Functions ¶

func DumpDir ¶

func DumpDir(t *testing.T, root string)

DumpDir will log out all of the contents of the provided directory to testing logger.

Use this in a defer statement within tests that may allocate and exercise a temporary directory. Immensely useful for sanity checking and debugging failing tests.

One should still test that contents are as expected. This is only a visual tool to assist when things don't go your way.

func NewLoopback ¶

func NewLoopback(size int64) (string, func() error, error)

NewLoopback creates a loopback device, and returns its device name (/dev/loopX), and its clean-up function.

func RequiresRoot ¶

func RequiresRoot(t testing.TB)

RequiresRoot skips tests that require root, unless the test.root flag has been set

func RequiresRootM ¶

func RequiresRootM()

RequiresRootM is similar to RequiresRoot but intended to be called from *testing.M.

func Unmount ¶

func Unmount(t *testing.T, mountPoint string)

Unmount unmounts a given mountPoint and sets t.Error if it fails
