What Is JUnit TestCase

  • 20 Jan, 2012

    JUnit TestCase is the base class, junit.framework.TestCase, used in JUnit 3.8 that allows you to create a test case. TestCase class is no longer supported in JUnit 4.4.A test case defines the fixture to run multiple tests. To define a test case * Implement a subclass of TestCase * Define instance variables that store the state of the fixture * Initialize the fixture state by overriding setUp * Clean-up after a test by overriding tearDownEach test runs in its own fixture so there can be no side effects among test runs. Here is an example:import junit.framework.*;public class MathTest extends TestCase { protected double fValue1; protected double fValue2; protected void setUp() { fValue1= 2.0; fValue2= 3.0; } public void testAdd() { double result= fValue1 + fValue2; assertTrue(result == 5.0); }}
