Junit fail assertion method fails the test by throwing an assertion error, the fail method is used in junit version 4 and it will use the org.junit.Assert class. The junit fail method is used to verify that the actual exception will throw an error or the test is failing at the time of...

JUnit 5 builds on this foundation with new annotations like @BeforeEach and @AfterEach and improved features like more flexible test lifecycle managemen...
Below are the helper classes to provide constraints to the assert method. Is Has Throws Contains Does Assert.That( myString, Is.EqualTo("LambdaTest") ); 1 Assert.That( myString, Is.EqualTo("LambdaTest") ); In the example that was shown above, Is is the helper class, and EqualTo ...
In this section, we will use JUnit annotations to write test cases. Now, let’s add methods to demonstrate the usage of @BeforeAll, @BeforeEach, @AfterAll, @AfterEach, @Test, @DisplayName and @Disabled annotations. @DisplayName("Demo Test class") public class BasicTest { @BeforeAll publi...
