如何验证具有不同参数的多个方法调用

2022-01-14 00:00:00 mockito java

我有以下方法希望验证其行为.

I have the following method that I wish to verify behaviour on.

public void methodToTest(Exception e, ActionErrors errors) {
    ...

    errors.add("exception.message", 
            ActionMessageFactory.createErrorMessage(e.toString()));

    errors.add("exception.detail",
            ActionMessageFactory.createErrorMessage(e.getStackTrace()[0].toString()));

    ...
}

在我的@Test 类中，我希望做这样的事情来验证 errors.add() 是用exception.message"调用的.再次使用exception.detail"

In my @Test class I was hoping to do something like this to verify that errors.add() is called with "exception.message" and again with "exception.detail"

verify(errors).add(eq("exception.message"), any(ActionError.class));
verify(errors).add(eq("exception.detail"), any(ActionError.class));

然而 Mockito 抱怨如下

however Mockito complains as follows

Argument(s) are different! Wanted:
actionErrors.add(
    "exception.message",
    <any>
);

Actual invocation has different arguments:
actionErrors.add(
    "exception.detail",
    org.apache.struts.action.ActionError@38063806
);

如何让 Mockito 检查这两个值?

How can I tell Mockito to check for both values?

推荐答案

进一步阅读使我尝试使用 ArgumentCaptors 和以下作品，尽管比我想要的要冗长得多.

Further reading has led me to try using ArgumentCaptors and the following works, although much more verbose than I would like.

ArgumentCaptor<String> argument = ArgumentCaptor.forClass(String.class);

verify(errors, atLeastOnce()).add(argument.capture(), any(ActionMessage.class));

List<String> values = argument.getAllValues();

assertTrue(values.contains("exception.message"));
assertTrue(values.contains("exception.detail"));
