Migrate to MobX i18n since v4.
If you are looking for a simple alternative of Mocha or Jest, just use these Test Utility methods with ts-node:
npx ts-node index.spec.ts
index.spec.ts
import { describe, it } from 'web-utility';
class App {
name = 'test';
static create() {
return new App();
}
}
describe('My module', async () => {
const app = await it('should create an App object', async expect => {
const app = App.create();
expect(app instanceof App);
return app;
});
await it('should init an App name', expect => {
expect(app.name === 'test');
});
});
