Hi Allessia,
To add to Honza's comment https://bugzilla.mozilla.org/show_bug.cgi?id=1732305#c16

Since this might be failing intermittently locally try ./mach test browser_net_url-preview.js --headless --verify to reproduce the error.

Also the issue might relate to the fact that this request you are trying to reach here might not exist https://searchfox.org/mozilla-central/rev/b24799980a929597dcc553cb0854aa6c960c82b5/devtools/client/netmonitor/test/browser_net_url-preview.js#124-127

I couldn't repro on my machine (win10) using:

$ mach test devtools/client/netmonitor/test/browser_net_url-preview.js --verify --headless

Bomsy, could you see the failure?

Hello everybody,

thanks for all the pointers.
I have been trying to reproduce it with the commands you suggested. I also used the command ./mach mochitest devtools/client/netmonitor/test/browser_net_url-preview.js multiple times before submitting the patch and again this morning, but I can't seem to reproduce the issue (also windows 10).

I can try to set the request as an if condition, so that the related test (same file, lines 129-133) get executed only if the request exists.
Let me know if this is acceptable or if I should proceed in other ways.

Thanks again for your help,
Alessia

Hi Honza,
I tried running on my machine but was not able to reproduce as well
I also tried enabling ac_add_options --enable-debug in my mozconfig that didn't seem to work locally.
I think because of the local-machine perf the 3rd request always comes in on time.

Allesia,
I did a bit more investigation.
We can see from this screenshot taken during the test failure shows there are only 2 requests and you are trying to retrieve the 3rd request
The issue is likely that
https://searchfox.org/mozilla-central/rev/489e82dcc1e5afbe691ff3b1c982382914637e38/devtools/client/netmonitor/test/browser_net_url-preview.js#91 needs to be bumped to 3. i.e

 const netWorkEvent = waitForNetworkEvents(monitor, 3);

waitForNetworksEvents tries to wait for the no of requests that are expected, to be available before the test continues. I think it fails intermittently because your test is later and sometimes the 3rd request comes in late, but this fix guarantees that the request is always there in time.

Thanks

Yes, you should list bugs (their URLs) you've been working on.
Not sure what you mean by "record a new one" (of course you can pick yet another one if you wanted)

Sorry, here is what I mean:
on the Outreachy website I have to record the bugs I have been working on. I was unsure if this counts as a bug on its own since it stems directly from the other patch I submitted (1732305).
Also, the URL to submit is the bug page here on Bugzilla?
Thank you in advance,
Alessia

OK, I see. You should record both bugs.

Correct

The patch landed in nightly and beta is affected.
:alevanni19, is this bug important enough to require an uplift?
If not please set status_beta to wontfix.

For more information, please visit auto_nag documentation.
