As more and more companies are moving to the Cloud, they want their latest, greatest software features to be available to their users as quickly as they are built. However there are several issues blocking them from moving ahead.

One key issue is the massive amount of time it takes for someone to certify that the new feature is indeed working as expected and also to assure that the rest of the features will continuing to work. In spite of this long waiting cycle, we still cannot assure that our software will not have any issues. In fact, many times our assumptions about the user's needs or behavior might itself be wrong. But this long testing cycle only helps us validate that our assumptions works as assumed.

How can we break out of this rut & get thin slices of our features in front of our users to validate our assumptions early?

Most software organizations today suffer from what I call, the "Inverted Testing Pyramid" problem. They spend maximum time and effort manually checking software. Some invest in automation, but mostly building slow, complex, fragile end-to-end GUI test. Very little effort is spent on building a solid foundation of unit & acceptance tests.

This over-investment in end-to-end tests is a slippery slope. Once you start on this path, you end up investing even more time & effort on testing which gives you diminishing returns.

In this session Naresh Jain will explain the key misconceptions that has lead to the inverted testing pyramid approach being massively adopted, main drawbacks of this approach and how to turn your organization around to get the right testing pyramid.

On Reddit, IAmA stands for "I am a" and AMA stands for "ask me anything".

In an IAmA post, a person will post what they are, and other people will ask the original poster some questions to gain insights about the experience the person has had.
 
Ex: I'm Jeff Patton, creator of Story Mapping, Ask Me Anything... OR I'm Diana Larsen, co-creator of the Fluency Model and co-author of Agile Retrospectives, Ask Me Anything...

We plan to take this concept and apply it to the Agile context. We've few luminaries at the conference and we plan to do an live interview with them using this format.

Test Driving a jQuery Plugin
Naresh Jain
Naresh Jain

Over the past decade, eXtreme Programming practices like Test-Driven Development (TDD), Behavior Driven Developer (BDD), Refactoring and Continuous Integration have fundamentally changed software development processes and inherently how engineers work. Practitioners claim that it has helped them significantly improve their development speed, design quality and responsiveness to changing requirements. Software professionals across the board, from Internet startups to medical device companies to space research organizations, today have embraced these practices. But can these practices be applied to front-end development? Especially jQuery plugin development?

This demo will show how we can test drive a jQuery plugin with the help of various patterns, strategies, tools and techniques. Participants will understand how they can apply this approach for testing any jQuery code.

"To know, is good. To live, is better. To be, that is perfect." - The Mother

During the Agile adoption, its a common complain that many team in many organizations get caught up in the ceremonies or mechanics of Agile and fail to understand/appreciate the true value and spirit of Agile. And because of this, the original intent of the Agile movement itself is lost. This is a serious issue!

This workshop will highlight, a well-proven approach to transformation (not adoption) and show the distinct steps in this journey that an individual or a collective goes through when learning anything new. Activities, serving as examples, in the workshop, will focus to show the journey - that is, how to begin with rituals, then gradually move to practices, arriving at principles and eventually internalizing the values. Witnessing this gradual process of transformation will help participants discover for themselves their current progression. We hope this will serve as a guiding light during their Agile journey.

Finally, we will leave the participants to ponder upon and discover for themselves their ideals in life and work as this is not only applicable to software development, but also to any discipline where humans are involved, including life itself.

Adaptive Change Cycle AND The Decline of Agile
Naresh Jain
Naresh Jain

Why do we see new process or methodology or movement every 10 years or so in the software industry? And why don't successful companies ride on their success forever? Naresh Jain uses the Adaptive Change Cycle (ACC) to explain the rationale behind it. Once you understand ACC, this talk will help you understand how to prepare yourself and your organisation to quickly move through the 4 stages of ACC: reorganise, exploit, conserve and release to constantly keep innovating. If you feel agile methods are stagnating and looking for what to expect next, this talk might give you some ideas.

Sell Before you Build (MVP Hacks)
Naresh Jain
Naresh Jain

Before you write any code, make sure you have a failing test." This was a revolutionary idea, when it was first pitched in the late 90’s. Many successful entrepreneurs have been practicing a similar approach - "Before you build a product/service, make sure you have paying customers." In this talk, Naresh Jain shares his approach of finding effective MVPs to validate his Educational Product and why Agile Methods simply fail to do so. If you are interested in finding out how to maximise your validated learning for minimum investment, then this session is for you. Recently Naresh's article on this topic was published by InfoQ.

Implementing Agile Engineering Practices in Legacy Codebases
Prasad Kunte
Prasad Kunte
Naresh Jain

Afraid of legacy code? Don't be!!!

Most successful product companies are confronted with the problem of legacy code.

What is a legacy code?

  • A code which is in production for several years.
  • A super-complex, hard to understand code base, written by different set of developers. 
  • Outdated Technology stack.

But the most hurting reality is:

Lack of confidence in the code due to zero or poor test coverage.

Due to this reality, developers are often scared to touch it. They have very little confidence that "their code change wouldn't break the existing application in production."

Recently at IDeaS, we came across such situation, where we needed to enhance one of our products containing legacy code. We started looking into the code and soon figured out that it was developed in 2007, hardly ever touched (& still working in production :)). The original team, which has worked on this product, could not be traced anymore.

As this product has expanded to attract new customers, we had to change it significantly in order to support new customer's specifications. We had to make sure that the product was backward compatible and supported the earlier specifications, while we enhance the new specification.

One simple option was to COPY PASTE every single method which needs to be modified and use an if-statement to decide which method to call. This certainly seems like an easy method, since the chances of breaking existing code is very little. 

Today we all know this is a BAD option!!!

Instead, our team decided to refactor the existing code to support plug-and-play approach for different specification. But before we started refactoring code, we had to build a safety net of tests around the existing code.

How do we put the safety net? Ideal way would be to implement the Test Pyramid first. But, that would have taken significant time to be ready with the pyramid before we start touching the legacy code. And obvious, we would have missed the business goals.

What do we do?

Instead of building the entire test pyramid, we decided to attack different layers of the test pyramid, one at a time. Along the way, we followed the following approach:

  1. Re-structuring the Project code-base
  2. Establishing a baseline database: After taking a dump from the production database, we cleared out surplus data from the DB and setup a seed database with automed scripts
  3. Creating/fixing the build script 
    1. Setting up an auto DB deploy tool and integrating it with build scripts
  4. Set up basic CI pipeline
  5. Write a few work-flow tests to capture the system's flow from user's point of view
    1. Find the inception point in the code from where we can exercise the code
    2. Restify the application at the inception point (one service at a time)
    3. Setup authorization for production and test environment
    4. Build minimal test-data set for different environment 
    5. Create a few work-flow tests via the inception point (Test itself should not be coupled with the underlying database or implementation level components)
  6. Write business logic acceptance test to capture various complicated business rules
  7. Test drive the new enhancement or bug fixes
  8. Every time we touch legacy code, refactor the code and improve test coverage at unit level

This really helped us test driven the new code and implement all the layers of the test pyramid.

If you've a similar situation, join us, as we share our experience on how to confront legacy code.

Death of Inspection: Reincarnation of the Testing Community
Sachin Natu
Sachin Natu
Naresh Jain

Adopting agile development practices and continuous delivery is becoming a norm in the software industry. Time to market and frequent releases have drastically reduced time available for regression testing. Inspection is considered wasteful. Faster feedback cycles during development is crucial. These have created lot of challenges for testing community, which traditionally relies on manual testing assisted by UI based test automation.

This is an experience report of transforming testing practices across organization, which decided to embrace Agile. Today our testers are not trying to find defects, instead they collaborate with product management and developers to prevent them in the first place. In fact, during the appraisal process, the defects found by them is ignored, instead we focus on how much time they are able to dedicate to collaboration and exploratory testing. The boundaries between developers and testers have faded away and today quality is whole team's responsibility.

We started with less than 20% of our testers with automation skills (mostly UI automation) and rest of them relying on manual testing. However, today, all our testers practice BDD. They have picked up Java & Groovy programming skills. They are able to contribute Workflow tests, Integration tests and Business Logic Acceptance Tests. Early collaboration and pairing is the norm. By the time developers are done with their tasks, all checks are already automated and hence we are able to deploy software every fortnight to production.

Are your testers finding it hard to make this transition to an Agile mindset? This session will give you some concrete ideas based on our transition at IDeaS.

Techniques to Speed Up your Build Pipeline for Faster Feedback.
Ashish Parkhi

Naresh Jain

I would like to share my experience and journey on how we brought down our Jenkins build pipeline time down from over 90 minutes to under 12 minutes. In the process, I would share specific techniques which helped and also some, which logically made sense, but actually did not help. If your team is trying to optimize their build times, then this session might give you some ideas on how to approach the problem.

Development Impact - For one of our build job, below graph shows how the number of builds in a day have increased over a period of time as the build time has reduced. Frequency of code check-in has increased; Wait time has reduced; failed test case faster to isolate and fix.

Business Impact - More builds leading to quicker feedback and faster story acceptance and less story spill over.

Techniques for Effectively Slicing User Stories
Naresh Jain
Naresh Jain

In order to achieve my goals, as a buyer of your product, I want awesome feature.

AT: make sure your users stories don't get in the way.

Users Stories, the tool teams use to break big ideas into small demonstrable deliverable, are easy to describe and challenging to write effectively. In this hands-on workshop you'll learn how to write great user stories that adhere to the INVEST principle. We'll learn various techniques to slice your stories using the vertical-slicing approach. We will discuss what elements should be included in the stories, what criteria you should keep in mind while slicing stories; why the size of your user story is important and how to make them smaller and efficient.

Building Up the Community
Scott González
Scott González

Over the past seven years, jQuery UI has identified and solved many common problems for web developers. Often times, the problems don't apply just to users of jQuery UI, or even jQuery Core. In these cases, we try to solve the problem in the best way for the largest audience, rather than creating an isolated solution within jQuery UI. We're able to do this by working with the community and bringing together various groups to collaborate on solutions. In this talk, I'll discuss how this concept is at the heart of the jQuery Foundation and explain some of the projects that have been born out of jQuery UI.

How BDD can save agile
Aslak Hellesøy
Aslak Hellesøy

As lead developer of Cucumber and author of The Cucumber Book, Aslak gets asked to consult with organisations who want to introduce Behaviour-Driven Development (BDD). Time after time, he meets teams who are trapped doing half-arsed agile. They do the easy, obvious, visible agile practices, and none of the powerful, hard-to-master, hard-to-see ones.

When these teams ask for help learning BDD, we get a chance to remind them how important conversations and collaboration are in software development. We teach them to write tests before they write code, as a way to explore and discover the hidden details of a requirement just before they dive in and start building it. This talk will make you wince with recognition, laugh with despair, and finally inspire you with stories of teams that have finally, after years of flaccid scrumming, discovered the true collaborative heart of agile software development. You’ll see patterns you recognise from your own teams, and gain insights about how to fix them.

Gamifying Agile Adoption - An Experiment
Ashish Parkhi
Ashish Parkhi
Naresh Jain

While having a chat with Naresh Jain, he suggested me to go through the Ted Talk – “Gaming can make a better world” by Jane McGonigal. I found the title very weird and was wondering how is that possible? After going through the talk though, I was amazed. I started wondering if I can use the gamification technique in Agile Adoption, in our Products, in Performance Management Systems, in Employee Engagement Programs?

Dhaval Dalal introduced me to Prof. Kevin Werbach’s definition of Gamification – “The use of game elements and game design techniques in non-game contexts.

For our 4th ShipIt Day, organized on 25th/26th Sept 2014 at IDeaS, I decided to explore the idea of using game elements and game design techniques in the context of Agile Adoption. The idea was to create a gaming system which will automatically collect data, i.e. without explicit user intervention,  from multiple sources like Jenkins, Rally and manually from individuals and offer Star’s for positive behavior and deduct Star’s otherwise.

The aim was to help the team get continuous visual feedback on how they are doing, adopt agile practices, visualize sense of accountability, visualize sense of achievement, drive positive behavior, create healthy competition, create a culture of appreciation, help performance tracking and create transparency.

Over the last decade, eXtreme Programming practices like User Stories, Evolutionary Design, Test-Driven Development (TDD), Behavior Driven Developer (BDD), Refactoring, Continuous Integration and Automation have fundamentally changed software development processes and inherently how engineers work.

Having experienced various benefits from XP practices on our J2EE stack, our team started to apply these practices to extract, transform, and load (ETL) and Data Analytics side of our product. Unfortunately, there is very little guidance available in this context, esp. for the SAS Platform. Right from finding the unit testing framework to structuring the code to designing our modules and setting up a Continuous Integration builds, our team had to figure out everything, the hard way.

Join us to understand the challenges we faced during this process and how we resolved these challenges.

The Art of SQL Database Refactoring

Prafulla Girgaonkar
Naresh Jain

"We've tested this feature thoroughly and it worked really well. But for some weird reason, it's really slow in production today...must be a network issue...or may be the server is having a bad day..."

Do you often hear these kinds of comments in your development team? Let us guess, your application is very data-centric and churns big blocks of data on every user request. And under the hood, your application is most probably heavily dependent on long/complex queries with joins, temp-tables, case-statements, nested queries, etc.

These SQL queries probably started-out very simple. But as your requirements evolved, iteration after iterations, the queries also grew in complexity. And most often, even if you test-drove your newer stories, the performance of these complex queries is not evident until you run them in production. 

Given that our requirements will evolve and so will our database, how do you deal with the above problems?

There are TWO essential parts to evolutionary database design:

  1. The art of refactoring your SQL queries.
  2. Figuring out the right balance of what processing is done in SQL on the DB sides and what is done on your service side in your App/Web Server.

Join us as we take a tour of how we refactored our complex, non-performant queries and overall DB without hurting our time-to-market.

A contrarian view to building data interactive front-ends
Ritvvij Parrikh
Ritvvij Parrikh

We live in world of “big data”. However, the front-end for the “big data” age is the browser which cannot hold more than 1-5 MB of data at any given moment of time. The problem becomes more aggravated in mobiles where the bandwidth is even lower. How to build user interfaces that are data heavy and interactive in nature?

Why choose jQuery over AngularJS?
Adriaan de Jonge
Adriaan de Jonge

If you follow the JavaScript community, it seems like the whole world is switching over to AngularJS. Using AngularJS you can achieve more interactive single page interfaces with less code. AngularJS also downsides, like the complexity of the framework. When searching for alternatives the fast-paced world of JavaScript frameworks, did you consider good old jQuery? This talk points out why you should!

Prabhat Kumar
Prabhat Kumar

Advances in the biological research area like genomics and proteomics resulting proliferation of massive complex data. These data are very complex in nature require better understanding, to know about the relationship between these. That's why it may have laid the technological foundation for biological data visualization by using graph theory approach.

To transform these raw data into meaningful representation, is required. This demonstration provides the power and flexibility of modern JavaScript like jQuery, d3, backbone and require libraries to present the best-of-breed data-driven visualizations with a real-world case study.

Ionic Framework - power of angular meets smartness of phonegap
Rajat Talwar
Rajat Talwar

You have got a great idea for a mobile app and you want to get started. You prototype wireframes, hire(or become) ios developer, hire(or become) android developer , maintain 2 codebases , 2 separate test suites.. - Not anymore.

What if you could start with just wireframes  and build them into your polished MVP just being on one language,one codebase,one repository,and one test suite. Hello Ionic!.

Ionicframework combines the power of angularjs ,smartness of phonegap/cordova to produce native like hybrid html mobile apps.

While most UI frameworks are just javascript/css, ionic goes a step further to combine UI libraries with phonegap plugins to provide a continuous experience while coding hybrid apps.Its also one of the very few frameworks which has UI transitions/graphics very closely matching with the native UI elements/transitions.

What you'll learn 

  • How to get started with writing native like apps using ionicframework.
  • Theming your app using sass.
  • Writing unit-tests for ionic apps using karma-jasmine.
  • How to distribute your apps for beta testing among your friends/folks/testers without publishing to appstores.

JSON-LD - Making every object matter in Semantic Web
Janardan Revuru
Janardan Revuru

Over the period, web has transformed itself from 'Document oriented' (web pages) to 'Data oriented' (sections, objects) to now the direction is for it to be Semantic. As conceived by the visionary (Tim-Berners Lee), Web 3.0 is the Semantic Web. And, Linked-Data is the first step towards it.

HTML5 has 'semantic' tags that make web content more meaningful. The introduction of microdata is another step towards connecting the data and better structure for search engines to consume. How do you as web developer consume existing vast linked data and how do you produce your data in a way that is effective. Let it be just enhancing the user experience by using the vast linked data sources or you gearing up for better Search Engine Optimization (SEO), it is a must you understand LINKED-DATA.

Going framework-less with jQuery and FRP (RxJS)
Charanjit Singh
Charanjit Singh

Functional Reactive Programming is a slightly different take towards asynchronous programming which helps creating simple and powerful software with good architecture. FRP reduces the complexity of a asynchronous code by providing a unifying concept to cover most things asynchronous, and the result is a easy to build and easy to maintain architecture. Reactive programming is a powerful concept, Meteor is a living proof of that. FRP is another, more advanced (imho) flavour of reactive programming.

This session we'll create a moderately complex app called YARR (Yet Another RSS Reader) which is a decentralised social network of blogs, using jQuery and RxJS without any front-end isomorphic javascript framework. We're going framework-less for this session so we could concentrate only on FRP concepts which might be little hard to grasp for those who do little Functional Programming (sadly, most of Js devs). This session will demonstrate how FRP leads to a saner architecture for apps without relying on a framework for forcing your hand to do so.
