Go files must be formatted with gofmt, and the tests will check that this is the case. If the files are not correctly formatted, the tests will fail.
You can format your files by running:
gofmt -w -s .
Run the unit tests from within the go directory with:
go test . -v
To also run the benchmark tests, run:
go test -bench=. . -v
