'mockito a List<Predicate<String>> to always return true

I have a list<Predicate> which is a private field of a class, and this field will be used to filter lines of data.

I would like to test my class with mocking the list<Predicate> by making it always true/false.

public class T {
     private final List<Predicate<String>> filters;
     
     public void run(){
         ...
         while ((line = input.readLine()) != null) {
              if (filters.stream().allMatch(filter -> filter.test(line))) {
               ....
}}}

I am wondering how to mock this field filters in tests. Thanks!
