我们接下来看一下 源码分析 首先，assertThrows有三个重载方法： public static T assertThrows(Class..., String message) { return AssertThrows.assertThrows(expectedType, executable, message);..., Supplier messageSupplier) { return AssertThrows.assertThrows(expectedType, executable..., messageSupplier); } 我们可以看到，其中都是调用了AssertThrows.assertThrows方法，这里的AssertThrows和Assertions的关系和我们在...接下来就看一下AssertThrows.assertThrows()到底是何许人也： private static T assertThrows(Class<
static org.junit.jupiter.api.Assertions.assertEquals; import static org.junit.jupiter.api.Assertions.assertThrows...DateUnit.HOUR)); assertEquals(1, ShiChen.toModernTime(time + "正").between(DateUnit.HOUR)); } assertThrows...(IllegalArgumentException.class, () -> ShiChen.toModernTime("无效时")); assertThrows(IllegalArgumentException.class..., () -> ShiChen.toModernTime("无效正")); assertThrows(IllegalArgumentException.class, () -> ShiChen.toModernTime...("")); assertThrows(IllegalArgumentException.class, () -> ShiChen.toModernTime(null)); } @Test

而JUnit5提供了一种新的断言方式Assertions.assertThrows() ,配合函数式编程就可以进行使用。...Test @DisplayName("异常测试") public void exceptionTest() { ArithmeticException exception = Assertions.assertThrows...} @DisplayName("异常断言") @Test void testException() { //断定业务逻辑一定出现异常 assertThrows...DisplayName("throws EmptyStackException when popped") void throwsExceptionWhenPopped() { assertThrows...DisplayName("throws EmptyStackException when peeked") void throwsExceptionWhenPeeked() { assertThrows
方法时是否抛出指定类型的异常； 如果execute方法执行时不抛出异常，或者抛出的异常与期望类型不一致，都会导致测试失败； 写段代码验证一下，如下，1除以0会抛出ArithmeticException异常，符合assertThrows...指定的异常类型，因此测试可以通过： @Test @DisplayName("判断抛出的异常是否是指定类型") void exceptionTesting() { // assertThrows...的第二个参数是Executable， // 其execute方法执行时，如果抛出了异常，并且异常的类型是assertThrows的第一个参数(这里是ArithmeticException.class...)， // 那么测试就通过了，返回值是异常的实例 Exception exception = assertThrows(ArithmeticException.class..., () -> Math.floorDiv(1,0)); log.info("assertThrows通过后，返回的异常实例：{}", exception.getMessage());

这两种方法都可以通过使用assertThrows（）方法来实现： Copy @Test void shouldThrowException() { Throwable exception = assertThrows...exception.getMessage(), "Not supported"); } @Test void assertThrowsException() { String str = null; assertThrows
