Question

我有一个规范

final Join<MovieEntity, MovieOtherTitleEntity> listOtherTitles = root.join(MovieEntity_.otherTitles);
        final List<Predicate> orPredicates =
                Stream.of(title)
                        .map(t -> cb.and(
                                cb.like(cb.upper(listOtherTitles.get(MovieOtherTitleEntity_.title)), "%" + t.toUpperCase() + "%"),
                                cb.equal(listOtherTitles.get(MovieOtherTitleEntity_.status), DataStatus.ACCEPTED)
                                )
                        )
                        .collect(Collectors.toList());

我为此代码https://pastebin.com/VZd4c0VM创建了一个测试但是，在测试期间，他抛出错误

    org.mockito.exceptions.verification.TooManyActualInvocations: 
criteriaBuilder.upper(null);

关键是MovieEntity实体有一个实体列表MovieOtherTitlee。每个MovieOtherTitlee都有一个Title和Status字段，用于搜索MovieEntity实体对象。我想为此代码编写UnitTest，但我有一个问题，因为它非常复杂。

如何测试谓词规范
