Rubén NorteandFacebook GitHub Bot 6b4af382c2 Apply better default options in benchmarks (#53320)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/53320

Changelog: [internal]

This improves the defaults the options related to minimum number of iterations and test duration in benchmarks.

If you indicate a minimum duration, we set the minimum number of iterations so the duration is honored. We do the same if what's specified is the number of iterations.

This is useful when you want to make sure all the tests in a benchmark suite use the same number of iterations without having to explicitly set the time to 0 in all of them.

It also changes the default for warmup iterations to be just 1 (that's enough to load all modules and all the code into memory).

Rubén NorteandFacebook GitHub Bot 6c37b5b682 Improve typing of benchmark functions (#53322)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/53322

Changelog: [internal]

This changes the types for benchmark functions to improve safety:
1. It makes the return object be an object instead of an interface, to catch when `overriddenDuration` is misspelled.
2. It makes the function always synchronous, as asynchronous tests aren't supported in Fantom (even though they are in `tinybench`).

Rubén NorteandFacebook GitHub Bot e8bf982bac Support overriddenDuration in Fantom benchmarks (#53250)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/53250

Changelog: [internal]

This updates the types for Fantom benchmarks to support the new `overriddenDuration` option from `tinybench`.

It also exposes a new method in the benchmark namespace to access the same timestamp used in benchmarks.

# Changelog:

This adds an extra "ranking" report when running Fantom benchmark vs different React Feature flag configurations.

It can be very useful when implementing some particular optimization, to streamline the before/after comparison wit this optimization enabled/disabled.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52831

# Changelog
[Internal] -

The corresponding `testWithArg` API is similar to the existing `test` one for the Fantom benchmarks, except it would allow to run the same test several times in a parametrized manner, with the set of parameters specified as an array (for now, of numbers).

This allows to easily implement testing patterns such as we have in a View benchmark test, whereas we have a mostly duplicated test body doing a similar thing with 100, 1000, 1500 view component instances etc.

Just a small quality of life improvement. It forces the test functions in benchmarks to have the name of the test case if it's an anonymous function, so it shows better in stack traces.
