# Test cases fts3atoken-1.* are the warm-body test for the SQL scalar
|
|
# function fts3_tokenizer(). The procedure is as follows:
|
|
#
|
|
# 1: Verify that there is no such fts3 tokenizer as 'blah'.
|
|
#
|
|
# 2: Query for the built-in tokenizer 'simple'. Insert a copy of the
|
|
# retrieved value as tokenizer 'blah'.
|
|
#
|
|
# 3: Test that the value returned for tokenizer 'blah' is now the
|
|
# same as that retrieved for 'simple'.
|
|
#
|
|
# 4: Test that it is now possible to create an fts3 table using
|
|
# tokenizer 'blah' (it was not possible in step 1).
|
|
#
|
|
# 5: Test that the table created to use tokenizer 'blah' is usable.
