我有一个最后的课,类似这样:

public final class RainOnTrees{

   public void startRain(){

        // some code here
   }
}

我在其他类中使用此类,如下所示:

public class Seasons{

   RainOnTrees rain = new RainOnTrees();

   public void findSeasonAndRain(){

        rain.startRain();

    }
}

在我的JUnit测试类中,Seasons.java我想模拟这个RainOnTrees类.我怎么能和Mockito一起做这件事？

我写了以下内容JsonSerializer让Jackson将一个整数数组序列化为JSON:

import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.SerializerProvider;
import java.io.IOException;

public class TalkIdsSerializer extends JsonSerializer<TalkIds> {

    /**
     * Serializes a TalkIds object into the following JSON string:
     * Example: { "talk_ids" : [ 5931, 5930 ] }
     */
    @Override
    public void serialize(TalkIds talkIds, JsonGenerator jsonGenerator, 
        SerializerProvider provider)
            throws IOException {
        jsonGenerator.writeStartObject();
        jsonGenerator.writeArrayFieldStart(TalkIds.API_DICTIONARY_KEY);
        for (Integer talkId : talkIds.getTalkIds()) {
            jsonGenerator.writeNumber(talkId);
        }
        jsonGenerator.writeEndArray();
        jsonGenerator.writeEndObject();
    }

}

该类在这里使用:

@JsonSerialize(using = TalkIdsSerializer.class)
public class TalkIds { /* ...  */ }

我想测试序列化器的行为,并提出以下内容: …
