SUMMARY
The test suite was spinning up way too many database connections that what's
strictly needed and so the test suite was failing with[0]:
code: "53300", message: "sorry, too many clients already"
EXPERIMENTS
Tried sharing database connection pool across all tests with
async_once[0] but faced:
- IO errors
The connections were probably getting dropped in between tests
- actix Actor errors
The actor was probably not getting initialized before a
a reference to the async_once initialized app
context(crate::data::Data) is retrieved and used
FIX
crate::tests was spinning up an App context
instance(crate::data::Data) for most utility functions, which was
unnecessarily excessive.
Each test now creates an instance of the application context at the
beginning and shared a reference with all test utility functions. So
number of database connections/app context instance = number of unit
tests.

gdb revealed that demo::demo_account_works receives a SIGKILL due to a
failed test. No idea why it didn't fail the usual way. The part where
the test fails hits an endpoint with the wrong datatype payload, it
should have failed with a 404 when the status was asserted but it
didn't. Fixing that fixed#8.
Additionally, all demo user functionality was restructured to include an
abort functionality, which can be used to kill the loop that deletes and
creates demo user throughout the runtime of the app.
