What is the primary purpose of unit testing in Go?

  • To ensure the code is bug-free.
  • To test the entire application.
  • To verify that external dependencies are functioning.
  • To check code coverage.
The primary purpose of unit testing in Go is to ensure that individual units of code (such as functions or methods) work correctly and are free of bugs. Unit tests focus on isolating and testing a specific piece of code in isolation from the rest of the application, helping to catch and fix bugs early in the development process. It's not about testing the entire application or checking code coverage; those are goals of other types of testing.
