莫基托与任何(类型)方法不匹配

Question

我测试了这段代码：

PublisherCallbackWithLog publisherCallback = new PublisherCallbackWithLog<String>();
for (SdkRequest.SdkRequest sdkRequest : SdkRequestsList.getRequestList()) {
final String s = TextFormat.printToUnicodeString(sdkRequest);
customPublisher.publish(s, publisherCallback);
}

在我的测试中，我有这一行：

verify(customPublisher, times(1)).publish(argThat(eqWithoutRequestId(sdkRequest)), any(PublisherCallbackWithLog.class));

但我得到一个错误，似乎是关于第二个参数。

Argument(s) are different! Wanted:
customPublisher.publish(
,
<any>
);

否则我应该如何验证呼叫？

调试时，它永远不会到达我的matchesSafely方法：

public class RequestMatcher extends TypeSafeMatcher<WazeSdkRequest.SdkRequest> {
private WazeSdkRequest.SdkRequest expectedRequest;
private RequestMatcher(final SdkRequest.SdkRequest request) {
this.expectedRequest = request;
}
@Override
protected boolean matchesSafely(final SdkRequest.SdkRequest sentRequest) {
boolean answer = SdkRequest.newBuilder(sentRequest).clearRequestId().build()
.equals(SdkRequest.newBuilder(expectedRequest).clearRequestId().build());
return answer;
}

public static RequestMatcher eqWithoutRequestId(final SdkRequest request) {
return new RequestMatcher(request);
}
@Override
public void describeTo(final Description description) {
}

Answer 1

我相信这是因为您在RequestMatcher上的泛型类型是WazeSdkRequest.SdkRequest，而您调用的方法(customPublisher.publish()(需要一个字符串。

如果你看一下TypeSafeMatcher.java中的代码，你可以看到它首先做了一个类型检查，看看它是否应该继续使用matchesSafely方法：

public final boolean matches(Object item) {
return item != null
&& expectedType.isInstance(item)
&& matchesSafely((T) item);
}

在这种情况下，我希望expectedType.isInstance(item)返回 false，这将导致您的测试失败。

此外，如果您实际实现describeTo并覆盖describerMismatchSafely，您可能已经能够更好地调试它。
