Automated atomic tests are a great way to improve UI tests by making them less brittle and faster. The tests focus on testing a single feature or component and have minimal UI interactions. The Talk explores examples of automated atomic tests and their implementation on web applications. It also discusses the analysis of atomic tests, login tests, and working with JSON Web Tokens for authentication and authorization. The Talk concludes by highlighting the use of UI and web requests in automated atomic testing.

This Talk discusses how to test mail service with Playwright, covering e-mail verification, reset password user journey, and more. It explores the use of third-party providers for reliable e-mail delivery and demonstrates how Playwright can help perform checks on e-mail content. The Talk also introduces the concept of a fake SMTP server and showcases how fixtures can be used to access the SMTP server and perform assertions on the HTML body of emails. Playwright's HTML rendering feature allows for interaction with email content as if it were a regular web page. It highlights the ability to render HTML from API calls, perform assertions on the rendered page, and exclude dynamically generated data from visual regression tests.

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.

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.

Daniel Irvine

Concisely Crafted

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.

CCTDD: Diseño impulsado por pruebas de componentes Cypress

Murat K Ozcan

Staff Engineer & Test Architect at Extend

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.

Software Engineer - BLIP<div><br></div>

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.

This talk explores unit testing in Angular applications, covering topics such as testing front-end applications, specifics of testing Angular, best practices, and educational resources. It discusses the anatomy of a unit test in both Jasmine and Jest, the setup and initial tests in Angular, testing user interaction and event handlers, testing rendered output and change detection, and unit testing parent components with child components. It also highlights best practices like using test doubles, testing components with dependency injection, and considerations for unit testing. Code coverage is emphasized as a metric that doesn't guarantee bug-free code.

Front End Engineer at Meta, Vest validation framework creator

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.

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.

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.

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.
