3 UI tests fail since I20220420-1800 about eclipse.platform.ui

[jonahgraham]

I can see how UIComparePreferencesAuto.testCompareViewersPref was caused by the mentioned commit, and @T-Svensson and I have provided a PR for that (#31). But the other two failures do not fail when I run locally, and I can't understand why they would fail because of that change. I'll look at the 20220421 results tomorrow.

Merged #31, thanks @jonahgraham

The 20220421 still has same failures and the PR #31 build results are gone already :-(

Since I can't reproduce locally, I will create some dummy PRs to see if I can debug the problem that way.

These tests:

• DeprecatedUIPreferencesAuto.testFieldEditorEnablePref
• DeprecatedUIPreferencesAuto.testFontEditorsPref

only failed if run after:

• UIComparePreferencesAuto.testCompareViewersPref

So the fix in #31 does fix all of the above three cases.

In PR #36 I have provided the test fix to make sure tests clean up after themselves a bit better. See details in the PR.

Seem to fixed all the fails, thanks Johan.
