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:
...assertDoesNotThrow()主要用来判定被测试方法是否抛出了异常,如果抛出异常则断言失败,无异常抛出则断言成功。...@Test void testtestAssertDoesSNotThrowHaveReturn(){ //这是带返回参数的assertDoesNotThrow方法,在没有异常抛出的情况下会返回一个值...} //如果捕获的异常和自定义的异常不同,通过自定义的打印...

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:...
