Regression testing

What is regression testing after an accounting-software update?

Short answer

Regression testing means repeating the relevant tests after an ERP or accounting-software update to confirm that generating, validating, sending and receiving e-invoice XML still works and that the update introduced no unintended changes. It is a recommended operational control, not a statutory obligation under Slovak VAT or accounting law.
