英文:
Ignoring only embedded member in AssertJ
问题
我有两个类需要用`JUnit`/`Mockito`进行测试：
public class ClassA {
private int sk;
// getters and setters
}
public class ClassB {
private int sk;
private List<ClassA> lista;
// getters and setters
}
然后在我的测试类中，使用`AssertJ`：
List<ClassA> lista = //... 用ClassA对象的列表填充
ClassB expected = new ClassB();
expected.setSk(5);
expected.setLista(lista);
ClassB actual = getItFromTheClassToTest();
assertThat(actual).usingRecursiveComparison()
.ignoringFields("sk") // 需要仅在ClassA中忽略sk字段
.isEqualTo(expected);
问题是`sk`字段在两个类中都存在，我需要仅在`ClassA`中忽略它，而不是在`ClassB`中忽略。这在`AssertJ`中是否可行？
英文:
I have two classes to test with JUnit/Mockito:
public class ClassA {
private int sk;
// getters and setters
}
public class ClassB {
private int sk;
private List<ClassA> lista;
// getters and setters
}
Then in my test class, using AssertJ:
List<ClassA> lista = //... populated with list of objects of ClassA
ClassB expected = new ClassB();
expected.setSk(5);
expected.setLista(lista);
ClassB actual = getItFromTheClassToTest();
assertThat(actual).usingRecursiveComparison()
.ignoringFields("sk") // need to ignore only classA.sk
.isEqualTo(expected);
The problem is that the name sk is in both classes, and I need to ignore it only in ClassA, not in ClassB. Is this possible in AssertJ?

根据ignoringFields的Javadoc：
> 嵌套字段可以像这样指定：home.address.street。
...所以使用您的类：
ClassB b = new ClassB(1, Arrays.asList(new ClassA(1)));
ClassB bIsEqualsExceptForNestedField = new ClassB(1, Arrays.asList(new ClassA(2)));
ClassB bIsNotEquals = new ClassB(2, Arrays.asList(new ClassA(3)));
// 应该成功
assertThat(b)
.usingRecursiveComparison()
.ignoringFields("lista.sk")
.isEqualTo(bIsEqualsExceptForNestedField);
// 应该失败
assertThat(b)
.usingRecursiveComparison()
.ignoringFields("lista.sk")
.isEqualTo(bIsNotEquals);
英文:
According to the ignoringFields javadoc:
> Nested fields can be specified like this: home.address.street.
...so with your classes:
ClassB b = new ClassB(1, Arrays.asList(new ClassA(1)));
ClassB bIsEqualsExceptForNestedField = new ClassB(1, Arrays.asList(new ClassA(2)));
ClassB bIsNotEquals = new ClassB(2, Arrays.asList(new ClassA(3)));
// should succeed
assertThat(b)
.usingRecursiveComparison()
.ignoringFields("lista.sk")
.isEqualTo(bIsEqualsExceptForNestedField);
// should fail
assertThat(b)
.usingRecursiveComparison()
.ignoringFields("lista.sk")
.isEqualTo(bIsNotEquals);
