Mocking grails method that uses a findAll, Generating a MissingMethodException - unit-testing

Question

def retrieveEatenFood(String token, String addedDate) {
def consumer = Consumer.findByMobileToken(token)
if(consumer != null) {
def efList = []
def list = consumer.findAll("from EatenFood as ef where date(ef.dateAdded) = date(:da)",[da:sdf_long.parse(addedDate)])
list.each{
def eatenList = [:]
eatenList.put("foodType",it.food.name)
eatenList.put("sequenceNumber",it.sequenceNumber)
eatenList.put("eatenDate", it.eatenDate)
eatenList.put("DateAdded",it.dateAdded)
efList.add(eatenList);
}
return efList;
}
}
Trying to mock the above method, but the findAll keep generating an exception.
This issue it works! Now i need to write the test for it and i keep getting this exception. Can anyone help me please!
groovy.lang.MissingMethodException: No signature of method: carrotdev.Consumer.findAll() is applicable for argument types: (java.lang.String, java.util.LinkedHashMap) values: [from EatenFood as ef where date(ef.dateAdded) = date(:da), [da:Sun Feb 13 01:51:47 AST 2011]]
Possible solutions: findAll(groovy.lang.Closure), find(groovy.lang.Closure)

Answer 1

I would move the query to the Consumer domain class with a descriptive name, e.g.
static List<EatenFood> findAllEatenByDate(String date) {
consumer.findAll(
"from EatenFood as ef where date(ef.dateAdded) = date(:da)",
[da:sdf_long.parse(addedDate)])
}
Then the call is simply
def list = Consumer.findAllEatenByDate(addedDate)
and you can mock that easily with
def foods = [new EatenFood(...), new EatenFood(...), ...]
Consumer.metaClass.static.findAllEatenByDate = { String date - > foods }
Be sure to test the finder method in your Consumer integration test.
