Mock Ethereum Environment for Cypress Tests This module provides a function to set up a mocked Ethereum environment for Cypress tests. It utilizes the Web3Mock library to simulate Ethereum blockchain interactions and MetaMask wallet behavior.

Returns

void

Remarks

Key features:

Mocks the Ethereum blockchain environment
Simulates MetaMask wallet functionality
Automatically applied before each test suite

This function is typically called in the Cypress support file or test setup to ensure all tests run in a controlled, mocked Ethereum environment. It allows for consistent and predictable testing of Ethereum-based applications without the need for a real blockchain or wallet.

Example

// In your Cypress support file
import { mockEthereum } from '@synthetixio/synpress/cypress/support';

mockEthereum();
