegate = requestDelegate
        body.call()
        if (result)
            requestDelegate.response.success()
        else
            requestDelegate.response.failure()
    }
}

If the result field is true, it'll invoke the success closure, otherwise failure.

EDIT: Here's an example using MockFor instead of a mock class:

import groovy.mock.interceptor.MockFor

def requestDelegate = [response: [:]]
def mock = new MockFor(HttpBuilder)
mock.demand.request { Method method, Closure body ->
    body.delegate = requestDelegate
    body.call()
    requestDelegate.response.success() // or failure depending on what's being tested
}
mock.use {
    assert isOk() == true
}
