We have a current implementation of the ping server for testing that was written for a custom test harness. We are looking to migrate that ping server to work with the marionette harness. Original Ping Server: https://dxr.mozilla.org/mozilla-central/source/testing/marionette/harness/session/runner/ping_server.py Destination: https://dxr.mozilla.org/mozilla-central/source/testing/marionette/harness/marionette/runner/httpd.py There will need to be some work done to make sure that this ping server conforms to what is implemented in Marionette using the wptserve package.

When I mentioned wptserve I didn't say that you have to rewrite the server! What you need are actually your own setup request handlers, so that you can listen for any ping request.

I uploaded the patch so you could let me know if you understand why the self.marionette_weakref() call is saying throwing an unresolved reference error. I made sure to call super() but perhaps you can spot where I went wrong.

Good to see that you got rid of this extra server instance which drops the complexity a lot.

And I noticed that only offering the `baseurl` in the Marionette object is reducing our capabilities a lot. It means no test could setup its own handlers or tweak the server for specific behavior eg. slow responses. I would suggest that you file a new bug for Marionette which will implement such a change. Please don't do it here in this patch. It might mean a bit of refactoring, where we would have to get feedback from Andreas and David first.

This patch is an updated version of the previous. It makes the changes you were suggesting. You will see that there is an httpd server that we spin up manually. That is only a workaround until the blocker bug is resolved.

I think I covered most of everything you had asked in the previous feedback session. Please let me know if this looks better.

Preferences enabled during test: telemetry_prefs = { 'toolkit.telemetry.enabled': True, 'toolkit.telemetry.send.overrideOfficialCheck': True, 'toolkit.telemetry.server': self.ping_url, 'toolkit.telemetry.initDelay': '1', 'datareporting.healthreport.uploadEnabled': True, 'datareporting.policy.dataSubmissionEnabled': False, 'datareporting.policy.dataSubmissionPolicyBypassNotification': True, 'toolkit.telemetry.log.level': 0, 'toolkit.telemetry.log.dump': True } I made sure to set MOZ_TELEMETRY_REPORTING=1 in a mozconfig file before building. I have also attached the gecko logs from marionette.

Found the issue. For some reason, data submission was disabled. Got that error fixed and pings are working now.

I assume this needs an update of the patch. Just asking before I start a review in the middle of a next update.
Yes. I that will need to be updated.
Comment on attachment 8848582 [details] Bug 1301781 - Add test harness for telemetry tests https://reviewboard.mozilla.org/r/121492/#review126474 The current implementation looks way cleaner now. So it shouldn't take that long anymore until we can call this done. In the following you can find a couple of review comments. ::: commit-message-34585:1 (Diff revision 3) > +Bug 1301781 - Submitted patch for converting ping server to marionette witha small test to ensure that the server works. Please shorten the decription to something like: `Add test harness for telemetry tests`. Then add a more details description after an empty line what's actually contained in this patch, and which explains all that good enough. ::: toolkit/components/telemetry/tests/marionette/harness/__init__.py:3 (Diff revision 3) > +# This Source Code Form is subject to the terms of the Mozilla Public > +# License, v. 2.0.

I would still propose that you add a subfolder here like `tests/marionette/harness/telemetry_harness`. It's a better structure for your Python package. Only `setup.py` and `requirements.txt` should remain at the current location. Btw. the latter file I cannot find in this patch. ::: toolkit/components/telemetry/tests/marionette/harness/setup.py:18 (Diff revision 3) > + > +def read(*parts): > + with open(os.path.join(THIS_DIR, *parts)) as f: > + return f.read() > + > +setup(name='telemetry-tests', This package is the harness and not the tests. ::: toolkit/components/telemetry/tests/marionette/harness/testcase.py:18 (Diff revision 3) > +from marionette_harness.runner import httpd > + > + > +here = os.path.abspath(os.path.dirname(__file__)) > +doc_root = os.path.join(os.path.dirname(here), "www") > +temp_dir = os.path.join(os.path.dirname(here), "temp") For temporary directories do not use a folder inside the tree.

If that is the case please rename the property appropriately. ::: toolkit/components/telemetry/tests/marionette/harness/testcase.py:48 (Diff revision 3) > + 'toolkit.telemetry.log.level': 0, > + 'toolkit.telemetry.log.dump': True > + } > + > + # Firefox will be forced to restart with the prefs enforced. > + self.marionette.enforce_gecko_prefs(telemetry_prefs) Given that those prefs (beside toolkit.telemetry.server) will apply to all telemetry tests you should better move everything to the harness itself and add your own default prefs there. This wouldn't require an extra restart of Firefox and saves lots of time. See `firefox_ui_harness/runners/update.py`. ::: toolkit/components/telemetry/tests/marionette/harness/testcase.py:50 (Diff revision 3) > + } > + > + # Firefox will be forced to restart with the prefs enforced. > + self.marionette.enforce_gecko_prefs(telemetry_prefs) > + if not os.path.exists(temp_dir): > + os.makedirs(temp_dir) See above.

I would separate those into eg. `tests/marionette/tests/unit/`.

I just realized that the change in the implementation of the server parsing requests made it so we don't even need a temp folder anymore. Thanks for catching that.

If that is the case please rename the property appropriately. Can you clarify on this? The tests do not have to add a separate suffix. Perhaps ping_server_url would be more appropriate?

The tests do not have to add a separate suffix. Perhaps ping_server_url would be more appropriate? This is just about the variable name, yes. So how can ping URLs look like? I ask because of your definition of `/pings.*`.

So how can ping URLs look like? I ask because of your definition of `/pings.*`. Ah, that's a good catch. The url will be something like "localhost:57658/pings" So I am removing the ".*" at the end.

The ping server url being changed will need to trigger a restart anyways since that is only queried when firefox starts. So we may as well set the rest of the prefs here.

So we may as well set the rest of the prefs here. Also, I didn't create a harness class for these tests per your instructions a while back. I only created a runtests.py just running the cli command.

I only created a runtests.py just running the cli command. Well, it was just an idea of improvements for test runtimes. Each additional restart makes your tests slower. But it's something which could be improved later. Regarding the ping url and the HTTP server, if you don't need a fresh instance for each test, you could still run it via the harness. But again, not a blocker for this landing.
Comment on attachment 8848582 [details] Bug 1301781 - Add test harness for telemetry tests https://reviewboard.mozilla.org/r/121492/#review127112 r=me with the following issues fixed. Please keep in mind that I will be out the next days. So for remaining questions please contact Maja or Andreas in #ateam. ::: commit-message-34585:5 (Diff revisions 3 - 4) > -Bug 1301781 - Submitted patch for converting ping server to marionette witha small test to ensure that the server works. > +Bug 1301781 - Add test harness for telemetry tests > + > +Added requirements.txt > +Adjusted file structure > +Made edits to test and variables Those items are not pretty helpful. It would be better to have complete sentences which explain what this harness is, what it is used for, and such. ::: toolkit/components/telemetry/tests/marionette/harness/requirements.txt:3 (Diff revision 4) > +marionette-harness > +firefox-puppeteer > +marionette-driver You might want to use fixed versions for marionette related packages. See our firefox-ui tests harness, or the external media tests. nit: please fix the ordering of entries. ::: toolkit/components/telemetry/tests/marionette/harness/telemetry_harness/testcase.py:27 (Diff revision 4) > + > + def setUp(self, *args, **kwargs): > + super(TelemetryTestCase, self).setUp() > + > + # Start and configure server > + self.httpd = httpd.FixtureServer(doc_root) The constructor if `FixtureServer` checks if the `doc_root` is a directory. Given that `www` is not part of your patch it will fail. Also I would propose to put the `www` folder beside the `telemetry_harness` folder, and not within it. ::: toolkit/components/telemetry/tests/marionette/harness/telemetry_harness/testcase.py:59 (Diff revision 4) > + self.ping_list.append(json_data) > + return 200 > + > + > +def unpack(headers, data): > + post_data = data You can remove this extra variable. It has not purpose. Something what I missed last time is that you are also using the headers. :/ So passing the request object itself into this method, might still make sense. But feel free to revert it or not. ::: toolkit/components/telemetry/tests/marionette/tests/unit/test_ping_server_received_ping.py:1 (Diff revision 4) > +# This Source Code Form is subject to the terms of the Mozilla Public You should also add a manifest file to this folder, which contains this single test for now.

Comment on attachment 8852671 [details] Bug 1301781 - Add test harness for telemetry tests https://reviewboard.mozilla.org/r/124854/#review127626 I’m not a topic expert on this, so I have just made some general comments about style. Please take my review with a grain of salt. Generally this patch looks clean and good. I’m not a huge fan of the unittest-based testing style, so part of me wish we had a better story to ensure new Marionette tests would use something else. ::: toolkit/components/telemetry/tests/marionette/harness/telemetry_harness/runtests.py:9 (Diff revision 2) > +def cli(): > + mn_cli(testcase_class=TelemetryTestCase) I don’t understand the purpose of this function. If you need a runtests.py file to kick off the tests, it should be made executable (`chmod u+x runtests.py`). However, did you consider integrating this with mach? ::: toolkit/components/telemetry/tests/marionette/harness/telemetry_harness/testcase.py:27 (Diff revision 2) > + self.httpd = httpd.FixtureServer(doc_root) > + self.httpd.start() > + ping_route = [("POST", re.compile('/pings'), self.pings)] > + self.httpd.routes.extend(ping_route) It may work fine to add routes after the FixtureServer has been started, but I would flip these around to be on the safe side, and do self.httpd.start() after you have extended the routes. ::: toolkit/components/telemetry/tests/marionette/harness/telemetry_harness/testcase.py:59 (Diff revision 2) > + return zlib.decompress(data, zlib.MAX_WBITS | 16) \ > + if "Content-Encoding" in headers \ > + and headers["Content-Encoding"] == "gzip" else data Because the statement goes over three lines, I think this is more readable: > if headers.get("Content-Encoding") == "gzip": > return zlib.decompress(data, zlib.MAX_WBITS | 16) > else: > return data You can likely also use dict.get("foo") which returns None if key "foo" isn’t found. ::: toolkit/components/telemetry/tests/marionette/tests/unit/test_ping_server_received_ping.py:17 (Diff revision 2) > + > + def test_ping_server_received_ping(self): > + > + data = {'sender': 'John', 'receiver': 'Joe', 'message': 'We did it!'} > + headers = {'Content-type': 'application/json', 'Accept': 'text/plain'} > + r = requests.post(self.ping_server_url, data=json.dumps(data), headers=headers) ‘r’ is a keyword in pdb. Consider using a name that doesn’t conflict when using a debugger.
