jest, @testing-library/react errors

[shipswake]

I am trying to write tests using @testing-library/react and jest.
I am unable to get the tests to run due to this line in the @finos/fdc3
export * from '@finos/fdc3-context';
Seems the export is not recognized as valid.

Has anyone come across this and know how to fix it?

I have only vague memories of encountering this... A few things to check:

• Have you got that library in your package.json as a direct dependency? @finos/fdc3 depends on it so it should come in as a transitive dependency, but doesn't hurt to check.
• After an npm install, does the package exist in your node_modules directory?
• Does this only fail in your own project and not in a fresh checkout of the fdc3 repository (if so there must be come configuration difference)?
• What are your npm and node versions?

It only fails in the tests

Seems setting transformIgnorePatterns: [], in the jest config fixed it

I had the same issue. Take a look at https://github.com/finos/FDC3/blob/fdc3-security-monorepo/toolbox/fdc3-security-implementation/package.json to see how I fixed it
