 Simple test case:
{code:java}
Expression exp = ExpressionFactory.exp("(false and true) and true");
Expression transformed = exp.transform(node -> {
    if(node instanceof ASTFalse) {
        return Expression.PRUNED_NODE;
    }
    return node;
});
assertEquals("true and true", transformed.toString());
{code}
