When testing an IntL money conversion inside Jest, I don't get the correct conversion.
My test:
expect(new Intl.NumberFormat('pt-BR', { style: 'currency', currency: 'BRL' }).format(50.00)).toBe('R$ 50,00');
// Expected value to be:
// "R$ 50,00"
// Received:
// "R$ 50.00"When testing an IntL money conversion inside Jest, I don't get the correct conversion.

How can I set the correct locale configuration to Jest?

Reset to default 9UPDATE: Full ICU now es with Node.js, since version 13.
Original answer:
The challenge here is to set Node.js i18n, Jest is Node.js based.
Accordingly, with official Node.js documentation, we must set the full-icu parameter.
npm install full-icu
NODE_ICU_DATA=node_modules/full-icu jest --config jest.conf.js
Now the test is correct.
Probably in Brazil use ma sign, to separate decimal numbers. Instead of dot sign ..
Here is the link to world map which indicates which country, uses which decimal indicator.
