Act-Master-test-utils

ActTest - is a class that helps write tests for act-master.

ActTest - is a singleton class with static methods.

To write tests, use the method ActTest.getInstance(options?: ActMasterOptions).

It creates an instance of the act-master class, which can be easily used afterwards.

Example:

default configuration for examples

// Basic part, same for all examples

import { ActTest } from 'act-master-test-utils';

const $act = ActTest.getInstance();

beforeEach(() => {
  ActTest.resetAll();
});
// ...

// ... base settings

it('Example result', async () => {
  const action: ActMasterAction = {
    name: 'SomeName',
    exec() {
      return 42;
    }
  }

  $act.addActions([action]);

  await $act.exec('SomeName');

  expect(ActTest.getLastResult()).toBe(42);
});

You can also call some event and check your subscription.

// ... base settings

it('Example check subscription', async () => {
  const action: ActMasterAction = {
    name: 'SomeName',
    exec() {
      return 42;
    }
  }

  $act.addActions([action]);

  const mockFn = jest.fn();

  $act.subscribe('SomeName', mockFn);

  await ActTest.exec('SomeName');

  expect(mockFn).toBeCalledTimes(1);
});
