asp.net - Is this the right way to handle javascript alert dialogs using WebDriver? -

it seems in asp.net webdriver api, executing next when there no javascript alert nowadays results in exception:

browser.switchto().alert();

ie , ff both throw webdriverexception, chrome throws invalidoperationexception.

so far, code seems work:

try { var alert = browser.switchto().alert(); if (alert != null) alert.dismiss(); } grab (webdriverexception) { // alert not nowadays in ie or ff } grab (invalidoperationexception) { // alert not nowadays in chrome }

is there way check alert dialog present, without having grab exception?

the actual reply here no, must grab exception. logic behind design of api should aware of browser state expect. if expect alert appear, should able utilize switchto() switch , handle it. if expect alert appear, , utilize switchto() , not present, exceptional condition, , exception thrown. normal (non-exceptional) case not expect alert, , there no corresponding method alert not beingness displayed. incidentally, same logic employed findelement(). can argue wrong logic beingness employed api designers, way current api implemented.

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...
