Thread: JUnit problems

Hi

This is my first time using JUnit and somehow this doesn't work. I have a class SoccerTeam and a
testclass SoccerTeamTest. I always get an initialization error so what do I have to change?

SoccerTeam:
package Soccer;

public class SoccerTeam {

String name;
int og, fg, matches;

public SoccerTeam(String name) {
this.name = name;
}

public void setName(String name) {
this.name = name;
}

public String getName() {
return name;
}

public void setMatches(int number) {
this.matches = number;
}

public int getMatches() {
return matches;
}

public int getOg() {
return og;
}

public void setOg(int og) {
this.og = og;
}

public int getFg() {
return fg;
}

public void setFg(int fg) {
this.fg = fg;
}

public void addMatchResult(int og, int fg) {
this.og += og;
this.fg += fg;
matches++;
}

@Override
public String toString() {
StringBuffer sb = new StringBuffer(256);
sb.append(name).append(" ").append(og).append(":").append(fg)
.append(" in ").append(matches).append(" matches.");
String a = sb.toString();
return a;
}
}

TestClass

package Tests;

import static org.junit.Assert.*;

import org.junit.Before;
import org.junit.Test;

import junit.framework.JUnit4TestAdapter;
import Soccer.SoccerTeam;


public class SoccerTeamTest {
public static SoccerTeam t = new SoccerTeam("Deutschland");

public static junit.framework.Test suite(){
return new JUnit4TestAdapter(SoccerTeam.class);
}

@Before
public void clear(){
t.setOg(0);
t.setFg(0);
t.setMatches(0);
}

@Test
public void oneGame(){
t.addMatchResult(4, 2);
assertEquals(t.getOg(), 4);
assertEquals(t.getFg(), 2);
assertEquals(t.getMatches(), 1);
}

@Test
public void threeGames(){
t.addMatchResult(0, 0);
t.addMatchResult(5, 1);
t.addMatchResult(2, 3);
assertEquals(t.getMatches(), 3);
assertEquals(t.getOg(), 7);
assertEquals(t.getFg(), 4);
}
}

I always get an initialization error

Without the text of the error messages, its hard to say what the problem is.
Can you compile the code with the javac command and post the full text of the error messages here?

Test class should have exactly one public zero-argument constructor

Do you understand what the error message is saying?
Does your code have more than one constructor?
Does your constructor have any arguments?

No that is my problem.
That is all of my code.
The constructor of SoccerTeam is:
public SoccerTeam(String name) {
this.name = name;
}
My testclass does not have one, do I need one?

I'm not familiar with JUnit.
The error message says there is a problem with your constructor.
Change the constructor to have zero-arguments, use the set method and see what happens.

Sorry, I don't know anything about how to use JUnit.

Shouldn't it be: t.setName("...");

Thanks for your help,
I found my mistake
It has to be: public static junit.framework.Test suite(){
return new JUnit4TestAdapter(SoccerTeamTest.class);
}
