While Maven has a larger user base and central library repository, Gradle is more flexible, supports Groovy scripts, and offers faster builds. The document then demonstrates using Gradle to generate a Spring Boot project that exposes an endpoint.
Migration from AngularJS to Angular
This document discusses migrating from AngularJS to Angular while maintaining support for legacy AngularJS code and routes. It covers using UI-Router for routing in a hybrid app, the ngUpgrade module for integrating Angular and AngularJS components, and a sample app that demonstrates how to migrate routes, components, and connect the two frameworks. Key steps in the migration include preparing the AngularJS app, configuring UI-Router, bootstrapping both frameworks, and using ngUpgrade to share components between the frameworks.
Introduction cypress
This document introduces Cypress, an open-source test runner for front-end applications. It is described as fast, easy to use, and reliable for testing anything that runs in a browser. Key benefits highlighted include being fast, open source, working on any front-end framework, being friendly for developers and QA engineers using JavaScript, and having features like time travel and real-time reloading. The document also provides instructions on installing Cypress and running tests using its GUI runner or headless mode.
End to end test automation with cypress
This document discusses testing AngularJS applications and compares different tools for doing so. It notes that while Selenium can be used to test Angular applications, tools like Cypress.io and Protractor make it easier by handling asynchronous loading and supporting Angular-specific locators. The document then introduces Cypress.io as an all-in-one tool that provides features like an interactive test runner, faster test execution, better debugging, and reporting capabilities. It provides a simple example of using Cypress.io and also lists some current limitations.
Cypress
Cypress is a testing tool that allows for fast, easy, and reliable testing of anything that runs in a browser. It differs from other tools in that it does not use Selenium, focuses on end-to-end testing, works on any front-end framework, uses only JavaScript for tests, and runs much faster than other options. Cypress tests the application as a real user would and allows debugging of test flows. It also supports plugins, common commands and assertions, and has a similar syntax to unit testing frameworks.
Getting Started With Cypress
This session aims to shed some light on an emerging test automation tool, Cypress. Cypress resolves many of the test automation problems that a QA or a dev may face in UI Web Automation testing. And after a walkthrough, we will compare cypress with Selenium as well.

Practical continuous quality gates for development process
There are a lot of books and publications about the continuous integration in the world. But in my experience it’s difficult to find information about how to open quality gates between automated tests and to continuous integration practice to in your current project. After reading several articles and even a couple of books you will understand how to work with it. But what next? I will share with you practical tips and tricks on how to lift iron curtain to your automated tests before a continuous quality practice today. It is for this reason why I am pleased to share with you my acquired experience in my presentation.
Introduction to continuous delivery
Continuous delivery is a software development practice where software can be released to production at any time by building software in a way that enables frequent, automated releases. It involves practices like continuous integration, where code is automatically merged and tested frequently, automated testing and deployment, and using deployment pipelines and tools to streamline the release process. Many large tech companies practice continuous delivery, with some deploying new code in minutes or every 11 seconds to get changes to users quickly.
Merge hells - Feature Toggles to the rescue
The document discusses how feature toggles can help address "merge hells" that can occur with continuous integration. Feature toggles allow incomplete features to be deployed without being released, avoiding the need to rollback deployments. They enable options like A/B testing, canary releasing, and managing experimental and operations toggles. To manage feature toggles, teams should follow mainline development practices, use feature toggle tools, set expiry dates for toggles, and consider toggles as a first step towards continuous delivery.
Angular Ivy- An Overview
Ivy is Angular's next generation compiler and renderer that aims to make applications smaller, faster to load, and use less memory. Some key goals of Ivy include faster initial loading, reduced bundle sizes, lower memory footprint, improved memory allocation, and faster compilation times. Ivy generates template instructions directly from templates rather than generating intermediate metadata, making the compilation process more efficient. It also uses incremental DOM for rendering, which creates and updates DOM trees using in-place instructions rather than full virtual DOM comparisons on each change. Tree shaking also works more effectively with Ivy due to its generation of smaller, more atomic functions from templates.
Protractor end-to-end testing framework for angular js
Protractor is an end-to-end test framework for AngularJS applications that runs tests against a real browser, interacting with the application as a user would. It is built on WebDriverJS and uses native events and browser-specific drivers to test asynchronous behavior and support for AngularJS. Protractor tests can run in any browser and interact directly with page elements rather than testing JavaScript code.
Angular TS(typescript)
This document discusses using TypeScript with Angular to prepare code for migration to Angular 2. It recommends using TypeScript for its static typing and compile-time type checking. It provides steps for modifying an existing Angular project to use TypeScript and approximate Angular 2 components to ease the migration. Key aspects include refactoring data flows, replacing ng-include and ng-controller with component directives, and wrapping markup in component directives.

Dynamic Security Testing
Zap is a free and open source security testing tool that can find vulnerabilities in web applications. It has two modes - passive and active scanning. Passive scanning inspects traffic while active scanning attacks the application by running exploits. Zap found issues like insecure cookies and missing security headers during passive scanning of Tweek. For active scanning, Zap parsed Tweek's OpenAPI specification and found additional vulnerabilities. Glue is an OWASP tool that helps integrate Zap and other security tools into continuous integration pipelines. It filters and reports findings to help prioritize issues. Adding security testing with Zap and Glue helped find and fix vulnerabilities before they affected users.

Protractor provides AngularJS-specific APIs and tools to help with debugging on top of WebDriverJS. Functional tests are the foundation of quality but should be isolated and decoupled from the UI using patterns like page objects. Protractor is ready to use today for testing AngularJS applications.
Testing, CI and CD in the real world
The document discusses different types of software testing including unitary tests, integration tests, and instrumentation tests. It provides examples of how unitary tests can be used to develop regular expressions, parse deep links, improve an invoice generator, and refactor legacy code. Tips are provided on following a given-when-then style for unitary tests and testing one thing at a time. Integration tests and instrumentation tests are discussed for developing APIs and testing apps end-to-end. Continuous integration and continuous delivery are also summarized.
Automated Testing using JavaScript
Automated testing of web applications using JavaScript can provide confidence that changes and new installations do not break existing functionality. There are various types of tests, including unit, end-to-end, compatibility, and performance tests. Popular JavaScript testing tools include QUnit for unit testing, Selenium and Protractor for end-to-end testing, and PhantomJS for headless browser testing without a GUI. These tools can test JavaScript applications and allow writing tests in JavaScript when the application itself is also written in JavaScript.

Java and Spring Data JPA: Easy SQL Data Access
Abstract
Presenter: Miya W. Longwe, MBA, MSE, Tech Lead, Staples, Inc, Framingham MA 01702
Accessing data repositories in various applications programming languages typically involves writing of tedious boilerplate lines of code. Some application development frameworks such as Spring have tried to make the experience more succinct by providing abstraction layers such as HibernateTemplate and JdbcTemplate, etc. Despite these APIs, the developers still spend a lot time writing repetitive code than concentrating on implementing business requirements. Developers at Spring, led by Oliver Gierke, introduced Spring Data JPA which “aims to significantly improve the implementation of data access layers by reducing the effort to the amount that's actually needed. As a developer you write your repository interfaces, including custom finder methods, and Spring will provide the implementation automatically”.
Spring Data JPA provides a powerful, out-of-the-box alternative to creating your own DAO framework. You declare custom repository operations on an interface, and the framework generates dynamic implementations (not code generation) automatically, based on conventions around method names. As part of the presentation, we'll also review a demo to look at Spring Java configuration (as opposed to XML configuration), and investigate the @Profile annotation – configuration details which may make life a bit easier in various ways when setting up unit testing of our repository classes, using out-of-the-box alternative to creating DAO framework, how to create custom repositories, pagination and support for custom queries among other features.

Mongo db with spring data document
This document discusses using MongoDB with Spring Data. It shows how to configure MongoDB drivers and templates as beans in Spring. It also demonstrates how to perform CRUD operations on MongoDB documents using Spring Data's MongoRepository interface, including implicit conversion between Java objects and MongoDB documents. Key features of MongoRepository discussed include query methods, custom queries, and asynchronous support.
Spring introduction
Spring Framework is a popular and stable Java application framework that reduces dependencies and provides solutions to common coding problems like working with databases and web services. It uses dependency injection and aspect-oriented programming to increase modularity. The framework manages Java objects called beans, creating and injecting their dependencies based on bean definition files. This allows applications to access services without needing to understand their implementation.
Spring aop concepts
Aspect-Oriented Programming (AOP) complements Object-Oriented Programming (OOP) by providing another way of thinking about program structure. The key unit of modularity in OOP is the class, whereas in AOP the unit of modularity is the aspect. Aspects enable the modularization of concerns such as transaction management that cut across multiple types and objects. (Such concerns are often termed crosscutting concerns in AOP literature.)
One of the key components of Spring is the AOP framework. While the Spring IoC container does not depend on AOP, meaning you do not need to use AOP if you don't want to, AOP complements Spring IoC to provide a very capable middleware solution.
Practical Ruby Projects With Mongo Db
The document provides an overview of MongoDB and how it can be used practically with Ruby projects. It discusses how MongoDB simplifies schema design by allowing embedded documents that match how objects are structured in code. This avoids the need to map objects to SQL schemas. Examples are given of how MongoDB could be used for a blogging application with embedded comments and tags, for logging with capped collections, and for an accounting application with embedded transaction entries. The document also introduces MongoMapper as an ORM for MongoDB that provides an ActiveRecord-like syntax for modeling documents and relationships in Ruby code.
