public class ReturnValue

extends java.lang.Object

The ReturnValue class allows a value to be setup which will then be returned upon a specific method call. If value.getValue() is called before value.setValue(value) the ReturnValue will raise an error warning that this value has not been set. If the required return value is null the return value can be set like this value.setValue(null) in this case calling value.getValue() will return null.

The advantage of this is provide better information to the user of a mock when interacting with third party code which may expect certain values to have been set.

e.g.

 private final ReturnValue value = new ReturnValue("value");

 public void setupValue(Integer value){
    value.setValue(value);
 }

 public Integer getValue(){
     return (Integer)value.getValue();
 }

Parameters:

name - the name used to identify the ReturnValue when an error is raised

Method Detail

getValue

public java.lang.Object getValue()

Returns:

the value set using setValue

Throws:

junit.framework.AssertionFailedError - throw if setValue has not been called

setValue

public void setValue(java.lang.Object value)

Parameters:

value - value to be returned by getValue. null can be use to force getValue to return null.

Returns:

the current value converted to a boolean

getIntValue

public int getIntValue()

Returns:

the current value converted to an int

setValue

public void setValue(int value)

Parameters:

value - value to be returned by getIntValue. Calling getValue after this method will return a Integer wrapper around the value.

setValue

public void setValue(long value)

Parameters:

value - value to be returned by getLongValue. Calling getValue after this method will return a Long wrapper around the value.

getLongValue

public long getLongValue()

Returns:

the current value converted to an long
