Grails unit tests not recognizing .save() on a domain class

Question

I am trying to be a good little programmer and set up Unit tests for my Grails 2.2.3 app. The unit tests that use GORM's injected `.save()` method are apparently not persisting to the mock test DB. For an example, here is what one test consists of: ``` @TestFor(TermService) @Mock(Term) class TermServiceTests { void testTermCount() { def t = new Term(code: "201310").save(validate: false, flush: true, failOnError: true) println "Printing Term: " + t.toString() assert 1 == Term.count() // FAILS assert service.isMainTerm(t) // FAILS } } ``` I did a `println` that ends up printing `Printing Term: null`, meaning the Term did not save and return a Term instance. The first assertion is false with `Term.count()` returning 0. Does anyone know why this might be? I have a mock Term and TermService (via the TestFor annotation, I believe), so I'm not quite sure why this wouldn't work. Thanks! Edit: Here is my Term class. ``` class Term { Integer id String code String description Date startDate Date…

Accepted Answer

Looks like `id` generator is `assigned` since you have mentioned about using legacy database. Plus `id` is not bindable by default in domain class (map construct won't work for id). So, I think you have to end up using like below:

```
def t = new Term(code: "201310")
t.id = 1
t.save(...)
```
