I wonder if there's any tool that can convert go test -coverprofile=cover.out into the formats that Jenkins can accept? I found some tools like go-junit-report and go2xunit, but they actually just convert output from go test -v, which is not the coverage report.
I want to know the detailed test coverage in Jenkins directly. Basically, I want to see the output from go tool cover -func=cover.out and go tool cover -html=cover.out in Jenkins webpage.
There are several go tools for converting coverage data from go test to Cobertura for Jenkins: gocover-cobertura, or gocov with gocov-xml.
You can use gocover-cobertura as follows:
$ go get github.com/t-yuki/gocover-cobertura
$ go test -coverprofile=cover.out example.com/demo/...
ok example.com/demo 0.008s coverage: 0.0% of statements
ok example.com/demo/cmd/demo 0.020s coverage: 23.4% of statements
$ gocover-cobertura < cover.out > coverage.xml
$ head coverage.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE coverage SYSTEM "http://cobertura.sourceforge.net/xml/coverage-04.dtd">
<coverage line-rate="0.35415787" branch-rate="0" version="" timestamp="1520609235359" lines-covered="839" lines-valid="2369" branches-covered="0" branches-valid="0" complexity="0">

Note that you'll need Go 1.10+ to run -coverprofile against multiple packages in one run.

This is what we need. Use Coberuta plugin to generate the coverage profile.
There isn't a dedicated plugin for Go coverage reports, nor really for generic code coverage.
For reports like this, I use the HTML Publisher Plugin to publish .html files created during a build.
