Testing

No need to test your logic through the UI or using React with libraries like react-testing-library or react-hook-testing-library.

You can simply test your logic with Jest, pretty quickly and easily develop some features using test driven development (TDD)

// counter.test.ts
import { createCore } from 'cortex/setup/setup';

describe('counter', () => {
  it('should be incremented', () => {
    const core = createCore();
    const service = core.getService('counter');

    expect(service.state.count).toBe(0)

    service.increment()
    expect(service.state.count).toBe(1)

    service.increment()
    expect(service.state.count).toBe(2)
  })

  it('should be decremented', () => {
    const core = createCore();
    const service = core.getService('counter');

    service.state.count = 5

    service.decrement()
    expect(service.state.count).toBe(4)

    service.decrement()
    expect(service.state.count).toBe(3)
  })

  it('should not be decremented at a lower value than 0', () => {
    const core = createCore();
    const service = core.getService('counter');

    service.state.count = 1

    service.decrement()
    expect(service.state.count).toBe(0)

    service.decrement()
    expect(service.state.count).toBe(0)
  })
})
