Problem in the tsconfig.json file when trying to use Jest with Typescript

The error message I am getting is:

File 'd:/Project/server/jest.config.ts' is not under 'rootDir' 
'd:/Project/server/src'. 'rootDir' is expected to contain all source files.
The file is in the program because:
Matched by include pattern '**/*' in 'd:/Project/server/tsconfig.json'

My tsconfig.json file is:

{
 "compilerOptions": {
    "target": "es2020",
    "module": "commonjs",

    "rootDir": "./src",
    "outDir": "./dist",
    "esModuleInterop": true,
    "forceConsistentCasingInFileNames": true,
    "strict": true,
    "skipLibCheck": true
  }
}

My jest.config.ts file is:

export default {
    clearMocks: true,
    collectCoverage: true,
    coverageDirectory: "coverage",
    coverageProvider: "v8",
    transform: {
        "^.+\\.(t|j)sx?$": ["@swc/jest"],
    },
};

I am trying to exactly follow the directives of each documentation.

What am I doing wrong here?

>Solution :

You have to move your jest.config.ts file inside your src/ directory in order to work. The error is self explanatory I would say.
