AssertJ Core
AssertJ is a Java library that enables developers to create concise and readable test code. The power of AssertJ is shown by one of their nice examples on the docs page:
assertThat(fellowshipOfTheRing).hasSize(9)
.contains(frodo, sam)
.doesNotContain(sauron);
AssertJ has an extensive collection of assertions, making the possibilities almost endless. It is an alternative to JUnit’s own assertion module, offering clearer and more specific options. A nice example comes from the assertEquals, where AssertJ clarifies the positions of the expected / actual values:
// JUnit
assertEquals(42, 40 + 2);
// AssertJ
assertThat(40 + 2).isEqualTo(42);
In our project, we focus on the core module containing the assertions for standard JDK types.
