functional testing - how to test playframework's tag and do I need do that -

when create new playframewor's tag. need create test (assuming utilize tdd)? , how possible , best practice doing tests tags in general?

for illustration there piece of code utilize tag "my_tag":

#{my_tag param1:value1, param2:value2 }

if think tag little.. piece of presentation renders on page use. should test how handle parameters , how render html?

how my_tag implemented? html/tag file or in code fasttag?

if my_tag defined in html/tag file general guidance don't want set lot of logic in them. maybe improve testing/validating source of value1 , value2 , making sure my_tag never gets bad value1 or value2 (assuming have pretty tight command of using my_tag.

if my_tag implemented in code fasttag, code can complex want. in case, want write tests exercise execution paths in fasttag logic. having test page of:

#{my_tag param1:badvalue1, param2:value2 } #{my_tag param1:value1, param2:badvalue2 } #{my_tag param1:badvalue1, param2:badvalue2 } #{my_tag param1:value1, param2:value2 } ....

to test many happy , sad paths my_tag can.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
