Functions

func GetExitCodeForRunCommandError

func GetExitCodeForRunCommandError(err error) (int, error)

GetExitCodeForRunCommandError tries to read the exit code for the error object returned from running a shell command. This is a bit tricky to do in a way that works across platforms.

func RunCommand

func RunCommand(t *testing.T, command Command)

RunCommand runs a shell command and redirects its stdout and stderr to the stdout of the atomic script itself.

func RunCommandAndGetOutput

func RunCommandAndGetOutput(t *testing.T, command Command) string

RunCommandAndGetOutput runs a shell command and returns its stdout and stderr as a string. The stdout and stderr of that command will also be printed to the stdout and stderr of this Go program to make debugging easier.

func RunCommandAndGetOutputE

func RunCommandAndGetOutputE(t *testing.T, command Command) (string, error)

RunCommandAndGetOutputE runs a shell command and returns its stdout and stderr as a string. The stdout and stderr of that command will also be printed to the stdout and stderr of this Go program to make debugging easier.

func RunCommandAndGetStdOut

func RunCommandAndGetStdOut(t *testing.T, command Command) string

RunCommandAndGetStdOut runs a shell command and returns solely its stdout (but not stderr) as a string. The stdout and stderr of that command will also be printed to the stdout and stderr of this Go program to make debugging easier. If there are any errors, fail the test.

func RunCommandAndGetStdOutE

func RunCommandAndGetStdOutE(t *testing.T, command Command) (string, error)

RunCommandAndGetStdOutE runs a shell command and returns solely its stdout (but not stderr) as a string. The stdout and stderr of that command will also be printed to the stdout and stderr of this Go program to make debugging easier.

func RunCommandE

func RunCommandE(t *testing.T, command Command) error

RunCommandE runs a shell command and redirects its stdout and stderr to the stdout of the atomic script itself.

Types

type Command

type Command struct {
	Command           string            // The command to run
	Args              []string          // The args to pass to the command
	WorkingDir        string            // The working directory
	Env               map[string]string // Additional environment variables to set
	OutputMaxLineSize int               // The max line size of stdout and stderr (in bytes)
}

Command is a simpler struct for defining commands than Go's built-in Cmd.
