["Brian Matzon" <brian@xxxxxxxxx>]

I'm having some problems with my BTranslatorRoster test. Does anybody 
have a clue to the following:

1)
virtual status_t AddTranslators(const char *load_path = NULL)
this method may return B_BAD_VALUE if the supplied path is invalid.
I have tried all sorts of strange paths to make it return that value, 
but have been unable to make it
return B_BAD_VALUE (even '?' doesn't work...)

2)
BTranslatorRoster *Instantiate(BMessage *from)
This is the archivable method, wich returns a BTranslatorRoster from a 
BMessage.
The docs state:
"Returns a new BTranslatorRoster object, allocated by new and created 
with the version of the constructor that takes a BMessage archive."
The following works:
  BMessage translator_message;
  translator_message.AddString("be:translator_path", "/boot/home/config
/add-ons/Translators");
  translator_roster = new BTranslatorRoster(&translator_message);
However this doesn't work:
  BMessage translator_message;
  translator_message.AddString("be:translator_path", "/boot/home/config
/add-ons/Translators/");
  translator_roster = (BTranslatorRoster*) 
BTranslatorRoster::Instantiate(&translator_message);
Why Why Why ???

3)
The current (BTranslatorRoster) test is encapsulated in a 
TranslatorRosterTest object, which
has a method called <method_to_test>Test. It hasn't yet been converted 
to the Unit framework
(nor have my other tests). So my tests are all text based, and so will 
the unit tests be.
How do I then test the:
  virtual status_t MakeConfigurationView(translator_id forTranslator, 
BMessage *ioExtension, BView **outView, BRect *outExtent) 
? 
I cannot even create a BView since I am not a BApplication...
Or for that matter - how do I test visual stuff (ie. non measurable 
stuff)?

4)
When translating from tga to bmp why does the following not work?
  BFile input("./data/images/image.tga", B_READ_ONLY);
  BFile output("./data/images/image.out.bmp", B_WRITE_ONLY | 
B_CREATE_FILE | B_ERASE_FILE);
  roster->Translate(&input, NULL, NULL, &output, B_BMP_FORMAT);
I always get a B_NO_TRANSLATOR status_t back... *ponder*

Hope someone can help...
