How to test broken behavior of LibreOffice with ODT

Hi Experts,

We have setup developer code base for LibreOffice and what we found is for one of ODT file, condition “” EQ “” is becoming 0 when we open odt file in LO 25.8

We opened bug but wanted to see how can we test this kind of scenarios in future ourselves with code base

168858 – Conditional Sections Are Improperly Set to 0 When Opened With LibreOffice

Any pointers on this bizarre behavior

Thanks
Abhi
