如何在grails中模拟命名查询？

Question

I've following problem in grails 2.1.0. I've domain which has named query. In service I call list() method on result of this named query:

List result = Domain.namedQuery(someParams).list()

So, I'd like mock result in my service's unit test. Is there any option to do it?

I believe you can through altering the metaclass. Just be sure to @Mock the class as well so you don't get test pollution:

Domain.static.metaclass.namedQuery = { someParams ->
    // Assert and return data
}

Also be sure that you match the type and number of params exactly or it may not work.
