cypress-firebase

Cypress-firebase is a developer tool plugin that extends Cypress testing with custom commands for interacting with Firebase services like Firestore and Authentication. It is designed for developers building Firebase-backed applications who want to write reliable, end-to-end tests that can seed data, mock authentication states, and verify backend behavior directly within Cypress. Its value lies in bridging the gap between frontend testing and Firebase’s server-side logic, enabling more realistic and efficient test suites without manual setup.
