Increase Jest unit test coverage for the Swaps feature to ~25% (#10900) * Swaps: Show a network name dynamically in a tooltip * Replace “Ethereum” with “$1”, change “Test” to “Testnet” * Replace 이더리움 with $1 * Translate network names, use ‘Ethereum’ by default if a translation is not available yet * Reorder messages to resolve ESLint issues * Add a snapshot test for the FeeCard component, increase Jest threshold * Enable snapshot testing into external .snap files in ESLint * Add the “networkNameEthereum” key in ko/messages.json, remove default “Ethereum” value * Throw an error if chain ID is not supported by the Swaps feature * Use string literals when calling the `t` fn, * Watch Jest tests silently (no React warnings in terminal, only errors) * Add @testing-library/jest-dom, import it before running Jest tests * Add snapshot testing of Swaps’ React components for happy paths, increase minimum threshold for Jest * Add the test/jest folder for Jest setup and shared functions, use it in Swaps Jest tests * Fix ESLint issues, update linting config * Enable ESLint for .snap files (Jest snapshots), throw an error if a snapshot is bigger than 50 lines * Don’t run lint:fix for .snap files * Move `createProps` outside of `describe` blocks, move store creation inside tests * Use translations instead of keys, update a rendering function to load translations * Make sure all Jest snapshots are shorter than 50 lines (default limit) * Add / update props for Swaps tests * Fix React warnings when running tests for Swaps
