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.
Recommended step
Verify functionality e-invoice after changing the software version.
Scope of testing
Credit, foreign currency, multiple attachments and so on.
Verification tool
Checking the marketing rules before production.
No legal obligation
The company sets up this procedure itself in the internal control.
Conclusion
Repeat the essential e-invoice tests after material software changes; this is good operational practice rather than a separate statutory duty.
