在AssertJ中，如果您使用断言描述，您可以打印它们或使用您注册的任何使用者。

示例：

// initialize the description consumer
final StringBuilder descriptionReportBuilder = new StringBuilder(String.format("Assertions:%n"));
Consumer<Description> descriptionConsumer = desc -> descriptionReportBuilder.append(String.format("-- %s%n", desc));

// use the description consumer for any following assertions descriptions.
Assertions.setDescriptionConsumer(descriptionConsumer);

// execute some assertions
TolkienCharacter frodo = new TolkienCharacter("Frodo", 33, Race.HOBBIT);
assertThat(frodo.getName()).as("check name")
                          .isEqualTo("Frodo");
assertThat(frodo.getAge()).as("check age")
                          .isEqualTo(33);

// get the report
String descriptionReport = descriptionReportBuilder.toString();

将打印此报告：

Assertions:
-- check name
-- check age
