Interface EphemeralPortRangeDetector

All Known Implementing Classes:
FixedIANAPortRange, LinuxEphemeralPortRangeDetector, OlderWindowsVersionEphemeralPortDetector
public interface EphemeralPortRangeDetector
Identifies the ephemeral port range for a given environment.

When trying to locate a "random" free port, it is important to not allocate within the ephemeral range, since these can be allocated at any time, and the probability of race conditions increases as the number of recently used ports increases, something which is quite common when running the webdriver tests.
