Earlier in this series, we wrote unit tests for the DayViewModel
, the WeekViewModel
, and the WeekDayViewModel
structs. Writing those unit tests was fairly straightforward. Unit testing the RootViewModel
class is a bit more challenging for a number of reasons.
The RootViewModel
class asynchronously fetches the location of the device and weather data for a location. To unit test asynchronous operations, we need to take a different approach.
