Question

I’m trying to write a simple integration test, but having some trouble with Domain Objects. I’ve read on unit testing but can’t figure it out.

This is my simple test:

    User user = User.get(1)

    controller.params.userid = "1"
    controller.session.user = user

    controller.save();

The error message is:

groovy.lang.MissingMethodException: No
signature of method: static
com.baufest.insside.user.User.get() is
applicable for argument types:
(java.lang.Integer) values: 1

My guess is that I should mock the user object, but don’t know how.

You say that you’re integration testing, but it looks like you’re unit testing. Is the test under test/integration or test/unit? Unit tests need mocking, but integration tests have an initialized Spring application context and Hibernate, and run against an in-memory database.

This is described in the user guide, which is at http://grails.org/doc/latest/ (you reference an older 1.1 version).

To mock the User class, just call mockDomain with one or more test instances either in setUp or in the test method:

def users = [new User(...), new User(...), ...]
mockDomain User, users

...

User user = User.get(1)
