我想验证以下两个方法调用中的任何一个是否执行一次：

myLogger.logWarn("My 1st Warning Message"); // depending on some randomness in my program,
myLogger.logWarn("My 2nd Warning Message"); // one of these two get executed

我已尝试以下方法：

verify(myLogger).logWarn(or("My 1st Warning Message", "My 2nd Log Warning Message"));

但运行测试方法导致以下错误：

No matchers found for additional matcher Or(?)
-> at foobar.builder.StopBuilderTest.build(StopBuilderTest.java:141)

org.mockito.exceptions.misusing.InvalidUseOfMatchersException: 
No matchers found for additional matcher Or(?)
-> at foobar.builder.StopBuilderTest.build(StopBuilderTest.java:141)

当我只是测试单个方法调用时，如下所示..

verify(myLogger).logWarn("My 1st Warning Message");

..它运行得很好，当用参数"My 1st Warning Message"调用logWarn()时，我的测试总是成功的。
