Please note that you need to use JUnit’s org.junit.Assert class in case of JUnit 4 or JUnit 3 to assert using assertNotNull method. Assertions.assertNotNull () checks if object is not null. In case, object is null, it will through AssertError. public static void assertNotNull (Object actual)

Here we will consider many ways to mock exceptions and assert exceptions with JUnit. Mocking Exceptions. With Mockito you can not only mock methods to return something but also you can mock them to throw exceptions using Mockito.when. First of all, most of the time, assert operations are simple comparisons that get enabled in development and disabled in production. Remember, they're internal checks to make sure a developer's assumptions are correct. They should not change the behavior of the application.

Assertions (by way of the assert keyword) were added in Java 1.4. They are used to verify the correctness of an invariant in the code. They should never be triggered in production code, and are indicative of a bug or misuse of a code path.

They should never be triggered in production code, and are indicative of a bug or misuse of a code path. assert is a debugging tool that will cause the program to throw an AssertionFailed exception if the condition is not true. In this case, the program will throw an exception if either of the two conditions following it evaluate to false. Generally speaking, assert should not be used in production code Generally, null variables, references, and collections are tricky to handle in Java code.Not only are they hard to identify, but they're also complex to deal with. As a matter of fact, any miss in dealing with null cannot be identified at compile time and results in a NullPointerException at runtime. It’s not appropriate to specify assert filespec != null; because the precondition mentioned in the constructor’s Javadoc would not (technically) be honored when assertions were disabled. (In fact, Assertions.assertNotNull () checks if object is not null.
