Functions

func Execute

func Execute(cmdLine string, args ...interface{}) (string, error)

Execute executes the command generated by fmt.Sprintf(cmdLine, args...) and returns its output.

func Retry

func Retry(command model.Cmd, expectedResult string, timeout int) bool

Retry runs the provided <cmd> repeatedly, once a second up to the supplied <timeout> until the <cmd> result contains the <expectedResult> An example use of this utility would be curl-ing a url and waiting until the response code matches the expected response.

func Start

func Start(cmdLine string, user *model.User, args ...interface{}) (*gexec.Session, error)

Start executes the provided command (often a `deis` command of some sort) as the specified user (by selecting the corresponding profile). Optional arguments may also be supplied that will be substituted into the provided command using fmt.Sprintf(...).

func StartCmd

func StartCmd(command model.Cmd) (*gexec.Session, error)

StartCmd executes the provided model.Command. It is used primarily by the Start function (above), but is also used directly in scenarios where tests must execute fine-grained control over the environment in which the command will be executed.
