Current Behavior
When generating a new Next.js application or library, using the React 19 RC, and running the default generated test, there's a console warning:
> jest
console.warn
Warning: Your app (or one of its dependencies) is using an outdated JSX transform. Update to the modern JSX transform for faster performance: https://react.dev/link/new-jsx-transform
5 | describe("Page", () => {
6 | it("should render successfully", () => {
> 7 | const { baseElement } = render(<Page />)
| ^
8 | expect(baseElement).toBeTruthy()
9 | })
10 | })
I cannot figure out where the outdated transform is being specified - babel-jest, the @nx/next/babel preset, or the underlying next babel preset.
Expected Behavior
The new JSX transform should be used during tests
