func GetAvailableLocalNetworkAddress(tb testing.TB, network string) string

GetAvailableLocalNetworkAddress finds an available local port on specified network and returns an endpoint describing it. The port is available for opening when this function returns provided that there is no race by some other code to grab the same port immediately.

func SetFeatureGateForTest ¶ added in v0.55.0

func SetFeatureGateForTest(tb testing.TB, gate *featuregate.Gate, enabled bool) func()

Force the state of feature gate for a test usage: defer SetFeatureGateForTest("gateName", true)()

func TempDir ¶ added in v0.136.0

func TempDir(tb testing.TB) string

TempDir creates a temporary directory in a safe way. On Linux, it just calls tb.TempDir.

On Windows, it uses os.MkdirTemp to create directory since t.TempDir results in an error during cleanup in scoped-tests, possibly due to an interaction with the -count argument in `go test`. It does not do any cleanup (i.e. the directory is left on the filesystem). Prefer using tb.TempDir directly if possible.
