Software development has changed - Frequent deployments, APIs, GraphQL, Cloud Architecture and CI/CD Automation are the norm. So why is security testing the same way it was a decade ago?
Leading teams are realizing that periodical penetration testing and security audits is not enough when code is being shipped daily. Instead, these teams are using developer-centric tools to run automated security testing in a CI/CD pipeline. Join Zachary Conger as he walks through how to automate application JS security testing using GitHub actions.

How to Choose an Automation Tool

How to Choose an Automation Tool
I am Lia, a software engineer at Nocare, and I'm going to show you a process to choose an automation tool. I'll compare three frameworks and discuss other integration options. Selenium is a well-established framework with a large community, but it requires third-party integrations for certain types of tests. Cypress is an all-in-one tool that supports unit testing, but it only works with JavaScript and lacks parallel testing capabilities. Playwright is a newer framework that is more complete and supports parallel testing, but it has a smaller community and less mature documentation. If you want a framework that does it all, choose Playwright. Documentation is essential to remember your initial thoughts, show others what is being tested, and establish good practice. Once you have your test list, chosen framework, and prioritizations, schedule a meeting with management. Present your work confidently, as it is the best approach for the team and product.

Dissecting Complexity in Tests
Today's Talk discusses complexity in tests and how to effectively deal with it. The speaker emphasizes the importance of testing critical user-facing paths and modeling tests from the user's perspective. They also highlight the significance of creating a testing setup that allows any test to run smoothly and the implicit testability of a well-designed system. The Talk explores the impact of choosing the right testing environment, the role of testing setup in mitigating complexity, and the importance of test structure and expectations. The speaker provides practical tips for tackling complexity in tests, such as keeping tests flat, using helper utilities, and splitting tests into separate files.
Machine Learning based Unit Tesing in JavaScript

Machine Learning based Unit Tesing in JavaScript
This talk explores machine learning-based unit testing in JavaScript and TypeScript, focusing on tools like the Pony Code VS Code extension and GitHub Copilot. The Pony Code tool provides a graphical user interface for generating and managing unit test cases. GitHub Copilot acts as an intelligent code auto-completion tool, understanding the context of the code and suggesting unit test cases. These tools aim to improve code coverage and achieve 100% coverage.
Testing CLI Utilities

Testing CLI Utilities
CLI utilities are important to test because they act as an intersection point between different parts of an application. The main challenge in testing CLI utilities is performance, which can be improved by using temporary directories. Managing ports and resources is crucial to avoid conflicts when running multiple test suites. The test context ensures that processes run in the correct context, including the use of the right directories. Running tests on different configurations helps identify compatibility issues and provides comprehensive test coverage.

Challenges of Testing and Monitoring WebRTC Applications
WebRTC is an HTML5 specification for real-time media communications between browsers and devices, with challenges in testing and monitoring. Browsers frequently update, potentially breaking WebRTC applications. Testing requires browser automation, consideration of network conditions, and device characteristics. Virtual machines and raw data injection are important for testing. Manual testing is necessary for specific workflows and scalability. Orchestrating multiple machines in the cloud and validating video, packet loss, and bit rate are challenges. Visibility and analysis of WebRTC API calls and metrics are crucial. TestRTC by Spearline offers testing and monitoring solutions.

Overtesting: why it happens and how to avoid it
This talk is about overtesting, a technique to improve test suites and testing proficiency. It addresses the common problem of spending excessive time on maintaining test suites. The goal is to maintain 100% coverage while spending equal or less time on test suites. The talk suggests splitting tests into functional units, using expect object containing for manageable expectations, and prioritizing ease of testing and time spent.

Zero Dependency Testing With Node.js
Today's Talk is about zero dependency testing with Node.js. The new test runner in Node.js supports CLI and standalone file execution, and different test runner styles are supported. Writing tests with Node.js is simple using its assert and test modules. The test runner passed one test and failed another, and future work includes implementing a tap parser and adding code coverage and mocking features.

Using Tests for What?!
Today's Talk introduces VEST, a form validation framework that combines the syntax and style of Unitest with form validation. The lack of structure in form validation is a major problem, leading to messy and difficult-to-maintain code. Testing forms and form validation can be challenging, especially with complex logic. VEST offers a solution by allowing the creation of a form validation suite using unit tests. It provides features like multiple validations per field, async validations, and memoization, with support for any JavaScript environment and full TypeScript support.

Automated Security Testing for JS Apps
At StackHawk, we do application security testing, specifically dynamic application security testing. Legacy DAST tools are not effective for testing JavaScript front ends and APIs. To achieve better testing, it is essential to drive the API directly using industry standards like postman collections, OpenAPI spec, GraphQL, and introspection queries. StackHawk simplifies finding and fixing security issues in applications, integrating with CI/CD processes and providing simple descriptions and examples.

Playwright Can Do This?
Playwright is a powerful tool for end-to-end testing, offering support for all major browsers and platforms. It provides features like parallelization, built-in waiting, and assertions. Playwright allows for running tests on multiple browsers with a single command and has functionality for generating tests and performing visual regression testing. It also enables the manipulation of the network layer and loading internals of web pages. Best practices include using short and idempotent scripts, splitting user account flows into separate tests, and cleaning up after each test case.

CCTDD: Cypress Component Test Driven Design
Cypress component test-driven design can take front-end engineers to the next level by covering TDD examples, component testing, endpoint testing, and recommended best practices. The TDD flow involves starting with failing tests, making them work, and then improving them. Component tests can be written incrementally, using custom wrappers and props. The differences between React Testing Library and Cypress Component Test lie in the API style. Code coverage can be achieved with Cypress component tests, and the Pack.js Cypress Adapter can be used to avoid test duplication between the backend and frontend.

In this Talk, Rafaela discusses Web3, its decentralized and token-based model, and the architecture based on smart contracts. Testing Web3 poses challenges due to the need for third-party providers like MetaMask. Approaches such as mocking the Web3 flow and using end-to-end testing tools like Taskafar are suggested. The trade-offs in Web3 testing include test speed and dependency on third-party apps. Balancing unit, integration, and end-to-end tasks is crucial for a robust testing strategy.
