assert Keyword in Java The assert keyword in Java is used for debugging purposes. It allows developers to test assumptions about their code. Assertions can be enabled or disabled when the program is run, making them a flexible tool for catching and diagnosing errors during development.Usage...
However, assertions should not be taken as a replacement for error messages. Neither the assertions should be used in public methods,for example,to check arguments. Most importantly we should not use assertions on command-line arguments in Java. In Java, assertions are disabled by default. So f...
In this article, we will learn how to assert thrown exceptions in Java using JUnit 5 and AssertJ assertion libraries. Overview We usually write a unit test to verify the expected output from a piece of code. We also expect that this piece of code can throw an exception in some situations ...
