Consider using named constants or the field names to make the test more maintainable: `predicateBuilder.greaterThan("id", 1000L)` and `predicateBuilder.isNotNull("data")`. ```suggestion Predicate filter1 = predicateBuilder.greaterThan("id", 1000L); // id > 1000 Predicate filter2 = predicateBuilder.isNotNull("data"); // data is not null ``` -- This is an automated message from the Apache Git Service.
