Question

I have two testing questions. Both are probably easily answered. The first is that I wrote this unit test in Grails:

void testCount() {
    mockDomain(UserAccount)

    new UserAccount(firstName: "Ken").save()
    new UserAccount(firstName: "Bob").save()
    new UserAccount(firstName: "Dave").save()

    assertEquals(3, UserAccount.count())
}

For some reason, I get 0 returned back. Did I forget to do something?

EDIT: OH, I understand. The validation constraints were violated, so they didn’t store. Is there any way to get some feedback here? That’s a really crappy thing to have happen….

The second question is for those who use IDEA. What should I be running – IDEA’s junit tests, or grails targets? I have two options.

Also, why does IDEA say that my tests pass and it provides a green light even though the test above actually fails? This will really drive me nuts if I have to check the test reports in html every time I run my tests…..

Help?

Answer 1

I always do object.save(failOnError: true) in tests to avoid silent failures like this. This causes an exception to be thrown if validation fails. Even without a real database in a unit test, most of the constraints will be checked, although I prefer to use integration tests if I want to test complex relationships between domain objects.
