Running 1000 tests in 1s
Most code doesn't require the amount of test isolation modern test runners apply by default. If you only opt into the amount of isolations you need, you can easily run 1000 tests in 1s.

Which Kinds of Tests Should I Write?
Programmers routinely ask me for advice on which kinds of tests they ought to write: unit vs. functional, fast vs. slow, big vs. small. They keep saying

The Saff Squeeze:
Debug with automated tests: it's systematic, it leaves a record of what we've learned, and it's boring in the best possible ways.

The Fast Way to Test Django () Callbacks
Django’s transaction.on_commit() hook is useful for running tasks that rely on changes in the current database transaction. The database connection enqueues callback functions passed to on_commit, and executes the callbacks after the current transaction commits. If the transaction is rolled back, the callbacks are discarded. This means they act if-and-when the final version of the data is visible to other database connections.

I have never seen a case where mocking a database was a good idea.
Stay with me, for whatever short-term gains one gains, you lose in long-term maintainability because everyone does it differently and it's always the most complex code in your codebase.
