There seems to have been a lot of talk around me lately in relation to “dev boxes” and “testing on staging”.
After unsuccessfully trying to convince folks of why I think this is a bad idea from both an engineering and business perspective I decided it was time to talk code.
In this repository I am hoping to show:
- How an external service calls can be properly encapsulated
- How different tests can be used to achieve different outcomes:
- Testing only the local package code in complete isolation from the external service
- Testing the external service fulfils expectations
- Testing the local package code handles external service failures (without needing to orchestrate the external service)
- How all of the above test types can be easily automated in order to prevent regression (for your service and the external service)
- How providing mocks from a package can help the users of the package test how their code interacts with your package
Enjoy!
