  2. Architecture approaches (and case studies) for engineering web apps.
  3. Latest developments in JavaScript and web ecosystem – the cutting edge.
  4. Best practices: debugging and profiling on the web, testing, measuring performance.
  5. JS off the web – conversational UI, raspberry pi, IoT

We are inviting proposals:

  1. Full talks: 40 mins duration
  2. Crisp talk: 20 mins duration
  3. Hands-on workshops of 3 or 6 hour duration
  4. Birds Of Feather (BOF) sessions of 45-60 mins duration

Selection process

Proposals will be filtered and shortlisted by an Editorial Panel.

** Make sure to add links to videos / slide decks when submitting proposals. We will not review proposals without detailed outlines or slide decks and preview videos.**

The first filter for every proposal is whether the technology or solution you are referring to is open source or not. If you are referring to a proprietary technology, consider picking up a sponsored session.

The criteria for selecting proposals, in the order of importance, are:

  1. Key insight or takeaway: what can you share with participants that will help them in their work and in thinking about the problem?
  2. Structure of the talk and flow of content: a detailed outline helps us understand the focus of the talk, and the clarity of your thought process.
  3. Ability to communicate succinctly, and how you engage with the audience. You must submit link to a two-minute preview video explaining what your talk is about, and what is the key takeaway for the audience.

No one submits the perfect proposal in the first instance. We therefore encourage you to:

  1. Submit your proposal early so that we have more time to iterate if the proposal has potential.
  2. Write to us on: jsfoo.editorial@hasgeek.com if you want to discuss an idea for your proposal, and need help / advice on how to structure it.

Our editorial team also helps potential speakers in refining their talk ideas, and rehearsing at least twice - before the main conference - to sharpen the insights presented in the talk.

##Passes and honorarium for speakers:
We pay an honorarium of Rs. 3,000 to each speaker and workshop instructor at the end of their talk/workshop. Confirmed speakers and instructors also get a pass to the conference and networking dinner. We do not provide free passes for speakers’ colleagues and spouses.

##Travel grants for outstation speakers:
Travel grants are available for international speakers who have led/worked on projects that have large-scale adoption. Travel grants are available for domestic speakers (without the criteria mentioned for international speakers).
We evaluate each travel grant application on its merits, giving preference to women, people of non-binary gender, and Africans. If you require a grant, request it when you submit your proposal in the field where you add your location. JSFoo is funded through ticket purchases and sponsorships; travel grant budgets vary.

##Important dates:
JSFoo + Meta Refresh: 26 and 27 October, at the NIMHANS Convention Centre.

End-to-end testing: from rookie to pro

Submitted Jul 21, 2018

You can gain a lot from a stable suite of end-to-end tests, but not a lot of developers know how easy it is to setup these tests. Dive into this crash course on end-to-end testing, you’ll first learn the basics and then some advanced techniques that will have you testing like a pro in no time.

The talk is a walkthrough guide on how to get up and running with end-to-end tests, using WebdriverIO as an example framework for demonstration purposes. Once I’ve gone through the basic setup and some simple examples, I’ll show some advanced techniques for testing some of the trickier aspects of a website.

The talk will involve both slides and (offline) live coding, and will demonstrate how easy it is to get started with end-to-end tests. It is suitable for all audiences that have experience using Javascript, and is applicable to anyone developing a website, regardless of the technologies it is built with.


What is end-to-end testing?

  • Basic explanation
  • Why it is useful
  • Comparison with other types of testing
  • Comparison of libraries (Why WebdriverIO? Instead of nightwatch, casperjs, cypress.io etc...)

Setup a test suite with WebdriverIO

  • Quick configuration and first test with WebdriverIO CLI
  • Examples of what you can achieve out of the box

Integrating webdriverio with other tools

  • Visual regression with screenshot comparisons
  • Mobile testing with Appium
  • Integration with Zalenium
  • Integration with Browserstack and Saucelabs

Advanced techniques

  • Testing a11y
  • Testing console errors
  • Testing video
  • Testing sound
