如何在Junit5中测试方法

标签： java junit5

我必须在一个类中使一个junit测试成为一种方法，但是我从来没有做过这样的事情，并且Internet上的所有信息都用于简单的计算测试。老实说，我不知道如何为我的方法实现测试，但是我尝试了一次布尔检查，但它并没有真正帮助我，也许有人可以给我一个指针。

我看了一些有关Junit的教程，但没有帮助我，因为它们是简单的方法。我尝试了一次布尔检查，但无法正常工作

public void takeDamage(int damage) {

    if (!todelete) {
        damage = damage / damagereduction;
        currentLife -= damage;
    }
    if (currentLife <= 0) {
        todelete = true;
        return;
    }
    if (currentLife >= 100) {
        sprite.setTexture(skins[0]);
        currentLife = 100;
        return;
    }
    int life = currentLife / 20;
    sprite.setTexture(skins[life]);
}

因此，此方法根据我的角色的健康状况将其角色图像更改为固定图像。我不知道如何测试这种方法。也许有人可以给我指点。

使用您提供给我们的信息进行的简单测试看起来像这样。

您需要调整所需的方法，类名和实际值。

broker.xml

如果纹理存储在其他位置，则还需要获取保持对象以验证纹理。

这是我遇到的错误，我认为它与方法本身无关，而更像是导入错误。
