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 tearDown

Each 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);

}

}
