Hi all,

I'm still working on https://gerrit.libreoffice.org/#/c/59269/. The
suggested range-based for-loops work well. Now I try to make a unit test
as suggested by Tomaž.

I have a test file "tdf101242_without_settings.odg", which has the
attributes in the <draw:layer> elements in styles.xml and has no
visible/printable/locked items in settings.xml. I want to load the file,
then save it, then verify that the attributes are still there in
styles.xml. After that works, make a test to verify, that the old kind
items in settings.xml are written correctly.

Sounds promising.

Is there any example, where I can see how to do that?

Probably not.. usually just look at other tests and do what they do.
The problem is that most of them are for impress and not draw. I have
struggled with some tests in the past too.

I have tried a start like
void SdMiscTest::testTdf101242_ODF2ODF()
{
     ::sd::DrawDocShellRef xDocShRef =
Load(m_directories.getURLFromSrc("/sd/qa/unit/data/tdf101242_without_settings.odg"),
ODG);

I would do it like it is done in test SdExportTest::testTdf113822 in
export-tests.cxx and SdExportTest::testEmbeddedText().

    utl::TempFile tempFile;
    sd::DrawDocShellRef xShell =
loadURL(m_directories.getURLFromSrc("/sd/qa/unit/data/tdf101242_without_settings.odg"),
ODG);
    xShell = saveAndReload(xShell.get(), ODG, &tempFile);
    xmlDocPtr pXmlDoc = parseExport(tempFile, "styles.xml");
    assert with xpath ...
    xDocShRef->DoClose();

Is there a human readable way to see, what I get there?

Not that I know of. You need to hunt down the temporary file and look
at it. You can look at the path of the tempFile -
tempFile.GetURLPath();

Then I have continued (mimicking what I have seen in other places) with:
uno::Reference<lang::XComponent > xComponent(xDocShRef->GetModel(),
uno::UNO_QUERY);
     uno::Reference<frame::XStorable> xStorable(xComponent, uno::UNO_QUERY);
     utl::MediaDescriptor aMediaDescriptor;
     aMediaDescriptor["FilterName"] <<= OUString("draw8");
     utl::TempFile aTempFile;
     aTempFile.EnableKillingFile();
     xStorable->storeToURL(aTempFile.GetURL(),
aMediaDescriptor.getAsConstPropertyValueList());

This may not be needed - look at my example.

I see a temp file in C:\cygwin64\tmp\. But it has mimetype
application/vnd.oasis.opendocument.presentation and the attributes in
the <draw:layer> elements are wrong.

That's weird - I hope it works with my example.

My idea was to use something like
xmlDocPtr pXmlDoc = parseExport(aTempFile, "styles.xml");
OString
sPathStart("/office:document-styles/office:master-styles/draw:layer-set/draw:layer");
     assertXPath(pXmlDoc, sPathStart +
"[@draw:name='backgroundobjects']", "draw:protected", "true" );
I get something in pXmlDoc. How can I see, what I have got? I cannot get
nodes from it, e.g
getXPathNode(pXmlDoc,OString("/office:document-styles")) or
getXPathNode(pXmlDoc,"/office:document-styles") is already empty.

I solve this by constructing the path step by step, until it is what I want.
For example:

first try:
assertPath("/office:document-styles/");

second try I would add : master-styles:
assertPath("/office:document-styles/office:master-styles/");

third try I would add layer-set:
assertPath("/office:document-styles/office:master-styles/draw:layer-set/");
....

Obviously I need help.

Kind regards
Regina
