Looks good.

Why the switch to the prod environment though, isn't the test env exactly for this?

Why the switch to the prod environment though, isn't the test env exactly for this?

That's an interesting question.

My point of view: in off-dart we're not here to test the server's own TEST env, we're here to test if what we coded works in the normal conditions (PROD), as integration or functional tests.
We are virtually forced to run some tests "not on PROD" though, when we save data.
Besides, the TEST env is rather unstable (not a big deal, it's a TEST env), and I prefer to crash the tests with our own bugs with PROD data than because of a test platform instability.

We could also:

1. test whatever changed in server TEST that is not yet in server PROD (that would mean calling also in TEST our current tests in PROD), a bit like non regression tests
2. completely ignore what the server says and use fake http calls - that's what some tests were about (and I got rid of them because they were actually testing jsonDecode), more like unit tests.

Btw, thank you @M123-dev for the review!
