Go Coverage over multiple package 和 Gitlab Coverage Badge

Question

我正在尝试为我的 gitlab 项目显示准确的覆盖率徽章。

问题是我有几个包，在 gitlab-ci.yml，我运行

go test $(go list ./... | grep -v /vendor/) -v -coverprofile .testCoverage.txt

我的输出是这样的:

$ go test -coverprofile=coverage.txt -covermode=atomic ./...
 ok     gitlab.com/[MASKED]/pam 10.333s coverage: 17.2% of statements
 ok     gitlab.com/[MASKED]/pam/acquisition 0.004s  coverage: 57.7% of statements
 ok     gitlab.com/[MASKED]/pam/acquisition/api 0.005s  coverage: 72.1% of statements
 ok     gitlab.com/[MASKED]/pam/acquisition/ftp 24.936s coverage: 73.1% of statements
 ok     gitlab.com/[MASKED]/pam/repartition 0.004s  coverage: 90.1% of statements

我在 Gitlab 中的测试覆盖率解析正则表达式是:

^coverage:\s(\d+(?:\.\d+)?%)

如果我检查 .testCoverage，我会得到很多这样的行:

 gitlab.com/[MASKED]/pam/repartition/repartition.go:54.33,56.5 1 1

所以，当它只是最后一个包的覆盖率时，它给了我一个 90.1% 的结果。

我该怎么做？

Answer 1

根据this answer ,

我只需要另一个命令:

go tool cover -func profile.cov

这会给你结果:

✗ go tool cover -func profile.cov

gitlab.com/[MASKED]/pam/acquisition/acquisition.go:17:                       FetchAll                        0.0%
gitlab.com/[MASKED]/pam/acquisition/acquisition.go:32:                       TransformData                   100.0%
gitlab.com/[MASKED]/pam/acquisition/acquisition_mocks.go:13:                 FetchMeters                     0.0%
gitlab.com/[MASKED]/pam/repartition/repartition.go:102:                      GroupMetersByOperation          100.0%
gitlab.com/[MASKED]/pam/repartition/repartition.go:111:                      SetProrataRedistributed         71.4%
total:                                                                          (statements)                    68.7%

在 gitlab 中，你可以更改正则表达式:

^coverage:\s(\d+(?:\.\d+)?%)

由

\(statements\)(?:\s+)?(\d+(?:\.\d+)?%)

现在，如果您有模拟，覆盖范围将包括它们，因此您必须在此 answer 之后删除它们:

go test . -coverprofile profile.cov.tmp
cat profile.cov.tmp | grep -v "_mocks.go" > cover.out
tool cover -func profile.cov

当然，你所有的模拟都应该放在后缀为:_mocks.go

的文件中

它应该可以工作。
