一.外部测试用例创建new对象时，构造函数里因执行super(context)；会报错，寻找解决方法
oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMyNjc1MjY3,size_16,color_FFFFFF,t_70#pic_center)
```java
// super调用到这里
public AbsAction(Context var1) {
boolean var10000 = true;
JniLib1606719255.cV(new Object[]{this, var1, 4});
}
```
1.使用powermock.spy(new ActionExecuter(context));因还是会调用构造函数，*Failed*
2.不能使用打桩@Mock，因为需要测试该类中的其它方法（此为目的） *Failed*
3.反射：“获取类中的有残构造方法就可以通过反射**执行这个有参构造方法**就可以构建对象” ，*Failed*
4.不创建对象，直接调用方法，根本原理上就无法实现 *Failed*
5.`PowerMockito.mockStatic(JniLib1606719255.class);`也不行，会报错（安卓原生问题）：*Failed*
```java
java.lang.UnsatisfiedLinkError: android.util.Log.println_native(IILjava/lang/String;Ljava/lang/String;)I
at android.util.Log.println_native(Native Method)
at android.util.Log.e(Log.java:240)
```
6.外部新建类继承该源码类：因该类只有有参构造函数，继承出来的类中的构造函数还是要执行super才行，否则报错：`There is no default constructor available in 'com.desaysv.adapter.sceneengine.ActionExecuter'` *Failed*
7.在第6方法上，继承后，写一个有参构造函数，再写一个无参构造函数，也不行。和6同理 *Failed*
8.放弃，改源码，加个无参构造函数，也不行，和6、7同样情况 *Failed*
9.没法搞，该类暂无法单元测试，使用实机的灰盒继承测试
二、Powermockito.doNothing提示错误：
```cpp
Cannot access org.mockito.stubbing.BaseStubber
```
1.添加mockito-all依赖，不行： `testImplementation group: 'org.mockito', name: 'mockito-all', version: '1.10.19'` *Failed*
2.Mockito-core 3.8+因将DoesNothing()改为了私有，无视即可，直接运行：
```cpp
public static PowerMockitoStubber doNothing() {
return POWERMOCKITO_CORE.doAnswer(new DoesNothing());
}
``
```cpp
//.Mockito-core 3.8
private DoesNothing() {}
```
三、mock对象空指针问题，（记录）
```cpp
//测试代码
repositoryProxy = PowerMockito.mock(RepositoryProxy.class);
repositoryProxy.bind(Mockito.any(),Mockito.any(),Mockito.any());
```
会报错：
```cpp
java.lang.NullPointerException
at com.desaysv.adapter.sceneengine.manager.MediaManagerTest.init(MediaManagerTest.java:57)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)

at org.powermock.modules.junit4.internal.impl.PowerMockJUnit44RunnerDelegateImpl$PowerMockJUnit44MethodRunner.executeTest(PowerMockJUnit44RunnerDelegateImpl.java:300)
```
四、Mockito.verify()参数报错问题
```objectivec
//源码
Mockito.verify(repositoryProxy).bind(context,Target.RADIO,Mockito.any());
```
```
org.mockito.exceptions.misusing.InvalidUseOfMatchersException:
Invalid use of argument matchers!
3 matchers expected, 1 recorded:
-> at com.desaysv.adapter.sceneengine.manager.MediaManagerTest.init(MediaManagerTest.java:59)
This exception may occur if matchers are combined with raw values:
//incorrect:
someMethod(anyObject(), "raw String");
When using matchers, all arguments have to be provided by matchers.
For example:
//correct:
someMethod(anyObject(), eq("String by matcher"));
```
方法：按照要求修改参数，如Matchers.eq(Target.RADIO)，改为：
```objectivec
Mockito.verify(repositoryProxy).bind(Matchers.eq(context),Matchers.eq(Target.RADIO),Mockito.any());
```

五、MeadiPlayer等安卓原生类无法被mock
六、今天ROBO配置与测试卡在如下报错：2021-04-01
```objectivec
WARNING: No manifest file found at .\AndroidManifest.xml.
No such manifest file: .\AndroidManifest.xml
Falling back to the Android OS resources only.
To remove this warning, annotate your test class with @Config(manifest=Config.NONE).
[Robolectric] com.desaysv.adapter.sceneengine.manager.RoboTest.myTest: sdk=27; resources=legacy
[Robolectric] NOTICE: legacy resources mode is deprecated; see robolectric点org/migrating/#migrating-to-40
```
问题点可能出现在@config（）中无法配置如下内容导致，仍待研究。。。
```objectivec
constants = BuildConfig.class
```
七、模拟测试回调函数时，用powermock或者Mockito.doAnswer()都可以，因此可以运用在安卓实机测试上，如：
```objectivec
//onPreparedListener = (MediaPlayer.OnPreparedListener)ol;获取到要测试的回调函数
doAnswer(new Answer<Object>() {
public Object answer(InvocationOnMock invocation) throws IOException {
Object[] args = invocation.getArguments();
Object ol = args[0];
if(ol instanceof MediaPlayer.OnPreparedListener){
onPreparedListener = (MediaPlayer.OnPreparedListener)ol;
}
return null;
}
}).when(mediaPlayer).setOnPreparedListener(Mockito.any(MediaPlayer.OnPreparedListener.class));
```
