executeUpdate() not updating on grails spock-integration testing

问题

hi i am new to grails testing. Willing to do integration test as below but problem is that executeUpdate() seems not updating the value

How to do integration testing for executeUpdate('update query goes here') ??

Please help suggest me Sample code is given for problem demo. Thanks in advance.

def "for given merchantTier Id update merchantTier value"(){
    setup:
    def merchantTier = new MerchantTier(              
            value:1.11).save(flush: true) //it saves merchantTier

    when:"when update with setProperty"
    testData = editWithSetProperty(merchantTier.id) //id is passed

    then:"it updates data and test is success"
    merchantTier.value == 2.22

    when:"executeUpdate query is used instead"
    testData = editWithExecuteUpdate(merchantTier.id)// id is passed

    then:"it does not update the data and test is failed"
    merchantTier.value == 3.33
}

def editWithSetProperty(id) {
    def merchantTier = MerchantTier.get(id.toLong())
    merchantTier.setValue(2.22.toDouble())
}

def editWithExecuteUpdate(id) {
        MerchantTier.executeUpdate('update MerchantTier mt set mt.value=:mrValue where mt.id=:mtId', [mrValue: 3.33.toDouble(), mtId: id.toLong()])
}

回答1:

as you are updating through executeUpdate you again need to fetch the object from database so try returning the fresh object fetched from database in editWithExecuteUpdate

def editWithExecuteUpdate(id) {
    MerchantTier.executeUpdate('update MerchantTier mt set mt.value=:mrValue where mt.id=:mtId', [mrValue: 3.33.toDouble(), mtId: id.toLong()])
    merchantTier = MerchantTier.get(id)
}

once done then you will have testData containing merchantTier object in when: clause

so in then: clause have

 testData.value == 3.33

hope this make sense. Thanks

Edit - Additional Way

def editWithExecuteUpdate(id) {
    def updatedRecords = MerchantTier.executeUpdate('update MerchantTier mt set mt.value=:mrValue where mt.id=:mtId', [mrValue: 3.33.toDouble(), mtId: id.toLong()])
    return updatedRecords
}

so in then: clause have as due to executeUpdate only one row should be updated based on unique id and also fetch fresh object again and check the persisted value

 testData == 1
 def freshMerchantTier = MerchantTier.get(merchantTier.id)
 freshMerchantTier.value == 3.33

Try this way once, please. Thanks
