Gain insights into configuring and utilizing JUnit 5 for Java unit testing. Learn about writing effective unit tests, integrating assertions, assumptions, parameterized tests, and their significance.

Junit 5 is the most popular and widely used Java unit testing framework. In this course, you will learn step by step, how to configure and use JUnit 5 testing framework. This course will teach you how to write unit tests with JUnit 5, covering topics like why unit tests are important, the structure of good unit tests, assertions, assumptions and parameterized tests and more.

Java Unit Testing with JUnit 5

# assertSame() method ###

Assertions API provide static `assertSame()` method. This method helps us in validating that `expected` and `actual`refer to the exact same object. JUnit uses `==` operator to perform this assert.

- If the actual and expected value refers to the same object then the test case will pass.
- If the actual and expected value does not refer to the same object then the test case will fail.


There are basically three useful overloaded methods for assertSame:-

public static void assertSame(Object expected, Object actual)
  
public static void assertSame(Object expected, Object actual, String message)
  
public static void assertSame(Object expected, Object actual, Supplier<String> messageSupplier)

# Demo ###

Let's look into the usage of the above methods:- 

This lesson demonstrates how to use assertSame method in JUnit 5 to assert test conditions.
