Looks like test are failed... |
- Introduced a new script for node test setup (`scripts/node-test-setup.mjs`) to configure snapshot serializers and resolve snapshot paths for webpack tests. - Added new npm script `test:node` in `package.json` for running node tests with specific configurations. - Updated Jest snapshots in `proxy-option.test.js.snap.webpack5` to reflect changes in test descriptions. - Refactored tests in `open-option.test.js` and `proxy-option.test.js` to utilize `jest-mock` for mocking and spying, replacing previous Jest mocking methods. - Changed `beforeAll` and `afterAll` hooks to `before` and `after` for better test isolation and readability.
…tructure - Changed snapshot test descriptions to include a more structured format. - Updated snapshot assertions to use `t.assert.snapshot` for consistency. - Refactored test setup and teardown methods to use `before` and `after` from `node:test`. - Adjusted the test cases in `normalize-options.test.js` and `validate-options.test.js` for improved clarity and maintainability.

- Refactored multiple test files to utilize the `node:test` module for structuring tests. - Replaced direct assertions with `t.assert.snapshot` for snapshot testing. - Ensured consistency across tests by adding async context to test functions. - Updated imports to include necessary testing utilities from `node:test` and `expect`.
…assertions - Replaced traditional test structure with node:test for better test organization. - Updated snapshot assertions to use the new test framework's syntax. - Ensured all test cases in web-socket-communication.test.js, web-socket-server-url.test.js, and web-socket-server.test.js are consistent with the new structure.
…organization - Updated test files to utilize the `node:test` module for better compatibility and performance. - Replaced `jest.fn()` with `jest-mock` functions for mocking in various test cases. - Enhanced snapshot descriptions for clarity and consistency across tests. - Introduced a new `jsdom-setup.js` helper to streamline JSDOM configuration for tests. - Adjusted test cases to use `t.assert.snapshot()` for snapshot assertions. - Cleaned up mock implementations and reset logic in tests for improved reliability.
- Updated package.json to remove Jest dependencies and adjust test scripts for Node's test module. - Deleted globalSetupTest.js and setupTest.js as they are no longer needed. - Refactored ReactErrorBoundary.test.js to utilize real jsdom window/document. - Updated WebsocketClient.test.js to use async/await and improved test structure. - Skipped index.test.js due to dependency on Jest's mocking capabilities. - Refactored socket-helper.test.js to create a mock WebSocketClient class. - Updated log.test.js to simplify logger tests and remove unnecessary mocks. - Enhanced jsdom-setup.js to replace jsdom's WebSocket with Node's ws library for better testing of WebSocket connections.

Okay, once CI passes, I’m going to merge it. There really aren’t any major changes, and I made it so the snapshots wouldn’t change too much, although some of them did. But those are changes I verified myself. Jest components are still being used, but everything works normally. Otherwise, this PR would become even bigger, and I need this to unblock the http-proxy-middleware update, since Jest was a factor preventing us from updating it.

t may look weird to run the test runner like that, but with so many flags there was a point where the fixtures were getting executed too, so I had to filter them out. And when using test-shard, it wouldn’t recognize them because of a Node.js bug, so this was the workaround.

So the snapshots can keep working very similarly to how they worked with Jest, since there isn’t enough time to migrate to the Node.js format.
