Junit query

[steve low]

Hi guys im doing Junit testing and im having a problem. Im using Eclipse which can also allow the Junit to copy the testing in a text doc. but the problem is ive been using if's which is a probelm because to save the Junit test in text document I have to use assertEquals instead of if. but im not sure how i would use it. Can sumone show me an example of how i would use the assertEquals in my current statement below. Thanks aot.

Thanks alot

public void testPlayerselecta() {
 
game.numberofplayers = 2;

 //assertEquals();
 
 if ((game.numberofplayers !=2) && (game.numberofplayers !=3) && (game.numberofplayers !=4) && (game.numberofplayers != 5));
System.out.println("Bad number of players");

assert (game.numberOfPlayers >= 2 && game.numberOfPlayers <= 5);

For JUnit, you'd want to say assertTrue() rather than assert. Otherwise I agree with Mark. There's really no way to do this with assertEquals(). If you do this sort of thing more than once or maybe twice, I'd create a custom assert statement (or two) that can be reused in other tests:

public static void assertInRange(String msg, int min, int max, int actual) {
    if (actual < min || actual > max) 
        fail((msg == null ? "" : msg + " - ") + "value " + actual + " outside expected range [" + min + ", " + max + "]");
}
 
public static void assertInRange(int min, int max, int actual) {
    assertInRange(null, min, max, actual);
}

It's a bit more work to put diagnostic info into the error messages, but it's often worth it, in my opinion.
