如何理解这个Go makefile？

Question

COVERPROFILE=cover.out

default: test

cover:
    go test -coverprofile=$(COVERPROFILE) .
    go tool cover -html=$(COVERPROFILE)
    rm $(COVERPROFILE)

dependencies:
    go get -d .

test:
    go test -i ./...
    go test -v ./...

.PHONY: coverage dependencies test

I don't understand this golang makefile. Is there any tutorial for golang makefiles? I searched Google and didn't find any complete one. For example, I don't see any explanation for what is "cover," etc.

Answer 1

That is just a plain make file and not even well written.

1. running just make will execute the commands under test
2. make dependencies will download all the dependencies of the current packages
3. make cover will do coverage testing and output an html file
