resource descriptions in unit tests [message #879607]

Hi!

I tried to write unit tests to check the descriptions for the resources, but I can't make it work with models created from strings.

	
val module = parser.parse('''
     code here
''')
val res = module.eResource
val descriptionIndex = indexProvider.getResourceDescriptions(res)

The descriptionIndex is always empty. I suppose this information is created by the builder and I have to call it first, but how do I do that? Or maybe I am doing it all wrong?

best regards,
Vlad

I found the problem: I am declaring several file extensions for the language files and the ParserHelper uses their concatenation when creating a synthetic name for a resource.

	@Inject
	@Named(Constants.FILE_EXTENSIONS)
	public String fileExtension;

I suppose that parsing the value and taking the first extension will fix this. Something like

	protected URI computeUnusedUri(ResourceSet resourceSet) {
		String name = "__synthetic";
                String ext = firstItem(fileExtension)
		for (int i = 0; i < Integer.MAX_VALUE; i++) {
			URI syntheticUri = URI.createURI(name + i + "." + ext);
			if (resourceSet.getResource(syntheticUri, false) == null)
				return syntheticUri;
		}
		throw new IllegalStateException();
	}

	private String firstItem(String list) {
	    list = list.trim();
	    int ix = list.indexOf(',');
            if(ix<0)
                return list;
	    return list.substring(0, ix);
	}

best regards,
Vlad
