Top 5 Code Coverage Tools in DevOps

Many organizations are introducing test automation only to discover it is more difficult than they anticipated. The fact is that good test automation requires good coding practices. Good test automation requires good design. To do anything else will lead to spaghetti code that is hard to maintain or update. If you’re new to coding or new to automation, it is difficult to know where to begin. Join Cheezy as he describes and demonstrates lessons he has learned while helping numerous organizations adopt test automation. Cheezy shows the patterns he uses to keep automation code simple and clean, and demonstrates techniques you can use to make your automation code more maintainable. Finally, Cheezy writes code (without a net) to implement these patterns, taking them from theory to implementation.

Testing JSX components can be quite tricky, especially if they include GraphQL queries. What if I told you it is possible to both test your GraphQL queries and mutations, while also testing the way they interact with your JSX components? This talk will show how you can push your testing principles to the next level by writing unit tests and integration tests that will use the type system of GraphQL. Not only can you drastically increase your test coverage after this talk, you’ll know for sure that your data is flowing correctly through your application.

During one of my personal projects I decided to study the internals of Android and the potential of altering the Dalvik VM (e.g. Xposed framework and Cydia) and application behaviour. Not going into detail about runtime hooking of constructors and classes like these two tools provide, I also explored the possibility of reverse engineering and modifying existing applications. In the web you can find multiple tutorials on Android reverse engineering of applications but not many that do it with real applications that are often subject to obfuscation or with complex execution flows. So in order to learn I decided to pick a common application such as Skype and do the following: decompile it study contents and completely remove some functionality (e.g. ads) change some resources (not described in presentation bellow) recompile, sign and install. Used tools include : apktool – for (de)compiling android applications jarsigner – for signing android applications xposed – for intercepting runtime execution flow (will make public in future) The following presentation describes the steps taken in order to completely remove the ads from skype. This includes any computation or data plan usage the ads consume. Please note the disclaimer of the presentation as this information is for educational purposes only.

Have you heard of TDD? Are you interested or familiar with this practice but have never been able to understand it? In this presentation we will see the benefits of Test-Driven Development (TDD), understand how it works and what the benefits are of using it. We will see in a more detailed approach this way of developing software, where our software is always built guided by tests. We will go over some history about TDD, which is the main process we must follow when we work with this mechanic and the rules that surround it. We will also list the main advantages and disadvantages that most developers who practice TDD find and whether the arguments in favour add up to more than those that subtract. Finally, we will review some good habits and practices when applying TDD and see how to do it step by step with an example of "live" coding session with Java. At the end of the session, we hope that you will have a wider understanding of what TDD is, what advantages it brings, why it is interesting to master it and also that you will take with you some tricks and good practices to be able to apply them in your day-to-day life when writing code 

Full webinar recording: https://youtu.be/4FIvObHfCMQ -- Listen to Gil Tayar's webinar on the new Applitools SDKs for Storybook and CypressIO, which enable developers to test and validate the visual appearance of your application across all responsive platforms. ======== Developers want their tests to run fast. In an increasingly agile world, waiting 10+ minutes for test results is a huge no-no. A new generation of browser automation tools recognize that need-for-speed and enable frontend developers to quickly automate their browser tests. But those tests also need to check the application’s visual elements. Does the login page look OK? Does it look good in Firefox? What about mobile browsers, in 768px width? And does it still look good in 455px with a device pixel ratio of 2? To check the visual quality of your application, across all browsers and in all those responsive widths, would necessitate a humongous grid of browsers, and an unreasonable amount of time. Far more than the 2-5 minutes usually available for a developer’s tests. Applitools’ new Storybook and Cypress SDKs enable you to do just that: write a set of tests that run through your pages and components, and have the pages and components render in Applitools’ cloud, in parallel, on a large set of browsers and widths, and return the result in less than a minute. Watch Gil Tayar's presentation, as he discusses the new generation of visual testing tools. Tools that move the burden of the visual work to cloud, and enable you to check what was till now impossible to check locally: the visual appearance of your application across all responsive platforms.

Taking lessons from the classic writings on Software Testing, we'll walk through what are industry tried and true approaches for developing a robust and effective test suite. Many of the Testing philosophies and strategies today have their origins as far back as the 60's, and really got their legs during the advent of "Extreme Programming" and other early "Agile" methodologies from the 1990s. In this talk we'll take many of these tried and true test strategies and show how one would apply them in a real way to an Ember project.

Do you find yourself with limited influence over what gets shipped on products you test? Is your report card on product quality often ignored? Do you think you can contribute more? Join Gerard Meszaros as he describes ways to transition from approaching quality with brute force testing to an enlightened and strategic perspective that will have real impact on product quality. Instead of criticizing the product, become an integral part of the development process and learn how you can help define what should be built. Gerard explores design for testability concepts and describes key testability requirements that will afford better, more efficient testing. He explains test design techniques that describe software functionality in layers of plain language tests. Gerard shows how a collaborative approach for building the right product results in much better outcomes from both quality and schedule perspectives. Stop rushing through multiple test-and-fix cycles that result in a less than quality product. Be part of the solution!

In her book Agile Testing: A Practical Guide for Testers and Agile Teams, Janet Gregory recommends using the automation pyramid as a model for test coverage. In the pyramid model, most automated tests are unit tests written and maintained by the programmers,and tests that execute below the user interface—API-level tests that can be developed and maintained collaboratively by programmers and testers. However, as agile becomes mainstream, some circumstances may challenge this model. Many applications are transferring logic back to the client side by using programming languages such as JavaScript. Legacy systems, using languages such as COBOL, don’t have access to unit testing frameworks. Janet shows how to adapt the model to your needs and addresses some of these automation issues. During the session, delegates are encouraged to share their challenges and success stories.

Our industry has a problem: We are not lacking software methodologies, programming languages, tools or frameworks but we need great software engineers. Great software engineer teams build quality-in and deliver great software on a regular basis. The technical excellence of those engineers will help you escape the "Waterfall sandwich" and make your organization a little more agile, from the inception of an idea till they go live. I will talk about my experiences from the last 15 years, including small software delivery teams until big financial institutions. Why would a company like to be "agile"? How can a company achieve that? How can you achieve Technical Excellence in your software teams? What developer skills are more important than languages, methods or frameworks? This will be an interactive session with a Q&A at the end.

Data spaces in distributed environments should be allowed to evolve in agile ways providing data space owners with large flexibility about which data they store. Agility and heterogeneity, however, jeopardize data exchanges because representations may build on varying ontologies and data consumers may not rely on the semantic correctness of their queries in the context of semantically heterogeneous, evolving data spaces. Graph data spaces are one example of a powerful model for representing and querying data whose semantics may change over time. To assert and enforce conditions on individual graph data spaces, shape languages (e.g SHACL) have been developed. We investigate the question of how querying and programming can be guarded by reasoning over SHACL constraints in a distributed setting and we sketch a picture of how a future landscape based on semantically heterogeneous data spaces might look like.
