Support JUnit output format

[iwata]

I'm using CircleCI.
It can show Test Summary section.
But in order to display the summary, it is necessary to output in JUnit format.

hi!
pull requests are welcome but I suggest using code climate or golangci.com or hound ci or similar: they allow to see linters warnings inline like a code review

@iwata what exactly would you like golangci to output in a JUnit file? golangci does not execute tests. You could use gotestsum for that: https://github.com/gotestyourself/gotestsum

golangci does not execute tests.

I know.
I want to output the result of this linter in JUnit format looks like ESLint.

I think this is added in 1.17?

@howardjohn yeah, seems to be true. It seems that JUnit format support was added in #557 and fixed in #632

True. Closing ✅

Hello,
It seems that the generated output is not valid, according to the Jenkins Junit XSD (https://github.com/jenkinsci/xunit-plugin/blob/master/src/main/resources/org/jenkinsci/plugins/xunit/types/model/xsd/junit-10.xsd).
For example, the attributes tests, failures and errors are missing.
