Hi 

public void deleteITem()
{
String i=System.CurrentPageReference().getParameters().get('aid');
System.debug('/////'+i);
Integer k = 0;
boolean b = true;
for(InnerClass IP : IList)
{
System.debug('*************'+IP.uniqid);

if(IP.uniqid==Integer.valueOf(System.CurrentPageReference().getParameters().get('aid')))
{ 
b=false;
break;
}
k++;
}
if(!b)
{
IList.remove(k);
}
}

 am not covering the above code in the test class, plese look at this

Thanks in Advance
