Sí, las cosas grandes vienen en paquetes pequeños. Por ejemplo, ¿no es fantástica la velocidad, retroalimentación y confiabilidad de una prueba unitaria? ¿Sabías que también podemos obtener retroalimentación rápida, enfocada y confiable de nuestras pruebas funcionales de extremo a extremo? Las pruebas atómicas de extremo a extremo son aquellas que son específicas y enfocadas. Son pequeñas en tamaño pero tienen un gran impacto. Este tutorial te enseñará cómo crear pruebas atómicas de extremo a extremo con varios ejemplos de código. Primero, utilizaremos Cypress.io para autenticarnos mediante la configuración de una cookie en lugar de utilizar una interfaz de usuario. Segundo, utilizaremos Cypress.io para establecer un JSON Web Token para la autenticación. Únete a mí y escribamos pruebas pequeñas para obtener grandes resultados.

Pruebas pequeñas, grandes resultados

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.

Yes, Big things do come in small packages. For example, isn’t a unit test’s speed, feedback, and reliability fantastic? Did you know we can also have fast, focused, and reliable feedback from our functional e2e tests? Atomic e2e tests are those that are targeted and focused. They’re tiny in size but large in their impact. This tutorial will teach you how to create atomic e2e tests with several code examples. First, we will use Cypress.io to authenticate by setting a cookie. Instead of using a UI. Second, we will use Cypress.io to set a JSON Web Token for authentication. Join me, and let’s write tiny tests for large results.

Tiny Tests, Large Results

Enviamos correos electrónicos a nuestros usuarios - verificación de cuenta y boletines informativos. Permitimos que el usuario nos contacte enviando un correo electrónico a través de un formulario incorporado. ¿Lo hacemos? ¿Recibe el usuario un correo electrónico de verificación de cuenta o exactamente la notificación para la que se inscribió? Podemos cubrir esta funcionalidad como parte de las pruebas E2E: obtener un correo electrónico y abrirlo para verificar qué contiene. Necesitaremos Playwright y un servidor SMTP falso para capturar los correos electrónicos enviados por la aplicación.

Prueba del Servicio de Correo con Playwright

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.

We send emails to our users - account verification and newsletters. We allow the user to contact us by sending an email via inbuild form. Do we? Does the user receive an account verification email or exactly what notification they signed up for? We can cover this functionality as part of E2E tests: get an email and open it to check what is in it. We will need Playwright and a fake SMTP server to capture emails sent by the app.

Overtesting es un problema común con las suites de pruebas unitarias. Es cuando tienes demasiadas pruebas que se rompen con frecuencia y requieren mucho tiempo para mantenerlas en verde. Aquí tienes una nueva perspectiva sobre por qué ocurre esto y cómo puedes evitarlo.

Overtesting: por qué ocurre y cómo evitarlo

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.

Overtesting is a common problem with unit test suites. It's when you have too many tests that break often and take up a large amount of time to keep green. Here's a fresh perspective on why that happens and how you can avoid it.

Las arquitecturas distribuidas modernas son más complejas que nunca, con la mayoría de las empresas operando en múltiples lenguajes, protocolos y estilos arquitectónicos. Esto plantea desafíos significativos para los equipos de ingeniería que cada vez más se les pide entregar más rápidamente. Si bien la práctica de las pruebas de contrato se hizo prominente durante el auge de los microservicios RESTful para abordar desafíos similares, la declaración del problema ha evolucionado. En esta charla, discutiremos estos nuevos desafíos y demostraremos cómo las pruebas de contrato siguen siendo tan relevantes como siempre para ayudar a resolverlos.

Más allá de REST - Pruebas de contrato en la era de gRPC, Kafka y GraphQL

This talk explores the challenges of API communication in a multi-protocol environment and the limitations of REST. It discusses how contract testing can address these challenges by focusing on API communications and reducing reliance on end-to-end tests. The talk also examines the limitations of specifications like OpenAPI and JSON schema and the challenges of endpoint evolution and versioning. It highlights the benefits of consumer-driven contract testing in ensuring API compatibility and provides an overview of the PACT framework as a standardized solution. 

Modern distributed architectures are more complex than ever before, with a majority of companies operating multiple languages, protocols and architectural styles. This poses significant challenges for engineering teams increasingly asked to deliver more at speed. Whilst the practice of contract testing rose to prominence during the RESTful microservices boom to address similar challenges, the problem statement has evolved. In this talk, we'll discuss these new challenges and demonstrate how contract testing is still as relevant as it has ever been in helping to solve them.

¿Cuáles son los aspectos que debes tener en cuenta al elegir un marco de automatización? Algunas diferencias principales entre los marcos disponibles.Explica las principales diferencias entre los marcos más conocidos para la automatización: Selenium, Cypress, Playwright y Robot Framework. Aspectos positivos y negativos de los marcos. Dependiendo de las necesidades del proyecto en el que trabajas, ¿cuál es el mejor marco para usar? Breve conversación sobre cómo los marcos se integran con algunas herramientas de gestión de pruebas.

Cómo elegir una herramienta de automatización

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.

What are the aspects you should think when choosing an automation framework. Some main differences on available frameworks.Explain the main differences between the most known frameworks for automation: Selenium, Cypress, Playwright and Robot Framework. Positives and negatives about the frameworks. Depending on the needs of the project your work what is the best framework to use. Small talk about how frameworks integrate with some test management tools.

Pruebas de utilidades de línea de comandos

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.

Ever wondered what is the best way to end-to-end test your custom command line utilities? In this talk Florian Rappl will give you some insights what you can do to automatically verify your CLI tools and avoid regression.- Introduction: Why test CLI tools- Challenges: File system pollution, network and database issues, environment variables- Demo: Showcase issues with a demo CLI tool - Solutions: Test plan implementation, choosing the right level of containerization- Demo: Show solution using the previous CLI tool- Conclusion

En este masterclass, te presentaré el proyecto migrator.cypress.io de una manera poco convencional, donde además de repasar los comandos de Cypress equivalentes a Protractor (y mostrarte lo simple que es Cypress), también te mostraré cómo probé dicho proyecto evolucionando los scripts de prueba automatizados según la demanda, arquitecturando el conjunto de pruebas de forma evolutiva.

The Workshop on Migrator.cyprus.io covered the migration of Protractor test scripts to Cypress using the Migrator.cyprus.io application. The workshop included running tests, discussing project architecture, and code improvements. Custom commands were introduced to reduce code duplication. The workshop also covered guidelines for writing code, version updates, and optimization techniques. Participants shared their experiences and recommendations for using Cypress for UI and API testing.

In this workshop, I will introduce you to the migrator.cypress.io project in an unconventional way, where in addition to going over the Cypress commands equivalent to Protractor (and showing you how Cypress is simpler), I will also introduce you how I tested such a project evolving the automated test scripts on-demand, architecting the test suite in an evolutionary way.

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.
