Functions ¶

func Run ¶

func Run(dut DUT) error

Types ¶

type DUT ¶

type DUT interface {
	// Bootstrap starts a DUT and returns the collected DUTInfo and a function
	// for the caller to call to wait for the completion of the DUT.
	Bootstrap(ctx context.Context) (testbench.DUTInfo, func() error, error)
	// Cleanup stops the DUT and cleans up the resources being used.
	Cleanup()
}

DUT is an interface for different platforms of DUTs.

type Ifaces ¶

type Ifaces struct {
	// Ctrl is the name of the control interface.
	Ctrl string
	// Test is the name of the test interface.
	Test string
}

Ifaces describe the names of the interfaces on DUT.

func Init ¶

func Init(fs *flag.FlagSet) (Ifaces, error)
