Parameters:
help : Show usage.
repo-name : GitHub URL of repo to check in form "github.com/user/repo"
(equivalent to "--repo \$URL").
true : Specify as "true" if testing a specific branch, else assume a
PR branch (equivalent to "--all").
Notes:
- If no options are specified, all non-skipped tests will be run.
- Some required tools may be installed in \$GOPATH/bin, so you should ensure
that it is in your \$PATH.
Examples:
- Run all tests on a specific branch (stable or main) of kata-containers repo:
$ $script_name github.com/kata-containers/kata-containers true
- Auto-detect repository and run golang tests for current repository:
$ KATA_DEV_MODE=true $script_name --golang
- Run all tests on the kata-containers repository, forcing the tests to
consider all files, not just those changed by a PR branch:
$ $script_name github.com/kata-containers/kata-containers --all
