Jest tests failed after upgrading axios to v1.1.2
See original GitHub issueDescribe the bug
I updated the Axios from "axios": "^0.27.2" to "axios": "^1.1.2", and Jest tests are not working anymore with the following error:
FAIL src/app/slices/app/App.slice.test.tsx
● Test suite failed to run
Jest encountered an unexpected token
Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax.
Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration.
By default "node_modules" folder is ignored by transformers.
Here's what you can do:
• If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it.
• If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript
• To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
• If you need a custom transformation specify a "transform" option in your config.
• If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.
You'll find more details and examples of these config options in the docs:
https://jestjs.io/docs/configuration
For information about custom transformations, see:
https://jestjs.io/docs/code-transformation

SyntaxError: Cannot use import statement outside a module

To Reproduce
- Use React and Axios latest version
- Create Jest test
- Run the test to generate the error
Environment
- Axios Version
^v1.1.2 - Browser
Chrome - Browser Version
Version 105.0.5195.125 (Official Build) (x86_64) - Node.js Version
v18.4.0 - OS:
MAC OS 12.4 - React:
^18.2.0
Temporary Fix
The following fix works for now but I expect a standard fix for this issue.
"test": "react-scripts test --transformIgnorePatterns \"node_modules/(?!axios)/\"",
or
"test": "react-app-rewired test --transformIgnorePatterns \"node_modules/(?!axios)/\"",

I found that this did however work for me because it forces those imports to resolve with the CJS module instead:
"test": "react-scripts test --transformIgnorePatterns \"node_modules/(?!axios)/\""this worked, when I restart test command
