BDD (Behavior-driven development) is a software development process focusing on active collaboration, which illustrates and automates the requirements using key examples of the problem domain. In BDD the formalized examples use a natural language-based DSL driven by the Given/When/Then keywords. At the same time, property-based testing (PBT) uses abstract (mathematical) formulas to declare expectations for the output values given some constraints on the input. The PBT tools try to disproof that the application fulfills these requirements by taking samples from the valid input value space. The experience shows that for understanding and properly implementing the requirements, the team has to understand the requirements as a set of abstract rules, where collecting key examples can help a lot. BDD is strong at managing and automating these key examples and PBT is strong at defining and automating the rules, so the question should arise: can these two methods somehow support each-other? Can we increase the value of BDD by formalizing and testing the rules? Can we increase the value of PBT by a better communication of the rules and constraints we have? This session shows an experiment of combining BDD and PBT. It provides examples of how the specification could look like in this combined world and what it could be used for. And there is a working, open-source prototype too!

This talk is about creating Node.js interfaces for native libraries written in C or C++. It starts with various situations in which you need to build native addons and the common problems in doing that. I'll discuss the reference provided by the new N-API (Node-API) that helps mantainers to support a wide variety of Node.js releases without needing recompilation or abstraction layers. With all these tools and knowledge I'll show you how to build some addons from scratch and how to convert existing addons using the new N-API. The last part is related to future developments about addons.

Creating an all-purpose REST API for Cloud services using OSGi and Sling - C ...

mfrancis

OSGi Community Event 2014 Abstract: Let's say you need to provide an internet service to your users. Chances are that your service should be available via REST. Let's say your service should both provide data to users as well as accept data posted by users, and possibly some logic. Now let's assume your service turns out to become incredibly popular, with lots and lots of users. Sounds like you need Sling and OSGi in the cloud. In this talk Carsten and David will go through the OSGi and Sling architecture to achieve this. The talk outlines how the OSGi Cloud Ecosystems RFC is used in combination with Apache jclouds to achieve vendor independence. It also discusses how automatic scaling depending on measured load is achieved to ensure responsiveness. The resulting system is a dynamic cloud application handling any REST API, which can scale up and down depending on the need. Speaker Bios: David Bosschaert David Bosschaert works for Adobe Research and Development. He spends the much of his time on technology relating to OSGi in Apache and other open source projects. He is also co-chair of the OSGi Enterprise Expert Group and an active participant in the OSGi Cloud efforts. Before joining Adobe, David worked for Red Hat/JBoss and IONA Technologies in Dublin, Ireland. Carsten Ziegeler Carsten Ziegeler is senior developer at Adobe Research Switzerland and spends most of his time on architectural and infrastructure topics. Working for over 25 years in open source projects, Carsten is a member of the Apache Software Foundation and heavily participates in several Apache communities including Sling, Felix and ACE. He is a frequent speaker on technology and open source conferences and participates in the OSGi Core Platform and Enterprise expert groups.

Abstract If you have ever done or tried to do behavior driven development, you know that finding the right scenarios (ie. tests) and writing the Gherkin feature files with the Given/When/Then steps is not so easy. Many teams leave this task entirely for the developers. Others try to use the sprint planning meeting to discuss the exact phrasing. None of these are really perfect. Regarding my experience, for having good scenarios, you have to have a good sprint planning. In this session I am going to talk about what makes a sprint planning good and how you can facilitate your sprint planning meeting in a way that it helps finding the right examples. You will hear about Specification by Examples, the "Three Amigos", example mapping, really good acceptance criteria and also about team motivation, but more importantly you will hear about how to use them efficiently in practice.

BDD is a method that focuses on defining the requirements based on the expected behavior; DDD is a method that uses a ubiquitous language all across the solution; UX helps design user interactions based on user behavior… and Selenium WebDriver (or similar) is a tool that is mostly used to ignore all these and automate the app using clicks on HTML elements… In this session you will explore options how to improve testing efficiency by looking at UI automation from a different angle by analyzing and understanding the UI concepts used in the application, matching them to domain model elements and build an automation solution that focuses on these.

With modern software development moving at a rapid pace, automation engineers may find it difficult to keep up with frequent changes. Incorporating parts of the testing process into everyone's workflow, this creates the potential for automated testing to mirror software delivery. Description: With modern software development moving at a rapid pace, automation engineers may find it difficult to keep up with frequent changes. But if parts of the testing process are incorporated into everyone's workflow, this creates the potential for automated testing to mirror software delivery. My goal is to make software testing more accessible to entire product and engineering teams by providing familiar tools that allow individuals to easily contribute to the automation process. For this talk, I will explore how we can meet developers halfway by using the javascript-based testing framework WebdriverIO, demonstrate how product managers can create living documentation and test cases using Cucumber, and talk about sharing page objects and testing libraries across multiple services using NPM.

Gáspár Nagy

Abstract: Behavior driven development (BDD) is an agile method that (among others) puts the ideas of agile testing into practice. BDD emphasizes collaboration between testers, developers and the business stakeholders and help preventing bugs by introducing testers and testing concept into the specification phase. This is all fine when you start with a new, green field project. But what about those old legacy applications that have no proper automated test coverage and even if there are automated tests no one is dare to touch them? Is it possible to introduce BDD for these projects? What are the different strategies, collaboration and testing patterns that can be followed? This session gives a brief overview about what BDD is today and addresses these questions. The code examples use .NET and SpecFlow, but can be easily adapted to any other platform too.

BDD Scenarios in a Testing & Traceability Strategy (Webinar 19/02/2021)

Gáspár Nagy

We are inviting you to join our free webinar to see a case study of a real project developed with Behaviour Driven Development (BDD). Our product, "SpecSync for Azure DevOps" has been developed with BDD. The functionalities are specified as BDD scenarios that can be verified as automated tests. But BDD scenarios alone would not be enough for us to meet our quality expectations, so there are other tests and quality considerations as well -- all these fit into our agile testing and traceability strategy. In this webinar Gaspar Nagy gives you a walkthrough of the quality considerations and tests of the product by focusing on the following questions: • What kind of tests are needed? How to decide what is the right way to specify and test a concrete function? • What kind of feedback can we get from the different tests and how? Do they form a test automation pyramid? • How are the requirements expressed in BDD scenarios and how are they connected to the other development artifacts? • BDD, tests automation and continuous integration tips & tricks The webinar focuses on the general testing and automation challenges, so people with or without coding skills are both welcome. At the end of the webinar there will be a Q&A, so you can also ask your own questions. The webinar recording will be made available for everyone who registered.

Rspec and Capybara Intro Tutorial at RailsConf 2013

Brian Sam-Bodden

Behavior-Driven Development and Acceptance Testing are heavily intertwined and in many aspects are one and the same. Both focus on starting at the outer layers of your application by concentrating on what matter to users; behavior. In this session/workshop we'll talk about how testing can be used both for specifying your application yet to be develop expected behavior and as accurate, running documentation that can be used to validate your stakeholder's acceptance criteria. We'll talk about the different types of testing and do a few hands-on exercises to flesh out a Rails application with RSpec and Capybara.

Integrating Existing C++ Libraries into PySpark with Esther Kundin

Databricks

Bloomberg’s Machine Learning/Text Analysis team has developed many machine learning libraries for fast real-time sentiment analysis of incoming news stories. These models were developed using smaller training sets, implemented in C++ for minimal latency, and are currently running in production. To facilitate backtesting our production models across our full data set, we needed to be able to parallelize our workloads, while using the actual production code. We also wanted to integrate the C++ code with PySpark and use it to run our models. In this talk, I will discuss some of the challenges we faced, decisions we made, and other options when dealing with integrating existing C++ code into a Spark system. The techniques we developed have been used successfully by our team multiple times and I am sure others will benefit from the gotchas that we were able to identify.

Approaches to debugging mixed-language HPC apps

Rogue Wave Software

The HPC community is embracing the advantages of mixed-language development environments, presenting challenges for debugging and testing when application execution and data flow cross languages. How can we take advantage of the unique features offered by different languages while minimizing the impact on bug reproduction, root-cause analysis, and solution? This presentation walks through the current mixed-language HPC landscape to describe the problems with testing these types of applications and best-practice solutions using TotalView for HPC. You will learn how these architectures make it easy to “steer” computation between modules of different languages, to accelerate prototyping and development, and how advanced testing techniques provide visibility into the call stack and data for efficient debugging.

BDD API Tests with Gherkin and Behat

Mark Niebergall

_Given_ the prominence of API-first development _when_ developing web applications, projects _then_ need to be tested beyond unit and functional tests. Authoring tests using the Gherkin with Behat provides a way to achieve BDD with APIs. We'll dive right into writing Gherkin, how to create your own test scenarios in Gherkin, and how to hook those tests up with custom PHP test methods. See tests in action with live coding and live demos, including writing new custom tests. Leave excited to produce fully-tested APIs!

Application Programming Interfaces allow developers to leverage existing program code in an effort to build additional functionality, automate processes or present existing functionality in a different format. APIs exist for many of Hyperion products; however, clear examples of how to use them are not always easy to find nor are applications for the API readily available. Proper application of the APIs for HFM, Workspace, FDM, Smartview and Shared Services can simplify the daily routines of end users and administrators. This session will provide a high level overview of how each of the APIs work. Additionally, real-world examples for each API will be provided. Fully working code will be available for download from the ODTUG 12 site which attendees can use in their own environments.

Tree in the Forest - Managing Details in BDD Scenarios (live2test 2024)

Gáspár Nagy

Scenarios are the central artifact of the Behaviour Driven Development (BDD) process. Although many teams use scenarios and tools like Cucumber or SpecFlow to automate them, in many cases their scenarios contain a lot of details, particularly test data, and therefore they become too complicated to support collaboration with the business. The "essential" principle of scenario writing (scenario formulation) states that only those details should be included in the scenario that are relevant for the outcome. This talk provides help for those who struggle implementing this principle or would be interested to learn how you can create brief and maintainable scenarios.

Gáspár Nagy

A teszt automatizálási piramist Mike Cohn vezette több évvel ezelőtt. Bár sokan hallottak már róla, mégis kevesen vannak akiknek az eredeti formájában alkalmazni is tudják. Ennek egyik oka az lehet, hogy a piramis segít leképezni a teszteket az őket megvalósító technológiára (unit, integrációs, UI), de abban, hogy mire szolgálnak ezek a tesztek (tesztelési célok) nem adnak segítséget. A tesztelési jéghegy (testing iceberg) ezt az aspektust próbálja meg megjeleníteni a piramisban. Az előadásban a tesztelési jéghegy ötletét és részleteit vizsgáljuk meg. Megnézzük, hogy a "víz alatti" tesztek hogy tudják támogatni a jéghegy csúcsán álló, az üzleti követelményekre fokuszáló teszteket. Azt is megnézzük, hogy hogyan lehet a teszteket a piramis szintjei között mozgatni és végül, egy-két ötletet adnunk arra, hogy hogyan lehet a teszt automatizálási piramis hasznunkra a saját projektjeinkben.

Continuous Behavior - BDD in Continuous Delivery (CoDers Who Test, Gothenburg...

Gáspár Nagy

Abstract: This session is about my experience with BDD in a Continuous Delivery model. Many teams use Behavior Driven Development (BDD) for automated UI testing. Although UI testing might be an important element of your verification pipeline, it is slow, brittle and costly. But in the era of modern software development we would like to have fast feedback and quick reactions. A continuous delivery / deployment (CD) model can support this well. But what does it look like with BDD then? Can BDD help implementing CD? This session is an attempt to define the role of BDD in CD. What works, what does not? Continuous delivery should mean continuous quality for the delivery team. What kind of quality criteria do we want to target with CD and how is it supported by BDD?
