Re: CppunitTest: different results depending on execution command

[Xisco Fauli <xiscofauli@xxxxxxxxxxxxxxx>]

Hi Michael,

That might explain why another unittest I created for tdf#132944 was
also giving different results locally and in jenkins, See
https://bugs.documentfoundation.org/show_bug.cgi?id=132944#c10

Do you know how I could reset the test to its original state?

I tried to add something like this at the end of testRedlineViewAuthor

const OUString aEmptyAuthor("");
pView->SetRedlineAuthor(aEmptyAuthor);
pDocShell->SetView(pView);

or

SwEditShell* const pEditShell(pDoc->GetEditShell());
while(pEditShell->GetRedlineCount())
    pEditShell->AcceptRedline(0);

but the new unittest is still failing.

Thanks in advance
