Unit testing – use findall to generate simulated Grails methods for missingmethodexception

def retrieveEatenFood(String token,String addedDate) {     

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;  
    }
}

An attempt was made to emulate the above method, but findall continues to generate an exception

This question is valid! Now I need to write tests for it, and I always get this exception Anyone can help me!

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)

Solution

I will use descriptive names to move the query to the consumer domain class, such as

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 phone is simple

def list = Consumer.findAllEatenByDate(addedDate)

You can easily imitate

def foods = [new EatenFood(...),new EatenFood(...),...]
Consumer.MetaClass.static.findAllEatenByDate = { String date - > foods }

Be sure to test the finder method in consumer integration testing
