The process of setting up Cypress tests in a TypeScript environment using Create React App v3 is outlined in this guide, which begins with creating a new TypeScript project and integrating Cypress for end-to-end testing. It involves installing necessary dependencies like Cypress and a utility package (@bahmutov/add-typescript-to-cypress) to enable TypeScript support. The setup requires some configuration adjustments, such as modifying the TypeScript settings to allow code emission, which is essential for running tests successfully. Potential issues with dependency conflicts, such as those involving babel-loader versions, are addressed by updating the .env file to bypass preflight checks. The article provides a sample test to verify the setup and emphasizes the use of modern IDEs like VSCode for enhanced code completion. The complete source code and further resources on using TypeScript with Cypress are available in the bahmutov/cra-cypress GitHub repository.
