Because you use new Twilio() you'd have to mock the twilio package using jest.mock. I'd rather suggest making that a provider so you can mock the provided object rather than the constructor

thanks @civic narwhal
to make it a provider i would have to setup a twilioModule right?
civic narwhal
Not necessarily. If you plan to use it in multiple locations I would though
wanton sleet
what would be the other way, if i dont make it a module?
civic narwhal
Just add it to the current module's providers
wanton sleet
Like new TwilioClient()
civic narwhal
{
provide: 'TWILIO_CLIENT',
inject: [TWILIO_CLIENT_OPTIONS_TOKEN],
useFactory: (options) => new Twilio(options)m
}
Assuming that the options have a dedicated token
civic narwhal
what does dedicated token mean?
An injection token. If they don't you could just inject the ConfigService instead and pull the values from there

ok makes sense.. this would be easier to test then!
