Visual Regression Testing - How Selenium can help?

In today's software world, web applications need to go though constant change to maintain highest standards of quality of service. With continuous changes, one of the biggest challenges in the testing fraternity is to reduce the effort in regression testing. Often UI testing is cited as an area where automated tools have a limitation.

In this session, will try to cover how using a simple program and using tools like ImageMagick, we can automate visual regression of the site in no time. Also, this means after every change (front-end or feature) if causes any unexpected behavior can be brought to notice immediately. A set of benchmark images of the stable version will be compared against those from the build's latest version and help reduce the extra effort testers spend in testing the UI on different browsers.

    This talk suggests a reframe in how we understand the business value of automated testing. One shift is to see automation as "checking" rather than "testing". Another is the shift from software delivery to service delivery, including fully embracing DevOps. The resulting approach could be called Checking as a Service or CheckOps, and forces us to rethink traditional automation priorities. In this talk, Bret will explain how change in approach has affected teams he's worked with and how you can use it to improve your ability to deliver valued services.

    Have you ever wondered how Selenium works under the covers? Do you get frustrated with locators not locating, pages not loading, or browsers behaving inconsistently from one run to the next? Selenium is an attempt to unify thousands of disparate elements across a wide spectrum of challenges into a single, common interface that works seamlessly with all the major browsers - and yet only a handful of volunteers work to maintain this gigantic effort. If you would like to enhance your own Selenium experience while contributing back to the software that has defined so many of our careers, come to this workshop. In it we'll dissect the different elements of Selenium, dive into its internals, learn how it was built and how to make changes to it, and even write a unit test you can contribute on the same day!

    This small talk is about the intricate fabric of discussion between an interviewer and an interviewee for the post of Automation Engineer.

    The audience would be taken through a maze of silly, run of the mill, subjective, bizarre and occasionally brilliant questions/answers/discussions found in an average interview for Automation Engineer/Selenium Engineer. 

    We'll try to look at the 4 quadrants of the Selenium Interview circle, covering it from the perspectives of :

    1. The Interviewer
    2. The Interviewee
    3. Current Industry state
    4. How can we improve?

    This might seem like a soft, non-technical, not-so-important topic of discussion but we must remember that bad interviews lead to bad candidates lead to bad deliverables. As they say, For want of a nail the battle was lost. 

    And in today's cut-throat world none of us can afford losing a good candidate to a bad interview.

    Lets gather around a fire of questions, on the beach of answers to surgically comprehend the What, How and Why of Selenium Interviews.

    We see two upcoming trends in the world of software delivery.

    1.Docker is becoming a standard for managing infrastructure using containers.

    2.Testing code and its infrastructure starts to grow at scale with more complexity, dependencies and technology diversity.

    A container is an entire portable runtime environment: an application, plus all its dependencies, libraries and other binaries, and configuration files needed to run it, bundled into one package. By containerizing the application platform and its dependencies ,all differences in OS distributions and underlying infrastructure are abstracted away which makes it easy to share and execute anywhere.

    At this talk we will learn how to leverage the container technology to solve the challenges of growing testing infrastructure and continuous delivery with key focus on below items.

    • Basics of the containers technology and specifically it’s application on the test automation. 
    • How Docker can reduce the time of test execution, ease the setup of clean test environments and drastically reduce the differences between the development, acceptance and production environments leading to the higher quality of the released software.
    • Examples to containerize entire testing stack together consisting of major automation tools (selenium, appium, phantomjs), performance tools (jmeter,gatling) with cucumber. 
    • Integrating and managing testing container with other application containers to achieve easily manageable continuous delivery pipeline.
    • Best practices and patterns for docker success.

    Roy Nuriel / Sreevatsa S - From Pyramids to hourglass - New approach and best practices for digital apps testing

    45 Mins
    Talk
    Executive

    One of the first things that you learn when you enter the quality assurance space is the famous triangle braked down to Unit test at the lower, on top of it Acceptance Tests based on API (in some places this layer is integration tests but the idea is the same) and at the top of the Pyramid we have the User Interface (UI) Tests. This Pyramid, in the last two decades was the main principle on how to approach testing activities (mainly automation).

    In the last couple of year we are all taking part in the digital transformation that is taking place all over. Mobile Native applications as well as web applications take part in almost any activity that we are doing during the day, business are building their strategy on this channel and shifting resources and budgets to deliver applications maintained and expend their market share.

    So what changed?

    The users are no longer static, they are interacting with those apps while they are on the train on their way to the office, while waiting for a flight at the airport or drinking coffee while waiting for their next meeting – those “interactions” are done most of the time while they are on the go working with mobile device. In addition the application take advantage of the sensors that those devices provide in order to provide better user experience. The environment where our end users use our application has significant impact on the functionality and performance of our application which at the end of the day we call quality.

    During the last year we developed a new approach for digital application testing – The “Hourglass” – This new approach expend the known Pyramid and update it to the digital era – The client side is richer and contains many components that impact the quality of application. It redefine the definition of coverage. At the top of the pyramid we add 2 additional triangles (the gives the hourglass shape) – The first one is devices – what devices should we test, how we should approach the changes that happens in the devise market. The second is the environment, the places that our end users will use and interact with the application. We leverage the automation investment and get the real digital coverage which will help to reach high quality applications.

    Building a Test Automation Framework is easy - there are so many resources / guides / blogs / etc. available to help you get started and help solve the issues you get along the journey.

    Teams already building 1000s of tests of various types - UI, web service-based, integration, unit, etc. is a proof of that.

    However, building a "good" Test Automation Framework is not very easy. There are a lot of principles and practices you need to use, in the right context, with a good set of skills required to make the Test Automation Framework maintainable, scalable and reusable.

    In this talk, we will focus on one of the critical aspects and patterns in building the Test Automation framework - Test Data!

    We will look at different data patterns as options and techniques how to create, manage, use, reuse Test Data in a way to keep the tests running in an reliable and deterministic way. We will also discuss what questions to ask, what things to think about in selecting your approach for Test Data!

    This discussion will be applicable for any type of Test Automation (web / mobile / desktop), but, we will focus primarily on UI automation frameworks, ex. using Selenium.

    Michal Vanek / Filip Braun - Breaking down the barriers: Testing desktop apps with Selenium

    45 Mins
    Talk
    Intermediate

    Selenium was born for web-application testing. But have you ever thought it could be a great tool for testing Windows desktop apps too?

    Today, more and more desktop apps use a web-like approach to implement their UI. The methods vary from basic HTMLayout environment to complex designs in CEF (Chromium Embedded Framework). However traditional GUI automation tools seem to be a step behind or ignoring the trend completely. This situation calls for finding new ways of testing.

    In our talk we shall introduce to you a new way of utilizing Selenium for automated testing of desktop applications. No matter whether the HTML UI content is completely offline or loaded and updated dynamically, Selenium is able to access and navigate it just like in a web page. We’ll also show you how to build a small framework around it and plug it into your Continuous Integration process. All of this will be demonstrated using a real-life instance of Avast Antivirus for Windows.

    Sarvesh Shrivastava - Functional and Security Testing - An amalgamated automation approach

    45 Mins
    Demonstration
    Intermediate

    With increasing cyber threats & online attacks, an unavoidable situation for continuous security testing has emerged. Making sure all vulnerabilities are unleashed regularly is highly significant.

    The paper hence proposes a solution where automated security testing could be achieved in conjunction with functional testing carried out using selenium API.

    It introduces a framework that caters to automated security testing along with functional which could provide an integrated testing elucidation.

    The paper, takes in these two premises to offer a solution where functional automation testers can now take on security testing. I propose a framework where automated security testing could be achieved in conjunction with functional testing using existing selenium API scripts.

    The framework covers the top vulnerabilities and provides intuitive results that help a non-security tester interpret and act on the output. At the very core of this framework is the open source tool, OWASP ZAP, which is easy to use and integrates well with Selenium automation frameworks.

    I bring in hands on project experience having implemented this framework for clients, who have been able to get the value of functional and security testing using the same set of scripts – it is this experience I would like to share with the SeleniumConf2016 audience, to help groom functional testers into security testing, with minimal cost and time, also enabling security testing to be performed every time functional automation is taken up.

    Parashuram - Reusing Selenium tests for catching Performance Regressions

    90 Mins
    Demonstration
    Beginner

    Almost all the tests we write today are geared towards verifying the functional correctness of products. Selenium gives us a great way to ensure that our web applications and browser behave correctly and our tests usually do an excellent job running through the happy path.

    Most successful websites or hybrid mobile applications are not just functionally correct, but also have a very smooth performance and user experience. Performance, for many, is now a feature. In this talk, we will look at ways to re-use our selenium test cases to also catch any performance regressions. We will measure key performance indicators like frame rates and memory usage as the selenium scripts navigate and perform actions on the website. We will look at logging all these metrics into a dashboard, and integrating this with a continuous integration system like Jenkis or Team City. Finally, we will also look at how such a system can catch any code change that is responsible for making the website slower than a threshold we set.

     

    We will look at how we could use existing testing frameworks like Protractor or Jest to add performance metrics. We will extend our test matrix to cover desktop browsers, browsers on popular mobile platforms and even hybrid apps like Apache Cordova, Ionic or Phonegap.

     

     

    If Performance is a feature, let us test it like we test features !!
