描述

I'm getting what appears to be a bogus error:

    Expected { app: { data: {}, ui: { fetchinUser: false, fetchingInstruments: false, fetchingLoans: false, modalOpen: false, modalView: null, selectedTab: 0, sidebarOpen: false, sidebarView: null, snackbarList: [], snackbarNextId: 0 } }, form: { search: { _active: 'query', _asyncValidating: false, _error: undefined, _initialized: false, _submitFailed: false, _submitting: false, query: { _isFieldValue: true, visited: true } } } } to equal { app: { data: {}, ui: { fetchinUser: false, fetchingInstruments: false, fetchingLoans: false, modalOpen: false, modalView: null, selectedTab: 0, sidebarOpen: false, sidebarView: null, snackbarList: [], snackbarNextId: 0 } }, form: { search: { _active: 'query', _asyncValidating: false, _initialized: false, _submitFailed: false, _submitting: false, query: { _isFieldValue: true, visited: true } } } }

It would be great is failed assertions would use whyNotEqual to report the issue:

研究方向
The issue proposes using the `is equal` npm package to provide detailed diff output when assertions fail. To implement, investigate the current error reporting mechanism in the expect library (likely in files like `lib/assert.js` or similar). Then integrate `is equal` to compare expected and actual values and append the difference to the error message. No linked PRs or comments provide further guidance, so the implementer should refer to the is equal documentation and the expect source code to determine the best integration point.
