ruby - Rails - is writing tests for testing CRUD operations worth it, if so integration or unit? -

i have lengthy simple form allows users update products, nil fancy, displays fields come in text values & updates corresponding database table.

is regular practice write tests crud operations such this? of import form works used everyday - there not much go wrong. have time this, don't want wasting time either or create future maintenance of test suite overly difficult.

if cover tests, should utilize integration (cucumber) or unit (rspec) tests?

thanks advice!

in theory believe supposed utilize both: rspec test each layer in isolation, cucumber test whole stack. if think piece of app straight-forward warrent slavish adherence principles, recommend stick integration tests. it's of import know if isn't working right, , imo cucumber lone should suffient purpose.

of course of study more complex areas of app, want utilize mixture of each.

ruby cucumber

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...
