Ever had a test pass locally but fail randomly in CI? That's what happened to me when testing timestamp fields.
The issue? Date::now() gets called twice - once in your code, once in your test - and those milliseconds add up.
The fix is simple: freeze time with Date::setTestNow() or $this->freezeTime() before making requests.
No more flaky tests, just reliable assertions.

Cool.

One extra practice I’ve found useful is using CarbonImmutable in tests and domain code.

Yeah, nice.
When you use Date::now(), this can be simply configurable via provider, like Date::use(CarbonImmutable::class).
