Most Interesting Bugs

Written by Etonkovidova on Thu, May 27, 4:20 PM.

What makes a bug interesting? Any bug, by definition, has an element of a surprise (otherwise, it wouldn't be a bug). But not all bugs are equal in their ability to be surprising. Some bugs do stand out, presenting two essential elements of a surprise - unexpectedness and/or unusual manifestation. Based on my own classification criteria, I define a bug to be the most interesting if it is either (or both)
(1) difficult to find
(2) has a quite unexpected (mostly disruptive) impact

Improvements to Email QA

Written by jbolorinos-ctr on May 7 2021, 4:50 PM.

When running QA on emails, the most important things to check are the dynamic content populating correctly for different user types, and ensuring there are no layout issues. Especially in an increasingly mobile world, it's important to review how an email will be displayed on a large variety of devices at once.


Breakpoint at BrowserStack conferences (2020-2021) - Part 2 Focus on Exploratory testing

Written by Etonkovidova on Apr 30 2021, 6:08 PM.

Since I was impressed with the depth of presentations at Breakpoint conference (at Browserstack) in July 2021 - see my post Breakpoint at BrowserStack conferences (2020-2021) - reflections and thoughts: Part 1 - Focus on Automation, it was really exciting to see that the next conference (March 2021) would be focusing on the intriguing topic of exploratory testing. The the presentations titles (here is the list of all presentations) looked equally exciting, for example

  • "Manual testing is not dead...just the definition"
  • "Whole team holistic quality"
  • "Contemporary Exploratory Testing"
  • "Building a testing culture"

Exempla Docent - Testing instrumentation on Special:Homepage (QA perspective)

Written by Etonkovidova on Dec 31 2020, 3:47 AM.

Two previous posts - Exempla Docent Part 1 and Part 2 outlined QA approach to testing functionality of the Suggested edits (SE) module on Special:Homepage. Part 1 explored testing ORES model-articletopic logic implementation and Part 2 described testing user workflows.


Struggle, the road to growth

Written by Harriet on Dec 24 2020, 8:47 AM.

It has been more than 3 weeks into my Outreachy internship with Wikimedia foundations. The internship started well and the project that I'm working on is about evaluating Microsoft playwright as a possible replacement to the current automation testing framework being used. Week one was mostly about setting up the Wikimedia core by forking and cloning the Wikimedia core repository from Github. In order to simplify continuous integration, we are using Github as our code hosting platform to evaluate playwright instead of using Gerrit. The setup involved the following steps;

  • Forking the Wikimedia repository
  • Cloning the repository, setting up and running it on my local machine
  • Connecting my forked with upstream
  • Configuring CI.

To dream a dream. My Outreachy Journey

Written by Harriet on Dec 1 2020, 1:45 PM.

The year 2020 has been a year of massive change in the entire world, there are mixed feelings of loss, confusion among others, but all in all, there is always hope that keeps us moving forward. I must say that being accepted as an Outreachy intern has been that ray of light at the end of the tunnel that I needed to end the year and begin the new year. Outreachy is a paid, remote internship program with the goal to support people from groups underrepresented in tech. Starting my career in the field of software engineering has been a journey of hard work, persistence, and seizing every opportunity since where I come from such opportunities are rare and the support for women's engagement in technology is quite low.


Exempla Docent - testing UI for Suggested edits module

Written by Etonkovidova on Nov 30 2020, 4:31 AM.

In Part 1 of Exempla Docent for QA practices, some approaches to testing ORES model articletopic were explored. This post, as Part 2, will present an overview on testing Suggested edits module (SE) - the UI that presents the ORES articletopic logic to users (more info on Newcomers tasks on Special:Homepage).


Engineering Productivity Virtual Offsite October 2020

Written by zeljkofilipin on Nov 27 2020, 3:53 PM.

October 26-29 2020 was my team's second virtual offsite. We've had many offsites, but the first virtual one was in May 2020. The structure of this offsite was similar to the one in May. About four hours of sessions every day, from Monday to Thursday.


Spin up a basic local Phabricator instance with Docker

If you want to experiment with Phabricator and/or the Phabricator APIs, it can be convenient to have a local instance to play with.

ORES provides machine learning as a service for Wikimedia projects. The ORES model articletopic was used for the Growth team project - Suggested edits for newcomers on Special: Homepage.


Visual Studio Code + Neovim

Written by zeljkofilipin on Oct 7 2020, 2:48 PM.

I've started using Vim in 2014. I've read a few books, wrote a few articles and gave a few talks on Vim. I really like editing text with Vim, but I was never happy with it's file management, extensions, things like that.


Google Summer of Code, June-August 2020

June and July were pretty busy. I was on vacation the majority of August. Interns and other mentors were busy even then. For more introduction, read my post Blog Post: Google Summer of Code, February-May 2020.

In February 2020 I've noticed an e-mail that Wikimedia is participating in Google-Summer-of-Code. Unfortunately, I've ignored the e-mail and soon forgot about it.


Fanboying Cypress

Written by Soham on Jul 7 2020, 11:50 AM.

Software development is pretty agile in its nature in that things normally tend to move pretty quickly. However, the faster you move, the more things break. As a codebase grows in size, its pieces become more and more complex, with every line adding a potential bug. In Wikimedia Foundation, we keep a handle on this through rigorous amounts of testing. Manual testing requires a lot of effort especially when you have a large core repository with a plethora of plugins and extensions that need to be tested. One of the hot frameworks on the scene is Cypress, a complete end to end testing solution.
