java IllegalArgumentException:预期块内的条件语句无效

Question

我在测试用例中编写的Expectations块有问题：

new Expectations() {
      {
        mFindHandlerMock.findAll((Model) any, (Set<Id>) any, false);
        if (!pWithRealData) {
          result = Collections.emptySet();
        } else {
          result = pAllData;
        }
        times = 1;

        Deencapsulation.invoke(mDb, "readSqlQuery", withAny(String.class));
        result = "select * from realdata";
        times = 1;
      }
    };

测试用例崩溃的原因是：

java.lang.IllegalArgumentException: Invalid conditional statement inside expectation block

就在这里：

if (!pWithRealData) {

这只是一个简单的boolean，在本例中是false

我完全不知道为什么会发生exception。 我已经用谷歌搜索过了，但没有找到任何有用的东西

你能帮我吗

从版本1.14的JMockit发行说明中：

Enhancement: Conditionals and loops will now trigger an exception when found inside an expectation recording block, to prevent API misuse and to encourage simpler tests. See issue #97.

与此相关的GitHub问题：

• https://github.com/jmockit/jmockit1/issues/123

在一期中，他们声明：

Yes, and this is as intended, to avoid tests getting too complicated when recording expectations. A full test was not shown, but it looks to me that recording the specific expectations directly would be better in this case.

在JMockitsource中，您可以看到哪些其他类型的条件和循环将引发该异常

简而言之，从JMockit 1.14开始，不允许在期望块中有条件语句（如if语句）和循环
