Functions

func CheckSkip 

func CheckSkip(t *testing.T)

CheckSkip marks a test to be skipped unless the integration test has been specifically requested using the -run flag.

func GetFreePort 

func GetFreePort() (int, error)

GetFreePort attempts to get a free port. This involves creating a bind and then immediately dropping it and so it's ever so slightly flakey.

Types

type CachePreTestFn 

type CachePreTestFn func(t testing.TB, ctx context.Context, testID string, vars *CacheTestConfigVars)
