Unit testing definition. Unit testing is a method of testing individual units of source code to determine if they are fit for use. Unit tests are the smallest testable parts of an application. Is performed at the development phase of a software’s life cycle. Detects problems early in the development process.

Assert is a method useful in determining Pass or Fail status of a test case, The assert methods are provided by the class org.junit.Assert which extends java.lang.Object class. There are various types of assertions like Boolean, Null, Identical etc. Junit provides a class named Assert, which provides a bunch of assertion methods useful in writing

They fall under some fairly expected names. assertEquals – makes sure the two things compared are “equal” assertFalse – makes sure the thing has a value of “false” As can be seen JUnit’s new assertThat method has much better functionality than the old assert methods. 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. 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.

import org.junit.Test; import static org.junit.Assert.*; public class TestAssertions { @Test public void testAssertions() { //test data String str1 = new String ("abc"); String str2 = new String ("abc"); String str3 = null; String str4 = "abc"; String str5 But it's best to put a message so that you know why the test failed: Assert.IsTrue(actualCount > 5, "The actualCount was not greater than five"); – McKay Nov 9 '10 at 20:20 4 @McKay: I personally find that a wasted effort. @Test public void testName() { int i = 5; junit.framework.Assert.assertTrue(i == 3 || i == 5); } its passing always so i guess there is some inbetween code when your value is changed.

Assertions are the statements that are used to assert conditions in tests. In this article, we will go through different methods that are present in the Assertions( in JUnit5) class. All the methods in Assertions class are static and for the readability purpose it is recommended to static import all methods of Assertions.class 1.

A JUnit test case is usually associated with a single Java 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.*;
