java.lang.Object

org.jboss.byteman.contrib.bmunit.BMUnit

public class BMUnit
extends Object

Byteman Unit test manager class which provides support for loading and unloading scripts. This version assumes loads the agent as needed (unless inhibited -- see below) using System properties to control what hostname and port it uses for the socket. Other system properties can be used to configure operation of the load/unload operations.

Field Detail

LOAD_DIRECTORY

public static final String LOAD_DIRECTORY

System property which identifies the directory from which to start searching for rule script. If unset the current working directory of the test is used.

Constant Field Values

RESOURCE_LOAD_DIRECTORY

public static final String RESOURCE_LOAD_DIRECTORY

System property which identifies the resource load directory from which to start searching for rule script.

Constant Field Values

AGENT_PORT

public static final String AGENT_PORT

System property specifying the port to be used when starting the agent and when submitting rules to it. You can normally just use the default port.

Constant Field Values

AGENT_HOST

public static final String AGENT_HOST

System property specifying the host to be used when starting the agent and when submitting rules to it. You can normally just use the default host.

Constant Field Values

AGENT_POLICY

public static final String AGENT_POLICY

System property specifying whether to set a security policy when loading the agent.

Constant Field Values

AGENT_INHIBIT

public static final String AGENT_INHIBIT

System property which inhibits automatic loading of the agent. If you set this then you have to load the agent yourself using the Install API or ensure JUnit loads by forking a JVM and passing the necessary -javaagent options on the command line. You may also want to set this if you you have loaded the agent into a remote service in another JVM driven by your unit test.

VERBOSE

public static final String VERBOSE

System property which enables tracing of bmunit activity
