jest-ban-console

Ban console from being called in Jest tests.

How to use

First, install into your project:

$ npm install --save-dev jest-ban-console || yarn add --dev jest-ban-console

Then, ban console from individual tests:

import { jestBanConsole } from "jest-ban-console";

describe("your module", () => {
  jestBanConsole();
});

If you want to enforce this across all of your tests, run it in your setupTests.js or similar:

import { jestBanConsole } from "jest-ban-console";

jestBanConsole();
