March 2019 Summaries

Cypress.io and Percy are collaborating to offer a comprehensive solution for end-to-end functional and visual testing of web applications, ensuring both operational functionality and visual integrity across various states and views. This partnership provides a reliable method to detect visual regressions and maintain application performance consistency with every code commit. A webinar featuring Mike Fotinakis, Co-Founder and CEO of Percy, and Gleb Bahmutov, Cypress' VP of Engineering, is scheduled for April 10, where they will demonstrate the integration of Percy's visual testing capabilities with Cypress tests, discuss writing effective end-to-end tests, and offer practical steps for achieving complete application test coverage. Participants will have the opportunity to engage in a live Q&A session and access a recording post-event, with potential incentives for registering.

Gleb Bahmutov's blog post explores the integration of application events in end-to-end tests for web applications, using Cypress.io as the test runner. It highlights the process of leveraging the Kuker library to observe Redux store events and verify that the application performs the expected actions and maintains the correct state. The post provides practical examples using a TodoMVC application, demonstrating how to spy on and assert against events during tests. By wrapping the Redux store with Kuker middleware, developers can track events in real time through Chrome DevTools, enhancing the visibility of internal processes during both normal browsing and testing. The blog also illustrates techniques for handling unpredictable web application delays and emitting custom events in frameworks like Hyperapp, while emphasizing the importance of maintaining test independence from implementation details. Overall, it showcases the utility of event-driven testing in confirming the reliability of the model layer beneath the user interface.

GoDaddy, the world's largest cloud platform for small independent ventures, collaborated with Cypress.io to enhance their internal processes and unify efforts across engineering, QA, and operations through test automation. This partnership resulted in a 75% reduction in the effort required to maintain QA tests and allowed GoDaddy to write 55% more tests with a significantly smaller team. A webinar scheduled for March 27, featuring GoDaddy team members and Cypress representatives, will cover how Cypress facilitated these improvements and transformed GoDaddy's testing culture and practices to prioritize a seamless customer experience. Participants are encouraged to attend live for an interactive session, but registrants will also receive a recording of the event.
