Comment 37

[Julian Descottes [:jdescottes]]

So far I can't reproduce it locally and there is nothing odd about this test.
We are opening a tab on a simple data:text:html URI. Then we open the "rule view" using the usual helpers, which should normally wait until the toolbox and the panel are visible.

However, looking at the failure screenshots, it seems we get a toolbox in various states of initialization:

• markup view not rendered yet: https://firefoxci.taskcluster-artifacts.net/POHke-JJTqWSOXUqSu5bZA/0/public/test_info/mozilla-test-fail-screenshot_bf14x6xc.png
• no markup view, no toolbox buttons: https://firefoxci.taskcluster-artifacts.net/LZv5evfRT6So2AwohDJB1Q/0/public/test_info/mozilla-test-fail-screenshot_uuk751c8.png
• no toolbox at all: https://firefoxci.taskcluster-artifacts.net/IluxWcEESKeBrPon5N0_Fw/0/public/test_info/mozilla-test-fail-screenshot_pzwtmmk0.png
• markup view rendered but wrong element selected: https://firefoxci.taskcluster-artifacts.net/MIsc5rpeSH2pjKYeu_Yd_A/0/public/test_info/mozilla-test-fail-screenshot_bcze9qdb.png

I am not sure how much we can trust those screenshots. If they are taken while the test is being shutdown, it's also possible that the toolbox has started destroying itself?

It fails frequently on try when running the whole suite (devtools/client/inspector/rules/test/browser_part2.ini) so at least I should be able to make progress. Taking the bug.
