Question

You are to develop a set ofunit testcasesfor the following code block.Note that the code below 5 may contain some faults. The test cases you write should catch these faults and any others that might arise as the code evolves.

Write at-least 5 tests, make sure that your tests cover and test evert aspect of the code.

public class AccumValue {
private int value;
public AccumValue (int init){ value = init; }
/**
* Computes a new accumulation value from the values in vs up to limit
* @returns true if value changed, false otherwise.
* /
public boolean calcAccum ( int limit, AccumValue[] vs ){
int[] array = new int[limit];
if( array.length < limit )
return false;
buildarray(array, vs);
int tmp=0;
for( int s: array )
tmp += s;
int old = value;
value = tmp;
return old != value;
}
protected void buildArray( int[] array, AccumValue[] vs ){
for( int i=0 ; ikarray.length ; ++i )
array[i] = vs[i].getValue();
}
public int getValue (){ return value; }
}
