Modifier and Type	Method and Description
static void	analyzeDnsResolution(String host) Force collecting DNS info, without failing if errors
static String[]	collectExternalServiceInfo(ExternalServiceInfo remoteHostInfo, int remotePort) If there is a mock server assigned for the given hostname, core will try to check the active status and if not active it will update the respective port and initiate the server.

Field Detail

canonicalLocalHostname

public static final String canonicalLocalHostname

A local address created based on a direct IP address like 127.0.0.1 can result in a reverse-lookup for hostname in something different than "localhost". This could be for example "kubernetes.docker.internal" if you have Docker installed.

Constructor Detail

ExternalServiceUtils

public ExternalServiceUtils()

Method Detail

isValidIP

public static boolean isValidIP(String s)

Check if string literal is a valid v4 or v6 IP address

analyzeDnsResolution

public static void analyzeDnsResolution(String host)

Force collecting DNS info, without failing if errors

collectExternalServiceInfo

public static String[] collectExternalServiceInfo(ExternalServiceInfo remoteHostInfo,
                                                  int remotePort)

If there is a mock server assigned for the given hostname, core will try to check the active status and if not active it will update the respective port and initiate the server. On the next, attempt SUT will connect to the active WireMock server.

Parameters:

remoteHostInfo - is the host info collected from the SUT

remotePort - is the port employed by the SUT

Returns:

redirected an array with two elements

skipHostnameOrIp

public static boolean skipHostnameOrIp(String hostname)

skip method replacement for some hostname. For example, we want to avoid skipping local addresses, because things like Databases and other services like Kafka could be running there. Further, those things could be running in Docker, so should skip Docker as well

skipHostname

public static boolean skipHostname(String hostname)

inferPort

public static int inferPort(int port,
                            String protocol)

Unless the port number is specified in a URL, the default will be -1. This indicates that the port should be assigned according to the protocol. Since the URLConnection openConnection is an abstract, this assignment will be handled under the respective implementation. Here it's manually handled assuming these default will never change.

Parameters:

port -

protocol -

Returns:

getReplacedURL

public static URL getReplacedURL(URL url)
