Automatic create Jest config for Angular projects

It's very convenient to testing our applications with Angular and Jest now.

Quick start

$ npm install @angular-ru/jest-utils -D

Create jest.config.js

const { createTsJestConfig } = require('@angular-ru/jest-utils');

module.exports = createTsJestConfig({
    tsConfig: './tsconfig.json',
    jestConfig: {
        rootDir: '.',
        displayName: 'My Angular App',
        testMatch: ['<rootDir>/tests/**/*.spec.ts'],
        collectCoverageFrom: ['<rootDir>/src/app/**/*.ts']
    }
});

$ jest --config jest.config.js --coverage
