After disabling some tests here and there, I found
SwUiWriterTest::testRedlineViewAuthor is the one affecting the execution
of the new test.

I'm not sure why it's happening yet but I do believe it has to do with
the view being set in
https://opengrok.libreoffice.org/xref/core/sw/qa/extras/uiwriter/uiwriter.cxx?r=99d4bf94#5477

I tried to add the following like at the end of the unittest but it
didn't work:

pDocShell->GetViewShell()->GetViewFrame()->GetDispatcher()->Execute(SID_CLOSEWIN,
SfxCallMode::SYNCHRON);

( similar to destroyView in lokhelper <
https://opengrok.libreoffice.org/xref/core/sfx2/source/view/lokhelper.cxx?r=2f72fa98#93
> )

Any idea what is happening and how to solve it? Otherwise I might go
with your second solution and put the test somewhere else.

Cheers
