When we cloned the repository and started making modifications, we
didn't initially keep tests in step. This commit tries to get us to a
clean test run by skipping tests that are failing and removing some
that we no longer expect to use (MMG, Firetext), with the intention that
we will come back in future and update or remove them as appropriate.
To find all tests skipped, search for `@pytest.mark.skip(reason="Needs
updating for TTS:`. There will be a brief description of the work that
needs to be done to get them passing, if known. Delete that line to make
them run in a standard test run (`make test`).
The provider tests are coupled to actual data in the DB, but we
shouldn't have to overhaul the tests when this changes.
Assuming we don't delete old providers, just testing a subset of
the fixture data should give us enough confidence in the code.
Fixes:
> reduced_provider = providers[identifier]
E KeyError: 'firetext'
Note that the mock return value in the other test was wrong [^1].

i think it's causing havoc with my attempts to mock stuff in the
`app.clients` directory because it's also accessible at that path. the
name's super vague and doesn't explain what it is anyway
it's not acceptable for a constantly failing provider to take 50 minutes
to drain (5x reducing priority by 10). But similarly, we need _some_
delay, or a handful of concurrent failures will completely turn off a
provider, rendering the whole excercise kinda pointless. Setting the
delay before it tries to reduce priority again to one minute is nice
because it means that if one request times out and returns 502, then any
other requests that are in flight at that time will time out before the
one minute is up and not switch, but any requests made after the switch
that take sixty seconds to time out will affect it.
when ORM level changes are made (eg `my_model.my_column = my_value`),
the ORM will read the column definition to see if it should apply any
defaults.The updated_at columns that we use all define
`onupdate=datetime.datetime.utcnow`. We can't patch this out as the
function pointer to the original function has already been grabbed by
this at import time - so freezegun or `mocker.patch` won't work.
So we have to use the query syntax to set the `updated_at` timestamp in
the DB without going through the ORM layer.
making sure that we don't close the transaction early, because we need
to keep the transaction open as it has the with_for_update clause on the
select to lock the table.
also make sure the tests clean up after themselves as they're adding
history rows etc
it now only needs to be used when you're:
* updating providers in ways that will create history (eg through
regular api calls)
* altering more than just priority in test setup (eg setting inactive,
deleting, or adding a provider)
we randomly choose between sms providers now - this means that tests may
sometimes send firetext and sometimes mmg, so we'd need to patch out
different HTTP calls, expect different values in sent_by, etc etc.
To ensure tests are consistent, add a new fixture that is always used by
notify_db_session, which sets the priorities of the sms providers to
100% mmg 0% firetext. if you need to test other values, then you should
set the values manually in the test file
the function no longer makes sense now that we send through both at
the same time. mostly just used in old tests that we'll end up rewriting
shortly anyway
retrive the sms providers from the DB, and decrease the chosen
provider's priority by 10, while increasing the other by 10.
add a check in to ensure we never decrease below 0 or increase above 100
- this is per provider, we don't check that the two add up to 100 or
anything. If the values are outside of this range (eg: set via the UI)
then they'll probably* fix themselves at some point - we've added tests
to document these cases.
Use with_for_update to ensure that the method can only run once at a
time - other invocations of the function will be held on that line until
the currently running one ends and commits the transaction. This doesn't
affect anyone doing things from the UI.
In addition to the existing provider data, we also want return the number of
billable units (muliplied by the rate multiplier) that each SMS provider sent
this month. This will be used on the platform admin providers page.
Since we can no longer get all the information we need from the provider details
schema, this makes a new DAO function to get all the data for the endpoint.
* Add notify user id in config
* Add dao method to get provider history versions along with tests
* BUG: Provider switching did not handle case where priorities were equal. This
* adds a fix to properly cover this case along with tests
