问题

我正在尝试创建一个非常简单的测试用例，以测试Hibernate Bean Validation中的自定义验证器。这个自定义验证器有一个注入点。

Junit4，BeanValidation 6.1.5.Final，WeldUnit 2.0.0.Final

```java
public class AssertCrsForOffshoreTest extends TestBase {

    //CHECKSTYLE:OFF
    @Rule
//    public WeldInitiator weld = WeldInitiator.from( ValidatorFactory.class ).inject( this ).build();
    public WeldInitiator weld = WeldInitiator.from( ValidatorFactory.class ).build();
    //CHECKSTYLE:ON
    
    @Test
    public void testValidCrs() {

        // prepare test
        BroLocation location = createLocation();
        location.setCrs( BroConstants.CRS_WGS84 );
        BeanWithLocation bean = new BeanWithLocation(  location );

        // action
        Set<ConstraintViolation<BeanWithLocation>> violations = weld.select( ValidatorFactory.class ).get().getValidator().validate( bean );

        // verify
        assertThat( violations ).isEmpty();
    }
}

然而，由于某种原因它无法解析注入点：org.jboss.weld.exceptions.UnsatisfiedResolutionException: WELD-001334: 无法满足类型为 ValidatorFactory 的依赖项，带有限定符。我猜我需要引用一个实现，而不是 ValidatorFactory.class。

I&#39;m trying to make a very simple testcase testing a custom validator in hibernate bean validation. The custom validator has an injection point.

Junit4, BeanValidation 6.1.5.Final, WeldUnit 2.0.0.Final

```java
public class AssertCrsForOffshoreTest extends TestBase {

    //CHECKSTYLE:OFF
    @Rule
//    public WeldInitiator weld = WeldInitiator.from( ValidatorFactory.class ).inject( this ).build();
    public WeldInitiator weld = WeldInitiator.from( ValidatorFactory.class ).build();
    //CHECKSTYLE:ON
    
    @Test
    public void testValidCrs() {

        // prepare test
        BroLocation location = createLocation();
        location.setCrs( BroConstants.CRS_WGS84 );
        BeanWithLocation bean = new BeanWithLocation(  location );

        // action
        Set&lt;ConstraintViolation&lt;BeanWithLocation&gt;&gt; violations = weld.select( ValidatorFactory.class ).get().getValidator().validate( bean );

        // verify
        assertThat( violations ).isEmpty();
    }


}

However, for some reason it cannot resolve the injection point: org.jboss.weld.exceptions.UnsatisfiedResolutionException: WELD-001334: Unsatisfied dependencies for type ValidatorFactory with qualifiers. I guess I need to refer to an implementation rather than the ValidatorFactory.class.

如Nikos在上面的评论部分所描述，我需要在fluent方法的from语句中添加ValidationExtension.class，并且将CDI库添加到测试范围中。

以下是完整的（可工作的解决方案）：

public class AssertCrsForOffshoreTest extends TestBase {

    //CHECKSTYLE:OFF
    // 初始化验证扩展并将测试类“注册”为GeometryServiceHelper模拟的生成器
    @Rule
    public WeldInitiator weld = WeldInitiator.from(ValidationExtension.class, AssertCrsForOffshoreTest.class).build();
    //CHECKSTYLE:ON

    @ApplicationScoped
    @Produces
    GeometryServiceHelper produceGeometryServiceHelper() throws GeometryServiceException {
        // 提供给自定义注释的模拟
        GeometryServiceHelper geometryService = mock(GeometryServiceHelper.class);
        when(geometryService.isOffshore(any(BroLocation.class))).thenReturn(true);
        return geometryService;
    }

    @Test
    public void testValidCrs() {

        // 准备测试数据
        BroLocation location = createLocation();
        location.setCrs(BroConstants.CRS_WGS84);
        BeanWithLocation bean = new BeanWithLocation(location);

        // 执行操作
        Set<ConstraintViolation<BeanWithLocation>> violations = weld.select(ValidatorFactory.class).get().getValidator().validate(bean);

        // 验证结果
        assertThat(violations).isEmpty();
    }
}

你还需要将beanvalidation的CDI扩展添加到单元测试的依赖范围中：

<dependency>
    <groupId>org.hibernate.validator</groupId>
    <artifactId>hibernate-validator-cdi</artifactId>
    <version>6.1.5.Final</version>
    <scope>test</scope>
</dependency>

注意：这只是你提供的代码片段的翻译，可能会因为上下文的缺失而导致某些表达不够准确。

public class AssertCrsForOffshoreTest extends TestBase {

    //CHECKSTYLE:OFF
    // intializes the validation extension and 'registers' the test class as producer of the GeometryServiceHelper  mock
    @Rule
    public WeldInitiator weld = WeldInitiator.from( ValidationExtension.class, AssertCrsForOffshoreTest.class  ).build();
    //CHECKSTYLE:ON

    @ApplicationScoped
    @Produces
    GeometryServiceHelper produceGeometryServiceHelper() throws GeometryServiceException {
        // mock provided to the custom annotation.
        GeometryServiceHelper geometryService = mock( GeometryServiceHelper.class );
        when( geometryService.isOffshore( any( BroLocation.class ) ) ).thenReturn( true );
        return  geometryService;
    }

    @Test
    public void testValidCrs() {

        // prepare test
        BroLocation location = createLocation();
        location.setCrs( BroConstants.CRS_WGS84 );
        BeanWithLocation bean = new BeanWithLocation(  location );

        // action
        Set<ConstraintViolation<BeanWithLocation>> violations = weld.select( ValidatorFactory.class ).get().getValidator().validate( bean );

        // verify
        assertThat( violations ).isEmpty();
    }
}

        <dependency>
            <groupId>org.hibernate.validator</groupId>
            <artifactId>hibernate-validator-cdi</artifactId>
            <version>6.1.5.Final</version>
