Firefox Automation report – Q1 2015

As you may have noticed I was not able to come up with status reports of the Firefox Automation team during the whole last quarter. I feel sad about it, but there was simply no time to keep up with those blog posts. Even now I’m not sure how often I will be able to blog. So maybe I will aim to do it at least once a quarter or if possible once a month.

You may ask how it comes? The answer is simple. Our team faced some changes and finally a massive loss of core members. Which means from the former 6 people only myself are remaining. Since end of February all 5 former team members from Softvision are no longer participating in any of the maintained projects. Thanks to all of them for the great help over all the last months and years! But every project we own is now on my own shoulders. And this is kinda hell of work with downsides like not being able to do as many reviews as I want for side projects. One positive thing at least was that I got pulled back into the A-Team at the same time. With that move I’m once more closer again to all the people who care about the basics of all test infrastructure at Mozilla. I feel back home.

So what have I done the whole last quarter… First, it was always the ongoing daily work for maintaining our Mozmill CI system. This was usually a job for a dedicated person all the last months. The amount of work can sometimes eat up a whole day. Especially if several regressions have been found or incompatible changes in Firefox have been landed. Seeing my deliverables for Q1 it was clear that we have to cut down the time to spent on those failures. As result we started to partially skip tests which were failing. There was no time to get any of those fixed. Happily the latest version of Mozmill is still working kinda nicely so no other work had to be dedicated for this project.

Most of my time during the last quarter I actually had to spent on Marionette, especially building up wrapper scripts for being able to use Marionette as test framework for Firefox Desktop. This was a kinda large change for us but totally important in terms of maintenance burden and sustainability. The code base of Mozmill is kinda outdated and features like Electrolysis (e10s) will totally break it. Given that a rewrite of the test framework is too cost-intensive the decision has been made to transition our Mozmill tests over to Marionette. Side-effect was that a lot of missing features had to be implemented in Marionette to bring it at a level as what Mozmill offers. Thanks for the amazing work goes to Andrew Halberstadt, David Burns, Jonathan Griffin, and especially Chris Manchester.

For the new UI driven tests for Firefox Desktop we created the firefox-ui-tests repository at Github. We decided on that name to make it clear to which product the tests belong to, and also to get rid of any relationship to the underling test framework name. This repository contains the harness extensions around Marionette, a separate puppeteer library for back-end and UI modules, and last but not least the tests themselves. As goal for Q1 we had to get the basics working including the full set of remote security tests, and most important the update tests. A lot of help on the security tests we got from Barbara Miller our intern from December to March. She did great amount of work here, and also assisted other community members in getting their code done. Finally we got all the security tests converted.

My own focus beside the harness pieces were the update tests. Given the complete refactoring of those Mozmill tests we were able to easily port them over to Marionette. We tried to keep the class structure as is, and only did enhancements where necessary. Here Bob Silverberg helped with two big chunks of work which I’m gladly thankful about! Thanks a lot! With all modules in-place I finally converted the update tests and got them running for each version of Firefox down to 38.0, which will be the next ESR release and kinda important to be tested with Marionette. For stability and ease of contribution we added support for Travis CI to our new repository. It helps us a lot with reviews of patches from community members, and they also can see immediately if changes they have done are working as expected.

The next big chunk of work will be to get those tests running in Mozmill CI (to be renamed) and the test reporting to use Treeherder. Also we want to get our update tests for Firefox releases executed by the RelEng system, to further reduce the amount of time for signoffs from QE. About this work I will talk more in my next blog post. So please stay tuned.

Meeting Details

If you are interested in further details and discussions you might also want to have a look at the meeting agendas, the video recordings, and notes from the Firefox Automation meetings. Please note that since end of February we no longer host a meeting due to the low attendance and other meetings like the A-team ones, where I have to report my status.

Firefox Automation report – week 51/52 2014

In this post you can find an overview about the work happened in the Firefox Automation team during week 51 and 52 of 2014. I’m sorry for this very late post but changes to our team, which I will get to in my next upcoming post, caught me up with lots of more work and didn’t give me the time for writing status reports.

Highlights

Henrik started work towards a Mozmill 2.1 release. Therefore he had to upgrade a couple of mozbase packages first to get latest Mozmill code on master working again. Once done the patch for handling parent sections in manifest files finally landed, which was originally written by Andrei Eftimie and was sitting around for a while. That addition allows us to use mozhttpd for serving test data via a local HTTP server. Last but not least another important feature went in, which let us better handle application disconnects. There are still some more bugs to fix before we can actually release version 2.1 of Mozmill.

Given that we only have the capacity to fix the most important issues for the Mozmill test framework, Henrik started to mass close existing bugs for Mozmill. So only a hand-full of bugs will remain open. If there is something important you want to see fixed, we would encourage you to start working on the appropriate bug.

For Mozmill CI we got the new Ubuntu 14.10 boxes up and running in our staging environment. Once we can be sure they are stable enough, they will also be enabled in production.

Firefox Automation report – week 43/44 2014

In this post you can find an overview about the work happened in the Firefox Automation team during week 43 and 44.

Highlights

In preparation for the QA-wide demonstration of Mozmill-CI, Henrik reorganized our documentation to allow everyone a simple local setup of the tool. Along that we did the remaining deployment of latest code to our production instance.

Henrik also worked on the upgrade of Jenkins to latest LTS version 1.565.3, and we were able to push this upgrade to our staging instance for observation. Further he got the Pulse Guardian support implemented.

Mozmill 2.0.9 and Mozmill-Automation 2.0.9 have been released, and if you are curious what is included you want to check this post.

One of our major goals over the next 2 quarters is to replace Mozmill as test framework for our functional tests for Firefox with Marionette. Together with the A-Team Henrik got started on the initial work, which is currently covered in the firefox-greenlight-tests repository. More to come later…

Beside all that work we have to say good bye to one of our SoftVision team members.October the 29th was the last day for Daniel on the project. So thank’s for all your work!

Firefox Automation report – week 41/42 2014

In this post you can find an overview about the work happened in the Firefox Automation team during week 41 and 42.

With the beginning of October we also have some minor changes in responsibilities of tasks. While our team members from SoftVision mainly care about any kind of Mozmill tests related requests and related CI failures, Henrik is doing all the rest including the framework and the maintenance of Mozmill CI.

Highlights

With the support for all locales testing in Mozmill-CI for any Firefox beta and final release, Andreea finished her blacklist patch. With that we can easily mark locales not to be tested, and get rid of the long white-list entries.

We spun up our first OS X 10.10 machine in our staging environment of Mozmill CI for testing the new OS version. We hit a couple of issues, especially some incompatibilities with mozrunner, which need to be fixed first before we can get started in running our tests on 10.10.

In the second week of October Teodor Druta joined the Softvision team, and he will assist all the others with working on Mozmill tests.

But we also had to fight a lot with Flash crashes on our testing machines. So we have seen about 23 crashes on Windows machines per day. And that all with the regular release version of Flash, which we re-installed because of a crash we have seen before was fixed. But the healthy period did resist long, and we had to revert back to the debug version without the protect mode. Lets see for how long we have to keep the debug version active.

Firefox Automation report – week 39/40 2014

In this post you can find an overview about the work happened in the Firefox Automation team during week 39 and 40.

Highlights

One of our goals for last quarter was to get locale testing enabled in Mozmill-CI for each and every supported locale of Firefox beta and release builds. So Cosmin investigated the timing and other possible side-effects, which could happen when you test about 90 locales across all platforms! The biggest change we had to do was for the retention policy of logs from executed builds due to disk space issues. Here we not only delete the logs after a maximum amount of builds, but also after 3 full days now. That gives us enough time for investigation of test failures. Once that was done we were able to enable the remaining 60 locales. For details of all the changes necessary, you can have a look at the mozmill-ci pushlog.

During those two weeks Henrik spent his time on finalizing the Mozmill update tests to support the new signed builds on OS X. Once that was done he also released the new mozmill-automation 2.0.8.1 package.

Firefox Automation report – week 37/38 2014

In this post you can find an overview about the work happened in the Firefox Automation team during week 37 and 38.

Highlights

After 7 months without a new release we finally were able to release mozdownload 1.12 with a couple of helpful enhancements and fixes.

We released Mozmill 2.0.7 and mozmill-automation 2.0.7 mainly for adding support of the v2 signed Firefox application bundles on OS X. Sadly we quickly had to follow-up with an appropriate 2.0.8 release for both tools, because a let change in the JS Engine caused a complete bustage of Mozmill. More details can be found in my appropriate blog post.

We were even able to finally release Memchaser 0.6, which is fixing a couple of outstanding bugs and brought in the first changes to fully support Australis.

One of our goals was to get the failure rate of Mozmill tests for release and beta candidate builds under 5%. To calculate that Cosmin wrote a little script, which pulls the test report data for a specific build from out dashboard and outputs the failure rate per executed testrun. We were totally happy to see that the failure rate for all Mozmill tests was around 0.027%!

During the merge process for the Firefox 32 release Andrei has seen some test inconsistencies between our named branches in the Mozmill-Tests repository. Some changes were never backported, and only present on the default branch for a very long time. He fixed that and also updated our documentation for branch merges

Something else worth for highlighting is also bug 1046645. Here our Mozmill tests found a case when Firefox does not correctly show the SSL status of a website if you navigate quickly enough. The fix for this regression caused by about:newtab made it even into the release notes

Last but not least Andreea started planning our Automation Training day for Q3. So she wrote a blog post about this event on QMO.

Firefox Automation report – week 35/36 2014

In this post you can find an overview about the work happened in the Firefox Automation team during week 35 and 36.

Highlights

Due to a lot of Mozmill test failures related to add-on installation and search, we moved from the addons-dev.allizom.org website to the staging website located at addons.allizom.org. Since then we experiencing way lesser test failures, which are most likely network related.

In order to keep up with all test failures, and requests for new tests we started our Bug triage meeting on a weekly basis on Friday. For details we have created an etherpad.

If you are interested in helping us with Mozmill tests, you can now find a list of mentored and good first bugs on the bugsahoy web page.

Because of the app bundle changes on OS X, which were necessary due to the v2 signing requirements, we had to fix and enhance a couple of our automation tools. Henrik updated mozversion, mozmill, and mozmill-automation. We were close to releasing Mozmill 2.0.7.

Firefox Automation report – week 33/34 2014

In this post you can find an overview about the work happened in the Firefox Automation team during week 33 and 34.

Highlights

To make sure that our weekly meetings will be more visible to our community, we got them added to the community calendar. If you are interested in what’s going on for Firefox Automation you are welcome to join our Monday’s team meeting.

In regards of the Mozmill project, Henrik landed his patch, which makes Mozmill more descriptive in terms of unexpected application shutdowns. Especially in the past weeks we have seen that Firefox does not restart as expected, but simply quits. There is bug 1057246 filed for the underlying problem. So with the patch landed, Mozmill will log that correctly in the results. Beside that we can also better see when crashes or a not by Mozmill triggered quit happens.

For Mozmill CI we landed a couple of enhancements and fixes. The most important ones were indeed the addition of 20 new locales for testing beta and release builds of Firefox across supported platforms. That means we cover 30 of about 95 active locales now. To cover them all, a good amount of follow-up work is still necessary. Immediately we stopped to run add-on tests for all branches except Nightly builds to save more time on our machines.

Henrik also continued on PuppetAgain integration for our staging and production CI systems. One of the blockers was the missing proxy support, but with the landing of the patch on bug 1050268 all proxy related work should have been done now.

Also on the continuous integration for TPS tests we made progress. The implementation got that far for Coversheet that we made the Jenkins branch the active master. There are still issues to implement or get fixed before the Jenkins driven CI can replace the old hand-made one.

Firefox Automation report – week 31/32 2014

In this post you can find an overview about the work happened in the Firefox Automation team during week 31 and 32. It’s a bit lesser than usual, mainly because many of us were on vacation.

Highlights

The biggest improvement as came in during week 32 were the fixes for the TPS tests. Cosmin spent a bit of time on investigating the remaining underlying issues, and got them fixed. Since then we have a constant green testrun, which is fantastic.

While development for the new TPS continuous integration system continued, we were blocked for a couple of days by the outage of restmail.net due to a domain move. After the DNS entries got fixed, everything was working fine again for Jenkins and Mozilla Pulse based TPS tests.

For Mozmill CI we agreed on that the Endurance tests we run across all branches are not that useful, but only take a lot of time to execute – about 2h per testrun! The most impact also regarding of new features landed will be for Nightly. So Henrik came up with a patch to only let those tests run for en-US Nightly builds.

Memchaser 0.6 has been released

The Firefox Automation team would like to announce the release of memchaser 0.6. After nearly a year of no real feature updates, but also some weeks of not being able to run Memchaser in Firefox Aurora (34.0a2) at all (due to a regression), we decided to release the current state of development as a public release. We are aware that we still do not fully support the default Australis theme since Firefox 29.0, but that’s an issue, which takes some more time to finish up.
