How To Write a Single Class to Define Multiple Tests and Run Them?
Here is the answer for JUnit 3.8:
1. Define a subclass of junit.framework.TestCase.
2. Override the setUp() and tearDown() methods.
3. Define multiple "public void testXXX()" methods.
One for each test.
A test method name must be started with "test".
Call the methods of tested object.
Check the expected results with an assertXXX() method.
4. Define a "public static void main()" method to run tests.
Call "junit.textui.TestRunner.run()" to run all tests.
Here is a nice example:
import junit.framework.*;
import junit.textui.*;
// by FYICenter.com
public class MathTestAndRun extends TestCase {
protected double fValue1;
protected double fValue2;
public static void main(String[] a){
junit.textui.TestRunner.run(MathTestAndRun.class);
}
protected void setUp() {
fValue1= 2.0;
fValue2= 3.0;
}
public void testAdd() {
double result= fValue1 + fValue2;
assertTrue(result == 5.0);
}
public void testMultiply() {
double result= fValue1 * fValue2;
assertTrue(result == 6.0);
}
}
