+## Mock simulation return data
+
+Sometimes we just test some apis or service modules, where the service or dao returns null values for some methods by default, but if the logic includes the judgment or secondary value of the returned null object, it is to throw some exceptions
+
+Example:  
+
+```java
+    PageInfo<UDFAddVo> pageInfo =
+        udfService.getManagerPages(udfName, udfTypes, userName, curPage, pageSize);
+    message = Message.ok();
+    // The pageInfo here is null, and subsequent get methods will have exceptions
+    message.data("infoList", pageInfo.getList());
+    message.data("totalPage", pageInfo.getPages());
+    message.data("total", pageInfo.getTotal());
+```
+
+Example of mock simulation data:
+
+```java
+    PageInfo<UDFAddVo> pageInfo = new PageInfo<>();
+    pageInfo.setList(new ArrayList<>());
+    pageInfo.setPages(10);
+    pageInfo.setTotal(100);
+    // For udfService.getManagerPages method passes parameters arbitrarily, and the simulation returns the pageInfo object
+    // With this simulation data, the above example will not have exceptions when executing the get method
+    Mockito.when(
+            udfService.getManagerPages(
+                Mockito.anyString(),
+                Mockito.anyCollection(),
+                Mockito.anyString(),
+                Mockito.anyInt(),
+                Mockito.anyInt()))
+        .thenReturn(pageInfo);
+```

+## Mock模拟返回数据
+
+有时我们单测一些api或者service模块,其中的service或者dao对于一些方法的返回值默认是null,但是逻辑里面有对这个返回null的对象进行判断或者二次取值的话,就是引发一些异常
+
+示例:
+
+```java
+    PageInfo<UDFAddVo> pageInfo =
+        udfService.getManagerPages(udfName, udfTypes, userName, curPage, pageSize);
+    message = Message.ok();
+    // 这里的pageInfo是null,后续的get方法就会出现异常
+    message.data("infoList", pageInfo.getList());
+    message.data("totalPage", pageInfo.getPages());
+    message.data("total", pageInfo.getTotal());
+```
+
+mock模拟数据示例:
+
+```java
+    PageInfo<UDFAddVo> pageInfo = new PageInfo<>();
+    pageInfo.setList(new ArrayList<>());
+    pageInfo.setPages(10);
+    pageInfo.setTotal(100);
+    // 对 udfService.getManagerPages 方法进行任意传递参数,模拟返回pageInfo对象
+    // 有了这个模拟数据,上面示例在执行get方法的时候,就不会有异常
+    Mockito.when(
+            udfService.getManagerPages(
+                Mockito.anyString(),
+                Mockito.anyCollection(),
+                Mockito.anyString(),
+                Mockito.anyInt(),
+                Mockito.anyInt()))
+        .thenReturn(pageInfo);
+```
 
 ## 单元测试的编写
+
 ### 类的划分
+
 按类的大功能可以大体分类
 - Controller  提供http服务的controller 配合mockmvc做单元测试 
 - Service   业务逻辑代码的service层
