Stripe con 2021 UI stack
The document summarizes the history and current state of the Silverstripe CMS user interface stack. It describes how the stack originally used a mismatch of legacy technologies like jQuery, Entwine, and templates. It then overhauled to use modern technologies like Webpack, React, Redux, and GraphQL. However, the legacy stack is still in use alongside the modern one, resulting in a hybrid "weird" stack. The document advocates embracing this weirdness and focuses on incremental improvements within these constraints.
Building Reliable Applications Using React, .NET & Azure
Building a small to medium size business application with React isn't terribly hard. It has been done lots of times and there is plenty of information about what works and what doesn't. However building a large, complex and mission critical application with React is another matter. How to configure reliable hosting on Azure for the front and back-end? How to track runtime errors that happen in the browser. And how to create an efficient workflow between front and back-end teams. In this session Maurice de Beijer will share his experiences in building a globally deployed application that is used by thousands of people who depend on the availability and proper functioning of the application for a safe work environment.

Building large and scalable mission critical applications with React
Building a small to medium size business application with React isn't terribly hard. It has been done lots of times and there is plenty of information about what works and what doesn't. However building a large, complex, distributed and mission critical application with React is another matter. Add occasional poor mobile connectivity and things become really challenging. That doesn't mean that it is impossible, it is just harder to architect and develop. In this session Maurice de Beijer will share his experiences in building a globally deployed application that is used by thousands of people who depend on the availability and proper functioning of the application for a safe work environment.

Micro frontends is a design pattern that splits an application into multiple independently deployable frontend applications to reduce dependencies between teams and improve the speed of delivery. This approach can reduce execution and delivery risks like long cycle times and inconsistent user experiences. It allows for more autonomous teams and faster time to market. However, it also introduces some risks around broken user interfaces if components are not built consistently. Adopting a micro frontends approach requires buy-in from engineering leadership as well as change management to shift teams away from old habits.
Typescript presentation
This document provides an introduction to using TypeScript with React. It discusses how TypeScript extends JavaScript with types to make code less prone to errors and more readable and maintainable.

It also provides guidance on adding TypeScript to an existing React application project.
How do I write Testable Javascript - Presented at dev.Objective() June 16, 2016
Everyone who wasn't writing JavaScript, probably is now. Atwood's Law: any application that can be written in JavaScript, will eventually be written in JavaScript.
That's great, but how do we test it? In ColdFusion we have CFCs, most languages have classes... but JavaScript doesn't have classes (yet).
So how do I write unit tests, what units are there, and how do I make my code look like that? JavaScript is a flexible language, and with great flexibility comes great complexity and responsibility. Take your JavaScript spaghetti and make it unit testable.
Attendees should have some exposure to JavaScript, but this is for the Professional Newbie... who always needs to learn and adapt.
JAVASCRIPT Test Driven Development & Jasmine
The document discusses test driven development and the JavaScript testing framework Jasmine. It provides an overview of unit testing and test driven development processes. It then describes key aspects of Jasmine such as describing test suites and specifications, using matchers and assertions to test expectations, setting up tests using beforeEach and tearing them down using afterEach, creating custom matchers, spying on functions, and handling asynchronous tests. The document aims to introduce readers to testing JavaScript code using the Jasmine framework.

This talk has a very long demo
JavaScript Unit Testing
This document provides an agenda for a Salesforce World Tour event in London on May 21, 2015. It includes an introduction and overview of JavaScript unit testing challenges on the Salesforce platform. It also describes tools like QUnit, Sinon.js, and Blanket.js that can be used for JavaScript unit testing. Finally, it discusses approaches for testing Visualforce and Lightning Components.
Testing javascript in the frontend
The document discusses test-driven development (TDD) and how to test JavaScript code from a frontend perspective. It goes through the TDD cycle of writing a failing test first, then just enough code to pass the test, and refactoring. It provides examples testing user interaction, DOM manipulation, and mocking methods like Date and browser APIs. The goal is to write tests for all aspects of a date picker component, including showing/hiding on focus/click and adding a "selected" class. Tips provided include finding bugs to write tests for, pairing during TDD, using web APIs in tests, and not testing the browser itself.
The Developer Experience
We all know what “user experience” is and we know that it’s important. But we rarely talk about the “developer experience” - what we all go through each time we try to use a developer tool, library, or API. How do we decide what tool to use? Is it easy to integrate with our development environment? How flexible is the API? Where do we go when something goes wrong? Those are the sort of questions that we can ask to understand what it’s like for a developer to use a product - and where it can be improved. Whether you simply use developer products or you actually build one yourself, you should walk away from this talk with ideas on how to make a great developer experience - and why it matters.
Unit Testing Lightning Components with Jasmine
Slide deck for my Dreamforce 16 talk on unit testing your lightning components JavaScript with the Jasmine library.
Developer Experience to Testing
Create Software Design with unit testing, build user experience with UX testing, check definition of done with functional testing – all these are my day-to-day activities. Indeed, I am a developer who has found the value of testing to deliver quality software.
In this presentation I share with you how I have come to use tests for: understanding the features, choosing the best user experience design, choosing the best technical solution, implementing the features and test them to create a reliable system.
You will see practical examples of how tools like Jasmine, Spock, Geb are used for the above types of tests. You will see a project with test code and we will discuss how testing can effectively enhance your professional performance.
CasperJS and PhantomJS for Automated Testing
CasperJS is a browser navigation scripting & testing utility written in Javascript for PhantomJS or SlimerJS.
PhantomJS is a scripted, headless browser used for automating web page interaction. PhantomJS provides a JavaScript API enabling automated navigation, screenshots, user behavior and assertions making it a common tool used to run browser-based unit tests in a headless system like a continuous integration environment. PhantomJS is based on Webkit making it a similar browsing environment to Safari and Google Chrome (before Chrome's fork of webkit evolved into Blink). It is open-source software released under the BSD License.

So how do I write unit tests, what units are there, and how do I make my code look like that? JavaScript is a flexible language, and with great flexibility comes great complexity and responsibility. Take your JavaScript spaghetti and make it unit testable.
Attendees should have some exposure to JavaScript, but this is for the Professional Newbie... who always needs to learn and adapt.

Varshneya samdarshi lmu_symposium_2016
Poster presented at the Loyola Marymount University 8th Annual Undergraduate Research Symposium on March 19, 2016 and at the Experimental Biology Conference held in San Diego, California on April 4, 2016. Abstract: GRNsight is an open source web application and service for visualizing models of gene regulatory networks (GRNs). A gene regulatory network consists of genes, transcription factors, and the regulatory connections between them which govern the level of expression of mRNA and protein from genes. GRNmap, a MATLAB program that performs parameter estimation and forward simulation of a differential equations model of a GRN, can mathematically model the dynamics of GRNs. GRNsight automatically lays out the network graph based on GRNmap output spreadsheets. GRNsight uses pointed and blunt arrowheads, and colors the edges and adjusts their thicknesses based on the sign (activation or repression) and magnitude of the GRNmap weight parameter. Visualizations can be modified through manual node dragging and sliders that adjust the force graph parameters. We have now implemented an exhaustive unit testing framework using Mocha and the Chai assertion library to perform test-driven development where unit tests are written before new functionality is coded. This framework consists of over 160 automated unit tests that examine over 450 test files to ensure that the program is running as expected. Error and warning messages inform the user what happened, the source of the problem, and possible solutions. The completion of the testing framework marks the close of development for version 1 (the current release stands at version 1.12). In version 2.0 of GRNsight, a new feature will be implemented that colors the nodes (genes) based on expression data provided by GRNmap. GRNsight is available at http://dondi.github.io/GRNsight/.
Introduction To Web Application Testing

Unit-testing and E2E testing in JS
Unit testing and end-to-end (E2E) testing are important types of automated testing for JavaScript applications. Unit tests focus on testing individual functions or components in isolation to catch bugs, while E2E tests ensure that user flows work as expected by interacting with the application through a browser. The presentation discussed setting up testing frameworks like Karma and Jasmine for unit testing and Protractor for E2E testing. It also covered writing testable code, handling dependencies through dependency injection, and selecting elements and interacting with them during E2E tests.
Web based automation testing on Node.js environment
This document discusses web-based automation testing on Node.js. It covers unit testing frameworks like Mocha and Chai, the Selenium framework for browser automation, and Nightwatch which combines Selenium, Mocha and Chai. Nightwatch allows writing tests in a BDD style and executing them across different browsers. The document also discusses non-GUI testing with PhantomJS and integrating tests with Jenkins for continuous integration.

Web Application Software Testing
Building websites like applications means bringing more attention to testing. From unit tests early on to load and regression testing later in the game, the primary purpose of testing is to detect software failures so that defects are discovered and corrected before they make it to the customer. Depending on your size, different testing strategies and things like automation may or may not be necessary. I'll cover some great free tools, some simple command line scripts as well as some commercial choices for the various types of testing.

Automate across Platform, OS, Technologies with TaaS
"TaaS" is an open-source product that allows you do achieve the "correct" way of doing integration testing across a variety of products via Test Automation.
Typically in organizations, there are multiple projects / products. Many organizations like to have a common Test Automation solution across these products in an effort to standardize the framework.
However, this is not a good idea! Each product should be tested using the tools and technologies that are "right" for it. Yet - these different products talk with each other and you need to test the integration between them in an automated way.

✓ Framework- Can be used with other frameworks too, but can be especially useful in case you want to run functional tests not as part of other framework.
✓ Syntax- looks the easiest and the most readable.
CONS OF NIGHTWATCHJS
✓ Return value methods should only use call backs
✓ Call backs should given for every steps
9. COMPARISON OF TOOLS and CONCLUSION:
HERO of the Javascript Frameworks because:
For an E2E Testing, the webdrive.io, is still evolving, Nightwatch will be a great and also is easy to use the framework
Also it has very good inbuilt Debugging mechanism. Hence, Nightwatch is good for the E2E Testing
NightWatchJS is itself is test runner, framework and having its own assertion library
Integration testing in enterprises using TaaS
The document discusses Test as a Service (TaaS), an approach to testing software across different platforms and technologies. TaaS defines contracts that specify tests and parameters. Test frameworks on different platforms implement the contracts. A TaaS server runs the tests by invoking the contracts and returning results. This allows reusing tests across platforms without duplicating code and decoupling test technologies. The approach is applied to testing different versions of Microsoft Outlook across Windows, Mac, Android and web.

Improve Productivity with Continuous Integration & Delivery
Continuous Integration (CI) is a software development practice where developers merge their code changes into a central repository, after which automated builds and tests are run. Using CI, you can find and address bugs more quickly; improve software quality; and reduce the time it takes to validate and release new software updates. With Continuous Delivery (CD), code changes are automatically built, tested, and prepared for a release to production. With CD, developers will always have a deployment-ready build artifact that has passed through a standardized test process, enabling teams to be more agile and increasing the pace of innovation.
Wading through treacle? Escape the integration syrup with contract tests
The document discusses using contract tests to decouple development and delivery of services that depend on external systems. It proposes:
1) Writing tests that exercise services based on the agreed interactions or "contract" rather than testing against real external systems, which may be slow, unstable or inaccessible.
2) Using stateful "fakes" that mimic external systems behavior to allow running contract tests quickly without depending on external services.
3) Sharing contract tests between services so they can validate compatibility before releases to catch issues early.
Code review automation and functional tests on Carrefour
Jenkins is used to automate the software development lifecycle including builds, tests, deployments, and more. A deployment pipeline promotes code through development, QA, and production environments running tests at each stage. Cucumber, Capybara, and Selenium are used for behavior-driven development and automated functional tests across different browsers and machines in parallel. SonarQube analyzes code quality after each build and will stop the pipeline if issues are found, reporting them to the development team.
Andrea Di Persio
1) The document discusses a presentation about Go and microservices given by Andrea Di Persio, a backend engineer at SoundCloud.
2) It covers an introduction to Go as a programming language, how SoundCloud uses Go and microservices in their infrastructure and applications, and how SoundCloud implements microservices using Go.
3) Some benefits of using Go and microservices at SoundCloud include isolated services that are easier to reason about and deploy independently while still being able to experiment and take ownership of specific domains.
Continuous Integration with Amazon ECS and Docker
One of the most fundamental challenges of CI/CD is the ability to balance between Quality, Time, and Cost. Amazon EC2 Container Service (ECS), along with Docker and Amazon EC2 Container Registry (ECR), has changed the game for many by making resource management very simple. For Okta, it has enabled the Continuous Integration team to maximize throughput while minimizing cost. In this session we will show you how Okta has created a flexible CI system with ECS, Docker, ECR, AWS Lambda, AWS CloudFormation, Amazon RDS, and Amazon SQS. Okta runs 30,000 tests with each developer commit, and releases 10,000 new lines of code each week to production. The CI system, built 100% on AWS, must be able to handle load while keeping cost under control. This talk is oriented toward developers looking to achieve efficient resource and cost management without compromising speed or quality.
