Lightweight functional testing

摘要

The present invention relates to a method performing a method for functional testing of a data collection system and a computer program product for a message simulator and a computer program product for a verification service apparatus for implementing this method. The method comprises periodically sending by the message simulator to the data collection system running in production environment, batches of sets of messages, where the messages mimic normal client messages. Each message contains a batch identification common to the messages within the specific batch and a unique message counter value. The batch of messages received by the data collection system is checked in the verification service to verify whether the data collection systems operates correctly.
