junit.Framework.AssertionFailedError trying to Read From a File to a ArrayList

Question

I have to read from a file and then place the words that are found into a ArrayList.

public boolean load(String filename)
{

    try
    {
        BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("wordlist.txt")));
        String line = null;
        while ((line = br.readLine()) != null)
        {
            String[] values = line.split("\n");
            wordlist.add(new WordPair(answer, question));
        }
    } catch (IOException ioe)
    {
        Logger.getLogger(Controller.class.getName()).log(Level.SEVERE, null, ioe);
    }

    return false;
}

Below is the tester code I have used:

public void testLoad() {
    assertTrue(wordPairDemo.save(fileName));    
    wordPairDemo.clear();                       
    assertTrue(wordPairDemo.load(fileName));
    assertTrue(wordPairDemo.size() == 3);
    assertEquals(wordPairDemo.lookup("hest"),"horse");
    assertEquals(wordPairDemo.lookup("hus"), "house");
    assertEquals(wordPairDemo.lookup("båd"),"boat");
}

I get the junit.Framework.AssertionFailedError, and I am not sure what is causing it. I have tried several different types of ways of doing this, through scanners, etc. but I always get this error, and I am not sure what to do with it.

Any help appreciated! :)

As per your example in the comment below, the file contains pairs in single line: horse,hesthouse,husboat,båd

you should split according to the actual delimiter you're using - , . Eg:

public boolean load(String filename)
{
    try
    {
        BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("wordlist.txt")));
        String line = null;

        // I'm leaving this loop under the assumption that there may be multiple lines
        while ((line = br.readLine()) != null) 
        {
            String[] values = line.split(",");
            for (int i = 0; i < line.lenght() / 2; ++i) {
                wordlist.add(new WordPair(values[i], values[i + 1));
            }
        }
    } catch (IOException ioe)
    {
        Logger.getLogger(Controller.class.getName()).log(Level.SEVERE, null, ioe);
    }

    return false;
}
