44 # function fts3_tokenizer(). The procedure is as follows:
46 # 1: Verify that there is no such fts3 tokenizer as 'blah'.
48 # 2: Query for the built-in tokenizer 'simple'. Insert a copy of the
49 # retrieved value as tokenizer 'blah'.
51 # 3: Test that the value returned for tokenizer 'blah' is now the
52 # same as that retrieved for 'simple'.
54 # 4: Test that it is now possible to create an fts3 table using
55 # tokenizer 'blah' (it was not possible in step 1).
57 # 5: Test that the table created to use tokenizer 'blah' is usable.
