Commitment to Open Source
HasGeek believes in open source as the binding force of our community. If you are describing a codebase for developers to work with, we’d like it to be available under a permissive open source license. If your software is commercially licensed or available under a combination of commercial and restrictive open source licenses (such as the various forms of the GPL), please consider picking up a sponsorship. We recognize that there are valid reasons for commercial licensing, but ask that you support us in return for giving you an audience. Your session will be marked on the schedule as a sponsored session.
If you are interested in conducting a hands-on session on any of the topics falling under the themes described above, please submit a proposal under the workshops section. We also need you to tell us about your past experience in teaching and/or conducting workshops.
If you are interested in doing an unconference during the breakout sessions, propose a topic which will be of interest to the community.
Deadline for submitting proposals: 31 July 2015
Conference dates: 18-19 September
Workshops: 15, 16, 17 and 20 September
Automating cross browser + platform perceptual difference testing
You have a webapp. That’s your business. So you need it to be just as you designed it at all times. You may have your unit tests written for the JS, but what about how it actually looks like? One fine day you change some line in CSS and inadvertently make your blue buttons go green. How do you ensure that your platform looks exactly like it should across a myriad of browsers and platform combinations? And the best part, how do you keep this automated?
Razorpay is a payments startup. We have a JS powered Checkout page that is embedded in a merchant’s website. Since this is where the transactions begin for an end user, we just cannot have it broken at any time. So we developed a tool called Bozo in node.js for automated visual regression tests. This is apart from the whole bunch of unit tests we have.
Bozo checks for visual regressions on a page across multiple browser + platform combinations. Using a webhook after every successful deploy, it takes the screenshots of the page using the Browserstack APIs. It then compares each screenshot on a platform browser combo, with the last deploy’s screenshot for this combo. It then reports back the number of matches and no-matches.
It is similar to the work that Google has done on dpxdt.
The tool will be open sourced before the talk on Razorpay’s GitHub.
