Unit testing with inject annotation

以下是翻译好的内容:

如何对使用 @inject 注解的类进行单元测试:类 A{

@inject
private B b;

void foo(){
    b.funcInClassB();
}

我对单元测试还不太熟悉,因为在调用 b.funcInClassB() 时会抛出空指针异常,因为 b 为空。我编写了以下测试:

class Atest{
   @MockBean
   private B b;
   @Test
   void foo(){
     when(b.funcInClassB()).willReturn("something");
      A a = new A();
      a.foo();
   }
}
英文:

How do I unit test a class that uses @inject annotation:class A{

@inject
private B b;

void foo(){
    b.funcInClassB();
}

I am new to unit testing and having troubles testing this function because when calling b.funcInClassB() it throws NullPointerException because b is null.
I wrote the following test:

class Atest{
   @MockBean
   private B b;
   @Test
   void foo(){
     when(b.funcInClassB()).willReturn("something");
      A a = new A();
      a.foo();
   }
}

我找到解决方法:

class Atest{
   @MockBean
   private B b;
   
   @Autowired
   A a;   

   @Test
   void foo(){
     when(b.funcInClassB()).willReturn("something");
      // A a = new A();
      a.foo();
   }
}
英文:

I figured it out:

class Atest{
   @MockBean
   private B b;
   
   @Autowired
   A a;   

   @Test
   void foo(){
     when(b.funcInClassB()).willReturn("something");
      // A a = new A();
      a.foo();
   }
}
