Lean what it means to decouple code, with a comparison of tightly-coupled and decoupled code in the demo application.
- [Instructor] Decouple your code.…You may have have heard it often,…but not really understood what it means.…Let's start with what coupling means…in the context of software architecture.…When components depend directly on other components…those components have to be in place to test that code.…Coupling is when a component depends on a component…it depends on a component.…They have to come together as a package.…Given some web request, it depends on authentication,…a database, maybe another web service, some business logic.…
All of these pieces are required…to return the result of the call.…Tightly coupled code means that all of these things…have to be in place to see if the action works.…This means, big complicated integration tests…with a lot of different outcomes.…The first step to writing unit tests…is to isolate dependencies from one another…so they can be tested and mocked out independently.…This is decoupling.…Code with significant dependencies…or more than one responsibility is hard to test.…
