Use Java assertions to document program correctness and more quickly test and debug your programs
There are two ways in which an assert statement can be used. First Way − assert expression; Second Way − assert expression1 : expression2. By default, assertions are disabled in Java. In order to enable them we use the following command − However, JUnit Jupiter’s org.junit.jupiter.Assertions class does not provide an assertThat() method like the one found in JUnit 4’s org.junit.Assert class which accepts a Hamcrest Matcher. Instead, developers are encouraged to use the built-in support for matchers provided by third-party assertion libraries. Example for Hamcrest: 2020-09-10 · AssertJ is an opensource community-driven library used for writing fluent and rich assertions in Java tests.

2019-06-26 · Assertions in Java can be done with the help of the assert keyword. Suppose there is a condition that you, as a programmer or a developer, while testing your code, want to make sure exists, such as making sure that a particular method shall return only negative values; Java has a (relatively) new feature made available just for that.

public class Assert extends java.lang.Object. A set of assertion methods useful for writing tests. Only failed assertions are recorded. These methods can be used directly: Assert.assertEquals(), however, they read better if they are referenced through static import: import static org.junit.Assert.*; assertEquals(); See Also: AssertionError
In Java, the assert statement starts with the keyword ‘asset’ followed by a Boolean expression. Java assert keyword is used to create assertions in Java, which enables us to test the assumptions about our program.

This class of static methods provides basic assertion testing facilities.
While executing assertion, it is believed to be true. If it fails, JVM throws an error named AssertionError. History of Java Assert Java introduced the Java assert keyword in Java 1.4. However, this keyword remains a little-known keyword that can drastically reduce boilerplate and can provide more readability to our code. For example, we often need to verify certain conditions in our code that might prevent our application from working properly. An AssertionError is thrown if the condition evaluates to false. We have Joshua Bloch to thank for this language feature.
