react-intl VS mocha

I am developing an application with react/redux, and I started using library react-intl for formatting messages and dates.

I have been struggling mocking React-Intl library with Jest because I'm having this error when I run tests:

export function categoryIdToCategoryName(categoryId) {let name;switch (categoryId) { case constants.RISK_CATEGORY_LOW: name = 'low'; break; case constants.RISK_CATEGORY_MEDIUM: name = 'medium'; break; case constants.RISK_CATEGORY_HIGH: name = 'high'; break; case constants.RISK_CATEGORY_CRITICAL: name = 'critical'; break; default: console.warn('see: /utils/risk.js', 'categoryIdToCategoryName:', categoryId); name = 'unknown'; } return name;} I would like to translate this texts - [low, medium, high, critical] using https://github.com/yahoo/react-intl. So I defined messages

I'm using React-Intl with webpack and I need the Intl shim to support Safari and IE, but I don't want to load it for browsers that already support the Intl spec.

MochaJS is a feature-rich JavaScript test framework running on Node.js, making it a popular choice for both backend and frontend testing. It's known for its flexibility and straightforward syntax, allowing for asynchronous testing and the use of any assertion library.

We use Jest Framework for testing. Jest is not a dogma, and, of course, in its place can be any other test runner, such as Mocha or Ava. Let's focus on tests. I'll provide a short example because I don’t want to waste your time. You can find the full version here. It's crucial to read the comments in the code below. Let's go!

JavaScript Popular tools for testing: Mocha, Jasmine, Unit JS, Jest

To execute your tests, you can create test scripts using popular testing frameworks like Mocha, Jasmine, or Jest. These frameworks provide a structured way to organize and run your tests, report results, and handle assertions.

⚗️ Mocha and Chai for testing

Testing frameworks like Jest, Mocha, and Jasmine are crucial for software development, ensuring code reliability and correctness. They offer features like test suites, test cases, assertions, and asynchronous testing support.
