Quarterly Goals[edit]

Program 1: Outcome 5: Milestone 1: Develop and migrate to a JavaScript-based browser testing stack[edit]

Due: End of this quarter
What: Specific improvements to the now canonical framework, see: task T182421, notably:
Upgrade webdriverIO to version 4.9
Investigate replacing nodemw with mwbot
Video recording for Selenium tests in Node.js
Task: task T182421

Priority: high

  • T179188 Video recording for Selenium tests in Node.js - in progress - will do this week
  • T180144 Upgrade WebdriverIO to 4.12.0 - resolved
  • T181284 Replace nodemw with mwbot - in progress - almost done, updating documentation
    • T190426 Refactor AdvancedSearch browser tests which use nodemw module - in progress - helping AdvancedSearch team

Priority: normal

  • T164721 Run Selenium tests in CI for extensions - not started - CI changing
    • T180125 Refactor mediawiki-core-qunit-selenium-jessie Jenkins job so qunit/karma and webdriverio are invoked via npm script - not started
    • T180482 Create mediawiki-core-qunit-selenium-composer-jessie - not started
  • T182692 Document differences between Ruby and Node.js Selenium frameworks - not started - not hard to do, will do this week
  • T185011 Create selenium-MediaWiki-jessie daily Jenkins job - in progress
  • T188740 Retrospective for T139740 Port Selenium tests from Ruby to Node.js - resolved

Priority: low

  • T182412 Investigate if WebdriverIO `sync: false` would be useful to us and document how to use it - in progress - it could be useful for some tests, documentation pending, will do this week
  • T182691 Selenium tests should be easier to run - in progress - blocked by upstream bug
  • T183160 Sample code in Node.js for repositories that still have Selenium+Ruby tests - not started
  • T183162 Patches in Gerrit deleting Selenium+Ruby tests for repositories that still have them - not started
  • T185094 Update page object pattern in Selenium tests - in progress - done, but probably will not be implemented, discussion with upstream to revert to previous recommendation is probably the best thing to do
  • T187859 Move one Selenium tests from mediawiki/core to mediawiki/skins/Vector - in progress - blocked on understanding how it breaks Minerva
  • T188742 Should selenium-EXTENSION-jessie run for all repositores with Selenium tests? - not started - have to contact repository owners

Program 1: Outcome 5: Objective 1: Maintain existing shared Continuous Integration infrastructure[edit]

Goals
Draft requirements for a Kubernetes based solution for CI - task T183513
Migrate MediaWiki PHPUnit tests to Shipyard (docker-based CI) (~40% of Nodepool usage) - task T183512
Will be worked on after the long tail task T187797
Unify production and CI docker image build process - task T177276
Yes Done 01/15

Program 3: Outcome 2: Objective 2: Define and implement a process to regularly address technical debt across the Foundation[edit]

Due: End of quarter
task T174095

worked on technical debt avoidance framework.

Program 3: Outcome 2: Objective 3: Promote and surface important technical debt topics at large gatherings of Wikimedia developers (e.g., DevSummit and Hackathon(s))[edit]

Due: End of next quarter
task T174096

No activity

Program 6: Outcome 2: Objective 2: Set up a continuous integration and deployment pipeline[edit]

Due: End of this quarter
Keyword: SSD
phab project: https://phabricator.wikimedia.org/project/view/2453/
Goal:
Verify basic functionality of 'production' deployment and image (initially targeting mathoid):
Functional PoC within integration in the deployment-pipeline
Deploy to isolated k8s

thcipriani update[edit]

This is a severely long bit of notes about what I did last week so that you all can pick up where I left off...hopefully

  • We are sooo close to getting the PoC working, I was trying to build an image that worked that I could then puppetize
  • I ended up blocked on a few things, some of which were resolved over the weekend.

Creating a new minikube agent 1. Create a new machine in horizon named like: integration-slave-k8s-10XX 2. ssh to machine (have to wait a bit, puppet needs to run there) 3. Fix weird self hosted puppet issues (see https://www.mediawiki.org/wiki/Continuous_integration/Docker#Jenkins_Agent_Creation )

* sudo rm -fR /var/lib/puppet/ssl
 * sudo mkdir -p /var/lib/puppet/client/ssl/certs
 * sudo puppet agent -tv
 * sudo cp /var/lib/puppet/ssl/certs/ca.pem /var/lib/puppet/client/ssl/certs
 * sudo puppet agent -tv

4. Apply the role role::ci::slave::labs::docker to the instance via horizon 5. sudo puppet agent -tv (this was failing last week see https://phabricator.wikimedia.org/T190584 ) 6. Setup minikube:

sudo apt-get install -y helm minikube kubernetes-client export MINIKUBE_WANTUPDATENOTIFICATION=false export MINIKUBE_WANTREPORTERRORPROMPT=false export MINIKUBE_HOME=$HOME export CHANGE_MINIKUBE_NONE_USER=true mkdir $HOME/.kube || true touch $HOME/.kube/config export KUBECONFIG=$HOME/.kube/config

sudo -E minikube start --vm-driver none --bootstrapper=localkube

7. Clone all necessary repos git clone https://gerrit.wikimedia.org/r/operations/deployment-charts git clone https://gerrit.wikimedia.org/r/mediawiki/services/mathoid

8. Build mathoid image cd mathoid blubber dist/pipeline/blubber.yaml production | docker build -t mathoid -f - .

9. Setup helm/tiller This is where I got stuck :( See: https://phabricator.wikimedia.org/T190589

10. helm install && helm test? Maybe? Didn't get this far :(
