### Question:
ApplicationEntity extends BaseEntity { public void setConfigs(@Nullable final Set<FileEntity> configs) { this.configs.clear(); if (configs != null) { this.configs.addAll(configs); } } ApplicationEntity(); Optional<String> getType(); void setConfigs(@Nullable final Set<FileEntity> configs); void setDependencies(@Nullable final Set<FileEntity> dependencies); void setTags(@Nullable final Set<TagEntity> tags); @Override boolean equals(final Object o); @Override int hashCode(); static final String COMMANDS_ENTITY_GRAPH; static final String COMMANDS_DTO_ENTITY_GRAPH; static final String DTO_ENTITY_GRAPH; }### Answer:
@Test void testSetConfigs() { final Set<FileEntity> configs = Sets.newHashSet(new FileEntity("s3: this.a.setConfigs(configs); Assertions.assertThat(this.a.getConfigs()).isEqualTo(configs); this.a.setConfigs(null); Assertions.assertThat(this.a.getConfigs()).isEmpty(); }
