| Cover is a program for analyzing the coverage profiles generated by |
| 'go test -coverprofile=cover.out'. |
| |
| Cover is also used by 'go test -cover' to rewrite the source code with |
| annotations to track which parts of each function are executed. |
| It operates on one Go source file at a time, computing approximate |
| basic block information by studying the source. It is thus more portable |
| than binary-rewriting coverage tools, but also a little less capable. |
| For instance, it does not probe inside && and || expressions, and can |
| be mildly confused by single statements with multiple function literals. |
| |
| When computing coverage of a package that uses cgo, the cover tool |
| must be applied to the output of cgo preprocessing, not the input, |
| because cover deletes comments that are significant to cgo. |
| |
| For usage information, please see: |
| |
| go help testflag |
| go tool cover -help |
