创建动态测试的规则
- 不能是
privateor ,static。
- 返回类型必须为：
Stream、Collection、Iterable、或Iterator、DynamicNode。
返回类型
DynamicNode- Stream
- Collection
- Iterable
- Iterator
返回DynamicNode
- 返回DynamicTest
- 返回DynamicContainer

迭代器
-
Iterator
- 具有迭代状态的对象
- 有
hasNext()/next()
-
Iterable
- 是一系列可以迭代的元素 > Java中集合使用.iterator() 返回可迭代的对象
