Section 06 - Post MDR Day 1 Testing
6.1 Overview of Post MDR Day 1 Testing
CHESS users will have the opportunity to test a number of business workflows in the ‘To be’ Production Environment following each MDR weekend. The window of testing following a dress rehearsal event will be a test phase referred to as ‘post MDR day 1’ testing. It is expected that all activity can be conducted on the Monday system day. The list of possible scenarios can be found in section 6.2, which includes activity following the Monday settlement.
Post MDR day 1 testing is aimed to provide CHESS users with the ability to test supported scenarios with production data. This phase is not a parallel test and will not be expected to reconcile to production.
ASX is planning to run settlement as part of Post MDR day 1 activities. This is to allow clearing and settlement participants to consume the messages created by settlement batch and ensure they are successfully processed by back office systems. The movement of units and cash will vary from that of production as the pre-settlement activities (such as bilateral matching) will be different. It is therefore important for clearing and settlement participants to understand results will be different (and potentially significantly) to production but that the objective of the test is to ensure back office systems can support the output of settlement messages even if there is a high level of settlement fails.
Similar to other phases of Industry Testing, a Post MDR Day 1 Guide to Testing Services will be published externally alongside the MDR overview. This will provide information on how this phase will be coordinated depending on the number of CHESS users involved. These documents be delivered in accordance to Section 6.4 of the Industry Test Strategy.
