Robert Muir commented on LUCENE-3731:
-------------------------------------
Thanks for starting this Tommaso:
I was unable to apply the patch (were there some svn-copies?)
But I suggest in general using the BaseTokenStreamTestCase.assertTokenStreamContents/assertAnalyzesTo:
e.g. instead of:
{code}
// check that 'the big brown fox jumped on the wood' tokens have the expected PoS types
String[] expectedPos = new String[]{"at", "jj", "jj", "nn", "vbd", "in", "at", "nn"};
int i = 0;
while (ts.incrementToken()) {
assertNotNull(offsetAtt);
assertNotNull(termAtt);
assertNotNull(typeAttr);
assertEquals(typeAttr.type(), expectedPos[i]);
i++;
}
{code}
you could use:
{code}
assertTokenStreamContents(ts,
new String[] { "the", "big", "brown", ... }, /* expected terms */
new String[] { "at", "jj", "jj", ... }, /* expected types */
{code}
There are also variants that let you supply expected start/end offsets, I think that would be good.
Finally, to check for lots of other bugs (including thread-safety, compatibility with charfilters, etc),
I would recommend:
{code}
/** blast some random strings through the analyzer */
public void testRandomStrings() throws Exception {
Analyzer a = new Analyzer() {
@Override
protected TokenStreamComponents createComponents(String fieldName, Reader reader) {
Tokenizer tokenizer = new MyTokenizer(reader);
return new TokenStreamComponents(tokenizer, tokenizer);
}
};
checkRandomData(random, a, 10000*RANDOM_MULTIPLIER);
}
{code}
If you look at BaseTokenStreamTestCase you will see all of these methods are insanely nitpicky
and find all kinds of bugs in analysis components, so it will really help test coverage I think.

> As discussed in SOLR-3013 the UIMA Tokenizers/Analyzer should be refactored out in a separate module (modules/analysis/uima) as they can be used in plain Lucene. Then the solr/contrib/uima will contain only the related factories.
