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 -D

Create jest.config.js

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

module.exports = createTsJestConfig({
    tsConfig: '<rootDir>/tsconfig.spec.json',
    jestConfig: {
        rootDir: __dirname, // or another path
        testMatch: ['<rootDir>/tests/**/*.spec.ts'],
        coverageDirectory: '<rootDir>/coverage/my-app',
        setupFilesAfterEnv: ['<rootDir>/tests/setup-jest.ts'],
        modulePathIgnorePatterns: ['<rootDir>/dist/@my-scope'],
        cacheDirectory: '<rootDir>/node_modules/.cache/jest',
        collectCoverageFrom: ['<rootDir>/**/*.ts', '!<rootDir>/**/*.spec.ts']
    }
});

$ jest --config jest.config.js
