Ivan Vasilov 637b6fb792 chore: update react-resizable-panels to v4 to support pixel width (#42990)
This pull request standardizes the usage of props and value types for
the `ResizablePanelGroup` and `ResizablePanel` components across
multiple files in the codebase. Specifically, it replaces the deprecated
`direction` prop with `orientation`, and updates numeric prop values
(such as `defaultSize`, `minSize`, and `maxSize`) to be passed as
strings. This ensures consistency with the updated component API and
improves type safety.

**Component API Updates:**

* Replaced the `direction` prop with `orientation` for all usages of
`ResizablePanelGroup`
* Updated all `ResizablePanel` props (`defaultSize`, `minSize`,
`maxSize`) to be passed as strings instead of numbers, ensuring
compatibility with the latest API requirements.
* Removed deprecated or unnecessary props such as `order` from
`ResizablePanel` components, and ensured all size-related props are
consistently formatted as strings.

UI Testing Notes

Rules

  • All tests should be run consistently (avoid situations whereby tests fails "sometimes")

  • Group tests in folders based on the feature they are testing. Avoid file/folder based folder names since those can change and we will forget to update the tests.

Examples: /logs /reports /projects /database-settings /auth

Custom Render and Custom Render Hook

customRender and customRenderHook are wrappers around render and renderHook that add some necessary providers like QueryClientProvider, TooltipProvider and NuqsTestingAdapter.

Generally use those instead of the default render and renderHook functions.

import { customRender, customRenderHook } from 'tests/lib/custom-render'

customRender(<MyComponent />)
customRenderHook(() => useMyHook())

Mocking API Requests

To mock API requests, we use the msw library.

Global mocks can be found in tests/lib/msw-global-api-mocks.ts.

To mock an endpoint you can use the addAPIMock function. Make sure to add the mock in the beforeEach hook. It won't work with beforeAll if you have many tests.

beforeEach(() => {
  addAPIMock({
    method: 'get',
    path: '/api/my-endpoint',
    response: {
      data: { foo: 'bar' },
    },
  })
})

API Mocking Tips:

  • Keep mocks in the same folder as the tests that use them
  • Add a test to verify the mock is working

This will make debugging and updating the mocks easier.

test('mock is working', async () => {
  const response = await fetch('/api/my-endpoint')
  expect(response.json()).resolves.toEqual({ data: { foo: 'bar' } })
})

Mocking Nuqs URL Parameters

To render a component that uses Nuqs with some predefined query parameters, you can use customRender with the nuqs prop.


customRender(<MyComponent />, {
  nuqs: {
    searchParams: {
      search: 'hello world',
    },
  },
})

<Popover> vs <Dropdown>

When simulating clicks on these components, do the following:

// for Popovers
import userEvent from '@testing-library/user-event'
await userEvent.click('Hello world')

// for Dropdowns
import clickDropdown from 'tests/helpers'
clickDropdown('Hello world')
