To keep things simple, all JUnit Jupiter assertions are static methods in the org.junit.jupiter.Assertions class. junit中的assert方法全部放在Assert类中，总结一下junit类中assert方法的分类。 1. assert True/False([String message,]boolean condition); 用来查看变量是是否为false或true，如果 assert False()查看的变量的值是false则测试成功，如果是true则失败， assert True()与之相反； Junit4 Assert assertTrue()方法.

public class Assert extends junit.framework.Assert. A set of assert methods (primarly testing the negative assertion of the correspondent methods found in the junit.framework.Assert class). Usage Junit 5’s org.junit.jupiter.Assertions class provides different static assertions method to write test cases. Please note that you need to use JUnit’s org.junit.Assert class in case of JUnit 4 or JUnit 3 to assert using assertNull method. Assertions.assertNotSame() checks whether expected and actual object refer to different objects. 2019-04-19 Using the AggregatedAsserts class is intentionally similar to using the Junit Assert library.

Object class. There are various types of assertions like Boolean, Null, Identical et public static void assertArrayEquals (boolean[] expected, boolean[] actual, Supplier messageSupplier) Asserts that expected and actual boolean arrays are equal. If both are null , they are considered equal. Asserting Boolean Values If we want to verify that a boolean value is true, we have to write our assertion by invoking the isTrue () method of the AbstractBooleanAssert class. In other words, we have to use an assertion that looks as follows: 1 Many automated testers use the JUnit Assert library to perform test validations. When JUnit Assertion errors (test failures) occur, your test will stop executing and will not perform any remaining Assertions. For tests containing only a single Assertion, При написании тестов мы практически всегда используем утверждения, большинство из которых находятся в классе Assert.
