Why do I receive "No such property" in before* and after* logic of domain classes in unit tests?

I notice that any reference to a property is missing when requiring domain classes in grails unit tests.

Somewhere in the Unit Test

mockDomain(Event)

10.times {
    e   = new Event(eventCalendar:ec, title:"$ec - Event $it", details:"some detail", location:"some location", startDate: now, endDate: now+1)
    e.save()
}

Event.groovy

static beforeInsert = {
    if (!endDate) {
        // do something about it
    }
}

Resulting error

No such property: endDate for class: myproj.Event Possible solutions: endDate

groovy.lang.MissingPropertyException: No such property: endDate for class: myproj.Event

1. How can I still create a working test?
2. Why is the stacktrace suggesting the property which it has stated as missing?

You've incorrectly defined your event handler as a static closure:

static beforeInsert = {
    if (!endDate) {
        // do something about it
    }
}

You can't access endDate here because it's (presumably) a non-static property. Change your event handler to be non-static and your problem should be fixed.

def beforeInsert = {
    if (!endDate) {
        // do something about it
    }
}
