第一步:导入assertDoesNotThrow方法所在的类 在开始之前,我们首先需要导入org.junit.jupiter.api.Assertions类,这个类中包含了assertDoesNotThrow方法。可以通过以下代码来实现: importstaticorg.junit.jupiter.api.Assertions.assertDoesNotThrow; 1. 第二步:编写测试用例和测试代码 在使用assertDoesNotThrow方法之前,我们需要...

Q #1) Does assert throw an exception Java? Answer:Assert usually throws “AssertionError” when the assumption made is wrong. AssertionError extends from Error class (that ultimately extends from Throwable). Q #2) What happens when an assert fails in Java?
Normal mode is typically the mode that you use during development, while optimized mode is what you should use in production. Now, what does __debug__ have to do with assertions? In Python, the assert statement is equivalent to the following conditional:...
funthisFunctionDoesNothing() {println("i did nothing") } @Testfun`this test should not fail, unfortunately it does`() { assertThatThrownBy { thisFunctionDoesNothing() }.doesNotThrowAnyException() } And i get the exception: Expecting code to raise a throwable. java.lang.AssertionError: Expe...
