You're working on a project with a team, and you want to enforce a convention for naming test functions. How would you achieve this in Go unit testing?

  • Document the naming convention in the project's README
  • Encourage team members to manually adhere to the naming convention
  • Implement a custom script to rename test functions according to the convention
  • Use a linter tool to check for naming conventions
In Go, you can enforce a convention for naming test functions by using a linter tool such as golint or golangci-lint. These tools can analyze the codebase and report any deviations from the naming convention specified for test functions. Documenting the naming convention in the project's README is helpful for informing team members about the convention, but it doesn't actively enforce adherence to it. Implementing a custom script to rename test functions may be error-prone and unnecessary when linter tools can perform this task more reliably. Encouraging team members to manually adhere to the naming convention relies on human effort and may result in inconsistencies. Therefore, using a linter tool is the most effective approach to enforce naming conventions for test functions in Go.
