KEP05: CMD Utilities

[kensipe]

According to KEP-05:

The cmd package should provide conveniences for running arbitrary commands (i.e. shelling out) from Go code in integration tests.

Current functionality:

• Providing an Exec function that returns exit status, stdout and stderr

package cmd
func Exec(
  command string,
  arguments []string,
  environmentVariables map[string]string,
) (
  exitStatus int,
  stdout *bytes.Buffer,
  stderr *bytes.Buffer,
  error error,
)
