JUnit 4 was released Feb 16, 2006. With its release came annotations and the ability to write JUnit tests in a more flexible fashion than the setUp, test, and tearDown of 3.8. JUnit 4 took three and a half years to show up after the 3.8.1 release but since then there have been ten more releases -- 4.11 came out in December, 2012 and 4.12 is in the works. So here we are ten releases and eight
I agree totally with the OP point of view. Assert.assertFalse(expected.equals(actual)) is not a natural way to express an inequality. But I would argue that further than Assert.assertEquals(), Assert.assertNotEquals() works but is not user friendly to document what the test actually asserts and to understand/debug as the assertion fails. So yes JUnit 4.11 and JUnit 5 provides Assert 2018-04-08 Note: This course is still in progress.

I’ve found it very useful in my coding experiences but it seems very few developers know about it. I hope this post helps enlighten you to what you can do with this new way of writing assertions. But I would argue that further than Assert.assertEquals(), Assert.assertNotEquals() works but is not user friendly to document what the test actually asserts and to understand/debug as the assertion fails. So yes JUnit 4.11 and JUnit 5 provides Assert.assertNotEquals() (Assertions.assertNotEquals() in JUnit 5) but I really avoid using them.

A good assert message (which shows up if the test fails) is jey to understanding what went wrong. Assuming writing good assert messages is one of the key places where most unit test developers fall short, the only thing left to save us then is the name of the test.
How to assert greater than using JUnit Assert? · Just how you've done it. · When using JUnit asserts, I always make the message nice and clear. · you can also try

org.junit Class Assert java.lang.Object org.junit.Assert. public class Assert extends java.lang.Object. A set of assertion methods useful for writing tests.
In order to increase the readability of the test and of the assertions itself, it's always recommended to import statically the respective class. Implementation Of JUnit Assertions. Deep diving into the actual implementation of Assertions, both JUnit 4 and JUnit 5 have different classes that contemplate various assert methods each serving its own unique purpose. JUnit 4 has all the assert methods under the Assert class while JUnit 5 has all the assert methods under the Assertions class.
It is generally good practice to have a JUnit test case for every Java class. Within that JUnit test case, one or more JUnit unit tests should be written for every source-code method. 2.1. Imports In JUnit 4.4, three packages should be imported: import static org.junit.Assert.*;
In Junit 4.x, all the testing methods are identified with @Test annotation.so, the method testCalculate will be identified as test method and will be run by the Junit runner.; If you are using an IDE such as Eclipse, the PayrollTestCase class can be executed by right clicking on the test class and selecting Run as JUnit test case. This will invoke the test environment methods, if any
Pact consumer. Pact Consumer is used by projects that are consumers of an API. Most projects will want to use pact-consumer via one of the test framework specific projects. If your favourite framework is not implemented, this module should give you all the hooks you need.

assertEquals () calls equals () on your objects, and there is no way around that. What you can do is to implement something like public boolean like (MyClass b) in your class, in which you would compare whatever you want. Then, you could check the result using assertTrue (a.like (b)).
I can see that we have innovative requirements but IMHO these …
