this.logger.error(new Error('hello error level'));
this.logger.debug('hello debug level');

debug log is disabled by default, you could enable it by:

• command line argv: --verbose
• process env: DEBUG=CLI
• programmatically: logger.level = 'DEBUG'

const answers = await this.prompt([
  {
    type: 'input',
    name: 'name',
    message: 'What is your name:',
  }, {
    type: 'list',
    name: 'type',
    message: 'Choose a boilerplate:',
    choices: [ 'empty', 'simple', 'plugin', 'framework' ],
  },
]);

this.logger.info(answers);

Unit Testing

Use coffee :

const coffee = require('coffee');

describe('test/index.test.js', () => {
  it('should work', () => {
    return coffee.fork('/path/to/cli')
      // .debug()
      .waitForPrompt()
      .write('tz\n')
      .writeKey('DOWN', 'ENTER')
      .write('this is a desc\n')
      .expect('stdout', /{ name: 'tz', type: 'simple' }/)
      .expect('stdout', /{ description: 'this is a desc' }/)
      .expect('code', 0)
      .end();
  });
