Assertions in JUnit 5
JUnit 5 assertions help us in validating the expected output with the actual output of a test case. In short, assertions are nothing but static methods that we call in our tests to verify expected behavior. All JUnit Jupiter assertions are present in the org.junit.jupiter.Assertions class.
These methods support Java 8 lambda expressions and are extensively overloaded to support different types such as primitives, objects, streams, arrays etc.
