This workshop is for Cypress users who want to step up their game against flake in their test suites. Leveraging the Cypress Real World App, we’ll cover the most common causes of flake, code through some examples of how to make tests more flake resistant, and review best practices for detecting and mitigating flake to increase confidence and reliability.
Table of contents:
- Cypress Real World App Overview
- What is Flake?
- Causes of Flake
- Managing Network-related Flake (Activity)
- Managing Dom-relate Flake (Activity)
- Flake Detection and Mitigation Best Practices
- Q&A

In this three-hour workshop we’ll introduce React Testing Library along with a mental model for how to think about designing your component tests. This mental model will help you see how to test each bit of logic, whether or not to mock dependencies, and will help improve the design of your components. You’ll walk away with the tools, techniques, and principles you need to implement low-cost, high-value component tests.
Table of contents- The different kinds of React application tests, and where component tests fit in- A mental model for thinking about the inputs and outputs of the components you test- Options for selecting DOM elements to verify and interact with them- The value of mocks and why they shouldn’t be avoided- The challenges with asynchrony in RTL tests and how to handle them
Prerequisites- Familiarity with building applications with React- Basic experience writing automated tests with Jest or another unit testing framework- You do not need any experience with React Testing Library- Machine setup: Node LTS, Yarn
