I was able to reproduce the image failure at both Mac and iOS ToT running the test as follows:

run-webkit-tests fast/text/accessibility-bold-system-font/accessibility-bold-system-font-2.html

The test was originally introduced at commit 189770@main, the history shows that it has been disabled for some time and then was re-enabled at commit 251883@main and has been failing ever since being re-enabled.

Based on https://github.com/WebKit/WebKit/commit/3e3f9ab0f79b58eb597037a6de8ebf192ddc1728#diff-0b438e462819a7b0d06250189152c7bcfb07b7c39acd73938bdfccc7b25b8058R5323, I think the intention was for this test to continue failing on macOS. This is surfacing because this is an image failure instead of a text failure, so the [ Pass Fail ] expectation isn't suppressing it.

Myles, since these tests aren't expected to pass on macOS, is there any reason we shouldn't just skip them?

In this Pull Request, we have opted to [ Skip ] these tests for all platforms except iOS. This was because the previously set expectations mentioned that Accessibility Bold only exists on iOS. So in short, we've skipped them for all platforms. Then for iOS we re-enabled them by adding expectations.

This one is passing for iOS, so we set the expectation to [ Pass ] for this one:
fast/text/accessibility-bold-system-font/accessibility-bold-system-font-3.html


The initial test mentioned in this bug is a constant Image Failure for iOS, so we have marked the following test as [ Pass ImageOnlyFailure ] for iOS:
fast/text/accessibility-bold-system-font/accessibility-bold-system-font-2.html


The final test is a text failure, and has been marked as [ Pass Failure ] for iOS:
fast/text/accessibility-bold-system-font/accessibility-bold-system-font.html 

This is the DIFF for that text failure:

-This test makes sure that text using the accessibility bold functionality has the correct weight.
-
-On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".
-
-
-PASS window.getComputedStyle(target).getPropertyValue('font-weight') is "400"
-PASS successfullyParsed is true
-
-TEST COMPLETE
-Hello

In general, it's better to mark flakey rather than skip, because flakey at least makes sure the tests don't crash.
