The tool is designed to be a lightweight solution capable of checking
whether a file is correctly formatted or not based on go fmt output.
Unfortunately, other go commands such as go vet are better suited to
inherit from the RepositoryTool, as they require the ability to check
entire packages to properly test and vet files.

Manual testing was done to confirm that go fmt is working correctly.
