Chris Yang 4260e227dc [ios]Adjust golden test threshold for TwoPlatformViewsWithOtherBackDropFilterTests based on current macOS version (flutter/engine#45891)
TwoPlatformViewsWithOtherBackDropFilterTests is failing on macOS 13 with the same simulator version used in macOS 12. The image diff looks identical and slightly above the threshold. This PR adjusts the threshold for this test temporarily so our CI can run on both macOS 13 and 12. This change can be reverted when we move all our CI to macOS 13

Engine Testing

This directory contains the infrastructure for running tests on the engine, which are most often run by Flutter's continuous integration (CI) systems.

The tests themselves are located in other directories, closer to the source for each platform, language, and variant. For instance, macOS engine unit tests written in objective C are located in the same directory as the source files, but with a Test suffix added (e.g. "FlutterEngineTest.mm" holds the tests for "FlutterEngine.mm", and they are located in the same directory).

Testing the Engine locally

If you are working on the engine, you will want to be able to run tests locally.

In order to learn the details of how do that, please consult the Flutter Wiki page on the subject.
