Cov is a rudimentary code coverage tool.
go tool cov [-lsv] [-g substring] [-m minlines] [6.out args]
Given a command to run, it runs the command while tracking which
sections of code have been executed. When the command finishes,
cov prints the line numbers of sections of code in the binary that
were not executed. With no arguments it assumes the command "6.out".
The options are:
print full path names instead of paths relative to the current directory
show the source code that didn't execute, in addition to the line numbers.
print debugging information during the run.
-g substring
restrict the coverage analysis to functions or files whose names contain substring
-m minlines
only report uncovered sections of code larger than minlines lines
The program is the same for all architectures: 386, amd64, and arm.
