Add Go test plugin

[ninjinkun]

Requirement

Install go-junit-report

go get -u github.com/jstemmer/go-junit-report

Usage

subset

subset command receives test names from stdin

go test -list . | launchable subset --name '#123' go_test > subset.txt
go test -run $(cat subset.txt)

record tests

record tests command read JUnit XML files.

go test -v 2>&1 | go-junit-report >  report.xml # convert output via go-junit-report 
launchable record tests --name '#123' go_test .

Disucussion

Should the plugin command name be go_test or go-test?

Exciting!!

@kohsuke @awilkes I found one more discussion point. This subset command outputs with white spaces such as ExampleTest1 ExampleTest2 ExampleTest3. However go test -run receive regexp only. It means customers need to convert the output to ^ExampleTest1$ |^ExampleTest2$|^ExampleTest3$ via shell script (see Usage on the PR I updated). Do you think we need to integrate the conversion into the CLI?

[ninjinkun]

I changed subset output to regexp ^ExampleTest1$ |^ExampleTest2$|^ExampleTest3$.

The less the users have to do the better, so I think this makes sense 👍
