Getting "Error: Unused file" when running test for new type definition

Question

I created a new type definition within the DefinitelyTyped project for the hyphen library. You can see it here.

However when running the test script npm run test hyphen I get the following error message:

C:\MyProjects\code\ts-d.ts\DefinitelyTyped>npm run test hyphen

> [email protected] test C:\MyProjects\code\ts-d.ts\DefinitelyTyped
> node node_modules/types-publisher/bin/tester/test.js --run-from-definitely-typed "hyphen"

The error says that index.d.ts is an unused file. But this is not true as it is used within my hyphen-tests.ts file.

I could add index.d.ts to OTHER_FILES.txt to bypass the problem, but this is obviously not the right solution. Can someone help me out here? Thanks in advance.

Answer 1

I turns out I was missing the index.d.ts entry in the files option within my tsconfig.json:

{
    "compilerOptions": {
        "module": "commonjs",
        "lib": [
            "es6"
        ],
        "strict": true,
        "baseUrl": "../",
        "typeRoots": [
            "../"
        ],
        "noEmit": true,
        "forceConsistentCasingInFileNames": true,
        "types": []
    },
    "files": [
        "index.d.ts",
        "hyphen-tests.ts"
    ]
}

But I still don't know why it has to be there as all other .d.ts files are recognized through their respective imports within hyphen-tests.ts.
