@refinedev/mui always throws an error during tests
When I'm writing tests with vitest and react testing library, as soon as I wrap a component with the refine provider it starts throwing this error. Does anyone know how to fix this?
I opened an issue because there doesn't seem to be any docs or examples on how to write tests https://github.com/refinedev/refine/issues/6020.

Hi @boris. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
It seems like you're encountering issues when writing tests with
@refinedev/mui
and wrapping components with the refine provider. Based on the knowledge sources, there are a few potential issues and solutions that might help you resolve this problem.
Common Issues and Solutions
1. Missing or Incorrect Data Provider Configuration:
If you encounter errors related to the data provider, ensure that you have correctly configured the data provider. For example, you might see an error like:
This can be resolved by ensuring that all required methods are added to the data provider.
2. Testing Setup:
When testing components that use refine hooks, you need to properly set up the test environment. Instead of just wrapping the component with QueryClientProvider
, you should prepare a test wrapper with the <Refine />
component. Here are some examples from the refine codebase that might help you set up your tests correctly:
- @pankod/refine-antd's test setup (https://github.com/refinedev/refine/blob/next/packages/antd/test/index.tsx#L28)
- @pankod/refine-mantine's test setup (https://github.com/refinedev/refine/blob/next/packages/mantine/test/index.tsx)
- ErrorComponent's test example (https://github.com/refinedev/refine/blob/next/packages/antd/src/components/pages/error/index.spec.tsx#L21-L27)
- Edit component's test example (https://github.com/refinedev/refine/blob/next/packages/antd/src/components/crud/edit/index.spec.tsx#L10-L55)
- useTable hook test example (https://github.com/refinedev/refine/blob/next/packages/antd/src/hooks/table/useTable/useTable.spec.ts#L27-L29)
3. Handling Specific Errors:
If you encounter specific errors like TypeError: Cannot redefine property: __esModule
, it might be related to the way refine re-exports certain modules. A suggested fix for this issue is to modify the code where the error occurs:
Example Test Setup
Here is an example of how you might set up your test environment using the <Refine />
component:

Why is it not supporting resolving ES modules? The file it's importing exists in the right place

Hey @boris, do you have the same issue if you import a mui component in your code like the screenshot above? (
import Box from "@mui/material/Box"
?
Looks like an issue with the module resolver of jest. I think this can be resolved by working on moduleNameMapper
from jest.config.js

I don't have this issue when I
import Box from "@mui/material/Box"
@aliemir are you suggesting that I configure vite to transform import Box from '@mui/material/Box';
to import { Box } from '@mui/material;
?
i'm using vitest btwambitious-aqua•5mo ago
Guessing that you’re using type=module environment, this might be happening due to directory imports not being properly resolved in esm 🤔
I will investigate the issue and try to prepare a solution. Can you add some info about your project setup in the issue?
ratty-blush•5mo ago
i'm not using type=module (adding it makes not difference to the error), the imports aren't being resolved, but idk why
i'll add more info asap

some configs i'm using

Btw, can you also add your node version to the issue? 🙏
