https://github.com/aseemk/requireDir/blob/master/index.js#L50

const isJestEnviroment = process.env.JEST_WORKER_ID !== undefined

if (isJestEnviroment) extensions = ['.js', '.json','.mjs']

Apparently, there is a bug envolving dependencies when Jest is used with requireDir, check this thread, this comment in specific, recomends switching requireDir package for require-directory package.

The module require-directory works just fine for me along side Jest.

For me, what would be writed as:
const routesDefinition = requireDir("./routes");

was replaced by:
const routesDefinition = requireDirectory(module, "./routes");
