Language?

the entire pair [3, 7] appears earlier than [5, 5].

completed the initial tests but when I try to submit I fail for reasons of what seems to be an output of the deck size

The test cases people contributed for Haskell […] are a bit strange

The test cases in Haskell simply generate a list of random words.

I created simple test cases.

import org.junit.Assert;
import org.junit.Test;

public class TestCaffeineBuzz {
@Test
public void testOutputJava() {
Assert.assertEquals("Java", CaffeineBuzz.caffeineBuzz(3));
}

@Test
public void testOutputJavaScript() {
	Assert.assertEquals("JavaScript", CaffeineBuzz.caffeineBuzz(6));
}

@Test
public void testOutputCoffeeScript() {
	Assert.assertEquals("CoffeeScript", CaffeineBuzz.caffeineBuzz(12));
}

@Test
public void testOutputMochaMissing() {
	Assert.assertEquals("mocha_missing!", CaffeineBuzz.caffeineBuzz(1));
}

}

The test cases people contributed for Haskell, and particularly Java are a bit strange. The original kata is string in, string out. I think following that model might help you with the Java test cases.

Confused about the "testEmptyArg" part of the tester. It seems to ignore the null I have my code return of the string is empty.

The test class area is empty and i'm not sure how to write the test class like the other katas. Any help?
