软件介绍

AssertJ 是 JAVA 的流畅断言库。

示例代码：

// unique entry point to get access to all assertThat methods and utility methods (e.g. entry) import static org.assertj.core.api.Assertions.*; 
// common assertions assertThat(frodo.getName()).isEqualTo("Frodo");
assertThat(frodo).isNotEqualTo(sauron)
                 .isIn(fellowshipOfTheRing); 
// String specific assertions assertThat(frodo.getName()).startsWith("Fro")
                           .endsWith("do")
                           .isEqualToIgnoringCase("frodo"); 
// collection specific assertions assertThat(fellowshipOfTheRing).hasSize(9)
                               .contains(frodo, sam)
                               .doesNotContain(sauron); 
// using extracting magical feature to check fellowshipOfTheRing characters name :) assertThat(fellowshipOfTheRing).extracting("name").contains("Boromir", "Gandalf", "Frodo", "Legolas")
                                                  .doesNotContain("Sauron", "Elrond"); 
// map specific assertions, ringBearers initialized with the elves rings and the one ring bearers. assertThat(ringBearers).hasSize(4)
                       .contains(entry(oneRing, frodo), entry(nenya, galadriel))
                       .doesNotContainEntry(oneRing, aragorn); 
// and many more assertions : dates, file, numbers, exceptions ...
