The `travel_to` helper didn’t support subsecond time traveling in order
to prevent problems with external services, such as MySQL. This,
however, makes it impossible to test features that use durations less
than a second ("subsecond").
This therefore allows `travel_to` to stub `Time.now` with the accurate
time passed to it as `date_or_time` if the `with_usec` optional argument
is set to true:
Time.now.inspect # => 2022-01-05 22:36:54.613371959 +0000
travel_to(0.1.seconds.from_now, with_usec: true)
Time.now.inspect # => 2022-01-05 22:36:54.713371959 +0000
Ruby 3.1 introduced an optimization to string interpolation for some
core classes in b08dacfea3.
But since we override `to_s` in some of those core classes to add behavior
like `to_s(:db)`, all Rails applications will not be able to take advantage
of that improvement.
Since we can use the `to_formatted_s` alias for the Rails specific behavior
it is best for us to deprecate the `to_s` core extension and allow Rails
applications to get the proformace improvement.
This commit starts removing all the `to_s(:db)` calls inside the framework
so we can deprecate the core extension in the next commit.
`assert_raise` does not check error message. However, in some tests,
it seems like expecting error message checking with `assert_raise`.
Instead of specifying an error message in `assert_raise`, modify to use
another assert to check the error message.
Closes#27614
Previously when calling `now` on a subclass of e.g. `Time` it would return an instance of `Time` instead of returning an instance of the subclass. This way, we always return the correct class.
The minitest stubs were conflicting with the time travel stubs so the
travel_back method call in the teardown block was actually keeping the
time stubbed.
as this can lead to confusing time stubbing.
Instead of:
travel_to 2.days.from_now do
# 2 days from today
travel_to 3.days.from_now do
# 5 days from today
end
end
preferred way to achieve above is:
travel_to 2.days.from_now
# 2 days from today
travel_back
travel_to 5.days.from_now
# 5 days from today
