Detailed Description

Library for writing testcases for GNUnet.

It can start/stop one or more peers on a system; testing is responsible for managing private keys, ports and paths; it is a low-level library that does not support higher-level functions such as P2P connection, topology management or distributed testbed maintenance (those are provided by the Testbed service)

struct GNUNET_TESTING_System* GNUNET_TESTING_system_create ( const char *  testdir,
const char *  trusted_ip,
const char *  hostname,
const struct GNUNET_TESTING_SharedService shared_services 
)

Create a system handle.

There must only be one system handle per operating system. Uses a default range for allowed ports. Ports are still tested for availability.

Parameters
testdironly the directory name without any path. This is used for all service homes; the directory will be created in a temporary location depending on the underlying OS. This variable will be overridden with the value of the environmental variable GNUNET_TESTING_PREFIX, if it exists.
trusted_ipthe ip address which will be set as TRUSTED HOST in all service configurations generated to allow control connections from this ip. This can either be a single ip address or a network address in CIDR notation.
hostnamethe hostname of the system we are using for testing; NULL for localhost
shared_servicesNULL terminated array describing services that are to be shared among peers
Returns
handle to this system, NULL on error

Create a system handle.

There must only be one system handle per operating system. Use this function directly if multiple system objects are created for the same host (only really useful when testing — or to make the port range configureable).

Parameters
testdironly the directory name without any path. This is used for all service homes; the directory will be created in a temporary location depending on the underlying OS. This variable will be overridden with the value of the environmental variable GNUNET_TESTING_PREFIX, if it exists.
trusted_ipthe ip address which will be set as TRUSTED HOST in all service configurations generated to allow control connections from this ip. This can either be a single ip address or a network address in CIDR notation.

struct GNUNET_CRYPTO_EddsaPrivateKey* GNUNET_TESTING_hostkey_get ( const struct GNUNET_TESTING_System system,

)

Testing includes a number of pre-created hostkeys for faster peer startup.

This function can be used to access the n-th key of those pre-created hostkeys; note that these keys are ONLY useful for testing and not secure as the private keys are part of the public GNUnet source code.

This is primarily a helper function used internally by GNUNET_TESTING_peer_configure().

Parameters
systemthe testing system handle
key_numberdesired pre-created hostkey to obtain
idset to the peer's identity (hash of the public key; if NULL, GNUNET_SYSERR is returned immediately
Returns
NULL on error (not enough keys)

◆ GNUNET_TESTING_configuration_create()

int GNUNET_TESTING_configuration_create ( struct GNUNET_TESTING_System system,
struct GNUNET_CONFIGURATION_Handle cfg 
)

Create a new configuration using the given configuration as a template; ports and paths will be modified to select available ports on the local system.

The default configuration will be available in PATHS section under the option DEFAULTCONFIG after the call. SERVICE_HOME is also set in PATHS section to the temporary directory specific to this configuration. If we run out of "*port" numbers, return GNUNET_SYSERR.

This is primarily a helper function used internally by GNUNET_TESTING_peer_configure().

Parameters
systemsystem to use to coordinate resource usage
cfgtemplate configuration to update
Returns
GNUNET_OK on success, GNUNET_SYSERR on error - the configuration will be incomplete and should not be used there upon

◆ GNUNET_TESTING_peer_stop()

int GNUNET_TESTING_peer_stop ( struct GNUNET_TESTING_Peer peer)

Stop the peer.

This call is blocking as it kills the peer's main ARM process by sending a SIGTERM and waits on it. For asynchronous shutdown of peer, see GNUNET_TESTING_peer_stop_async().

Parameters
peerpeer to stop
Returns
GNUNET_OK on success, GNUNET_SYSERR on error (i.e. peer not running)
Parameters
peerpeer to stop
Returns
GNUNET_OK on success, GNUNET_SYSERR on error

Here is the caller graph for this function:

◆ GNUNET_TESTING_get_testname_from_underscore()

char* GNUNET_TESTING_get_testname_from_underscore ( const char *  argv0)

Sometimes we use the binary name to determine which specific test to run.

In those cases, the string after the last "_" in 'argv[0]' specifies a string that determines the configuration file or plugin to use.

This function returns the respective substring, taking care of issues such as binaries ending in '.exe' on W32.

Parameters
argv0the name of the binary
Returns
string between the last '_' and the '.exe' (or the end of the string), NULL if argv0 has no '_'
