Coverage reporting tool for The Go Programming Language
go install github.com/gozelle/gocov/gocov@latest
There are currently four gocov commands: test, convert, report and annotate.
Running gocov test [args...] will run go test [args...] with
an implicit -coverprofile added, and then output the result of
gocov convert with the profile.
Running gocov convert <coverprofile> will convert a coverage
profile generated by go tool cover to gocov's JSON interchange
format. For example:
go test -coverprofile=c.out
gocov convert c.out | gocov annotate -
Running gocov report <coverage.json> will generate a textual
report from the coverage data output by gocov convert. It is
assumed that the source code has not changed in between.
Output from gocov test is printed to stdout so users can
pipe the output to gocov report to view a summary of the test
coverage, for example: -
gocov test | gocov report
Running gocov annotate <coverage.json> <package[.receiver].function>
will generate a source listing of the specified function, annotating
it with coverage information, such as which lines have been missed.
