Difference between differents test-flags of go test
问题
我计划在Go中运行我的Cucumber测试（使用Godog），并想出了以下可能的测试命令。有人可以指出这些命令之间的区别吗？哪种方式被推荐使用，每种覆盖模式的用例是什么？
go test -test.v -test.run ^TestFeatures$ -coverpkg=../... -coverprofile=coverage.out -race
go test -test.v -test.run ^TestFeatures$ -coverpkg=../... -coverprofile=coverage1.out -covermode=set
go test -test.v -test.run ^TestFeatures$ -coverpkg=../... -coverprofile=coverage2.out -covermode=atomic
go test -test.v -test.run ^TestFeatures$ -coverpkg=../... -coverprofile=coverage3.out
go test -test.v -test.run ^TestFeatures$ -coverpkg=../... -coverprofile=coverage4.out
PS：对于GO的新手表示抱歉 
英文:
I am planning to run my Cucumber test in go (using Godog) & I came up with the following possibility of commands to run my tests.
Can someone point out the differences here? What is the recommended way & what's the use-case of each cover mode etc?
go test -test.v -test.run ^TestFeatures$ -coverpkg=../... -coverprofile=coverage.out -race
go test -test.v -test.run ^TestFeatures$ -coverpkg=../... -coverprofile=coverage1.out -covermode=set
go test -test.v -test.run ^TestFeatures$ -coverpkg=../... -coverprofile=coverage2.out -covermode=atomic
go test -test.v -test.run ^TestFeatures$ -coverpkg=../... -coverprofile=coverage3.out
go test -test.v -test.run ^TestFeatures$ -coverpkg=../... -coverprofile=coverage4.out
PS: Apologies for being a noob in GO

这在 GO 博客上有解答：https://go.dev/blog/cover#heat-maps：
- set：每个语句是否执行？
- count：每个语句执行了多少次？
- atomic：类似于 count，但在并行程序中精确计数。
英文:
This is answered on the GO blog: https://go.dev/blog/cover#heat-maps:
> - set: did each statement run?
> - count: how many times did each statement run?
> - atomic: like count, but counts precisely in parallel programs
