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`).
This test was calling `.load` on model objects, when it should have
been calling `.dump`. This was not working as expected before the
marshmallow upgrade either - the objects returned were errors and not
template versions.
The tests were previously covering a shared function that's now
only used once, so I've inlined it and merged the tests together
with a common naming that's consistent with the code under test.
we add a row in AnnualBilling table whenever a new service is created,
and our billing code assumes this is done. Yet when we were writing
some of the tests, this was not a thing yet, so now we are updating
those tests so they reflect our system well.

This is so we have granular data about billable units and costs
so that we can handle multiple sms rates within one financial
year.
We also cast chargeable_units_used_so_far in that subquery
to integer so we don't have type mismatch.

This is functionally very similar to query_service_sms_usage_for_year,
except this query filters by organisation and returns for all live services
within that organisation.
To ensure that the cumulative free allowance counter resets properly for
each service, we use the `partition_by` flag to group up the window
function[^1]. This magically handles all the free allowances
independently for each service.

This can happen in the following scenario (primarily for letters):
1. A service has a mixture of "delivered" and "sending" letters,
which the status task aggregates into two rows:
sending | 123
delivered | 456
2. After the 7 day retention has passed, only the "delivered" letters
will be archived [^1].
3. The status task now looks at the history table [^2], which means
it only sees the "delivered" letters.
4. The "sending" letters are eventually "delivered" and archived (before
the 10 day aggregation cutoff).
5. But the status aggregation task doesn't run.
This commit fixes (5).

* notify_db fixture creates the database connection and ensures the test
db exists and has migrations applied etc. It will run once per session
(test run).
* notify_db_session fixture runs after your test finishes and deletes
all non static (eg type table) data.
In unit tests that hit the database (ie: most of them), 99% of the time
we will need to use notify_db_session to ensure everything is reset. The
only time we don't need to use it is when we're querying things such as
"ensure get X works when database is empty". This is such a low
percentage of tests that it's easier for us to just use
notify_db_session every time, and ensure that all our tests run much
more consistently, at the cost of a small bit of performance when
running tests.
We used to use notify_db to access the session object for manually
adding, committing, etc. To dissuade usage of that fixture I've moved
that to the `notify_db_session`. I've then removed all uses of notify_db
that I could find in the codebase.
As a note, if you're writing a test that uses a `sample_x` fixture, all
of those fixtures rely on notify_db_session so you'll get the teardown
functionality for free. If you're just calling eg `create_x` db.py
functions, then you'll need to make you add notify_db_session fixture to
your test, even if you aren't manually accessing the session.
this was added five years ago but never used. if we want to bring back
variable rates per client we might as well get a fresh start since a lot
has changed since then.
This slowed me down when making changes to the DAO functions. It's
really not necessary to do 3 * 367 DB insertions for both tests.
Before:
time pytest tests/app/dao/test_ft_billing_dao.py -k for_year
...
pytest tests/app/dao/test_ft_billing_dao.py -k for_year 3.95s user 0.40s system 62% cpu 6.971 total
After:
time pytest tests/app/dao/test_ft_billing_dao.py -k for_year
...
pytest tests/app/dao/test_ft_billing_dao.py -k for_year 1.84s user 0.25s system 69% cpu 3.006 total
This is unnecessary since we now have separate "_variable_rates"
tests that check the behaviour for multiple rates explicitly for
the two types of notifications it affects.
This can be calculated from the "free_allowance_used" field and the
"chargeable_units" field, but having it included separately is more
convenient as it can be used directly in Admin [^1].

This represents the number of chargeable_units that were actually
free due to the free allowance - they won't be included in "cost".
Although the existing calculations in Admin [^1][^2] will still be
correct with a change in SMS rates - it's cost that's the problem
- it makes sense to have all the knowledge about calculating usage
consistently in these two APIs.
Note that the Integer casting is covered by the API-level tests in
test_rest.
