Typing a 9-digit amount into the logs date picker's custom field built a "Last N days" helper that subtracted past the representable `Date` range, so `toISOString()` threw `RangeError: Invalid time value` while rendering the helper list — crashing both Unified Logs and Logs Explorer. `parseCustomInput` now rejects those amounts, so oversized input behaves like any other invalid input (empty helper list) instead of producing a helper that throws. Fixes FE-4426 <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Bug Fixes** - Logs date filters now reject excessively large day values outside the supported date range. - Invalid date inputs no longer generate unusable date filter options. - The date picker now displays guidance when an invalid custom format produces no matching options. - **Tests** - Added coverage for out-of-range values and confirmed valid large date ranges continue to work correctly. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Joshen Lim <joshenlimek@gmail.com>
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')
