[英]Junit test of a class requires objects of other classes
I have a class defined as such:我有一个 class 定义如下:
public class Monster {
public static final int ARENA_SIZE = 480;
public int health; //can be negative since it will then be removed
public int speed;
public int counter;
public int x; //current position
public int y; //current position
public mapObject next;
public void nextAlgorithm(mapObject[][] map) {
aNode[][] aNodeMap = newANodeMap(map); //1. create a new aNodeMap
PriorityQueue<aNode> pq = newPriorityMap(aNodeMap[this.x][this.y]); //2. create a new priority queue with starting point added
aNode current;
while (pq.isEmpty() == false) {
current = pq.poll();
if (endPointReached(current.x, current.y)) //3. Is the end point reached?
break;
aNode[] neighbours = findNeighbour(current.x, current.y, aNodeMap); //4. The end point isn't reached, find me the neigbours
for (aNode neighbour : neighbours) //5. process all my neighbours
processNeighbour(current, neighbour, pq);
}
next = updateNext(aNodeMap[ARENA_SIZE - 1][ARENA_SIZE - 1], this.x, this.y); //6. Update my next after all these work
}
Simply put, there is an algorithm that requires input from other class, the mapObject, which is also another self-written package by me.简单来说,有一个算法需要其他class输入,mapObject,也是我自己写的另一个package。
My question is, apart from我的问题是,除了
import MapObject.*;
in junit that allows me to initialize a fixture in在 junit 中,它允许我在
@Before
Are there any better ways?有没有更好的方法?
It's probably better to create the input object (ie the mapObject[][]
) in the test case itself, rather than in a @Before
method.在测试用例本身而不是在@Before
方法中创建输入 object (即mapObject[][]
)可能更好。 This allows you to create several test cases with different input objects.这允许您使用不同的输入对象创建多个测试用例。
Ie IE
@Test void testWithSpecificArrayConfiguration1() {
mapObject[][] objectConfig1 = createConfig1();
testMonster.nextAlgorith(objectConfig1);
// verification steps for config 1
}
@Test void testWithSpecificArrayConfiguration2() {
mapObject[][] objectConfig2 = createConfig2();
testMonster.nextAlgorith(objectConfig2);
// verification steps for config 2
}
As a note, it doesn't feel right that the input is a mapObject
, but the actual algorithm works on an aNode[][]
;请注意,输入是mapObject
感觉不对,但实际算法适用于aNode[][]
; but it's hard to tell without knowing the context of the code.但是如果不知道代码的上下文就很难说。
