I am very new to development and even more in the dark when it comes to
Ruby, but I am still having fun. ;-) I also apologise for the long
snippets of code in this post.

I am trying to test a database migration using Ruby and the built in
Test framework.

I am stuck however on a particular problem and it relates to control
flow and the dynamic use of 'define_method' to create multiple Tests if
an assert_equal 'fails' thus jumping out of a loop and stopping all
future tests.

I found what I thought was the solution from this post:

http://www.ruby-forum.com/topic/204730

One I notice however is it will not execute the define_method block
until it has executed all of the exterior loops.

My code is as follows:

class TestSuite < Test::Unit::TestCase

#Build a hash of Source Database columns and target Database columns

companyRRAccessToBeacon = Hash.new
companyRRAccessToBeacon['company_id'] = 'ID'
cmpanyRRAccessToBeacon['ultimate_parent_id'] = 'GlobalUltimateID'
companyRRAccessToBeacon['fullname'] = 'Name'
companyRRAccessToBeacon['turnover_curr'] = 'TurnoverCurrencyTypeID'
companyRRAccessToBeacon['turnover'] = 'TurnoverAmount'
companyRRAccessToBeacon['u_size_code'] = 'CorporateSizeTypeID'
companyRRAccessToBeacon['corp_status_id'] =
'CorporateOwnershipTypeID'
companyRRAccessToBeacon['created_user'] = 'RowCreatedBy'
companyRRAccessToBeacon['created_datetime'] = 'RowCreatedDate'
companyRRAccessToBeacon['last_modification_by'] = 'RowModifiedBy'
companyRRAccessToBeacon['last_modification_date'] =
'RowModifiedDate'
companyRRAccessToBeacon['off_limits_id'] = 'OffLimitsID'

#Connect to the RRAccess and Beacon databases
rraccesshandle = connectrraccessdb
beaconhandle = connectbeacondb


#Companyrowdata stores the Data Driven tests used for the test
below.
companyrowData =
getXlsRowData("C:\\Users\\ecucropc\\Documents\\Visual Studio
2008\\Projects\\DataSynchronisation\\DataSynchronisation\\Company
Data.xls", "Company", "A1:L3")

#Loop through each record returned in the Data Driven Test set.
companyrowData.each do | companydata |
puts "In #{companydata} loop"
#If no Company records are returned then run the test.
companydata["company_id"] != ""
recordtofetch = companydata["company_id"]

#Get the common RRAccess Company columns
sqlRRaccessValues = (getDBValue(rraccesshandle, "select
company_id, ultimate_parent_id, fullname, turnover_curr, turnover,
U_Size_Code, corp_status_id, created_user, created_datetime,
last_modification_by, last_modification_date, off_limits_id from
RRAccessLive.Company WHERE Company_id = ?", recordtofetch))

#Get the common Beacon Company columns
sqlBeaconValues = (getDBValue(beaconhandle, "select ID,
GlobalUltimateID, Name, TurnoverCurrencyTypeID, TurnoverAmount,
CorporateSizeTypeID, CorporateOwnershipTypeID, RowCreatedBy,
RowCreatedDate, RowModifiedBy, RowModifiedDate, OffLimitsID from
BeaconLive.Company WHERE ID = ?", recordtofetch))

#For each HashMap pair get the values from the RRAccess and Beacon
databases and then
#loop through and perform the comparison test.

companyRRAccessToBeacon.each {|key, value|
puts "Inside each loop #{companyRRAccessToBeacon[key]}"
rrAccessColumnValue = sqlRRaccessValues[key]
rrBeaconColumnValue = sqlBeaconValues[value]

#This dynamic define_method is used to create many tests.

define_method ("test_company_" + companyRRAccessToBeacon[key])
do
puts "Inside assert_equal loop for
test_company_#{companyRRAccessToBeacon[key]}"
assert_equal sqlRRaccessValues[key], sqlBeaconValues[value]
end
}
end
end


The output of this is as follows:

If I comment out the 'define_method' block of code, it will continue
where I was expecting it to go.

Any help would be greatly appreciated.
