Jmockit：无法将 returns() 用于集合和多次调用？

Question

我要模拟的函数：

class Bar {
  public Set<Foo> getFoos();
}

被测代码：

for (int i = 0; i < n; ++i) {
  Bar bar = computeBar();
  for (Foo f : bar.getFoos()) {
    // code
  }
}

期望块：

new Expectations() {{
  bar.getFoos();
  returns(/* what should I put here?? */);
}};

Answer 1

要么写

new Expectations() {{ bar.getFoos(); returns(foo1, foo2, foo3); }};

到return一组，或

final Set<Foo> foos1 = new HashSet<Foo>(asList(foo1, foo2));
final Set<Foo> foos2 = new HashSet<Foo>(asList(foo3, foo4, foo5));
new Expectations() {{ bar.getFoos(); returns(foos1, foos2); }};

到return一组序列。
