Class InstrumentedClass

java.lang.Object

org.jboss.byteman.contrib.dtest.InstrumentedClass

All Implemented Interfaces:

Remote, RemoteInterface

public class InstrumentedClass
extends Object
implements RemoteInterface

InstrumentedClass instances serve two purposes: Internally to the framework they provide a communication endpoint for receiving information from the remote, Byteman instrumented code execution. To the framework user, they provide utility methods for verifying expectations relating to that remote execution e.g. the number of method calls made.

Method Summary

Methods

Modifier and Type	Method and Description
void	assertKnownInstances(int count) Checks that the number of known, distinct object instances of this class is as stated.
void	assertMethodCallCount(String message, String methodName, CallCount callCount) Checks that the number of known invocations of the given method falls within the specified range for each known instances of the class.
void	assertMethodCalled(String methodName) Checks that the given method has been called at least once on each known instance of the class.
void	assertMethodNotCalled(String methodName) Checks that the given method has not been seen to be called on any known instance of the class.
Set<InstrumentedInstance>	getInstances() Returns the set of known instances of the class.

Method Detail

trace

public void trace(String methodName,
         Object[] args)
           throws RemoteException

Receiving side of the remote communication between the test code and the BytemanTestHelper.

Specified by:

trace in interface RemoteInterface

Parameters:

methodName - the method name that was traced.

args - the arguments to the method invocation, in String form.

Throws:

RemoteException - in case of communication failure.

BytemanTestHelper.remoteTrace(String, String, Object[])

getInstances

public Set<InstrumentedInstance> getInstances()

Returns the set of known instances of the class.

Returns:

a Set of Objects representing instances of the class.

assertKnownInstances

public void assertKnownInstances(int count)

Checks that the number of known, distinct object instances of this class is as stated.

Parameters:

count - the expected number of instances of the class.

assertMethodCallCount

public void assertMethodCallCount(String message,
                         String methodName,
                         CallCount callCount)

Checks that the number of known invocations of the given method falls within the specified range for each known instances of the class.

Parameters:

message - the message to print in case of assertion failure.

methodName - the method name to look for.

callCount - the expected range for the invocation count.

assertMethodCalled

public void assertMethodCalled(String methodName)

Checks that the given method has been called at least once on each known instance of the class. Uses junit internally, hence expect the normal exception throwing in case of failure.

Parameters:

methodName - the method name to look for.

assertMethodNotCalled

public void assertMethodNotCalled(String methodName)

Checks that the given method has not been seen to be called on any known instance of the class. Uses junit internally, hence expect the normal exception throwing in case of failure.

Parameters:

methodName - the method name to look for.
