QUESTION
I am writing unit tests for some higher-order logic that depends on writing to an SQLite3 database. For this I am using twisted.trial.unittest
and twisted.enterprise.adbapi.ConnectionPool
.
I am able to create a persistent sqlite3 database and store data therein. Using sqlitebrowser, I am able to verify that the data has been persisted as expected.
The issue is that calls to t.e.a.ConnectionPool.run*
(e.g.: runQuery
) return an empty set of results, but only when called from within a TestCase
.
The problem I am experiencing occurs only within Twisted's trial
framework. My first attempt at debugging was to pull the database code out of the unit test and place it into an independent test/debug script. Said script works as expected while the unit test code does not (see examples below).
This is the script used to initialize the database. There are no (apparent) errors stemming from this file.

function, you're returning self.db.runInteraction(...)
, which returns a deferred. As you've noted, you assume that it waits for the deferred to finish. However this is not the case and it's a trap that most fall victim to (myself included). I'll be honest with you, for situations like this, especially for unit tests, I just execute the synchronous code outside the TestCase
class to initialize the database. For example:
