Loop through array, each element a JUnit test
提问by Bart van Heukelom
I have a JUnit 4 test that loops through an array of test data:
我有一个循环测试数据数组的 JUnit 4 测试：
public @Test void testAll() {
final Object[][] sets = new Object[][] {
// SET TYPE VALUE
// --- valid sets
// groups
x(s(A,1, B,1, C,1), G),
x(s(A,4, B,4, D,4), G),
x(s(A,8, B,8, D,8, C,8), G),
x(s(J,J, B,4, D,4), G, 4*3),
x(s(A,9, J,J, D,9), G, 9*3),
x(s(A,2, B,2, C,2), G),
x(s(A,4, B,4, J,J), G, 4*3),
x(s(A,4, B,4, C,4, D,4), G),
// runs
x(s(A,1, A,2, A,3), R),
x(s(B,8, B,9, B,10), R),
x(s(J,J, C,2, C,3), R, 6),
x(s(D,8, D,9, J,J, D,11), R, 38),
x(s(D,8, D,9, J,J, J,J), R, 38),
// sames
x(s(A,1, A,1), S),
x(s(B,4, B,4, B,4), S),
x(s(C,8, C,8), S),
x(s(D,3, D,3), S),
// doubt-cases, assume group (TODO: verify this is correct)
x(s(J,J, J,J, D,4), G, 4*3),
x(s(A,7, J,J, J,J), G, 7*3),
x(s(J,J, D,9, J,J), G, 9*3),
x(s(J,J, J,J, J,J), G, 1),
// --- invalid sets
x(s(B,1, A,2, A,3), I), // not same colour
x(s(D,11, D,12, J,J, J,J), I), // last joker is 14
x(s(B,1, B,1, A,1), I), // duplicate B1
x(s(A,1, A,2, A,3, A,5), I), // gap A4
x(s(J,J, A,1, J,J, B,1, C,1), I), // one J replaces D1, then nothing left to replace
x(s(A,1, A,2), I), // short
x(s(B,1), I), // shorter
x(s(A,5, A,6), I), // short
};
for (Object[] o : sets) {
TileSet s = (TileSet) o[0];
Type t = (Type) o[1];
int v = (Integer) o[2];
System.out.println(s);
assertEquals(t, s.getType());
assertEquals(v, s.getValue());
// test isValid, though it's Too Simple To Break(R)
if (t == Type.INVALID) assertFalse(s.isValid());
else assertTrue(s.isValid());
}
}
Because it's all in one test method, the whole test stops as soon as one element in the array fails. Is there a way around that, without making a method for each test item? Maybe something with reflection?
因为它都在一个测试方法中，所以只要数组中的一个元素失败，整个测试就会停止。有没有办法解决这个问题，而不为每个测试项目制定一个方法？也许有反射的东西？

Use JUnit 4's parameterized tests. They are a perfect fit for this type of problem, although the documentation is quite lacking.
使用 JUnit 4 的参数化测试。它们非常适合此类问题，尽管文档相当缺乏。
Here are a few other samples on how to use them.:
以下是有关如何使用它们的其他一些示例。：

catch AssertionErrorand add the caught error to the errors list, at the end check the list to be empty raise a compound AssertionErrorif not.
捕获AssertionError并将捕获的错误添加到错误列表中，最后检查列表是否为空，AssertionError如果不是则提出复合。
