"No runnable Methods" exception

[Jaggywaggy]

I'm currently trying to build unit tests for on the method below:

public Card attackCard(Card attackingCard, Card targetCard) {
    mAttackingCardHit = attackingCard.getAttack();
    mTarget = targetCard.getHealth();
    mAttackingCardHealth = attackingCard.getHealth();
    mTargetCardAttack = targetCard.getAttack();

    targetCard.setHealth(mTarget - mAttackingCardHit);
    attackingCard.setHealth(mAttackingCardHealth - mTargetCardAttack);

    return targetCard;


}

I'm testing it using this method:

public void attackCardTestTargetCardHealthSuccessful() {
    CardInfo cardInfoAttackingCard = new CardInfo(2, 5);
    CardInfo cardInfoTargetCard = new CardInfo(2, 5);
    Card cardAttackingCard = new Card(cardInfoAttackingCard);
    Card cardTargetCard = new Card(cardInfoTargetCard);

    Attack attack = new Attack();

    attack.attackCard(cardAttackingCard, cardTargetCard);

    assertEquals(3, cardTargetCard.getHealth());



}

and the object being built are using the below constructors:

public CardInfo(int attack, int health){

    // Fill in member variables based on the arguments passed in
    mAttack = attack;
    mHealth = health;

}

public Card(CardInfo cardInfo) {

    mAttack = cardInfo.getAttack();
    mHealth = cardInfo.getHealth();
}

public Attack() {
}

But whenever the test is ran, it fails and gives this in my logcat:

Just from looking at the logcat I know I may have missed something and was hoping someone with a better pair of eyes might spot what I've done (or not done).

Thanks in advance.

You need to annotate one or more of your test class methods with @test. You're getting the error because JUnit can't find any such methods in your code.
